TERRA SWM HGL with direct heating circuit
The TERRA SWM HGL is a modulating heat pump. Therefore, it is possible to provide heating circuits directly
without a storage tank! An additional pump and a mixing valve for the heating circuit is not necessary. The
Hygienik will be provided over the HGL-pipe. An additional expansion tank must be installed in the return of the
heating circuit. The overfl ow valve in the heating circuit must be set to give a proportional fl ow to the number
of closed zone valves.
With this hydraulic and the modulating operation, can be cooled without a cold storage tank. For dew point
monitoring, a room humidity sensor and a dew point switch must be installed.

• The heating emission system has to be fl oor heating. 1/3 of the fl oor circuits has to be opened
always. Area valves must not be installed.
• At direct heating circuits an overfl ow valve has to be installed to guarantee a minimum fl ow, so
that the heat pump is not clocking.
• For the size of the expansion tank the capacity of the hygienik tank has to be counted in.
