Hot Water Recirculation Pumps

Does the cold water coming out of your taps have you playing “Taps” for your water heater? Does the size of your ecological footprint have you thinking about steps you can take toward water conservation?

If you answered "yes" to either question, we at Whitton Plumbing, Arizona's premier plumbing company, would like you to know about the Grundfos® hot water recirculation systems we proudly stock and install.

A Grundfos hot water recirculation system ensures that you never have to wait for hot water again. 60 seconds is the time it takes in most homes for hot water to reach their faucets. But a hot water recirculation system cuts this time down to zero by providing a continuous flow of hot water in the hot water supply line of your home. Homes without hot water recirculation systems waste gallons of water every day because unused hot water in the supply line must be evacuated in order for hot water to reach the tap. The problem of waste associated with this inefficiency has grown so acute that many countries around the world have mandated that hot water return lines be included in all newly constructed homes.

Hot water recirculation systems installed in new and existing homes take two forms:

1) New construction requires a return line. This means that when a new home is constructed a dedicated return line is installed between the end of the hot water supply line and the water heater. A circulator pump is installed at the point where the return line connects to the hot water tank. This circulator pump then pushes heated water from the tank through the supply line and back through the return line.

2) Existing homes require retrofitting with a system that uses the cold water supply line as the "return-line" to the water heater. A circulator pump creates a pressure differential that allows cold and cool water in the hot water supply line to by-pass at low volume into the cold supply line through a patented thermostatically controlled valve mounted under the sink furthest from the water heater.

GRUNDFOS CAN MEET YOUR NEEDS

Whatever your hot water recirculation needs, a Grundfos hot water recirculation pump offers the solution. Grundfos has developed several circulator pump models to meet the needs of domestic hot water systems. You can choose between bronze and stainless steel models, both of which resist the corrosive effects of hot water.

Both models of the Grundfos Comfort system feature the following additional benefits:

  • Built in timer and thermostat that ensures optimum operation
  • Brass pump housing with integrated valve
  • Energy efficiency (the Grundfos Comfort system uses less power than a 25 watt light bulb)
  • Water conservation (the Grundfos comfort system saves thousands of gallons of water a year per household)

HOW IT WORKS

The Grundfos Comfort system circulates water back to the hot water storage so that it's ready the moment you turn on the tap. The pump uses the main supply line, which eliminates the need to install a return line. A small circulation pump is installed on the outlet pipe of the hot water storage tank to ensure the water in your line stays hot. The valve at your tap provides the by-pass that allows the water to recirculate using the already installed cold water pipe line as a return line to the hot water service. When the water temperature reaches 100.4 degrees F the valve will close to stop the circulation. Together the pump and valve provide instant hot water from every tap and shower in the home. And there is even a timer on the pump to make the system even more efficient during low-demand periods like night and midday.

More than 100,000 Grundfos Comfort System pumps have been installed in the United States. Contact Whitton Plumbing, your Grundfos Comfort System specialists, to join the thousands of satisfied customers currently reaping this system’s benefits.
