hot water problem

[TJT87]

Hi guys,
I've got a volkera linea 28 combi boiler, recently when running the hot water the temperature has started to fluctuate between hot and cold. Also I've noticed that the pressure has started to creep up, gone from just over one bar to two point five. Is it a problem with the pressure valve and if so is there an easy (Cheap) fix

Could be a couple of issues there. It may be the expansion vessel has failed, the plate to plate is partially blocked, the filling loop is letting by, etc etc.

Best bet get recommendations for a good heating engineer to come take a look, they might charge you a call out or diagnostic fee but least your know where you stand.

It won't get any better with time.

Why do you want it fixed on the cheap?

Most people get their boilers properly serviced every years and any issues identified then!

I do get my boiler serviced each year, it's about six months off, and why wouldn't I want it done cheap.

Why do you assume?
