How to bleed a radiator with a combi boiler | Trad

Boiler pump is set too high 'Cavitation' is a situation where the pump is working too fast for the water to escape the boiler. The water and air is then separated and hydrogen is created. The hydrogen will then travel round your system and escape out of the automatic air vent. This can then cause the pressure in your system to drop.

high combi boiler pressure - GasBoilerForums.c

2016-8-1 · The plumber has either put too much water in when he filled it up with water, there may be a flat expansion vessel on the boiler, or he may have uncovered a fault with the filling taps not shutting off correctly. There is a valve on the boiler that will dump excess pressure automatically if needed.

Boiler pressure much too high | Overclockers UK Foru

2007-1-2 · My heatline s24 combination boiler pressure has suddenly seemed to go through the roof and is now very close to being in the red. It's on about 2.8bar and should be in between 1 and 2. Before, when the pressure fell too low, i managed to increase it by turning a screw underneath the boiler (temporary filling loop i think), and then turning it back.
