See How It Works

Easy as 1-2-3

1. A hot water recirculating pump with a built-in pre-programmable timer is installed at the water heater.
2. A small bypass valve is mounted under the tap located farthest from the water heater.
3. The existing cold water supply line is used as the "return line" to the water heater.

WARM|FRONT™ Hot Water Starter
with Grundfos Technology
A simply smarter system.

In typical plumbing, you turn a faucet off and the unused hot water remains in the pipes and cools down. The next time the faucet is used; there is a wasteful wait for hot water to reach the tap. Not only is this inconvenient, but many gallons of water go down the drain as you wait.

The WarmFront- an easy and economical solution
By simply attaching a hot water recirculation pump to the hot water pipe that comes out of your water heater the hot water in your pipe is kept flowing...giving you instant hot water throughout your home during pre-programmed times. No wait, no waste and it's maintenance free. The pump's innovative design ensures quiet operation. The pre-programmable timer allows you to save energy by the only heating water when you need it.

Unlike more complex and expensive hot water recirculation systems,
the WARM|FRONT unique design uses your existing main supply line, eliminating the need to install a return line. A single pump is connected to the water heater and a patented bypass valve is placed at the points of use that are farthest from the water heater.
