5.6 BoxAir and BoxAir Inverter system connection
BoxAir heat pumps are dedicated for outdoor installation. Heating system piping has outdoor
installation, therefore antifreeze must be used for heating system filling.
5.6.1 Single loop heating system
Typical usage is for floor heating, except for “dry system of floor heating”. In this method of
direct connection of the heat pump to the heating system, maximally 30% of the heating system
can be equipped by local regulation. In the case of usage for radiators it is also necessary to
comply with the requirement of minimum heating water volume of 15 l/kW of the heating output
of the heat pump at B0W35. Heating of DHW is provided by a 3-way switching valve. Regarding
the type of DHW tank, follow instructions in Chapter “Preparation of Domestic Hot Water”.
