Heating ok but no hot water

[donmaico]

I have a 5 year old Alpha CB 28 boiler on which I suspect the heat exchanger needs replacing plus a flush is required .Now I took out a contract with Homeserve after I discovered the problem over the weekend who are promoted by Alpha as the company to deal with post warranty repairs.One of their engineers is due to see me today but what is concerning me is that they told me that a replacement heat exchanger is not covered and in such situations they recommend a new boiler.Now I know I have had to have this part replaced twice with this boiler and in neither of the two occasions was a new boiler suggested.I feel very much inclined to cancel this visit and try a local fitter instead.Could you please advise me on this ? So far i have paid £300 which includes a years cover plus a one off repair consisting of one part(not heat exchanger tho)

well thats done then! Turned out to be the flow switch after all.
H. E. didnt rate Apollo boilers much , reckoned Valiants to be about the best🙂

Had further problems with a leak .Homeserver refuse to cover it stating the water had too much sludge in it and was quoted £50 per rad to clear(10 rads = £500) the system.Eventually got in touch with a local plumber who added some Sentinel x400 , the system was left running for three weeks then he returend to empty it and added another chemical x100 sentinel inhibitor.All for about £120 which struck me as reasonable
Alpha engineer came and repaired the leak although there is still a slight one so i must get him back
I am wondering now whether to have a;ll existing stainless steel pipework replaced and a magnaclean fitted
I'll not use Homeserve again that is for certain.They are way too slow in responding and the engineering company they use dont seem to buy from local sources meaning further delays.
