Hot Water Heating System

True hot water heat control comes with multi-zone systems, which operate as loops off of the main pipes to deliver heat to selected radiators in the home. When heat is not called for in that zone, the zone is bypassed and blocked from receiving hot water backflow by a spring-loaded check valve. This prevents unnecessary heat loss along the way and unnecessary heat gain in rooms that don't need it.

Baseboard Heat
The most common type of hot water heat in the United States is finned-tube baseboard heat. Located close to the floor, finned-tube emitters are usually housed in metal enclosures that have reflective material behind them to encourage heat transfer from the fins or slats to the air passing over them, rather than being lost via conductivity through the cold wall behind it. The hot water pipes emerge from the floor and run directly behind the enclosure with thin, metal slats or fins, placed close together all along the pipe. Heat is transferred from the water to the pipe and ultimately to each of these fins. The fins serve as multiple heat emitters, warming the cold air from below. Enclosures must be located at least one to two inches above the finished floor to allow for adequate air circulation and heat transfer
