What temperature should a mixing valve be set at?

These valves should never be set to exceed a maximum temperature of 49C (120F). (Watts recommends the maximum temperature of 43C (110F) for shower and bathing fixtures.)

What temperature should shower valve be set at?

Showers – Each shower will have a slightly different hot water supply temperature between 134°F and 129°F depending on where it is in the distribution system, the maximum temperature limit stop should be adjusted on all showers and tub/showers to a maximum of 110°F-115°F or as required (120°F max.)

How do you adjust a mixing valve?


You want to turn that towards the plus symbol. That's going to allow more hot water to come into the mixing valve. And then to all your faucets your shower.

Which way do you turn a mixing valve for hotter water?

automatic mixing valve clockwise makes the outgoing water temperature cooler. Turning the Watts mixing valve counterclockwise makes the outgoing water temperature hotter.

What is a hot and cold water mixing valve?

A thermostatic mixing valve (TMV) is a valve that blends hot water with cold water to ensure constant, safe shower and bath outlet temperatures, preventing scalding.

How do I make my mixing valve hotter?

Quote from the video:
Or blue part and adjust that then it gets you more hot water. So the more you adjusted counterclockwise the hotter it's gonna be as I said this up here I think it was somewhere up there before.

How do you adjust the temperature on a thermostatic mixing valve?

To adjust the temperature supply remove the plastic cap on top of the valve and adjust with a close fitting spanner. To increase the temperature turn anti-clockwise To decrease the temperature turn clockwise To set the valve to a maximum recommended mixed water temperature, see table below.

How do I adjust the wattage on my hot water mixing valve?

To adjust the setting of the valve, loosen locking cap screw with hex wrench, see Figure 2. Cap must be lifted 1/4” to adjust temper- ature. To increase the tem- perature, turn counterclockwise. To decrease temperature turn clockwise.

Do I need a mixing valve on my hot water heater?

Conclusion. Thermostatic mixing valves on your water heater are essential to prevent scalding and control water temperature at the delivery point. It allows you to increase the heater temperature, killing off harmful bacteria.

How does a 3 way mixing valve work?

Three-port mixing valves. The valve takes hot water from the boiler and mixes it with the cooler return water to provide a circulation of mixed water of sufficiently high temperature to meet the heating demand. The system operates with a constant flow rate and variable temperature.

What is the difference between a mixing valve and a thermostatic mixing valve?

Quote from the video:
In both of these thermostatic mixing valves we have thermostatic cartridges that allow for up to 12 liters per minute flow rate. This means that we can connect up to four faucets.

What is the difference between 2 way and 3 way valves?

2 way and 3 way valve classifications are commonly used in industrial applications. These valves are defined by the number of ports they use. 2 way valves, as their name suggests, consist of two ports: an inlet port “A” and an outlet port “AB.” On the other hand, 3 way valves consist of three ports: “A,” “B,” and “AB”.

What does a thermostatic mixing valve do?

The thermostatic mixing valve neutralizes both threats by allowing the water heater to be set to a high enough temperature to reduce the threat of bacteria growth, yet the mixing action maintains the appropriate outlet water temperatures to the fixtures and allows occupants to use the sinks, showers or tub with less …

How much more water do you get with a mixing valve?

By installing a mixing valve and slightly increasing the target temperature on the hot water heater, you can increase the capacity of a tank – in some cases by up to 50%.

What is the difference between a TMV and a tempering valve?

A tempering valve is accurate to around 3℃ +/-, while a thermostatic mixing valve can keep the water to 1℃ +/- and responds faster than a tempering valve to changes in incoming water temperature.
