Why convert it from solid fuel? I have a solid fuel Rayburn on my narrowboat, it only requires attenttion once or twice a day, burns relatively cheap anthracite nuts,
doesn't need electricity to operate (the oil ones have a pump) so no battery drain.
It's been alight since September, so no problem keeping it going.
..and there's nothing that can go wrong with it.
It's also worth considering where you are going to store your fuel, I can keep 4 months worth of fuel on my mooring. I think you would need a large fuel tank to do this, so in winter you might need weekly trips to fill Jerry cans.
I think oil Rayburns run on Kerosene not diesel, but I could be wrong.
