Thermostatic valves are not recommended in these cases

Thermostatic valve can keep the water temperature stable and provide a good bathing experience. And the valve does not need electricity, very safe. But not all bathrooms can use thermostatic valves. 

Today, I’d like to share with you a few cases where thermostatic valves can’t be used.

First, there is a small pump on the pipe.

If there is a pump on the pipeline, (generally, it is a relatively small pump, which is directly connected to the pipeline. There are only manual and automatic modes for this kind of pump.) Then it must be noted that after installation, open the valve to drain water. 

Pay attention to observe whether the pump starts and stops alternately in the process of valve water discharge.

If the pump is constantly starting and stopping, it can not be used with thermostatic valve in this case.

The reason is very simple, because the thermostatic valve itself does not use electricity, it depends on the temperature probe inside the valve to expand and contract, control the water inflow of cold and hot water, to maintain the stability of water temperature.

We assume that the water pump is in the hot water pipe, and the thermostatic valve will automatically move the piston to the hot water end when it senses that the hot water pressure is high and there is more water in, so as to reduce the water inflow of hot water.

The action to reduce the hot water inflow will make the water flow control switch of the water pump think that the hot water has been stopped.

Then the water pump will stop working and the pressure of the hot water pipe will decrease instantly.

When the pressure of hot water pipe decreases and the water volume decreases, the thermostatic valve will detect the decrease of hot water.

And the piston will be far away from the hot water end, increasing the excess water flow of hot water channel.

At this time, the water pump starts again.

In this way, the water pump continuously starts and stops alternately, causing pressure instability on the whole pipeline. The water output of thermostatic valve will also fluctuate, and the temperature is unstable, so it can’t be used.

Second, the hot water heater should be treated with caution

This situation is similar to the first one, except that the water flow control switch is not on the water pump, but on the water heater.

Gas water heater, hot electric water heater, will trigger the water flow control switch inside the water heater when the water is out of date. 

This is in conflict with the temperature control of thermostatic valve.

In general, the water heater may turn off or not heat during the use of thermostatic valve. No matter how many degrees the thermostatic valve is set, all the valves are cold water.

However, it should be noted that the water heater can not be used with thermostatic valve. It also depends on the local water pressure and water heater specifications. 

There are also many gas water heaters have been used with thermostatic valves, the effect is also very good. But there is a possibility that it can’t match. I hope you will pay attention to it.

In addition, if it is found that the gas water heater can not work, do not heat. We can try to set the temperature of the gas heater lower and the water flow of the heater higher. The temperature of thermostatic valve should be adjusted higher. 

There are many users through this method to solve the gas water heater does not heat the temperature, you can try.

Finally, if you have any questions or good suggestions about thermostatic valve, please feel free to contact us. Thank you for your attention, thank you.
