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 (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 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. How It Works A return line is installed near the faucet farthest from the water heater. The return line is connected to the UP 15 series pump and flows back to the water heater. As water slowly cools in the hot water line, the UP 15 series recirculation pump then moves the hot water from the heater throughout the pipe back to the heater, creating a continuous loop of slow-moving warm water. When a faucet is turned on, warm water is instantly available for use with no waste. Special Features The ultimate in convenience is 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 are required by law. HWR 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 programmable timer to produce hot water during peak demand times such as early morning and in the evening. The recirculation pump can be installed by a certified contractor in two hours. For the average home, hot water recirculation systems generally cost less than $1,000, including parts and installation. A wet rotor design for whisper-quiet and maintenance-free operation. Stainless steel rotor cladding and canister construction, an exclusive UP 15 series feature, ensures corrosion-resistance and extended product durability. These circulators are available with various configurations including bronze housings with ½†and ¾†sweat and stainless steel housings with union connections. 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. Significant water (and sewer) disposal savings, retaining the 12,000 to 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.
