~~~~~ The Problem ~~~~~

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 waste water system every single year (see state-by-state water consumption and costs).

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 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 comfort series pumps offer a solution to the problem.

~~~~~ The Solution ~~~~~

The Grundfos Comfort System is a pump and valve combination that delivers you hot water in an instant to any faucet or bath in your home. The Comfort System uses a pump at your water heater along with the patented under sink valve beneath the sink furthest away from the pump. This patented combination creates a pressure differential that allows the cold and cool water in the hot water supply line to “by-pass” (at low volume) into the cold supply line through a thermostatically controlled valve that is mounted under the sink furthest from the water heater.

This combination works together to keep the water in your hot water line at temperature to provide “no-wait” hot water throughout your home. The timer on the pump makes it more efficient during downtime, like nights or mid-day. It’s quiet, maintenance-free, and keeps your water at a comfortable temperature.

~~~~~Hot Water Recirculation - How It Works~~~~~

Traditional hot water recirculation is difficult, if not practically impossible to install in existing homes --- especially homes with finished basements. Other companies have responded with clunky under sink units that are cumbersome to install and difficult to find electrical power under bathroom sinks. Grundfos innovation has developed a solution specifically for the existing home market. The Comfort Series pump mounts on the hot water tank and connects to the hot water line. The Valve goes under the sink furthest from the hot water tank and connects the hot water line to the cold water line. The valve requires no electricity! While the water in the line is hot the valve stays closed. When the valve senses a temperature drop below 98 deg F the valve slowly opens allowing the pump to circulate hot water through the valve into the cold line which pushes water back into the hot water tank. NO OUTSIDE WATER NEEDED. When the valve heats back up it closes. The small amount of "luke warm" water in the cold line cools VERY quickly. That is how the water stays INSTANTLY HOT. The sink & shower will always be HOT right away.

No more waiting for that hot shower!

NOTE: Due to the low flow rate used by the under-the-sink squeeze valve, this System DOES NOT work with Tankless Hot Water Heaters. It simply does not move enough volume to fire a tankelss heater.

~~~~~ It Saves You Money!!! ~~~~~

Water down the drain costs you in sewer fees and you would have to pay for outside replacement water. This pump system solves that problem and saves you on your water bill and on your sewage bill. Since you are recirculating your existing water you need not buy more water and there are no losses down the drain!!! It is estimated that the average family of uses the shower 4 times per day. That adds up to THOUSANDS of gallons of water a year wasted down the drain waiting for the water to heat up.

~~~ Hot Water Recirculation Special Features ~~~

The ultimate in convenience having hot water instantly available at sinks, appliances and bathroom faucets. The elimination of time spent waiting is especially convenient in areas where the installation of low flow showerheads and faucets is required by law.

Improves the operating efficiency and effectiveness of household appliances including washing machines and dishwashers by having hot water available instantly, eliminating the lag time from the water heater to the appliance.

Users can save energy by setting the 24 hour, 3 position, 15 minute interval programmable timer to produce hot water during peak demand times such as early morning and in the evening.

The recirculation pump can typically be installed in less than one hour.

A wet rotor design for whisper-quiet and maintenance free operation.

No Electricity Needed Under the Sink.

A low-watt, two-pole motor combined with low flow performance ensures minimum water heater operating costs, pipe and water heater wear and energy consumption. Pump uses less energy than a 25 watt light bulb.

Pump is fitted with a 10 foot power cord, 115 volt with a 3-prong plug to fit a standard household outlet.

Significant water (and sewer) disposal savings, retaining the 12,000 – 38,000 gallons of water a typical U.S. home wastes annually waiting for hot water. Some fast-growing counties are making the installation of hot water recirculation pumps mandatory for all new construction projects.
