I wanted to buy a gas heater that uses the yellow 11.3kg bottle. I mistakenly (my own fault) purchased the mini to find that in the user directions with the heater delivered said I needed a 7kg bottle. Couldn’t find one locally (suppliers never heard of it) so I returned the heater and I am awaiting a refund. I then bought another heater that did use a 11.3 kg bottle but the regulator that was on the new heater didn’t fit the 11.3 bottle so I had to purchase and fit a new regulator. Delivery of both heaters was fantastic. It should be clearer about bottle size and regulator . I have told this to a few people and they all said they would expect a heater and regulator to fit a 11.3 kg bottle. If that is not what is on offer it should clearly say so. Hope comment is of benefit. Ger Power
