Jane’s choice: UNDERFLOOR HEATING

Compatible with many floor coverings, we look at the smart way to heat your home…

nderfloor heating, as the name suggests, is installed beneath the floor covering, offering an even temperature spread and luxurious warmth underfoot.

UWhat are the main types?

Electric or ‘dry’ systems involve a series of electric wires, often contained in a heat mat or cabling system, installed beneath or within the flooring. Water-based heating, also known as a ‘wet system’, comprises a series of pipes, connected to the boiler and concealed under the floor, that circulate warm water to heat the floor space.

Which type is best?

Electric systems are more affordable, but their running costs may be higher, so they are more suited to smaller spaces, such as tiled bathrooms. Water systems are more costly and disruptive to install, especially if a floor level alteration is required in order to accommodate the pipes.

Will it work with all types of flooring?

Tile and stone are best because they have good thermal conductivity, heating up the floor more quickly, and give more heat output to run more efficiently. Wood, laminate, carpet and vinyl can be used, though they may be less efficient. Check with your supplier.

When’s best to install?

Installing underfloor heating at the build stage is optimum if you are planning an extensive renovation, as you’ll be able to accommodate pipes before your flooring is laid. Do seek professional advice to help you calculate the amount of heat you’ll need to generate and take into account any heat loss afforded by your choice of floor covering. If you are fitting retrospectively, there are also a number of ‘retro fit’ options: low-profile and lightweight super-thin systems can be simply applied to existing sub floor surfaces without adjusting floor height.

Will I still need radiators?

If you live in a single-glazed property, you may still need to combine underfloor heating with radiators to achieve an ambient room temperature. Several of the latest designs are also created to fit neatly in between joists, while new apps, such as Hive, allow home owners to control their heating via smartphones.
