Boiler reputation - track record

[John]

My daughter's house has a Alpha Ocean 280P combi boiler.

Do these have any know 'issues' that I should be aware of?

Looking for a Corgi guy to come and give it a check / service but I don't want to be conned with that sharp intake of breath!

My perception is that these boilers are towards the lower end of the market. Spares tend to be very expensive, IME

here:

least one of the Ocean range suffers repeated water diaphragm failure but its a good regular source of income for service engineers ;-)

[Doctor Drivel]

The Ocean had a very good reputation.

IME any boiler which moves the main diverter valve using DHW flow diaphragms is inherently less reliable than those which don't. Even some top end makes do this and they also have problems.

Not the two we had in rented flats: replaced after seven years because of leaking heat exchangers (£300 to replace IIRC). The couple of Vaillants were all but trouble free over ten years.
