What is underfloor heating?

Underfloor heating systems utilise the entire floor area within a room as a heat emitter, delivering ultimate comfort effectively and efficiently.

Underfloor heating is another member of the heat emitter family. However, instead of being positioned on a wall, like a radiator or some fan convector models, an underfloor heating system is located within the floor allowing the entire floor to become a large surface area for emitting heat into the occupied living space of a room. Underfloor heating can effectively deliver ultimate comfort which is one of the reasons why its popularity is soaring.

Underfloor heating systems can be electric or wet – Grant’s Uflex and Uflex MINI systems are both wet underfloor heating systems. With wet underfloor heating systems, a series of flexible pipes are laid within the floor through which the hot water flows, transferring heat upwards and radiating heat evenly into the room. The effectiveness of the heat transfer is dependent on a suitable flooring material being fitted, such as tiles or stones, which permit excellent transfer and can be heated up to 29ºC.

There are different types of wet underfloor heating systems, but each system consists of the basic elements including floor insulation, a membrane base, the pipework and a layer of suitable screed. Grant’s Uflex system is a traditional underfloor heating arrangement with the pipework embedded within the floor construction, clipped into place and covered with a flow screed 75mm in thickness. The Uflex MINI system differs to the Uflex arrangement in that instead of staples holding the pipework in place, the flexible pipes are clipped into castellations within large, self-adhesive panels and a self-levelling screed is poured over the top which is between 15mm – 20mm in depth, making for a quicker installation and faster drying period.
