Any central heating engineers on here?

[gavroche]

Recently, my 13 year old Vaillant combi boiler has developped a mind of its own. The central heating comes when it feels like it , even when the temperature is over 20 degrees outside. It is controlled by Hive and that is set very low at the moment ( 10 degrees). I have turned the temperature control down for c/h on the boiler but I am not confident it will be sufficient. What shall I do? Call an engineer? Will I need another boiler? Thanks in advance.

Comfort Setting?
Check for a "c" on the display.

Is it coming on at the same time as you use hot water?

No, just when it feels like it. Anyway, I have a service contract with Corgi and have contacted them. An engineer will call me within 24 hours to book an appointment. It will cost me £60 though! Rip off considering I pay a monthly fee already but I have no choice, that's the way the service industry seem to work nowadays.

My first thought, diverter valves / motors can stick / fail and send the hot water to the wrong destination.

When the boiler comes on, does your Hive App still show the Central Heating set to Off? Just wondering if someone has hacked your account.

The Company is called Corgi but they use GasSafe local engineers.

Update on the c/h. The engineer has been and the boiler needs a new pump and a new diverter. I am glad I am not paying for that as the parts are expensive he said.
Worth paying my insurance premium then.

Surprised your insurance will pay out for "wear and tear"........unless it is specific of course.
Nice result if it does though
