Been to a vitodens 100 that is warming up and shutting off quite quick, the pump is spinning and adjusting speed no problem however heat isn't being transferred to rads or cylinder.
This vitodens model is the earlier one without the air vent on off heat exchanger , I'm starting to think it might be air trapped in there , although it's not kettling.
Any ideas on best way forward with it, i.e. Best way to vent the heat exchanger
thanks
