~~~~~ 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 pumps offer a solution to the problem.

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

Grundfos Comfort circulator pump delivers you hot water in an instant to any faucet or bath in your home. The UP10-16BU ATLC makes a hot water recirculation installation a snap. You pull the dedicated return line, the circulator does the rest!

For those unfamiliar with the connection of a timer, aquastat, isolation valve and check valve in a traditional hot water recirculation system the task can appear daunting. After installing a return line in a new home some contractors have battled a bundle of components necessary to complete the job.

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

This system requires a dedicated return-line to be installed from the end of the hot water supply line back to the water heater. A circulator pump is used to circulate water through the main hot water line and the return-line back to the water heater to keep hot water in the main line. A timer, aquastat, or both may be used to control the operation of the pump. The Grundfos UP 10-16’s, as well as the UP Bronze and Stainless model circulators are common in this application.

No more waiting for that warm shower!

~~~~~ 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 selecting the units with a built-in Aquastat and/or built-in timer. Set 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. Aquastat control monitors the water temperature in the hot water line so the pump only runs when required to ensures optimum operation.

The recirculation pump can be installed by a certified contractor in two hours. For the average home, hot water recirculation system's generally cost less than $1,000, including parts and installation.
A wet rotor design for whisper-quiet and maintenance free operation.

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.
