This water heater system comes with a Watts 800500 Premier Hot Water Re-Circulating Pump:

– Uses less energy than a 25 watt light bulb

– Includes a programmable timer that can be set to activate the pump only when you need it or set it to run 24-hours a day

– This device uses the pump at the water heater and a patented under-sink sensor valve to create a pressure differential. The pressure differential allows the cold and cool water in the hot water supply line to bypass into the cold water supply line at a low volume through the thermostatically controlled sensor valve, keeping the water in the hot water supply line at a “no-wait” temperature throughout the home.

– Thermal By-Pass Technology

– Saves up to 12,000 gallons per year

– Maintenance Free

– This system is not designed for tankless water heaters

When is Liftgate Service Necessary?

Most of our carriers' trucks are not equipped with a liftgate. To guarantee a liftgate delivery when you order from us, you will want to select the Liftgate Service option at check out.

A liftgate is a hydraulic lift on the back of a truck that lowers freight from the truck to the curb or street. It is important to have if you do not have a way to get the equipment off the truck yourself.

If you’re not sure whether you need Liftgate Service, contact us! If you don’t request Liftgate Service and your delivery is unable to be moved off the truck, the carrier may charge you a re-delivery fee, in addition to the Liftgate Fee.
