Siting the Heat Pump
3 Siting the Heat Pump
The North face of a building will usually
have colder ambient air than any other
side. To ensure maximum efficiency
from the Grant Aerona heat pump,
position the unit on a warmer side. In
order of preference, site the unit on a
South face followed by either South
East or South West, then by East or
West. Only install on a North face if
there is no other alternative.
