Grundfos Instant Hot Water System Helps Homeowners Conserve Water

19.03.2002

Hot Water Recirculation Can Save Households Thousands of Gallons of Water Annually

OLATHE, Kan., March 18 /PRNewswire/ -- Homeowners can reduce their annual

water use by thousands of gallons annually by adding a simple, low-cost hot

water recirculation (HWR) system that saves water by delivering hot water on

demand.

Grundfos Pumps Corporation, a global manufacturer of pumps, recently

introduced the Comfort Series Instant Hot Water System. In homes larger than

2,000 square feet, the Comfort System can save more than 16,000 gallons of

water per year for a family of four, as well as deliver the convenience of

instant hot water.

With traditional plumbing, hot water from the water heater is left in the

pipe after use. The water cools and must be purged the next time the tap is

opened. This wastes these two-three gallons each time there a need for hot

water. Instant hot water prevents this waste and in most markets, the pump

and valve system will cost less than $600 installed in either new or existing

homes. The system consumes about the same amount of electricity as a 25-watt

light bulb.

"During this time when so many communities are struggling to reduce water

consumption in the face of drought, recirculating hot water is an inexpensive

way for homeowners to help their communities conserve water while adding the

amenity of hot water on demand," said Hans Kircher, HVAC segment director for

Grundfos Pumps.

Grundfos, a long-time leading provider of circulator pumps for closed-loop

HWR systems installed in homes under construction, supplies the patent-pending

valve systems via plumbing wholesalers nationwide.

"This retrofit system is installed with a single pump at the water heater

and a valve at each branch of the plumbing out to the fixtures," Kircher

added. "It provides the same water savings and comfort as a closed loop

system and has a more straightforward installation than any competing under-

the-sink system."

Various competing retrofit HWR systems require multiple pumps, electrical

installations at each sink, and often still require a wait for hot water at

the tap, even if the water is delivered hot.

Ownership and installation features include:

Ownership features:

-- Water and Energy Conservation: saves as much as 16,000 gallons of water

per year per household (average usage)

controls

-- Cost Savings: reduces water utility costs and related charges

-- Whisper Quiet Operation: no extra noises from the basement from the

-- No Return Line Required: reduces parts and labor costs
