Hot water circulator

A recirculation pump reduces undue stress on the tank caused by the thermo shock of new cold water entering the system, by tempering this new water with the returning warm water.

Recirculation decreases the amount of cold water that enters the system, and that results in much less condensation and less thermal stress on the tank. A re-circulating pump brings instant hot water to any room in the house there are two types of re-circulating systems, closed systems and open ones. A closed system is like that found in a hot water heating system, where radiant heat from the water is used to heat the home. The system is always full and water is neither added nor removed. As a result, the quality of this water deteriorates to the point where it is not safe for drinking. An open system, on the other hand, allows both the inflow and outflow of water during the re-circulating process.
