Design/engineering and installation of brine | water heat pumps
 what is the purpose of the heat pump?
 what heat source supplies the heat pump?
 How are the heating surfaces designed? low temperature heating systems are recommended.
 what is the required heating output? Calculate the heat demand.
 obtain permission from your power supply utility [if required].
 Determine the operating mode of the heat pump according to the heating system.
 How can the heat pump be integrated easily into the heating pipework?
 should DHw be heated by the heating heat pump?
 is a suitable location that is free from the risk of frost available for the installation of the heat pump?
 where can the heat pump be located? Provide foundations.

How do i make the power connection?
 observe general requirements and guidelines.
 observe conditions on site.
Brine | water heat pump with geothermal collector
 Must your local water board be notified?
 is sufficient property available for the installation of a geothermal collector?
 Can the geothermal collector be installed at a depth of 1.2 to 1.5 metres?
 Can the pipe circles be split and buried equally?
 Can the flow and return distributor be installed outside the building?
 All lines and fittings/valves must be made from corrosion-resistant material.
 Can the geothermal collector pipes be routed with a gradient to the distributor?
 insulate the heat source lines inside the building with vapour diffusion-proof material.
 First mix the brine concentrate with water, then fill the mixture into the heat source system.
 Prior to commissioning, fill the system with brine and pressure test it.
 Use only a circulation pump that is resistant to brine and condensate.
 the brine increases the pressure drop. take this into consideration when sizing the pump.
 the changes in volume require the installation of a brine resistant expansion vessel.
Brine | water heat pump with geothermal probes
 is a permit required from your local water board?
 is sufficient space available for the geothermal probe hole?
 Can the probe lines to the distributor be split equally?
 Can the flow and return distributor be installed outside the building?
 All lines and fittings/valves must be made from corrosion-resistant material.
