| A hot  water unit equipped with a hot water re circulating pump will maintain a more  consistent level of heated water to be used through their home. So take  precautions when installing your re circulating pump.
 When  installing the re circulating pump in your hot water system you do not have to  consider insulating. The pump system works much better without insulation. The  problem with this, though, is that if it is not insulated then the water heater  will cycle between on and off more often. This occurs because the hot water  that would normally be insulated in the hot water tank is instead in the tubes  where there is no insulation to retain the heat. Circulating the water out of  the tank causes more cool water to come in. Because of this, you must ensure  that the hot water lines coming from the water heater are insulated to help the  process from working more efficiently.
