Vokera combi. No heating.

[pigwidgeon]

Vokera combi works fine for hot water. But to get heating, I must first cool it down with a blast from the filling loop and out of the blow off. Then press the reset button for an hours heating.. Tried ferroquest. Nothing. Is it the fire drive thermistor? If so where is it located? there's 4 thermistors.

Vokera make lots of combination boilers. You need to be more specific.

Why not do yourself and your sister a favor and get someone to look at it who knows what they are doing.

From this comment alone you clearly don't.

Actually there is only ONE thermister in this boiler! Easy enough to check it with your meter on the first visit!

This poster was giving advice to someone else here but seems to have more than enough problems dealing with this simple boiler for his sister.
