I have one refillable Gaslow bottle and a Calor Lite bottle. The Gaslow bottle has been used for 4 years. I have never run out of gas. I top up regularly when LPG is available on a forecourt. The Calor Lite has never been used until a few weeks ago when I deliberately used it until empty - knowing that the lite bottle was discontinued. I don’t feel I want to replace the Calor lite with a full bottle - Calor or otherwise - to remain unused for yet another 4 years. I am therefore contemplating using only the Gaslow bottle and using a single burner Campinggaz stove as a backup should I ever run out of gas. We seldom stay on a site which does not have an EHU. Has anyone gone down this route? I would welcome comments on my plan.
