[Help] Any Plumbers? Intermittent Hot Water

[Since1982]

We have an Alpha combi boiler approx 12 years old. On Thursday morning the heating came on but there was no hot water. Later in the day there was hot water. This pattern has continued. There is no hot water when the heating is on but even if the heating is off in the morning / early afternoon still no hot water. Later in afternoon or later evening when the heating is off there is hot water. Is this the diverter valve failed? Alpha are coming on Monday. At the service a few months ago they said there was evidence of a build up of sediment and it needed a power flush which the plumber could do as a private job. I got a second opinion from an established local firm and was told it wasn't necessary and in any case pipework too small for a power flush. Im expecting Alpha to say on Monday that I should have had a flush and that the fault isn't covered. Any thoughts please.

Have you tried turning it off and on again?

i had something similar, theboiler's water pressure was too low. at least check and refill (some small valve underneath).

it did also precede some component failing inside, wasnt sure if the pressure was a symptom of the other at end of life.

Dirty gas

I recently had a similar problem, which was due to scale build up in the heat exchanger.

Intermittent jamming valve?

Thanks. Have checked that and all good. I sense something (other than me) is failing.

Caused by sediment

What size is your pipe work that it can’t be power flushed?

Very good question my friend.
Not taking the piss but it’s definitely a good question, @Since1982 can you post any photos of pipes going to a radiator

I did think it was odd asking plumbers for advice that early on a Sunday morning, five minute job reply didn’t get posted until after an hour.

It sounded like the established local plumber was talking out of his arse

I priced a smallish job Friday days work, the customer text me back that’s fine can you do Sunday
