2020-7-20 · A single central thermostatic mixing valve is the most common installation arrangement although there are several point-of-use faucets available which feature thermostatic control. Typically though, a single unit is installed on the main outlet from the water heater which then feeds water at below 122° to manual mixer valves on baths and showers.

Hot water system temperatures and the code

2015-2-1 · The system should have a mixing valve to establish a constant hot water delivery temperature with a circulating pump sized for a 10 degree temperature difference throughout the system. If the system utilizes a bi-metal coil technology in the master mixing valve, a 20 degree temperature differential may be required for the valve to operate properly.

Recirc pump with mixing valve Thanks for the comments. My concern is not cold water intrusion but absence of cool water to add to the hot water loupe. If I return the water from the tempered loupe into the tank, the only source for replacement water supply to the mixer valve and tempered loupe would be hot water from the tank.

2015-1-20 · The mixing valve would work exactly the same with recirculation. IF the tank has a recirculation port (most don't, but a few do), you'd use that for the return line, otherwise, you usually put a T into the drain line by moving the valve out to accommodate a T there. . If you have a tempering valve on the water heater, and a recirc pump, you .

How Do Sensor Valves Work? - Hot Water Recirculators

When this path is open, the hot water heater in tandem with the hot water recirculation pump push actual hot water through the pipes. When the actual hot water reaches the valve, the metal expands again causing the path to close. Then the path/valve stays closed until the water cools down too much again, at which point the cycle repeats itself.

2020-5-13 · This special tee fitting allows the pump to pull the cooled off water in the hot water line back to the tank through the cold water line. This reduces the amount of wasted water that is poured down drain while waiting for hot water. In your case, you are going to want to install the pump on the outlet (common port) of the mixing valve.

A mixing valve performs the same function, but it does so at the water heater instead of at the faucet. Because the mixing valve is mounted at the water heater, hot water meets cold water right as it leaves the hot water tank, and less hot water is removed from the tank to achieve a desired temperature.

0.10/kwh = 7.20/month, per pump of operation. I used these numbers for easy ballpark. 0.20 kwh/month, double it. 0.15, add half, etc. Using Reset on/off control, I'd guess 75% run time. 50 watt circulator? Half it. for a typical 15-58 on a reset system it's about 5/month, per pump.

2019-4-26 · With a tempering valve and a recirc pump, you also use an aquastat which turns the pump off when the return line is at a preset temperature. Without a means of turning the pump off, the water continues to cycle through and gets as hot as the highest setting on the water heater. You can't run the pump continuously when you have a tempering valve.
