Last wood burner we had was supplementary to Oil central heating over 3 months we got through about 1te of Elm that I got from my dad. It looked like loads when it was stacked up but went very quick.
When I was living at home we had 2 log burners doing all the household heating duties (water, CH and general room warming) being on a farm access to wood wasn’t much of a problem but it was time consuming, there were tree’s felled and stacked up, every time you collected one you felled another. Each summer/autumn it was time to get the log splitter out, even with that it would take at least a day maybe 2 to get through enough wood for the winter, stack or bad it it – now most of it goes into 1te dumpy bags that can be moved with the tele handler much quicker.
So despite having free access to wood, chainsaws, a log splitter and enough space to store all the split wood my dad built an extension and put an oil boiler in. He still uses wood for the living room fire most days and the range in the dining room sometimes but leaves the heating to oil.
