What is hot water circulation system?

A hot water recirculation system is a plumbing system that moves hot water to fixtures quickly without waiting for the water to get hot. Rather than relying on low water pressure, common in most water lines, recirculating systems rapidly move water from a water heater to the fixtures.

How does a hot water circulation system work?

This system creates a loop from the water heater to the faucet and back again. The unused hot water is drawn back through this loop by the pump, so when you turn on your hot water faucets, you get hot water quickly. Water is not left in the pipes to get cold and you waste less water because you don’t have to wait.

Will hot water circulate without a pump?

Joseph Stoddard responds: In the situation you describe, you can get acceptable results without a pump. The hot water “passive recirculation” loop is a technique I learned from an old plumber years ago. By providing a return piping run to the hot-water tank, a natural circulation (called a thermosiphon) is created.

Are hot water recirculation systems efficient?

For homeowners whose biggest concern is keeping their energy bills low, hot water recirculation systems are not the best choice. Even the most energy efficient options will raise your electric or gas bills, and the money you save on your water bill is unlikely to make up for the increased costs.

Do circulator pumps run all the time?

So depending on where you live and how your heating system is designed and controlled, it may be normal for the circulator pump(s) to run continuously.

How can I tell if my circulator pump is working?

One way to detect a problem with the circulator pump is to check the radiators and tubing coming from the pump itself. As the thermostat tells the pump to circulate the heated, or cooled air, check the tubes to see if they warm up or cool down. Touch the radiator tubes to check if they are getting hotter.

What saves water by keeping lines with hot water?

Recirculation saves the many gallons of water that are wasted running faucets for hot water, and hydronic heating circulates the same water over and over again.

Can I turn off my hot water recirculating pump?

Yes, you can turn off your hot water recirculating pump. Solutions like- unplugging it, using a timer and using wifi sockets are convenient. Make sure to follow the required instructions before and after you’ve turned it off for your safety.

Should my circulator pump be hot?

Feel the Hot Water Heat Piping at the Circulator Pump The most common way to see if the circulator pump is having issues is to touch it. It doesn’t matter which side you feel; it should be warm or slightly hot when running.

Where can I buy a hot water recirculation system?

Hot water recirculation systems are available nationwide from manufacturers, distributors, plumbing wholesale supply warehouses, and at selected retail home stores. The initial cost of dedicated systems may prevent some homeowners from installing these systems, as they require the purchase and installation of a pump and a large amount of piping.

How does a closed loop hot water circulator work?

Hot Water Circulation System (highest install cost, highest operating cost, greatest hot water comfort, no influence on cold water comfort) A hot water circulation system/ closed-loop system uses a dedicatedhot water pipe which loops throughout the home beginning and ending at the water heater.

How much water is wasted by hot water heaters?

They conserve water. According to statistics from the U.S. Department of Energy and the U.S. Census Bureau, between 400 billion and 1.3 trillion gallons of water (or close to 2 million Olympic-sized swimming pools) are wasted nationally by households per year while waiting for water to heat up. They limit municipal energy waste.

How does a readytemp hot water circulator work?

ReadyTemp systems prevent hot water line siphoning during cold water use by incorporating a hot water solenoid valve and our Intelli-Circ controller. Thus, eliminating the reoccurring costly demand placed on water heaters by competitor systems with inadequate flow control.
