I'll stick with the meter - can't humph string bags of logs about any more, and I certainnly couldn't make anything out of an old gas bottle for fear it would explode while I was working on it

I watched Kirsty Allsop last night =- they got an old log stove from a fireplace shop for nothing. Looked prerty good too.
Sandy, you can boil a kettle on any flat topped wood/multi fuel stove. I did on mine last winter when we had a power cut - actually cooked a whole meal on it. Did the same with the one in the house I built too. One of the reasons for putting them in to be honest - in case of power cuts you can survive as long as you have something to burn. I'd never install one of the sloping topped ones, or those with very little top surface.
Something to bear in mind with yours David.
