Is Underfloor heating a good idea?
Yes. Underfloor heating is an efficient method of distributing heat into a building to provide comfortable space heating (whether you use IHT or not). Lower temperatures (around 40°C) can be distributed over a larger area than the higher temperatures (around 70°C) needed for wall mounted radiators. Underfloor heating is invisible and clutter-free and radiates heat gently from ground level to avoid the convection and heat losses generated by wall mounted radiators. Underfloor heating makes a good match for distributing heat from a ground source heat pump – because a GSHP will deliver a higher coefficient of performance if a lower delivery temperature can be used. The underfloor piping can also be used to extract heat from the building in summer by circulating cold water to provide “critical period cooling”.
