One boiler problem with the water chemistry that can happen is water leaks. Improper water chemistry inside a boiler can lead to pinhole leaks in the tank, pipes or other parts of the system. Water leaks can occur anywhere in the steam system. Look for dripping around the tank or its pipes, but leaks may also occur away from the tank.Get Price
We've covered more boiler noises in Why is My Central Heating So Noisy? to help you get to the cause of the problem. 6. Low boiler pressure. Boiler pressure is a measurement of the pressure of the hot water passing through the central heating system. Should the boiler pressure drop too low then the central heating will fail to work.Get Price
