To ensure that hot water is available at the taps, an inline recirculation
system can be connected to the HFS. The inline recirculation system
is not part of the boiler and must be ordered separately. Be aware that
the boiler temperature is reduced by the complete recirculation line. The
following hydraulic configurations can be used.
The recirculation set is connected to the outlet of the hot water boiler,
directly in series with the outlet or as diversion through use of a T-fitting
(depending on the flow). The hose must be inserted in the hot water outlet
over a length of at least three meters and connected to the return line
of the recirculation line and the cold water supply of the thermostatic tap
water mixing valve. A timer must be installed for the recirculation line.
