Hot Water Recirculation Pumps
Hot Water Recirculation Pumps
Every homeowner gets frustrated waiting for hot water — but how many stop to think what happens to the 2-3 gallons of water that runs down the drain during the wait? Those gallons of water are wasted, and in an average household that takes four showers per day, that can add up to thousands of gallons per year.
In typical plumbing, water flows from the water heater through the pipes to the tap. Once the tap is shut off, the water remaining in the pipes cools — hence the familiar wait for hot water the next time the tap is opened.
In a region where water conservation issues are becoming critically important, Hot Water Recirculation (HWR) pumps — such as those manufactured by Grundfos Pumps Corporation — are a good solution to this problem.
The Grundfos Comfort System is a pump and valve combination that delivers you hot water in an instant to any faucet or bath in your home. The Comfort System uses a pump at your water heater along with the patented under sink valve beneath the sink furthest away from the pump. This patented combination creates a pressure differential that allows the cold and cool water in the hot water supply line to “by-pass” (at low volume) into the cold supply line through a thermostatically controlled valve that is mounted under the sink furthest from the water heater.
This combination works together to keep the water in your hot water line at temperature to provide “no-wait” hot water throughout your home. The timer on the pump makes it more efficient during downtime, like nights or mid-day. It’s quiet, maintenance-free, and keeps your water at a comfortable temperature.
