Underfloor heating – total comfort built in

Underfloor heating works by pumping temperature controlled warm water from a normal central heating boiler (or other hot water heating system), through jointless plastic tubing embedded in the floor. It provides warmth to a room from the floor up, unlike radiators that heat the ceiling space first. The standard operating temperature is 50˚C although it can work at temperatures as low as 35˚C, compared to 70˚C for radiators, making it more economic and environmentally friendly.

Underfloor heating can be linked to most heat sources including system, combi, and high efficiency boilers, range cookers, solar thermal hot water systems or ground source, air source and exhaust air heat pumps. However, solar thermal technology and heat pumps systems are ideally suited to work with underfloor heating, given its low operating temperatures.

Independent report findings
The European Association for Surface Heating and Cooling (Eu Ray) has now proved that using underfloor heating can deliver significant fuel savings against radiator-based systems.

It found that using underfloor heating combined with a ground source heat pump cuts energy consumption by an impressive 30% compared to radiators – and combining a heat pump unit and underfloor heating also means housebuilders can expect to reach Code 3 under the Code for Sustainable Homes.
However, if a building is heated using a condensing boiler, it will use 5% less energy if underfloor heating is installed than if radiators are used. This is due to the system delivering a near perfect temperature profile between the floor and the ceiling with 50% radiant heat released evenly and absorbed by people and objects in the room.
If an underfloor heating system is to be used as a total heating solution, it is possible to lower the average room temperature by up to 2˚C without affecting the level of comfort, and with each degree representing a reduction in fuel consumption of 6%. 

Overall, any building that uses underfloor heating has a better carbon footprint than one with a conventional heating system, and when combined with other low-energy technologies, such as heat pumps, this can influence the building’s rating towards Code levels 3, 4 and 5.

Underfloor heating benefits

  • No unsightly radiators
  • Use of whole wall space
  • Lower fuel bills
  • Ideal for use with other renewable technologies such as solar & heat pumps
  • Can help achieve quicker sales cycles for housebuilders
