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 Warmboard’s 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, even with control systems that attempt 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.

One of Warmboard’s greatest advantages is its compatibility with virtually all floor coverings. Warmboard works particularly well with hardwoods, delivers ample radiant heat through even the plushest carpeting, and tile or stone can be set over it using conventional methods. Warmboard is the one radiant panel that doesn’t ask you to compromise your floor covering choices. For more detailed information, please see our install guide.

ON COSTS
When considered solely as an individual element, Warmboard is not inexpensive. However, when viewed as part of a complete radiant system, Warmboard proves it’s value. Financially speaking, Warmboard is extremely competitive with systems that simply do not perform nearly as well. Additionally, here are some other points to consider:

  • Warmboard’s 12” on-center tubing spacing outperforms all other panels, even those using 6″ on center tubing. This spacing also results in lower material and labor costs, as well as other hidden expenses.
  • Warmboard’s patented design allows most installations to operate with water temperatures well below 120° F. Low water temperatures give you the option of using condensing boilers, solar, low cost, dedicated, conventional water heaters or even ultra high-efficiency ground source heat pumps. Lower water temperatures also allows for more flooring options.
  • Radiant heating cuts average energy use as much as 20% over forced-air systems, and the low water temperatures typical of Warmboard installations cut energy bills even more (View a technical water temperature chart).
  • Warmboard systems are easily zoned, further reducing energy usage by heating only the desired rooms or regions. Fast response means you won’t wait a long time to heat up that guest room when it is unexpectedly needed.
  • Radiant heating is ideal for cathedral and open beamed ceilings because energy is not wasted heating high spaces.
  • "High Velocity" air conditioning is a perfect match with a Warmboard Radiant System.
