Why does the boiler always have to be filled with water?

Phenomena: The displayed value of the pressure gauge drops frequently. \x0d\The normal boiler water pressure should be above 0.8 bar, and the water replenishment cycle lasts about 3-6 months or more. \x0d\The boiler is connected to the heat dissipation system of the room to form a heating system. The water pressure gauge on the boiler shows the pressure value of the entire heating system, so water replenishment concerns the entire heating system. Therefore, in most cases, frequent refilling is a possible problem with the heating system and not the boiler. \x0d\Reason 1: Newly debugged heating system\x0d\At the start of the newly debugged heating system, there was a lot of air in the system. Releasing the system's automatic exhaust valve caused a drop in pressure, requiring multiple water refills. \x0d\\x0d\Reason 2: There is aleak in heating system\x0d\ There may be loose sealing and leakage at the interface of exposed pipes or underground pipes of the heating system, and the amount of leakage is not large since. The boiler is in heating state, the whole system is hot, so the leaking water evaporates quickly, making the leak difficult to detect with the naked eye. \x0d\If the boiler is losing pressure and the leak cannot be detected, it is recommended to first check the boiler for leaks. \x0d\Inspection method:\x0d\Stop operating the boiler, close the heating water supply tap and return tap under the boiler (make sure the tap can be closed tightly), unplug directly the system boiler, add water to the boiler for a whole value and observe the water for a while. Is the pressure gauge still fluctuating? This method makes it easy to determinet if it is a problem with the boiler or a leak in the heating system pipe behind the valve. \x0d\\x0d\Reason 3: Failure of the expansion water tank in the boiler\x0d\ Failure of the expansion water tank will cause the system pressure to exceed 3 bar when the boiler heats up and the valve security will leak for protection reasons. Please contact your agent for replacement. \x0d\Reason 4: The water replenishment valve is not closed tightly.\x0d\\x0d\If the water replenishment valve is not closed tightly and the water pipe network pressure of the faucet is weak, the system will lose pressure when using domestic hot water. \x0d\\x0d\Solution: In case of frequent water replenishment, you should contact the after-sales service provider to check the heating system as soon as possible to avoid damage to the heatingcaused by long-term water replenishment.
