4.2. Space requirements
The heat pump requires 50mm more floor space to the side of assemblies than its external dimensions. Lämpöässä
T10-T31 and P10-31 geothermal heat pumps are 1.3-1.4 metres in height. Approximately 0.4 metres of space must
be reserved for the assemblies on top of the heat pump. This should be taken into account when placing the heat pump
in a low room, such as a basement.
The Lämpöässä geothermal heat pump should be installed in a warm, insulated space which has a floor drain, because
some ground loop fluid may be splashed on the floor when the ground loop is filled. The chosen area does not need to
be fireproof.
