Now that's an interesting stove, quite often to get a sensible amount
of heat into the wet system the room also "benfits" from rather too
much heat. Had a quick look on the website linked elsewhere and they
only mention the supplier of the thermal store not the wood burning
back boiler stove. Any clues to the supplier maker of it?
