Water Heater Thermostatic Mixing Valve

A:  This valved is typically used on a water heater to reduce and/or limit the temperature going to the fixtures. It is installed at the heater (normally on the top); The Hot output from the heater goes to the H (Hot) input on the valve, and it is also fed with a cold line (Tee into the cold water line feeding the tank) which goes to the C (Cold input on the valve). The MIX output goes to the line feeding the property supplying tempered water to the fixtures.

A:  This is a mixing valve. The knob is the temperature controller. The opposite end is the final temperature that goes to the house. 2 sides are for cold and hot water supply from the water heater But don’t buy Honeywell mine failed in a year.

A:  After the water heater and before the showers or sinks. The valve has a "cold in" and a "hot in" and a "mix out" flow. As the name suggests the valve mixes hot and cold water to a temperature that is set with the adjustment somewhere between the extremes of the hot and the cold in flows.

A:  Between the cold and hot lines off your domestic water heater

A:  It maintains the correct temperature

A:  I do not have problems with that. Mine are in line with one 60-gallon hot water heater per 2 showers in an institutional setting. I have never had complaints of temperature fluctuation. This product has worked well for my needs. If you make frequent or recurring adjustments, you need to be careful of the plastic groves in the adjustment knob. I winterize my system. So every fall and spring I'm adjusting the temperature setting to cause the valve to allow air and antifreeze to flow freely. You just need to make sure you have good contact with the grooves before making adjustments.
