I have recently fitted new TRV's to all my rad's bar the bathroom. Now the main rad in the sitting room shuts off after a short period of time and will not come back on. All the other rad's stay hot.
I have also noticed the boiler stays on all the time now and doesn't shut off like it used to when it was hot enough.
Anyone have any idea's.
