Hi, can anyone help me with my boiler. The heating isn't coming on although I am getting hot water no problem. The salus remote thermostat is showing a flashing flame whenever I adjust the required temperature which I presume is telling the boiler to fire up - which it does but nothing happening with the radiators?? The display panel on the boiler is saying "no heat demand". It seems as though everything is working fine but no hot radiators.......help!
