We are experiencing an intermittent fault with our central heating
We have a Worcester Bosch Highflow 400 controlled by a Drayton RF2
(both around 10 years old)
The Drayton thermostat and receiver are communicating but the boiler is not responding
The heating light on the Drayton SCR will be on but the boiler demand light doesn't come on and we don't get any heating
(Hot water is unaffected)
Is there an easy way to confirm where the fault lies?
I am happy to replace the Drayton but don't want to do that then find the boiler is the problem
