Also on the lookout for a gas heater or oil heater. which 1 is better and why in terms of price,maintenance,electric use,etc.
game has 1 for R599 gas heater.
I have both. The oil heater appeared to be very expensive to run (in fact I have not used it since the first major electricity price hike) and takes ages to warm a room. With gas the room heats up very quickly. Though I suspect, with current gas prices, the oil is probably cheaper to run.
Burning gas also produces moisture, so the air does not get as dry as with oil or electric heaters.
The cost of running a gas heater really depends on how much you use it, and what setting you use it on. In mid winter I will go through a 9Kg bottle in a week, but then I work from home too, so it is on a lot, office in the day, lounge at night.
The trick is to look at the gas consumption specification, for instance, the Goldairs (9Kg) are around 110g / hour on a single panel and 290g / hour on three panels (

So the cost of running the heater from there is just maths. Hours * hourly consumption (depending on number of panels used). Same as electric heaters actually, just look at the input Kilowatt rating and take it from there. I suspect you will find that the output kilowatt rating for gas is higher for gas than it is for oil, so you also get more bang for you buck.
I have an old Goldair (about six years) whose panels have degenerated over the years. The more used the panel, the less they 'glow' and produce warmth. Thus, the middle panel hardly glows at all, the second panel glows OK and the third glows as if it was new. I am not sure if this a quality issue when it come to Goldair's panels specifically, or with gas from a particular supplier, or a bit of both. That heater will shortly be consigned to the scrap heap.
Someone mentioned getting a 9Kg unit, and sure the gas will last longer, but lugging a 9Kg unit up and down stairs (if you have them) can be a real pain in the buttox.
If you go for the smaller unit (up to 5kg) be aware that the 4.5Kg Alva gas bottles are about R100 cheaper than Cadac or LK equivalent, or that was my finding recently. I prefer to have two gas bottles per unit, so if one runs out I can swap over immediately, but that does increase setup cost.
Last but not least, I expect we can look forward to rolling blackouts again this winter. In which case only a fire or gas is going to keep you cosy at night.
