You save water.All that water spend waiting for the hot water to finally kick in is not wasted anymore. In the brochure for Watt hot water recirculation pump, you might see something like‘Watt circulation pump can save you up to 12,000 gallons of water per year’. That would be about ...
Laing’s flagship water recirculation pump. Unlike many models, this unit is installed under the sink or faucet farthest from the water heater. This is the most simple type of recirculator to install. A bit more expensive than the Watts unit above, but well worth the premium if you want ...
Thanks, Sean. So a crossover is just where a demand recirculation pump pulls hot water and dumps it into the cold line. I’m familiar with how it works but don’t think I had run across that term. My current plan for the new plumbing system I’m going to put in next year (not ...
No pump power or heating fuel used when building is unoccupied. Hot water boiler is correctly sized & insulated to an economic thickness calculated using local criteria.Located to meet demand for hot water. All pipework in both unheated & heated spaces is well insulated & insulation feels cool...
The risk is quite low considering all the safety devices installed on the plumbing, for example: temperature controllers on the heat source and on the distribution network, recirculation pumps and mixing valves used to add cold water along both pipes and at the point of use. Temperature at the...
The water is kept hot by recirculation through a heat exchanger 2 that is an integral part of the compressor. The storage device may have a variable volume 11 so that when a quantity of hot water is used it is not diluted by cold water entering the device. Cold water is heated before ...
Close the water supply valve to the unit. (You can turn off the recirculation pump at this stage if your model has one). Turn the hot water on at the faucet closest to the water heater. Turn the hot water faucet on at the furthest sink from the heater as well. ...
Water recirculation lines, if not installed properly, can cause many problems. If the circulation line is sized too small the water travels too fast making noise and wearing the pipe out prematurely. The slab leaks, leak under concrete, are primarily on hot water recirculation lines. If the li...

Fireman switchA device ensuring that the heater shuts off for a period of time - say, five to 15 minutes before the recirculation pump shuts off. This switch allows the water to cool off the system before it stops running, thus prolonging the life of the heat exchanger. (Due to varying ...
