Wood heater technician?

Hi all

Looking for someone to help me with some solutions for my wood heater. It’s been installed by the previous owner to sit flush in an old open fireplace and all the heat is being lost in the surrounding brick and up the chimney. There’s also no hearth. It’s pretty inefficient and our main source of heating - our house is cold even though it’s 60sqm cottage (getting underfloor insulation installed next week).

I’m wondering if the wood heater could be uninstalled, moved and reinstalled to be freestanding within the house and then the old fireplace blocked off?

I can’t find anyone online who could do this. Any leads would be much appreciated.

Thanks!
