Central heating

SAUK

In November we had the radiators replaced and the cylinder changed to an unvented system (at the plumber's recommendation)
The house hasn't been as warm since.
Last week the plumber identified that the boiler we had installed in 2016 was too small for the house. We think this should have been identified earlier (before winter ideally)

Do we have any rights in this situation?

To some extent, it depends on what you asked for.

If you asked for rads to be replaced, and he suggested a new cylinder, and he has done what was agreed, then I cannot see that there is anything amiss here.

Yes, it would've been nice if he had spotted the the boiled was not big enough, but perhaps any calculation on boiler sizing wasn't deemed necessary until after the job was completed and wasn't performing as expected.

Thanks. It's been immensely frustrating but I suspected we wouldn't be have any come back.

How many radiators and what is the boiler make and model? It could also be the radiators, if it was hot enough with the old radiators then you need to question why it's not hot enough now.

You could check the scheduling of the water heating and the central heating.

If both are programmed to start heating at the same time in morning, the water cylinder might be given priority, so until that has heated up, the heating won't be working fully.

If that's the case, you could program the water heating to come on an hour or two earlier.
