Worcester Bosch Boiler

Hi,

The Pressure gauge of my Worcester Greenstar 30CDi boiler has slowly crept into a red zone. I have a pressure release key; however, I am unable to find the connector under my boiler. Can someone advise me regarding the target pressure? Secondly, the towel bar does not heat up properly. What should I do?

Many thanks

Tom

Hi Tom,

Firstly, I would advise you to bleed the towel bar radiator. It will have an effect of decreasing the boiler pressure & expectantly allowing it to work properly. Afterwards reduce the pressure of your boiler by simply draining off at a suitable rad as it is a very boiler friendly way. You have to keep it up until reaching 1-1.5 bar. However, if the boiler pressure increases after doing so & keeps climbing then, suspect either a filling loop is not shut off completely or possibly the heat exchanger problem.
