Hi
I am not a plumber but as far as I remember I was told that the towell rail in the bathroom was the bypass.
Would that be correct?
If you are sitting on the bog and the boiler shuts down due to the room stat you hear a diverter valve move and then water rushing through the towell rail...
There are 2 22mm pipes from the top of the boiler, I just checked it but the boiler had been running recently.
As the boiler fired up, both of the pipes were quite warm, then one of them started cooling and the other one started heating up.
Is that what you wanted me to try?

Hi
The radiators have been bled and there does not appear to be any air in the system. The header tank has also been checked and the water level is ok.

Hi
This is my first post so hope its ok.
I have the above boiler and it locks out, here are the details.
With the boiler control set at 3 there is no problem but if I increase it to 3.5 it locks out INTERMITTENTLY.
The boiler runs as normal and when the room stat shuts it down the pump...
