A plumber has just asked me to tell him the output of my boiler (and says it will be written on it somewhere). I have a Glow worm Fuelsaver MK2. Does anyone know what output this would give? (i'm not sure whether each model only produces one possible output or whether they come in different outputs)...
I wonder if anyone can help? My central heating system has started making a high pitched whistling noise ( a bit like an old fashioned kettle when it had boiled) but i'm not sure whether it is coming from the boiler or the system itself. Does any one have any suggestions as to what could be the prob...
