When Calor announced in 2017 that new Calorlite would no longer be made, this followed an earlier safety recall, I decided to see what options were open to me. I used to carry two 6kg propane steel when away for extended periods. One for the caravan systems and the other for the BBQ. Even with Calorlite I continued that practice, and then just had one cylinder if in UK when the BBQ/Cadac wasn't to be carried. Or the BBQ/Cadac was fed Camping gas from my lightweight camping cylinder. (Cost no object)
I considered refillable cylinders including Safefill and Gaslow. Firstly the price wasn't attractive for composite or steel self fill cylinders, and the latter were heavy. There also seemed to be a trend where autogas was becoming more difficult to source so I was conscious of possibly being left with two bottles worth around £400 that were effectively rendered obsolete. Also I looked at the life expectancy of self fill cylinders particularly as they have components that could require replacement or possibly fail. On the Safefill website it stated that the cylinder was warranted for 10 years but some components only two years. Safefill also stated that iaw " guidelines" the cylinder should be inspected every 10 years. The current website now says "recertified" every 10 years. I actually telephoned Safefill and asked "how is a cylinder inspected?" for life extension. Did they have a procedure through their authorised outlets. To be blunt there was not any procedure or system in being. Which did not give me a warm feeling. Now Safefill have a system whereby if an owner registers their bottle they may contact them at random to invite the owner to have the cylinder inspected. Of course this has a weakness that if a cylinder is sold or moves on with the caravan it may not be re-registered by the new owner.
So as we were not large users of gas, even on CL/CS we looked for EHU hook ups, I stayed with my Calorlites, until eventually one was replaced with a steel 6kg propane. Had I gone to lightweight composite cylinders I would have gone for the Gaslight on the grounds that the exchange cylinders are subjected to a comprehensive inspection and replacement of any parts that may be required before being returned for sale.
Members may not be aware of the comprehensive procedures that exchange cylinders for the major players are subjected to in order to ensure safety is not compromised. Such procedures cost money be that labour costs or investment in capital equipment. Calorlites were withdrawn because so many were being scrapped on account of damage. They were more costly to repair, or could not be repaired. This came at a time when cheaper Chinese imports started to arrive, which were of lower quality and some were probably even being refilled by owners using imported adaptors of dubious provenance bought on Ebay or similar, as reputable gas equipment companies would not supply such parts.. This trend is what has doubtless driven Calor to further rationalise their range of steel cylinders, in order to maintain profitability.
I append a report by the World LPG Association which although 2016 is still relevant. It illustrates the approach adopted by a number of countries and UK's approach is at page 53.
