Hi All, I have been watching with interest the threads about Gas and the alternatives to Calor etc. ,,,,, 'Oh, No says SWMBO, another project'. The parts I am interested in is the differences in the gas and install itself. a) Is (garage) LPG the same as propane as far as 'the burn' is concerned? b) Do the appliances/gauges have to be modified - jets, pressures etc? c) Is the mod an insurance 'notafiable alteration'? d) Does the LPG system need certification - like a car (ten years ish)? e) Is the low temperature use an issue - like Butane v Propane? Enough questions for now - I am considering it, but our gas use won't justify the outlay - just yet - but it may do in the future. Regards, Trikeman.
