Boilers or hydronic (hot water) heating has can provide the best comfort systems in a wide range of methods. 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.

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.
