Is a Hot Water Recirculating Pump Worth It? The Pros and Cons

Mar 11, 2019 · If you shut the heater off then the recirculating pump will only be able to circulate the water whatever temperature it may be. How long that stays hot is dependent on your tank. As you said it is insulated so it should stay hot for a few hours I would think. Though, with the water circulating it will cool faster than if it is in the tank.
