Why is underfloor heating coupled with a heat pump so highly rated?
A. The lower the temperature of the heated water, the better the heat pump’s efficiency. Since standard radiators can reach as high as 80 deg.C (175 deg.F), far hotter than a heat pump can achieve, you will have to significantly increase the area of the radiators to be able to utilise the working temperature of 50 deg.C (122 deg.F), from a heat pump. However, if the water temperature can be further reduced to around 35 deg.C or less, then there is a considerable energy benefit. Underfloor heating pipes can give sufficient heat at these low temperatures and are therefore a good match with a heat pump. This system works best in insulated homes where the heat required is less than 50watts/sq.m. of floor area. For the average older house, the floor would have to be too warm to provide full heating. It is important to realise that heat pumps like lower temperatures and higher water flow within the uderfloor pipes. This means more pipe and a lower pressure drop than average. MAKE SURE THAT T
