3. INSTALLATION AND CONNECTION
3.2 Swimming Pool Heat Pumps: Location
The unit will perform well in any outdoor location provided that the following three
factors are present:
1. Fresh Air - 2. Electricity - 3. Pool filter piping
The unit may be installed virtually anywhere outdoors. For indoor pools consult the
supplier. Unlike a gas heater, it has no draft or pilot light problem in a windy area.
DO NOT place the unit in an enclosed area with a limited air volume, where the units
discharge air will be re-circulated.
DO NOT place the unit next to shrubs which can block the air inlet. These locations
deny the unit a continuous source of fresh air which reduces its efficiency and may
prevent adequate heat delivery.
3.3 How Close To Your Pool?
Normally, the pool heat pump is installed within 7.5 metres of the pool. The
longer the distance from the pool, the greater the heat loss from the piping.
For the most part, the piping is buried. Therefore, the heat loss is minimal for
runs of up to15 metres (15 metres to and from the pump = 30 metres total),
unless the ground is wet or the water table is high. A very rough estimate of
heat loss per 30 metres is 0.6 Kw-hour (2000BTU) for every 5°C difference in
temperature between the pool water and the ground surrounding the pipe,
which translates to 3% to 5% increase in operating time for the water to reach
the desired temperature.
