If you’re tired of watching water go down the drain while waiting for it to heat up, the Watts Instant Hot Water Recirculating System may be just what you need. The pump attaches to the hot water line at the water heater to circulate hot water throughout the home. A programmable timer can be set to turn the pump on only during the hours when hot water is typically used. The kit comes with everything you need and can be installed in under two hours. The Watts Recirculating Pump is available from The Home Depot for around $200.00.
