Plumbing Circulation Pump
The average household wastes 27 to 105 gallons of water per day while waiting for hot water. A recirculation pump conserves water by providing hot water immediately - as soon as the hot water tap is turned on – and prevents the unnecessary waste of gallons of cold water down the drain while providing convenience and comfort. The
Grundfos system uses between 55 to 85 watts per hour. Energy cost will vary according to local rate but in avarage the annual cost to operate this system will be less than $20 per year and will save on your water bill.
