Ideal Isar HE30 no heating

[Coogan]

Morning all, just want to get an idea of the problem before I call engineer. Have been ripped off in the past, so....

Hot water absolutely fine. First time I’ve turned CH on this year, it makes all the right noises as though on, display shows ‘c’, pressure fine, but the rads still stone cold. Bled all the rads, still no different.

Any ideas? Thank you

Diverter valve, very common fault on these.

Could be anything , gas safe man required

Misread this initially. If it’s showing ‘c’ then it’s recognising the heating demand, do you have the boiler stat and room stat turned up?

Yes to both. The CH / ‘c’ wouldn’t kick in if the thermostat was set too low, before the ‘click’.
