4.3 Integrating in an existing unit
The stove with integrated heat exchanger for the heat sink is suitable for incorporating in
existing units which are constructed as closed systems.
The safety valve on the central heating boiler in the cellar cannot cover the heating stove
as well. A separate safety valve should in any case be provided near the heating stove.
It is absolutely necessary to consume, respectively to store up the energy of the added
cooker. A buffer reservoir of 50 litres per kW water output is normally sufficient for buffer-
