"[I have] been extremely impressed with the ease of installation of Warmboard panels. If any radiant method can achieve full heating capabilities in a home, Warmboard can, and it can usually do so even with low temperature heating methods like geothermal heat pumps.In our experience, we can maximize a wood floor output at about 30 BTUs/sq ft at no more than 115 degree supply water temperature. With tile the situation is even better. That is typically enough output to satisfy all but the highest heat load spaces with floor heat alone, eliminating the need for secondary heat sources in almost all cases."
