Domestic hot water recirculation
As standard the S 22 is supplied with a low energy pump for domestic hot water recirculation and can easily be connected to existing systems with DHW recirculation.On new constructions it is recommended to establish domestic hot water recirculation, which ensures that hot water is produced immediately, when tapping starts.This ensures maximum DHW comfort and eliminates water wastage.
Heat exchanger for DHW heating
The heat exchanger used in the S 22 is a brazed, highly efficient Danfoss plate heat exchanger, which has been tested and approved according to the PED directive.
Reading and setting
All thermometers are placed so they are easy to read.Components, which can be adjusted, are easily accessible.
Maintenance
The substation is very service friendly due to practical piping and assembly with nuts and gaskets.It is mounted on the wall and as all pipes are placed in pipe bracket distance, it is possible to establish a nice piping.
