There are several considerations in deciding where to locate the outdoor unit.
- As close as possible to the plant room to avoid unnecessary heat loss.
- Although many air source heat pumps are extremely quiet, if possible it is advisable to position away from bedrooms where any noise could be an issue.
- Areas that do not allow air to circulate freely around the air source heat pump or “frost-hollows” should be avoided to prevent a vicious circle of supply air from getting colder reducing the efficiencies.
- Avoid the potential for dropping leaves or debris that could disrupt airflow into or out of the unit.
- As the ASHP blows out cold air, locating the unit adjacent to footpaths, doorways and plants that may be sensitive to frost should be avoided.
- A working ASHP can produce up to 25 litres of condensate a day which needs to be taken to a soak-away or drain.
