Hippo toilet flush water saver

loftlegs loft insulation spacer

    The hippo is simply a bag which goes into the toilet cistern to save water every time you flush. Easy to fit, no tools required.


Water saving aerating shower

loftlegs loft insulation spacer

A water saving shower has an air intake at the base of the showerhead. It mixes air with the water to create a powerful shower effect, whilst using 20-30% less water. The air intake creates a back pressure to water passing through the showerhead, which in turn uses less water and less hot water energy. Our aerating showers can be combined with shower flow restrictors for further savings, especially in high water pressure areas.


Tap aerator flow restrictor

loftlegs loft insulation spacer

Many taps installed from new are generally free flowing which can use up to 4 times more water than necessary. For example, if you have a wash basin which is predominantly used for brushing teeth or washing hands, then it may not be necessary to have a high flow rate from your tap. We have a range of flow restricting aerators, which can reduce your water flow to as little as 2 litres per minute. Most people generally choose 4 or 6 litres per minute, which will generally reduce a standard tap flow down from around 9 or 10 litres per minute.


Shower stop valve

loftlegs loft insulation spacer

This little valve was initially created for motorhomes, caravans, and boats, but it can also be used around the home. Simply flick the switch to one side to cut off water flow to a shower.

These valves are really good for people that have hot and cold mixer taps to the shower fitting which needs to be balanced to get the right temperature. When a shower stop valve is fitted, you only need to adjust the hot and cold taps once to balance the water temperature each time you use the shower enabling you to turn the flow of water off without re-balancing.


Combisave

loftlegs loft insulation spacer

The Combisave valve can save you thousands of litres of water per year. It works by reducing water flow to the hot tap whilst the combination boiler is heating up. This can actually help the water come through to your hot tap a second or two faster, but it also can save the 10 to 15 L of cold water which is wasted before your hot water comes through. Combi save also enables the boiler hot water preheat to be turned off, which can save as much as £50 of gas per year, simply by changing a boiler setting.


Shower flow restrictor

loftlegs loft insulation spacer

In some cases it may be necessary to restrict the amount of water which comes out of your shower. This is often needed in high-pressure water areas, where it may even be uncomfortable underneath the shower if the pressure is too high. A simple restrictor can be screwed onto the end of the shower hose to reduce the amount of water used. Our pack can reduce water flow to 8 litres or 6 litres of water per minute. There is an option to change the small flow restrictor inside, no tools required.


Shower Timer

loftlegs loft insulation spacer

Shower timers are a quick and easy way to check you are not using more water and hot water energy than necessary. They also help to train you to enjoy your shower efficiently. It is actually possible to have a shower in as little as three minutes. The average shower time is around eight minutes. A four-minute shower timer can help you use half as much water and hot water heating energy every time you use the shower.


WC stop Toilet Flush Water Saver

loftlegs loft insulation spacer

This really simple device acts as a weight to immediately close the toilet flush valve on most two button flush toilets. The maybe many occasions where you simply need a quick rinse down of the toilet pan, where even a partial flush is more than necessary. With the WC stop, you hold your finger down on the toilet flush for a full flush, as soon as you release your finger from the flush button, the flush stops. Can reduce the water consumption in toilet by 50%

Most PIR's do require a neutral however we do have a non neutral 200w wall mounted PIR which can be found here

What is an LED?

What is an LED?

A Light Emitting Diode (LED) is a device consisting of a semiconductor that emits light energy when an electrical current is passed through it. LEDs can be used for a wide range of lighting applications. It is predicted that LED lights are the future for energy-efficient home lighting.

Does a GU10 LED bulb give the same brightness as my old halogen bulb?

Does a GU10 LED bulb give the same brightness as my old halogen bulb?

Yes, Low Energy Supermarket’s LED bulbs are the perfect replacement for traditional halogen bulbs.

What does IP65 mean?

What does IP65 mean?

The IP, or Ingress Protection rating of an electrical product is a guide that is used to detail the strength of the enclosure that surrounds the electrical components.
In the case of LED lights bulbs, the IP-rating measures the tolerance to the effect of dust particles and the level of protection against water or liquids. IP65 means that the LED bulb is totally protected against dust and can withstand low-pressure jets of water from all directions - with limited ingress acceptable.

Do I have to have fire-rated fittings?

Do I have to have fire-rated fittings?

Ceilings provide an important barrier that helps to prevent the spread of fire and noise between the floors of a building. Installing recessed downlights punctures this barrier and can reduce the effectiveness of this safety barrier.

Installing fire rated downlights helps to protect your premises from the effects of both fire and noise pollution and aids compliance with new building regulations governing the installation of downlights. Made from intumescent materials, fire rated downlights seal the gap between the ceiling and the fitting to offer up to 90 minutes protection against the spread of fire into the void spaces within your ceiling / loft space.

Fire rated downlights are more expensive than non-fire rated downlights. However, the worst decision you can make is to buy cheaper models that look exactly the same only to find out from the electrician fitting them, that building regulations require fire rated downlights for that situation

Do the LED Tube lights require a re-wire?

Do the LED Tube lights require a re-wire?

Yes but it is very straightforward, we supply full detailed instructions of how to do the re-wire.

How does ambient temperature affect the performance of LED Lights?

The performance of LED lights can be adversely affected by severe changes in ambient temperature or operating the bulbs outside the recommended temperature range. LED bulbs are tested at an ambient temperature of 25 degrees Celsius, which is adequate for most domestic environments.
However, in more challenging environments, with extreme levels of hot or cold ambient conditions, there may be a decrease in light levels together with an adverse effect on the life span of the bulb. This is why there are specially designed LED lights for use in hazardous and extreme conditions.

Will LED bulbs fit into my old light fixtures?

Will LED bulbs fit into my old light fixtures?

We have two length types of bulbs (58mm & 61mm) so yes these bulbs will retrofit into existing units but you will need to check which length is most suitable for your fitting.

What fittings should I have for my bathroom?

What fittings should I have for my bathroom?

Any fittings being placed within a bathroom/wet room/shower room should not only be Fire Rated but also be waterproof and hold a suitable certification of IP65 or higher to comply with current building regulations for bathrooms.

How Water Immersion Heater Timer

loftlegs loft insulation spacer

    Timer switches give you control over your electricity usage and prevent things from overrunning, or staying on for longer than planned. Items like hot water immersion heaters can use a lot of electricity, which is annoying if they are accidentally left on. Timer switches also have a wide range of other usage such as controlling lighting, extract ventilation, heating.


Infrared panel heaters

loftlegs loft insulation spacer

Far infrared panel heaters are starting to become more common. These can work more effectively than cheap oil radiators or fan heaters because they do not need to heat all of the air within the room. Infrared panel heaters work by radiating heat, the same type of heat which you feel from the sun. Infrared red panel heaters heat up people and objects within the room, which is especially effective for large spaces. Infrared panel heaters can use 2 to 3 times less electricity than high powered oil radiators, fan heaters, or traditional panel wall heaters as they require much lower power input. For example, a 600 W infrared panel heater could heat the same space as a 2000W oil radiator. Now that the electricity generated for grid supply is becoming greener with more and more wind/solar generation, low-power infrared panel heaters are becoming an eco-friendly option.


Countdown timer and time delay switch

loftlegs loft insulation spacer

Time delay switches ensure things are not left on for any longer than necessary. These are commonly used in places like communal stairwells leading to flats to ensure the light not left on. We also have time delay switches which can be used with power sockets, to automatically turn off power after 1, 3, or 6 hours which is a great way of improving electrical safety and stopping any phantom loads / standby power consumption.


LED lighting

loftlegs loft insulation spacer

Lighting has now become much more efficient. Old tungsten light fittings only gave out around 12 lumens brightness of light per watt of electricity used, modern LED light fittings can now give out more than 100 lumens brightness of light per watt of electricity used. Energy saving LED light bulbs and LED spotlight fittings can now save more money around the home than compact flourescent bulbs and they last longer. LED tube lights and LED panel lights can save a huge amount of money in commercial properties like shops and offices where their installation pays for itself very quickly, in some cases less than one year if there are long operational hours.


Solar Panels

loftlegs loft insulation spacer

Try creating your own electricity, whether it be for a solar powered light to the shed at the end of your garden, or maybe even an off grid holiday home or workplace. We have a wide range of solar panels, solar charge controllers, solar generators, and solar battery kits which can help you to do this. You can also use our solar calculator to help you decide what size solar panels and battery banks you may need for your project.


Compact Fluorescent Lighting CFL’s

loftlegs loft insulation spacer

CFL compact fluorescent lighting has been around for years. We have kept CFL energy saving lighting as part of our range as it is still a quick and cheap fix to saving electricity. CFL light bulbs are still generally cheaper than the modern LED light bulbs, although LED light bulbs do use a few watts less electricity


Photocell Timer

loftlegs loft insulation spacer

Most people simply fit a photocell switch if they want to ensure there lights are not accidentally left on during the daytime. The disadvantage of a standard photocell switch is that the lights will stay on all night, unless the photocell is connected to a separate timer switch. We have an all in one photocell timer switch, which can turn your light on at dusk, turn off at say midnight, turn on at 7 AM, turn off Dawn automatically. Time settings are adjustable. This gives you the convenience of automatic lighting and ensures your lights are not left on throughout the night or during daytime


LED Night Light

loftlegs loft insulation spacer

We introduced our range of LED nightlights as we appreciate that some people, especially when there are children in the house, may wish to leave a landing on throughout the night. Instead of having an 11w energy-saving light fitting running all night, why not use our LED nightlight which uses only 0.5 W, as little as 1p per week


One Cup Kettle

loftlegs loft insulation spacer

Consider buying a one cup kettle. Instead of boiling 3 or 4 cups of water each time you switch the kettle on, a 1 cup kettle will simply boils just one cup of water each time. We have tested these on our energy monitors, and they can actually save you around £20-30 of electricity each year, plus doing your little bit for the environment


PIR occupancy sensors for fans and lighting

loftlegs loft insulation spacer

Passive infrared (PIR) occupancy sensors detect when there is movement, generally up to 8 m away from the sensor.They will automatically turn on lighting or fans to a room when they detect a person in the area. PIR occupancy sensors will then keep lighting on so long as there is movement in the area of the sensor. When the person has left the room, the occupancy sensor will turn the lighting off again, say five minutes after the person leaves the room.The lighting in the room stays on so long as there is movement which constantly resets the five-minute countdown timer to prevent the light from turning (time settings adjustable).Obviously, this is a great way of ensuring items are not left on when there is nobody in the room. A great example, is storerooms to the back of shops which may have several strip light fittings which stay on all day, whereas, people may only be going in and out of the room once or twice an hour. PIR occupancy sensors are suitable for many other spaces like toilets, utility rooms, occasional use areas such as circulation corridors. They can reduce your lighting energy usage by as much as 30 to 50%

Why do I need to replace my dimmer switch?

Why do I need to replace my dimmer switch?

The minimum wattage figure on the dimmer switch is too high, typically the majority of leading edge dimmer switches are 60 watts which is way too high for operation with dimmable LED bulbs. This is why you need an LED compatible dimmer switch for use with dimmable LED bulbs.

Why are LED lights considered a green technology?

Why are LED lights considered a green technology?

LED bulbs are the only truly eco-friendly lighting solution. Unlike traditional forms of lighting where the majority of the electrical energy is given off in the form of heat, LED bulbs operate at around 80% efficiency. This means that an LED bulb converts 80% of its electricity into light energy with very little given off as heat, compared to an incandescent bulb that only turns 20% of the electricity it uses into light energy.

ETRV's

loftlegs loft insulation spacer

Traditional Thermostatic Radiator Valves (TRVs) sense the air temperature around them and regulate the flow of water through the radiator which they are fitted to. They do not control the boiler. Inside the Traditional Thermostatic TRV Head is a sensor containing a wax or liquid material which expands as the room temperature warms up and contracts when it cools down. They have limited accuracy, hence why they typically only have 1,2,3,4,5 temperature settings.

This new 2017 Model Electronic TRV (eTRV), has digital temperature control so you can set your room temperature to 21 degrees centigrade or whatever temperature you desire. Its biggest advantage, is you can also use these eTRV's to program on/off and temperature times for every radiator in your building which can lead to significant energy savings of 20-25%. For every radiator not turned on unnecessarily, this effectively reduces the length of your heating circuit which means the water temperature in the central heating loop returns to the boiler at a higher temperature. Most Modern boilers will then use their economy settings to prevent boiler firing until heating loop cools with in turn saves fuel. This eTRV allows for multi-room zoned temperature control of your house or workplace.

Setting a TRV to a higher temperature will not make the room heat up any faster. How quickly the room heats up depends on the boiler size and radiator size. Turning a TRV to a lower setting will result in the room being controlled at a lower comfortable temperature and saves energy. TRVs need a free flow of air to sense the temperature so they must not be covered by curtains or blocked by furniture.


Radflek

loftlegs loft insulation spacer

Radflek radiator reflectors, reduces your heating bill by reflecting wasted energy back into your room rather than heating up the wall and the street outside.


LED lighting

loftlegs loft insulation spacer

LED spot lights use 90% less electricity than halogen or tugsten bulbs and last many times longer with great energy saving potential. Payback in only 2-3 months for long halogen light working hours


Chimney sheep/balloon

loftlegs loft insulation spacer

Chimney Sheep Chimney Draught Excluders are designed to be pushed into the narrow part of the chimney above the fireplace, used when the fire is out and the central heating is on.

A huge amount of warm air is drawn up the chimney throughout the day which causes draughts in rooms and loss of heated air.

It has been calculated that for an average sized flue these chimney draught excluders can save you £23 per year off your heating bills for EACH chimney, with the added benefit of reducing draughts within rooms. If you have several chimneys then the savings will be much higher.

The Chimney draught excluder is made of Herdwick wool on a handle. The wool squashes into the shape of the chimney throat or flue, and holds itself in place. When you want to light the fire this design of chimney draught excluder can simply be pulled and put it in a bag. When the fire is completely cold you can put it back in again. It's easy to use and can be used over and over again.

Each chimney draught excluder comes with a 300mm handle. If the distance from the top of the fireplace to the chimney throat is more than the length of a ruler then you may need to get an extension rod, available separately.

These chimney draught excluders have the huge advantage over similar products in that they can be easily taken out and re-fitted each time the fire is lit. There are many buildings where fires may only be used on special occasions such as only over Christmas.

Other advantages, Can stop noise coming down your chimney; saves money, sustainable material, stops cold draughts coming down your chimney for example during windy days, stops debris falling down your chimney like soot and hailstones.


Plug in thermostat

loftlegs loft insulation spacer

Plugin Digital thermostat. The thermostat will stop and start your heater as the temperature rises and falls. Ideal for tubular heaters, fan heaters, oil filled heaters, convection heaters and electric radiators


Hot water jacket

loftlegs loft insulation spacer

A Hot Water Insulation Jacket will reduce your gas or electricity bills by reducing the cost of your hot water heating.

A poorly insulated hot water cylinder will constantly lose heat into the surrounding area which you may not want to be heating. For example, an electric immersion hot water cylinder without any insulation will lose so much heat it will actually heat the property for you, but this is electric heating which is costly to run.

Potential Savings* that can be gained by increasing the thickness of your hot water cylinder insulation are given below. You can also add further insulation to your hot water cylinder where your current insulation jacket is fairly thin. You simply add an additional 80mm thick insulation jacket over the top.


Hot water saving shower

loftlegs loft insulation spacer

water and energy saving showers work best with hot and cold mixer showers, thermostatic mixer showers and power showers. Eco Shower heads can be used with electric showers but they will generally not be able to give water or energy savings as electric showers regulates their own water flow. If this Eco shower head is used with an electric shower it will have the benefit of increasing pressure due to the aeration which is especially beneficial on low power 8 - 9.5 KW showers during winter when the water flow rate is very slow.


Count down timer

loftlegs loft insulation spacer

Our Lowenergie Countdown Power Saver helps you to save energy, reduce your bills and protect the environment. This device can have great potential to turn off equipment which may accidentally be left on for long periods or overnight. Multi socket extension leads can be plugged into this power saver to allow four or more devices to be fully disconnected from the power. Standard version has 1, 3 and 6 hour time settings


Window and door draught proofing

loftlegs loft insulation spacer

Your house or commercial property will loose heat during cold weather partly due to poor thermal insulation, but also due to air infiltration or the permeability of the building. Infiltration or permeability is measured in meters cubed per hour per square meter of floor area. A typical building built 1900 to 1990 will loose around 15-25 meter cubed of air per hour per square meter of floor area. This is due to natural leakage through the fabric of the building, but largely through gaps around windows and doors. Good use of draft proofing could reduce your air permeability to around 10-15 meters cubed per hour which is a good low cost way of reducing you heating bills.

Do I need to swap my current transformers?

Do I need to swap my current transformers?

Yes, standard electronic transformers can cause certain types of LED bulbs to flicker, resulting in permanent long-term damage to the LED bulb itself. This problem is most evident in 12V MR16 LED bulbs where a standard transformer does not provide a smooth flow of current, causing flickering problems. You may only need a transformer if you are buying 12v bulbs all 240 bulbs do not require a transformer, 12v bulbs are MR16, G4 and MR11. To avoid damaging your new LED bulbs it is always best to use LED drivers/transformers.

What does IP65 mean?

What does IP65 mean?

The IP, or Ingress Protection rating of an electrical product is a guide that is used to detail the strength of the enclosure that surrounds the electrical components.
In the case of LED lights bulbs, the IP-rating measures the tolerance to the effect of dust particles and the level of protection against water or liquids. IP65 means that the LED bulb is totally protected against dust and can withstand low-pressure jets of water from all directions - with limited ingress acceptable.

Does a GU10 LED bulb give the same brightness as my old halogen bulb?

Does a GU10 LED bulb give the same brightness as my old halogen bulb?

Yes, Low Energy Supermarket’s LED bulbs are the perfect replacement for traditional halogen bulbs.

How long do LED bulbs last?

How long do LED bulbs last?

LED light bulbs have a much longer life span compared to standard halogen bulbs. In fact LED bulbs last up to 50000 hours – that’s over 5 years of continuous operation. Once you install a LED light bulb you may never have to replace it.

About Us

About Us

At Low Energy Supermarket, we have the approach that reducing CO2 emissions and saving the planet doesn't mean becoming an ECO warrior, it just makes good money sense, with the added bonus of helping to control climate change and conserve energy.  
Using the energy saving products on this website and with a little investment, you will be amazed how much money saving can be done.

‘Spend a little now & start saving

Low Energy Supermarket has been established to provide a wide range of energy efficiency products on one site in order for you to upgrade either your domestic or commercial property.  In recent years the government has imposed energy performance certificates on sale or letting of property in a drive to create public awareness in energy efficiency in the hope their recommendations will be implemented to help reduce C02 emissions.  Energy improvements to you property can be of benefit on sale or letting by showing a good energy rating, but more importantly, investment in energy efficiency will significantly reduce your fuel bills which will otherwise carry on increasing as fossil fuels become less available.

We aim to provide low cost but good quality products for both commercial and domestic energy improvement applications.  For each product we will provide an indication of payback and typical cost savings.  The shorter the payback period, the quicker your energy saving investment is recouped through energy bill reduction.  Once your energy saving technology is repaid through your energy savings you can then enjoy much lower than average energy bills knowing you also have low carbon emissions protecting the environment.

Our range of ‘only energy saving products’ has now greatly improved and we have every intention of continued expansion.  We are also developing new energy saving products and continue working towards driving down the cost of carbon reduction.  We are strong believers that acceleration towards a low carbon economy should be implemented as quickly as possible to prevent further damage to Earth's climate.  We want to make quality energy saving technologies available to all at the best prices possible whilst allowing us to develop a wider range of energy saving products for you. 

If you have any questions about our products, the company or any issues with your order then please contact us.

How hot does an LED bulb get?

How hot does an LED bulb get?

LED bulbs run significantly cooler than other types of lighting like halogen or CFLs but they do get hot, but the heat is dissipated by metal heat sinks that take away the heat from the light source itself. Keeping them cool helps maintain the long lifespan of a LED bulb.

Are LED bulbs safe?

Are LED bulbs safe?

Yes! LED bulbs are referred to as solid state lighting technology and do not contain any harmful materials unlike certain other types of household lighting that contain toxic substances like mercury.

ETRV's

loftlegs loft insulation spacer

Traditional Thermostatic Radiator Valves (TRVs) sense the air temperature around them and regulate the flow of water through the radiator which they are fitted to. They do not control the boiler. Inside the Traditional Thermostatic TRV Head is a sensor containing a wax or liquid material which expands as the room temperature warms up and contracts when it cools down. They have limited accuracy, hence why they typically only have 1,2,3,4,5 temperature settings.

This new 2017 Model Electronic TRV (eTRV), has digital temperature control so you can set your room temperature to 21 degrees centigrade or whatever temperature you desire. Its biggest advantage, is you can also use these eTRV's to program on/off and temperature times for every radiator in your building which can lead to significant energy savings of 20-25%. For every radiator not turned on unnecessarily, this effectively reduces the length of your heating circuit which means the water temperature in the central heating loop returns to the boiler at a higher temperature. Most Modern boilers will then use their economy settings to prevent boiler firing until heating loop cools with in turn saves fuel. This eTRV allows for multi-room zoned temperature control of your house or workplace.

Setting a TRV to a higher temperature will not make the room heat up any faster. How quickly the room heats up depends on the boiler size and radiator size. Turning a TRV to a lower setting will result in the room being controlled at a lower comfortable temperature and saves energy. TRVs need a free flow of air to sense the temperature so they must not be covered by curtains or blocked by furniture.


Radflek

loftlegs loft insulation spacer

Radflek radiator reflectors, reduces your heating bill by reflecting wasted energy back into your room rather than heating up the wall and the street outside.


LED lighting

loftlegs loft insulation spacer

LED spot lights use 90% less electricity than halogen or tugsten bulbs and last many times longer with great energy saving potential. Payback in only 2-3 months for long halogen light working hours


Chimney sheep/balloon

loftlegs loft insulation spacer

Chimney Sheep Chimney Draught Excluders are designed to be pushed into the narrow part of the chimney above the fireplace, used when the fire is out and the central heating is on.

A huge amount of warm air is drawn up the chimney throughout the day which causes draughts in rooms and loss of heated air.

It has been calculated that for an average sized flue these chimney draught excluders can save you £23 per year off your heating bills for EACH chimney, with the added benefit of reducing draughts within rooms. If you have several chimneys then the savings will be much higher.

The Chimney draught excluder is made of Herdwick wool on a handle. The wool squashes into the shape of the chimney throat or flue, and holds itself in place. When you want to light the fire this design of chimney draught excluder can simply be pulled and put it in a bag. When the fire is completely cold you can put it back in again. It's easy to use and can be used over and over again.

Each chimney draught excluder comes with a 300mm handle. If the distance from the top of the fireplace to the chimney throat is more than the length of a ruler then you may need to get an extension rod, available separately.

These chimney draught excluders have the huge advantage over similar products in that they can be easily taken out and re-fitted each time the fire is lit. There are many buildings where fires may only be used on special occasions such as only over Christmas.

Other advantages, Can stop noise coming down your chimney; saves money, sustainable material, stops cold draughts coming down your chimney for example during windy days, stops debris falling down your chimney like soot and hailstones.


Plug in thermostat

loftlegs loft insulation spacer

Plugin Digital thermostat. The thermostat will stop and start your heater as the temperature rises and falls. Ideal for tubular heaters, fan heaters, oil filled heaters, convection heaters and electric radiators


Hot water jacket

loftlegs loft insulation spacer

A Hot Water Insulation Jacket will reduce your gas or electricity bills by reducing the cost of your hot water heating.

A poorly insulated hot water cylinder will constantly lose heat into the surrounding area which you may not want to be heating. For example, an electric immersion hot water cylinder without any insulation will lose so much heat it will actually heat the property for you, but this is electric heating which is costly to run.

Potential Savings* that can be gained by increasing the thickness of your hot water cylinder insulation are given below. You can also add further insulation to your hot water cylinder where your current insulation jacket is fairly thin. You simply add an additional 80mm thick insulation jacket over the top.


Hot water saving shower

loftlegs loft insulation spacer

water and energy saving showers work best with hot and cold mixer showers, thermostatic mixer showers and power showers. Eco Shower heads can be used with electric showers but they will generally not be able to give water or energy savings as electric showers regulates their own water flow. If this Eco shower head is used with an electric shower it will have the benefit of increasing pressure due to the aeration which is especially beneficial on low power 8 - 9.5 KW showers during winter when the water flow rate is very slow.


Count down timer

loftlegs loft insulation spacer

Our Lowenergie Countdown Power Saver helps you to save energy, reduce your bills and protect the environment. This device can have great potential to turn off equipment which may accidentally be left on for long periods or overnight. Multi socket extension leads can be plugged into this power saver to allow four or more devices to be fully disconnected from the power. Standard version has 1, 3 and 6 hour time settings


Window and door draught proofing

loftlegs loft insulation spacer

Your house or commercial property will loose heat during cold weather partly due to poor thermal insulation, but also due to air infiltration or the permeability of the building. Infiltration or permeability is measured in meters cubed per hour per square meter of floor area. A typical building built 1900 to 1990 will loose around 15-25 meter cubed of air per hour per square meter of floor area. This is due to natural leakage through the fabric of the building, but largely through gaps around windows and doors. Good use of draft proofing could reduce your air permeability to around 10-15 meters cubed per hour which is a good low cost way of reducing you heating bills.

How Water Immersion Heater Timer

loftlegs loft insulation spacer

    Timer switches give you control over your electricity usage and prevent things from overrunning, or staying on for longer than planned. Items like hot water immersion heaters can use a lot of electricity, which is annoying if they are accidentally left on. Timer switches also have a wide range of other usage such as controlling lighting, extract ventilation, heating.


Infrared panel heaters

loftlegs loft insulation spacer

Far infrared panel heaters are starting to become more common. These can work more effectively than cheap oil radiators or fan heaters because they do not need to heat all of the air within the room. Infrared panel heaters work by radiating heat, the same type of heat which you feel from the sun. Infrared red panel heaters heat up people and objects within the room, which is especially effective for large spaces. Infrared panel heaters can use 2 to 3 times less electricity than high powered oil radiators, fan heaters, or traditional panel wall heaters as they require much lower power input. For example, a 600 W infrared panel heater could heat the same space as a 2000W oil radiator. Now that the electricity generated for grid supply is becoming greener with more and more wind/solar generation, low-power infrared panel heaters are becoming an eco-friendly option.


Countdown timer and time delay switch

loftlegs loft insulation spacer

Time delay switches ensure things are not left on for any longer than necessary. These are commonly used in places like communal stairwells leading to flats to ensure the light not left on. We also have time delay switches which can be used with power sockets, to automatically turn off power after 1, 3, or 6 hours which is a great way of improving electrical safety and stopping any phantom loads / standby power consumption.


LED lighting

loftlegs loft insulation spacer

Lighting has now become much more efficient. Old tungsten light fittings only gave out around 12 lumens brightness of light per watt of electricity used, modern LED light fittings can now give out more than 100 lumens brightness of light per watt of electricity used. Energy saving LED light bulbs and LED spotlight fittings can now save more money around the home than compact flourescent bulbs and they last longer. LED tube lights and LED panel lights can save a huge amount of money in commercial properties like shops and offices where their installation pays for itself very quickly, in some cases less than one year if there are long operational hours.


Solar Panels

loftlegs loft insulation spacer

Try creating your own electricity, whether it be for a solar powered light to the shed at the end of your garden, or maybe even an off grid holiday home or workplace. We have a wide range of solar panels, solar charge controllers, solar generators, and solar battery kits which can help you to do this. You can also use our solar calculator to help you decide what size solar panels and battery banks you may need for your project.


Compact Fluorescent Lighting CFL’s

loftlegs loft insulation spacer

CFL compact fluorescent lighting has been around for years. We have kept CFL energy saving lighting as part of our range as it is still a quick and cheap fix to saving electricity. CFL light bulbs are still generally cheaper than the modern LED light bulbs, although LED light bulbs do use a few watts less electricity


Photocell Timer

loftlegs loft insulation spacer

Most people simply fit a photocell switch if they want to ensure there lights are not accidentally left on during the daytime. The disadvantage of a standard photocell switch is that the lights will stay on all night, unless the photocell is connected to a separate timer switch. We have an all in one photocell timer switch, which can turn your light on at dusk, turn off at say midnight, turn on at 7 AM, turn off Dawn automatically. Time settings are adjustable. This gives you the convenience of automatic lighting and ensures your lights are not left on throughout the night or during daytime


LED Night Light

loftlegs loft insulation spacer

We introduced our range of LED nightlights as we appreciate that some people, especially when there are children in the house, may wish to leave a landing on throughout the night. Instead of having an 11w energy-saving light fitting running all night, why not use our LED nightlight which uses only 0.5 W, as little as 1p per week


One Cup Kettle

loftlegs loft insulation spacer

Consider buying a one cup kettle. Instead of boiling 3 or 4 cups of water each time you switch the kettle on, a 1 cup kettle will simply boils just one cup of water each time. We have tested these on our energy monitors, and they can actually save you around £20-30 of electricity each year, plus doing your little bit for the environment


PIR occupancy sensors for fans and lighting

loftlegs loft insulation spacer

Passive infrared (PIR) occupancy sensors detect when there is movement, generally up to 8 m away from the sensor.They will automatically turn on lighting or fans to a room when they detect a person in the area. PIR occupancy sensors will then keep lighting on so long as there is movement in the area of the sensor. When the person has left the room, the occupancy sensor will turn the lighting off again, say five minutes after the person leaves the room.The lighting in the room stays on so long as there is movement which constantly resets the five-minute countdown timer to prevent the light from turning (time settings adjustable).Obviously, this is a great way of ensuring items are not left on when there is nobody in the room. A great example, is storerooms to the back of shops which may have several strip light fittings which stay on all day, whereas, people may only be going in and out of the room once or twice an hour. PIR occupancy sensors are suitable for many other spaces like toilets, utility rooms, occasional use areas such as circulation corridors. They can reduce your lighting energy usage by as much as 30 to 50%

Yes but it is very straightforward, we supply full detailed instructions of how to do the re-wire.

How does ambient temperature affect the performance of LED Lights?

The performance of LED lights can be adversely affected by severe changes in ambient temperature or operating the bulbs outside the recommended temperature range. LED bulbs are tested at an ambient temperature of 25 degrees Celsius, which is adequate for most domestic environments.
However, in more challenging environments, with extreme levels of hot or cold ambient conditions, there may be a decrease in light levels together with an adverse effect on the life span of the bulb. This is why there are specially designed LED lights for use in hazardous and extreme conditions.

Do I need to swap my current transformers?

Do I need to swap my current transformers?

Yes, standard electronic transformers can cause certain types of LED bulbs to flicker, resulting in permanent long-term damage to the LED bulb itself. This problem is most evident in 12V MR16 LED bulbs where a standard transformer does not provide a smooth flow of current, causing flickering problems. You may only need a transformer if you are buying 12v bulbs all 240 bulbs do not require a transformer, 12v bulbs are MR16, G4 and MR11. To avoid damaging your new LED bulbs it is always best to use LED drivers/transformers.

Which colour is best for indoor use?
