Ok so i hacksawed out the old lethal backboiler, lagged the inside of the cavity with concrete mix... and i might be aquireing a squirrel stove.... possibly with a backboiler. Now you can tell what i'm thinking. All the rads etc are there, pump is there. piping is there..... what does someone more sensible than me think?...is it possible to just substitute a stove for a gas back boiler. i know the pump etc needs thinking about, but possible?
