I was going to go down the diesel heater route - but the expense
I am going to buy one of the gasstop safety valves for £40 for my gas heater.
£100 for my fastar gas boiler ,a few fittings and gas bottle job done.
i like lots of others liked the idea of cheaper option of gas but the safety issues were a concern.
I have my boiler mounted on a trolley so can take in and out of van easily.
sometimes work with it out of the van all together .
With a gasstop i will work with more confidence probably using the heater a lot more.
