Alpha CB24 no hot water

Hi Guys,

I have a problem with an alpha boiler, model CB24. When I turn the hot tap water on boiler switch on and produce hot water but for only 1-2 minutes. If I want more hot water I need to close and open the tap again, and again and again… imagine a bath like this. I have enough… Any ideas what may be the issue. I should add that each time I open the tap boiler starts to work, but then it switches off, no lights.

Thanks

Jake

Hi Jake,

I think it will be a problem with the DHW heat exchanger, it will either need to be exchanged or you will need to check if it is not blocked by sth. I would vote for being blocked rather. If you remove the heat exchanger from the boiler and clean it a bit it can fix your problem.
