After installing the heat meter, how to open and close the inlet valve and outlet valve to save money? Is the water inlet valve larger and the water outlet valve smaller to save money?

After installing the heat meter, if you charge by the meter, you can save money by lowering the inlet valve and outlet valve. According to the principle of water continuity, the flow through the inlet valve and the outlet valve is the same. But under the premise that your indoor temperature is enough, turning down any valve will reduce the flow, which will also reduce the heat, that is, save money.

But it is more reasonable to turn down the hot water, which can reduce the pressure on your indoor heating system.
