Hot Water Recirculation
Studies show a family can save anywhere from $100 to $250 a year by adding hot water recirculation. Hot water recirc is also an environmentally friendly thing we can do to save water. Hot water recirc systems can easily be installed at new construction but there are also retrofit solutions.
Abacus has had a great track record using Grundfos pumps for heating and cooling solutions. They are also the people to go to for hot water recirculation. They are the most reliable and available pump in the world and there are reasons for it. They manufacture with the highest standards for functionality, reliability and control.

Hot Water Recirculation Payback Calculation
A common homeowner complaint is the long wait for hot water in the bathroom. Frequently, that wait can last for one or two minutes. Toss in a family with several bathrooms, and the potential exists for large volumes of water to be wasted. Our chart with the calculation based on pipe size, length of run, and daily usage indicates 9,855 to 55,115 gallons of wasted water per year. www.grundfos.us/hwr
Hot water recirculation system applications:
- 24/7/365 constant circulation with a dedicated return line
- Dedicated return line with an aquastat to turn the pump on and off
- Dedicated return line with timed pump circulation
- Hot-to-cold timed circulation with an aquastat to limit the cold water line’s temperature
- Thermal by-pass systems can be motion-sensor, infrared, or manually activated
Why is it important?
Water use:
- An average home over 2,000 square feet has 125 feet of ¾-inch pipe
- 125 feet of ¾-inch Type L copper pipe holds 3.14 gallons of water
- 10 draws per day wastes about 31.4 gallons of water
- Over a year, the use equals 11,461 gallons
- 25.2 million homes waste 288,817,200,000 gallons of water per year
Wasted water cost analysis:
- Assume 12,000 gallons water wasted per year
- At $.007 per gallon, that comes to $84 down the drain
- At 82% efficiency, heating water to 55 degrees F to 140 degrees F costs $138.33 (natural gas costs $.01335 per 1 cu. Ft.)
- Add yearly sewage treatment cost of $52.79
- The total wasted-water-cost would come to $275.12
The system’s initial cost and fees to install an electrical outlet may seem like a deal-killer. But if you promote the return on investment, your sales will increase. ROI is calculated by dividing the system’s cost into the annual fuel savings. If you project an annual saving of $100 and the system costs $600 installed, the ROI is an attractive 16.7%, which is also a tax-free ROI.
