What is the purpose of a recirculation pump?
The purpose of a recirculation pump is to get hot water to all faucets within about 5 seconds. The recirculation pump is attached to a secondary supply line that is connected to the hot water supply line at the farthest fixture away from the water heater. The recirculation pump circulates the hot water throughout the entire building. This ensures every fixture has hot water within about 5 seconds of opening the faucet. A recirculation pump and recirculation line can save you money on your energy bill because the pipes are constantly hot and you have warm water returning to the water heater. Timers on the pump can save you even more money.
