Hot Water Loop Circulation Pump
It has 3 4 inch pipe thread connectors and you place it in the hot water line next to the water heater or near the fixture that needs the hot water.
Hot water loop circulation pump. This pump be placed over the boiler will circulate the hot water from the tank to your faucet. This is the cooler side of the loop or the return. At each fixture a short pipe connects the loop to the hot water valve. The pumps circulate water at low pressure and low speeds.
These pumps are often located near the water heater however they can be anywhere in the loop. However doing so in a way that doesn t waste a lot of energy is a little trickier. Once again there s no need to have lots of water moving through the loop. Now that doesn t mean that you ll have hot water circulating 24 hours a day through that line.
In this sense it will float on the cooler water. If the hot water is not used it simply returns back to the tank. A recirculating pump installed in the plumbing lines creates a loop that slowly and constantly circulates the water in the hot water pipes back into the water heater for reheating. It is just important that the water is hot near the fixtures.
A continuously operating pump is clearly wasteful. A timer activates the unit when hot water is most often needed to help you save money and water. Hot water is less dense than cold water making it more buoyant. This means that as soon as you open a faucet or turn on a shower warm water is already present in those pipes so you don t need to waste water down the draining waiting for the water to heat up.
The hot water pipe is installed in a loop throughout the home passing near each plumbing fixture. The pump runs on 120 vac power and plugs into a standard outlet. This can become an endless loop driven by the hot water in your water heater. A hot water loop uses a small pump to circulate hot water between a water heater and a distant bathroom or kitchen.
The circulation pump for this system is mounted on a pipe connected to the water heater tank down low. It will displace cooler water which then sinks because it is denser. The recirculating pump keeps hot water moving through your home s hot water pipes at all times on demand or set for specific hours via a timer different from a water heater timer. At the furthest point from the boiler you ll need a dedicated hot water line that runs back to the tank creating a perfect hot water loop.
