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.What It Costs: to a square foot for installation.You'll need a good heating contractor to put a system together.With electric radiant, it's easy to find turnkey systems.And there's no comparison when it comes to comfort. What It Is: An efficient home heating system that turns entire floors into radiators, warming living spaces without uncomfortable hot or cold air pockets.How It Works: Hot water is pumped from a boiler through a loop of flexible tubing embedded in the floor.
What To Look For: Multiple heating zones: Makes it easy to fine-tune the amount of heat being delivered to different rooms.
And you'll still need a separate air-conditioning system for cooling.
But if the price tag puts you off, consider this: Once it's up and running, a radiant system can be up to 30 percent more efficient than forced-air heating, depending on how well insulated a house is.
It's also a highly efficient way to heat a house, increasing comfort as it reduces energy costs.
In a radiant setup, the warmth is supplied by hot-water tubes or electric wires buried underneath the floor.
