![]() No one manufacturer supplies all the components for hydronic radiant heating. In general, expect to pay 50 percent more for a hydronic radiant flooring system than for conventional forced-air heat. $6 to $15 a square foot for installation. Unlike copper, this inert plastic won’t corrode and can be installed in long runs with just a couple of fittings, reducing the chance of leaks. Specially treated polyethylene carries the hot water for hydronic systems. Slowly raises and lowers the amount of hot water flowing through the tubing in response to changing outside temperatures. Multiple heating zones: Makes it easy to fine-tune the amount of heat being delivered to different rooms. Why You’d Want OneĮliminates forever the discomfort of cold floors as it slashes energy bills. Heated water is pumped from a boiler through a loop of flexible tubing embedded in the floor. Hydronic Radiant Floor HeatingĪn energy efficient home heating system that turns entire floors into radiators, warming living spaces without uncomfortable hot or cold air pockets. In that category, radiant always wins, feet down. And there’s no comparison when it comes to comfort. And you’ll still need a separate air-conditioning system for cooling.īut if the price tag puts you off, consider this: Once it’s up and running, a radiant heat system can be up to 30 percent more energy efficient than forced-air heating, depending on how well insulated a house is. (New builds where the tubes are buried in concrete slab tend to be the least expensive). Hot-water radiant costs more to install than other types of heating systems-from $6 to $15 per square foot depending on the method, whether you’re starting from scratch or retrofitting, and where you live. “It’s like putting a sweater over a radiator.” “If the floor is too well insulated, radiant heating really doesn’t make sense,” Richard says. Once the system is in place, you can cover it with most types of finish flooring, including hardwood and tile.Ĭarpet, however, can be tricky, especially if it has thick padding underneath. The flexible tubes can be installed in a variety of ways: on top of the subfloor in grooved panels or snap-in grids clipped into aluminum strips on the underside of the floor or embedded in poured concrete.
