Given these considerations, it's no surprise that studies have found radiant heat to perform at least 25 percent more efficiently than forced air. Whether or not a radiant system provides any further savings usually depends on its design. The traditional design hinges on gypsum concrete, which has a significant downside: it takes a long time to heat up and cool off. That's why industry leader Warmboard swaps concrete for aluminum, a material that's 232 times more conductive. In fact, aluminum transfers heat so effectively that it enables Warmboard to achieve the target temperature with less energy than would be required by any other system. In fact, with Warmboard, you save 10 to 20 percent on top of what you'd already be saving simply by having chosen hydronic radiant heating in the first place!
