Warmboard simplifies the design process because it has incredible reserves of performance. In the past, the low conductivity of many radiant panels limited performance so much that they could barely keep up with heat loads even when running at “red line”. These systems would often require 6″ spacing in some areas, and 9″ or 12″ in still other areas just to barely keep up with varying heat loads.

Because of Warmboard¹s high performance, our 12″ tube spacing will produce more output than even 6″ spacing in thin slab installations. This means that tubing spacing is no longer a critical design consideration.

Slab systems can take hours or days to heat up. With such a large delay between when a thermostat first calls for heat and when heat finally comes out of the slab, undershoot and overshoot are quite common problems. Of course control systems can be designed to mitigate this problem. Warmboard heats up in minutes – not hours or days. This means that getting the design of the control system just right is less critical. In fact, many Warmboard systems control beautifully with little more than a few room thermostats and on/off wax zone actuators.

What our customers say:

“I am truly amazed at how comfortable, responsive, and efficient the system is.”

I am truly amazed at how comfortable, responsive, and efficient the system is. It was the first time I have ever actually had an extended stay in a Warmboard home and I’m more sold on it than ever.

“If any radiant method can achieve full heating capabilities in a home, Warmboard can.”

NRT has 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.
