Why is my Vaillant boiler pressure too high?
There are three possible reasons why your boiler pressure is too high: Your external filling device is faulty (a pressure filling device not located on the appliance, usually under the appliance on the pipework) These devices may not be fully closed or could be allowing water to pass through a closed valve.
What causes high pressure on your Vaillant boiler?
Vaillant boilers, Ecotec, Ecomax, Turbomax. Losing pressure when the heating is turned on?? What causes high pressure, or the gauge to go into the red on your boiler, then low pressure afterwards and the F.22, F.20 and F.28 FAULT CODE?
When to remove filling loop from Vaillant boiler?
Yes it would gradually increase as more water enters the system. You should see it starting to leak from the overflow pipe. You may want to remove the filling loop when not using it to rule that out or get a new one as they do go bad. Sorry to bother you again, but just wanted to pick your brains a moment as a follow up to the advice you provided.
What should boiler pressure be at 3 bar?
Anything above a boiler pressure of 1.5 bar isn’t ideal. 2 bar starts to become more serious and when most boilers hit 3 bar, they’re in the red zone on the pressure gauge. So, the unit is likely to lock out and display a fault code. If this happens, I’d suggest speaking to a Gas Safe boiler engineer. Why Boiler Pressure Rises
Is it normal for boiler pressure to be too high?
Boiler pressure reading as high, only when the heating is on? A boiler pressure gauge reading over the 1.5 mark whilst the heating is in full operation, is likely normal due to the water demand being placed on the boiler so it’s likely nothing to worry about. In this instance, a reading between 1.5 – 2.5 bar can be considered normal.
