Are you tired of waiting for hot water to reach your shower every day? Do you shake your head as wasted cold water flows down the drain? SupplyHouse may have the solution: a hot water recirculation pump. These pumps allow you to get instant hot water at the turn of the faucet and can result in big savings on your water bill. When you turn off a shower or faucet, the water sitting in the pipes gradually loses its warmth through a process known as standby loss. This is the first water released for the next usage. Recirculation pumps cycle this water back to the water heater to ensure you get hot water right away.
Circulator pumps with high head and low flow rates (a Taco 009, for example) work for this type of application. But if you’re looking for a product designed specifically for the job, SupplyHouse recommends a Grundfos Comfort Series Hot Water Recirculation Pump. These pumps include a timer that forces water back to the heater through the cold water line at set times. This easy-to-install product uses less energy than a 25-watt light bulb, and can save up to 16,000 gallons of water per year.
