Underfloor Heating

What is it?

Underfloor heating is an alternative solution to central heating and is a great add-on to homes with renewable heat technologies, such as Air Source Heat Pumps and Solar Thermal.

There are two types of underfloor heating available, either ‘dry’ systems which required electric cables to be installed beneath or within the flooring, or ‘wet’ systems which use piping to pump warm water through the flooring.

What is it suitable for?

Underfloor heating is suitable for all new build and retrofit projects and can be installed under a number of flooring types, including timber, tiles, carpet and vinyl.

As they operate at consistently low temperatures and distribute heat more evenly than radiators, they are a great add-on to renewable heat technologies, such as air source heat pumps and solar thermal.

Electric systems are generally most suited for smaller floor spaces as the cables are flexible enough to bend around small or awkward spaces, such as around toilets and sinks.

On the other hand, water system are most suited to larger floor spaces as they are cheaper to run and maintain long-term, compared to electric.

How does it work?

Electric underfloor heating consists of a series of wires or electric heating sheets which are installed beneath or within the flooring. They're usually placed on top of a layer of screed and a layer of floor insulation to ensure optimum performance.

Water-based underfloor heating systems consist of a series of pipes connected to the boiler or renewables system which circulate warm water throughout the floor

What are the benefits?

  • There is no risk of burning due to low surface temperature

  • Works silently

  • Very low maintenance required

  • Long life span (50 years for underfloor heating pipe work)

  • Increased flexibility for furniture and furnishings due to all of the walls being free from radiators

  • Reduced risk of airborne spread pollen and bacteria due to less air movements, thereby improving the indoor air quality
