Hot Water Recirculation
The Basic Concept
Every homeowner gets frustrated waiting for hot water --
but how many stop to think what happens to the 2-3 gallons of water that runs
down the drain during the wait?
Those gallons of water are wasted, and in an average
household that takes four showers per day, that can add up to thousands of
gallons per year. Multiplied over a subdivision of 300 homes, a community can
have millions of gallons of water go down the drain and into the wastewater
system every single year.
In a region where water conservation issues are rising in
importance with a rapidly expanding population, and a record economic expansion
that has consumers looking for comfort, Hot Water Recirculation (HWR) pumps --
such as those manufactured by Grundfos Pumps Corporation -- are a good solution
to this problem.
In typical plumbing, water is pumped from the water heater
through the pipes to the tap. Once the tap is shut off, the water remaining in
the pipes cools -- hence the familiar wait for hot water the next time the tap
is opened.
Grundfos HWR pumps offer a solution to the problem by
attaching to the water heater through the hot water pipe. By constantly
circulating hot water through the pipes from the heater to the furthest fixture,
the water in the pipes is always hot, and no water is wasted during the wait. In
an average new home, HWR systems typically cost less than $1,000, including
parts and installation.
