Flexel Electric Underfloor Heating Systems

Our Flexel electric underfloor heating systems are an efficient, economical and aesthetically pleasing way to heat your home.

Whether you want a primary source of heat*, or simply want to take the chill off floor tiles, the range of floor heating systems from Flexel will meet your needs.

Our electric underfloor heating film, cable and mats are quick and easy to install. Many of our products come with a lifetime guarantee.

* Underfloor heating can be used as a primary heating source, However rooms with potentially high heat losses like conservatories or areas that have limited free floor space available may need a supplementary heat source on very cold days.

Why choose electric underfloor heating?

Our electric underfloor heating systems utilise radiant heat. This heats the objects in the room, while traditional convection heaters heat the air. Water-based radiators rely on air circulation.

The radiator heats the air, the warm air rises and the cycle continues. However, this can cause dust and other allergens to circulate and causes temperature differentials between the ceiling and floor.

Radiant heat produces a much more even temperature. What’s more, using underfloor heating rather than radiators frees up wall space.

Electric underfloor heating is convenient, cost effective and environmentally friendly.

Electricity – The Fuel Of The Future:

Electric power is the future for heating. Dwindling supplies of North Sea gas, the uncertainty of imported gas supplies, the volatility of oil prices and the commitment to reduce the UK’s carbon footprint all point towards electricity as the fuel of the future. The country is moving towards a low carbon future, with electricity to be generated by nuclear power and sustainable sources. Electric heating is 100% efficient and carbon neutral at the point of use. Electric heating systems are compatible with microgeneration technologies. As more low carbon and renewable sources become available, we will increasingly see electric heating favoured over gas.

Frequently Asked Questions

Underfloor heating systems utilise radiant heat. This far infrared heating system heats objects in the room. This is opposed to traditional central heating systems, which heat the air.

Categories: FAQs, Underfloor Heating

Traditional central heating systems work by heating water in the radiator. This then heats the air which creates air currents as warm air rises and cold air falls due to differences in their density. This creates a temperature differential in the room with the ceiling space being heated first. This can create a stuffy environment and can result in an uncomfortable feeling of “hot head / cold feet”.

Radiant heat is the most efficient form of heat distribution available. The objects in the room are heated first and they then gently warm the surrounding air. This means that the air temperatures can be lowered in the room whilst still maintaining comfort levels, resulting in a reduction in heating bills.

As the air does not circulate there are no draughts created. Dust is not circulated in the room which brings higher comfort levels, especially for allergy sufferers. There is more even vertical heat distribution throughout the room which is far closer to the ideal distribution.

Underfloor heating systems can be installed under almost any surface. The systems are also completely invisible and quiet in operation. Conventional warm water radiators do not contribute to the aesthetics of a room and can reduce room space. Installing a radiant floor or ceiling heating system allows more flexibility in creating the perfect living environment.

Installing Ecomax insulation boards is highly recommended when fitting Flexel International cable mats or loose heating cable. The insulation boards will dramatically cut warm up times. This will mean less energy is used heating the floor. As a result, your bills will be lower.

While it is highly recommended that you install insulation boards under cable mats or loose cable, it is not necessary if you cannot build the floor up.

However, if you are installing EcoFilm heating element, it is vital that you use the EcoMax-Lite insulation. This will protect the element from any moisture in the sub-floor, which can cause nuisance tripping of the RCD. The insulation also provides excellent sound insulation, which is vital when using a laminate floor covering.

Whatever underfloor heating system you use, it is sensible to invest in proper insulation. This will keep your system running efficiently and save you money over the life of the system.

Underfloor HeatingHeat Up Time
Timber sub-floor with 10mm Ecomax insulation0.5 hours
Concrete sub-floor with 10mm Ecomax insulation 1 hour
Concrete Sub-floor with insulation below the concrete slab 2-5 hours
Un-insulated concrete3-8+ hours

There are many benefits of electric underfloor heating compared to traditional central heating systems. Flexel underfloor heating systems utilise radiant heat. This uses infrared energy to heat the people and objects in the room. This means that the overall temperature can be lowered will still maintaining a comfortable environment.

Traditional radiators heat the air in the room. This causes air circulation, as the changes in density cause hot air to rise and cold air to fall. As well as causing temperature differentials in the room (it will be hotter nearer the ceiling compared to the floor), the circulating air can also move dust and other allergens around the room.

This has obvious implications to sufferers of asthma and similar conditions. Radiant underfloor heating does not cause air circulation, which means allergens are not spread around the room. Other benefits include:

  • • Luxury of a heated floor, especially in winter
  • • Keeps wall space free from radiators
  • • Low surface temperature (typically 27-30°C, compared to 65-80°C for a conventional radiator system)
  • • Reduced temperature differences and reduced dust circulation.

Electric underfloor heating from Flexel International can cost as little as 5p per square meter,

This is based on running the system for 7 hours a day. While exact costs will depend on your own individual tariff, insulation is a much bigger influence on the running costs of underfloor heating. The better insulated the floor, the quicker the warm up times will be and then less energy will be used. Ecomax insulation boards will dramatically reduce warm up times, saving you money every time you use your underfloor heating system.

Some customers may consider not using insulation boards as they are concerned about the floor build up. However, using 6mm insulation boards, along with our ultrathin cable mats should only result in a total build-up of 10mm.

That is not a lot, when you consider the savings you will make in running costs. Running costs can also be affected by the heat losses in the room. Areas with high heat losses, such as conservatories can see higher running costs.

In this case, you may want to consider installing our 200W/m2 EcoFloor cable mat. The higher power output means your underfloor heating system will reach temperature quicker, to compensate for the heat losses. Many people still view electric underfloor heating as an expensive option. However, the installation and running costs provide excellent value for money.
