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
