Over the years, hydronic (hot water) heating has been used in the best comfort systems in a wide range of new and traditional homes. Hydronic heating is a method of heating that uses hot water or steam instead of air. With hydronic heat, you get two types of heat delivery: radiant heat and convected heat. Radiant heat warms you directly, just like the sun's rays. Convected heat is carried by warm air circulating in a room.
Hydronic heat lets you choose from several different devices that use these two heating processes. Hot water from a boiler can be piped to radiant tubing hidden in the floor, to slim baseboard radiators, or to stand-alone radiators. Hot water can also be circulated through a coil in your central air conditioning unit to heat other living spaces with warm air. Plus, hydronic heating produces more hot water for cooking, washing, hot tubs, swimming pools, and even radiant sidewalks and driveways to melt ice and snow.
