So which is a more feasible heater, gas or electric?
PS. Anyone can do the math ?

The cheapest is to dress warmly, thick socks, nice warm tracksuit pants, decent t-shirt and hoodie (even better if a Mybb hoodie)

roof insulation, good point to begin.

...I'm guessing you're sleeping outside tonight because you're all "manned up" and don't need a roof over your head?
C'mon, man up and either help the guy or post something that's legitimately funny instead of something pointless.

I'm actually curious about the same. Renting a new office and some of the staff get cold at the drop of a hat (like blanket, jacket and stuff at 15°). Now if only there was a way to store summer heat for winter, but I think I'll have to go gas...unless anyone has done the math before? I think panel heaters don't use much electricity vs other electric alternatives, or even when comparing their energy cost to the price of wood in these parts (we have a fireplace).

Electricity based resistive heating and gas based heating are almost the same per kWh. If you are only going to use it a few times a year a gas heater is nice and can heat up a whole room quickly.
An air conditioner that can work in both directions (colloquially called a "heat pump") will do 2-6 times the amount of heating per unit electricity as a resistive heater (it moves heat from outside to inside like a pump moves water), and you get to use it to cool down a room in summer too!
We have three portable aircons and they work really well
There will be no efficiency difference between a flat panel wall heater thing and an electric oil fin heater on wheels. They are both resistive heaters.
In conclusion - if you will only use it 10 days of the winter get a gas heater. If you want an aircon for summer then get an aircon that can heat the room too

Holy crap it's like R15000 for a heat pump!

How big is/are the room(s) you want to heat/cool?
Rule of thumb people usually use is 12000 BTU/hr is enough for 20 m^2, and you use that ratio for whatever room you are trying to cool/heat.

This^ I prefer it gas as well. seems to heat the room much better.

3 rooms, total size in terms of square footage is around 2 double garages.
I bought a 3 panel Goldair gas heater last year.
It is fantastic - heats up the room superbly.
I used less than a gas bottle (I share the bottle with my braai) for winter.
There is a bit of a smell when using a gas heater - but nothing crazy

It's great but if you get cold easily or live in a damp house or in the colder cape winter months especially on the coast you can easily use a gas heater for 6 hours a night on on one panel or two
And then use it again in the morning to warm up a freezing living room quickly - some winters my kid dresses for school in front of the heater !
So one 9 kg bottle won't last a month but that same bottle used for a gas cooking stove lasts several months
Plus it's a chore lugging empties to be refilled and lugging them back
Sometimes a small Cadac with a heat element attachment works like a treat when your electric panel heater takes too long to warm up
Oil fin heaters are great but they do suck electricity
Caveman style - naked!
Panel heaters don't use much energy because they also don't heat very well. Efficiency is about the same.

We have four panel heaters across 3 rooms. The one in the bedroom has split down the middle twice. One was a Salton and one is an EconoHeater. None of the others has ever split down the middle. And I drilled fresh holes for the replacement EconoHeater so I don't think it's the installation... Anyone have any ideas what's causing it?

It's extra hot in the bedroom
