Hi guys,
First time posting on the forum and could do with a little help please.
We have a Worcester 28CDI combi boiler and over the last few weeks the pressure has been rising by itself to about 3 bar then lowering a little, then back up to 3 bar and so on. I released some pressure out so that it was back down to about 1.5 bar but then it steadily crept up again.
So i started searching through the forum for answers and it seems that the this would suggest that the water to water heat exchanger needs replacing. Could anybody confirm these symptoms suggest that please?
Also while searching for info and prices of the part over the last week i noticed that the pressure had dropped to 0.8 bar. So i refilled to 1.5 and then it seemed to hold steady over the next few hours which puzzled me somewhat. Then as leaving the house that day i noticed the overflow pipe outside was dripping water out. So it seems that the Pressure relief valve is letting pressure out at whatever pressure the system seems to be at.
Would this suggest that the Pressure Relief Valve has become faulty after venting the built up pressure for a week or so?
Any Advice appreciated guys.
Thanks, Phil.
