We have a Worcester 28 CDI combi boiler. When hot water is on it very quickly goes cold. Have noticed that the hot water indicator light does not light up every time the hot water taps/shower are turned on. Can anyone tell me what the problem is? Is it a pressure issue?
Basically it appears to be intermittent. We can have a hot (almost scalding) shower in the morning which goes extremely cold but it seems better in the evening. Either that or we're going mad!
Any feedback appreciated.
