Glow-worm Ultimate 50 BF - Boiler supplies a pumped Heating system only.
The Thermostat does not really control the temperature, even when on the minimum settimg the Flow temperature is very high.
I replaced the thermostat but it made no difference.
Would appreciate any advice on the next step
thanks Ian
