I have an account with Flogas for their LPG auto supply pumps from when I had an underfloor tank in my previous (stolen) camper. My local Flogas supplier is just a half-mile from home, so I thought it would be sensible to change to their bottles instead of my new 6kg Calor cylinders. They refused to sell me any new 6kg cylinders because of the very shortage I was hoping to circumvent. That's taking it a bit far. So I'm thinking of fitting a 6kg Gas-it refillable which are on offer at the mo. They're on offer before they restock with the new 2031 cyinders. What are they? Anyone know?
