Research has shown that radiant heating is about 25% more energy efficient than forced air. But with Warmboard, that percentage is even higher due to greater control and lower water temperatures.
Low water temperatures do save energy, but how much? The US Energy Department estimates you can save $12–$30 per year for every 10ºF reduction in water temperature. Warmboard typically runs water temps between 80º-110ºF; the lowest in the industry. Other systems generally run between 140-180ºF.
Warmboard home is running 90ºF water.
Non-Warmboard home is running 140º water.
That difference of 50º means a potential savings of $600 to $1500 per year.
But over a few years, that adds up to a significant savings. And for those running on propane, expect even greater savings.
That is a huge savings! ... – Chuck V., Fairmont, VT}
But the benefits extend beyond that. Just as your car gets better gas mileage when your engine isn’t working as hard, or your phone keeps a longer battery life when not processing as much data, heating equipment, like boilers and water heaters, run more efficiently at lower temperatures, amplifying the savings. And when these appliances run at lower temperatures, their lifespan is extended, ensuring your investment lasts longer.
Today, more and more people are choosing alternative, eco-friendly heat sources such as geothermal and solar. These systems are limited however, unable to produce water above 120ºF without additional hardware. Since Warmboard is regularly using water below this threshold, interfacing is ideal. Other systems will require additional hardware to heat the water into the 140-180ºF range.
For architects looking for the ultimate in energy-efficiency, Warmboard does not disappoint. Warmboard radiant heat has been used in numerous Net Zero homes throughout the country. And with the potential to earn up to 15 LEED points, Warmboard can be an excellent tool towards achieving LEED Gold or Platinum. Warmboard radiant panels have also been used in numerous Solar Decathlon projects, several earning top marks.
