Can anyone help me?
I have a gas fired boiler that is used for heating and hot water.
If I put on the hot water only, it is fine.
If I put on heating only, it is fine.
If both are on, and a bath is run, the water is VERY slow to warm up, but the radiators get VERY hot.
The room thermostat has no control over the boiler.
It this the 3 way valve sticking?
Are there any checks I can do to diagnose the problem?
Thank you.
John.
