In reply to Sharp: Cheers everyone, I'd kind of hoped gas would be a good idea but maybe it'll be more expensive than I'd thought and I hadn't really considered how quickly the bottles would empty. It's infuriating that they dug half my street up to install gas lines but stopped about 40m from my front door.
I should maybe just stick with the stove that's in until it collapses, I think the best option for the house would be some sort of low level background heating/hot water system in addition to the stove but anything like that I've come across has been out of my budget.
I don't fancy oil to be honest, I had it once before and I think it'd probably be something I'd regret getting in the long run.
If I'd burned only wood last winter I'd have spent a lot more than £100 a month, I'm not sure if it's just the old stove but you could burn £50 worth of bone dry hardwood wood a week and the average temp would still be single figures. Coal all the way next winter.
Cheers everyone
