Quicker Hot Water With a Hot Water Recirculating System

29/5/2021 · When the water arriving through the hot water pipe reaches the desired temperature, the pump shuts off, and the hot water runs out the faucet rather than looping back through the cold water pipes. This is a very efficient system because when the hot water is sensed at the pump, it automatically shuts off and stops pushing the water from the hot line into the cold side.

Plate heat exchanger - Wikipedia

The small plate heat exchanger has made a great impact in domestic heating and hot-water. Larger commercial versions use gaskets between the plates, whereas smaller versions tend to be brazed. The concept behind a heat exchanger is the use of pipes or other containment vessels to heat or cool one fluid by transferring heat between it and another fluid.
