OK, so ignore all the negative posts regarding difficulty with gas bottle sizes, this product is BRILLIANT!, and it really is not an issue if you use your grey matter and do a little research first. Amazing for the price, really well made (I don't know how they do it for the price!), sturdy, puts out loads of heat, can't fault it at all. We love it! I assembled it myself (and I'm a girl), it was dead easy and my partner only aided at the very end to hold the top while I reached the last nuts (a ladder helps here too so you don't have to tilt it). It took me around half hour. No, 9kg gas bottles aren't available in UK, but there are others that are absolutely fine. The problem people are having I think is not to do with the KG size of bottle, but more to do with the varying supplier brands and their bottle measurements, and the varying regulators, which each have different sizes and pressure. Calor Gas bottles measure larger than Flogas for the same size KG for example. We measured the space available for the bottle after putting it together (33cm width max, and 58cm height max) and then researched the measurements of bottles available with each supplier, and their regulators. Propane bottles don't often use the same size regulators as Patio Gas bottles even though they are both Propane Gas, which is where people get confused I think. Yes, you can always buy a different regulator to fit and they are cheap, but the varying size regulators also have varying mbar pressure, so may not necessarily have enough pressure to use the heater to its highest setting. It will work but not anywhere near as hot. Butane for example works, its cheaper and you can fit a 13kg Flogas, you can but a £7 regulator to fit, but the regulator is only 29 mbar so doesn't kick out enough heat. It needs 37 mbar to really do its job. The Patio Heater comes with a 27 mm snap on (size and type) 37mbar (pressure) regulator provided for a reason; it is the right pressure to work to full heat, and it connects to PATIO Gas Bottles. Flogas do an 11kg Patio Gas (Green gas bottle) which fits into those measurements, and uses the regulator supplied with the heater. An economical kg, and fits fine. Yes, it sits ever so slightly on one of the base bolts instead of inside it, but this really is NOT an issue as one post mentioned, the bottle is not unstable. Zoom in on the photo to see for yourself. If you want to look for a bottle that is less than 27cm in width so it fits inside the bolts, do, but it will likely be so small it wont be economical. So there are lots of options but if you want a big economical bottle, that fits the regulator supplied, pumps out maximum heat, the Flogas 11kg Green Patio Gas bottle works great.
