Circulation system
A hot water circulation is not recommended for energetic reasons. If a hot water circulation is necessary due to unfavourable ducting, it
must be carried out according to the standards (see „13.2.3 Hot water generation“ page 102)
Geothermal heat exchanger
The temperature in the earth is almost constant throughout the year. Thus, the heat exchanger is suitable to pre-heat cold outdoor air in
winter. Warm summer air can be cooled down before entering the interior rooms.
- Air-to-air geothermal heat exchanger
The air to air geothermal heat exchanger should be connected to the outdoor air of the heat pump to ensure higher energy efciency.
A combined connection to the ventilation unit is not possible due to a varying supply air intake of the heat pump. This results partially in
high volumetric ows and a proper controlled residential ventilation operation can not be ensured.
- Brine-to-air heat exchanger
A brine to air heat exchanger is an alternative. Both supply air intakes can be connected together due to the separated systems. Ensure
that the specications of the brine to air heat exchanger is adapted to the heat pump (air ow rate).
