How hard would it be to move / rotate the stove in this picture ? Moved into a house but in my opinion the stove is not at optimum position because it is facing away from where people are sitting. My ideal situaution would be to have the stove to the left of the television, facing in the same direction as the television.

Probably not too hard, but you’ll need a Hetas-qualified person to move it. Some flue work, refix the seal into the stove, ensure there is a hearth of the right dimensions and correct distance from anything that can burn. You have a CO alarm? It’s just possible that they need to ‘re-install’ to modern regs, which might make it tricky. Easy enough to get a Hetas guy to give you a quote?
