Very big Orlan wood burning stove + 1600 Ltr tank

Huge Orlan log burning stove + 1600 Ltr stainless buffer tank + all necessary pumps and fittings. The system was hardly used but when it was in use it rapidly heated a 2200-square-feet house. The price of logs increased and it was not viable to continue using it. Cost £7000+ to have installed. Has automatic thermostats that regulates the the temperature by starting/stopping of fan and automatic switches from heating the house to heating the Buffer tank when the house has reached the set temperature.
