How is hydronic distribution of heat accomplished?

Hydronic distribution of heat is accomplished by pumping water through a system of piping that delivers heat to radiators or baseboard heaters. In this method, water is heated in a boiler, and then it is circulated through pipes to various heating units throughout a building. As the hot water flows through the radiators or baseboard units, it transfers heat to the surrounding area, warming the space effectively. This system is known for its efficiency, as water has excellent thermal properties and can carry a large amount of heat.

Using water instead of air for heat distribution minimizes energy loss and can provide a more consistent and comfortable heat, as water retains heat longer than air. The use of water also allows for systems like radiant floor heating or hydronic baseboard systems, which can offer improved comfort levels compared to traditional forced-air systems.
