I wish to find out what heating solutions there are that don't connect
to the mains electricity or gas supply. Something that could be used to
heat a single room or so. I thought that there were oil burning
heaters, but the ones I find online are generally large "permanent"
heaters. Wood pellet burning stoves seem to need proper installation
and a hearth. Are there any types of heating that are worth looking at?
I would prefer something small and relatively cheap-ish, which can be
plonked down in a carpeted room as a heater.
