The working principle of a thermostatic faucet is similar to that of a thermostatic showerhead. Both have a valve core that contains a temperature sensing element. This temperature sensing element is made of paraffin or nickel-titanium alloy. It changes shape according to temperature variations, such as the component made of paraffin. When the water temperature changes, the volume of the paraffin also changes. Then, by adjusting the valve core ratio through the control shaft, the water temperature can be regulated to maintain a certain temperature, achieving a constant temperature output.
The valve core of a thermostatic faucet is very precise, so the prerequisite is good water quality, as poor water quality can affect the sensitivity of the valve core. When purchasing a thermostatic faucet, it usually comes with two filters, which are installed inside the inlet nut to filter out impurities.
The function of a thermostatic faucet is to maintain a constant outlet temperature; it does not display the water temperature or specify the size of the water temperature. The scale on the faucet's handwheel can only be an approximate value, which is not accurate. Generally, thermostatic faucets have overheating protection around 38°. If you want to increase the water temperature, you must press the increase button to turn the handwheel.
