  2. Identify and check the boiler pressure gauge.
  3. If it’s above 2 bars, you’ll need to reduce the pressure.
  4. Ensure the filling loop or relief valve is tightly closed.

Why does my boiler keep losing pressure?

The most common reasons for a boiler to lose pressure are: Releasing air or water from a radiator when bleeding it. A leak from the appliance or on the system most commonly from radiator valves or system components.

Can a boiler explode?

A boiler explosion is a catastrophic failure of a boiler. There are two types of boiler explosions. One type is a failure of the pressure parts of the steam and water sides. There can be many different causes, such as failure of the safety valve, corrosion of critical parts of the boiler, or low water level.

Will bleeding radiators help boiler pressure?

Yes. During the process of bleeding radiators, air is released from within them, which in turn reduces the pressure in your boiler system.
