Help: Is it normal for the pressure difference between the hot water inlet and outlet in the device area to be 1 kilogram? Thank you for the helpful advice.

Are there flow meters to measure inflow and outflow? Is there a leak?

I think it’s normal; since the diameter of the heating tubes is usually very small, such as those used in instrument tubes, the outer diameter of the heating tubes in some instrument cabinets can be 10 mm. Moreover, when several instruments are connected in series and then return to the return pipe, the system resistance becomes quite high. This has happened in our equipment as well: when the backflow pressure is high, the heating pipeline cannot flow back, causing the instrument to freeze.

Is there a design issue causing this, such as an incorrect selection of the pump for the hot water supply system?
