Riello RDB Boiler not firing for heating only

[Deleted member 111148]

The boiler is working fine for hot water but not for heating. Timer is on 24 hours and the thermostat 'clicks'. Any suggestions appreciated

Is it twin motorised valves? An S plan, potential issue with central heating head or valve.

Hi Simon Thanks for the reply. To be honest I don't know, how can I find this out?

You look at the motorised valves - typically beside boiler, or in airing cupboard, etc, and see if you have one with 3 pipes connected to it, or two valves (or more) with 2 pipes connected to each one.
Simple.

Pictures of where your pump, cylinder and controls will help.
