Radiant heat is a fast-growing home heating alternative. It works by sending heated water from your boiler or water heater through a tubing system that is installed in the floors, heating your entire home. Radiant heat has many advantages over forced air conventional heating systems. It's more efficient and economical ... it eliminates the need for unattractive and noisy air vents ... and it keeps the air in your home cleaner and healthier because it does not circulate allergens and dust throughout the house.
