THE CLOSED CIRCUIT
This method was designed to make installation of the Biothermal Fireplace heating system possible in all those interiors where the expansion vessel cannot be positioned at the highest point of the house.
HOW DOES IT WORK ?
For security reasons, the Biothermal Fireplace heating system works with an open vessel, while the system works in closed circuit in order to merge it with almost any other type of closed circuit heat generator.
THE ADVANTAGES
 The expansion vessel is pre-assembled in the Biothermal Fireplace heating system, therefore it does not need to be positioned in another part of the house.
It can also easily be installed in blocks of flats and office buildings.
It is easily installed thanks to the provided kit, complete with 2 pumps and an exchanger.
Low labour costs.
