Vaillant boiler pressure - Plumbing job in Kilburn, North London

Job description

Our Vaillant eco plus boiler last night had an error code F-22. Looking at internet forums this appears to be a problem with the water pressure. Having played with the on/off taps this morning, the boiler is working but when it is switched on the pressure on the boiler increases to the the 'red' zone

Greg arrived promptly, resolved the problem, and tested all the radiators. He was unable to explain why on/off switch on boiler wasn't working but allowed the heating to be used through the thermostat. Would recommend
