Aquatherm Eco P34 stove
This is the bigger version of the P26 the Aquatherm Eco stoves.
The P34 has a backboiler giving a maximum 24kW (82,000 BTU) to water and 10kW to the room.
This is an 80% efficient woodburner.
Easy to recognise as an insert stove with a big boiler and a door that slides up and out of view is very unusual.
