It is worth pointing out that there are wide range of retail gas bottle vendors throughout the world. Either companies can offer you gas bottle exchange almost anywhere. Several other brands are also available in boarding countries around Africa. They expand to other parts of the continent also, in West Africa. Some British colonized countries uses UK standard regulators, valves, and fittings - so make likely find the two main propane distributors in the UK: FLOGAS and CALOR-GAS in these countries. Furthermore, commercial LPG is supplier in two forms - Propane and Butane. Filling a cylinder bottle with the wrong type of LPG can lead to serious appliance malfunction and can cause safety devices to fail.
If you are traveling to West Africa countries, you can often find refills at some petrol stations near popular camping routes or major roads, usually small independent petrol stations. However, you need to know the type of LPG gas sold at thee various gas stations. In continental Africa, few country rely exclusively on butane, but majority a mix that includes a minority of propane. If you plan to travel or settle in any country in West Africa for an extended period, check out LPG delivery service with that area of settlement. Ask if they offer exchange bottle delivery. Exchange-only gad bottle can be replaced with a whole brand new with gas, which cost less than refilling at gas stations. You can enjoy the next day delivery service at no extra charges above the normal exchange fee when you registered.
You can get variety of gas cylinder sizes and shapes from various local vendors, which can fit in your storage. Although, the general names might be different from one sold in each African countries. You can see the 6.8kg, 13kg, 8kg, 4.8kg and so on. Some country in Africa offer lite propane cylinder bottles, which is less heavy, and also stainless steel container may be the more convenient choice for use in these countries.
They may offer a bottle size large enough to satisfy the cook and yet fill in your storage, and you won't be needing so much cylinders stored in your storage room. I found also that the 12.5kg tank sold in Nigeria is just slightly smaller than the one sold in other African countries. Inspecting the gas bottles, I found the sizes and shapes to be different. Nigeria 12.5kg is taller and narrower than the one outside the country. Keep in mind that in some country in West Africa, LPG forms are Identified with colours - for Propane and Butane. RED tanks are intended for propane. This means you may have even more options for the butane BLUE tank sizes, provided you are willing to burn butane. You can choose a smaller 3.9kg gas bottle prior to your stay in that country, but obviously, it hold less LPG and therefore need to be replaced or refilled more often.
