What is underfloor heating?

Basically, underfloor heating is a central heating system which works from the floor upwards, warming the air through conduction and radiation. Heat is generated by electricity passing through conductive cables, film or mesh, or by hot water from a boiler, running through a network of pipes. These are then hidden under the floor covering, whether tiles, wood or laminate.

Under tile heating has seen an enormous increase in popularity in the UK in recent years and is commonly used in chilly north European countries. It has been around since the Romans built their original hypocaust systems which used low level furnaces to heat air which was circulated through the space below the stone floors of their villas and bath houses. Different variations have continued to be used throughout the ages, culminating in the modern underfloor heating systems available today.

Once seen as an expensive luxury by the British, it has evolved to become an affordable alternative to traditional heating. A range of technical developments have also made it more efficient and easier to install. There are two different ways of installation, depending on the system you choose and the type of flooring you have. Floor heating systems can either have a layer of screed poured over them, or can simply be fixed to the sub-floor. To avoid wasting heat, underfloor heating insulation is placed underneath. These systems can be used throughout an entire building or be limited to one or two rooms, and often run in tandem with traditional systems.
