Distance
Install the heat pump as close to the swimming pool as possible to minimize the loss of
heat through the piping. Put it on a solid base and place the rubber blocks under the heat
pump to eliminate vibrations.
Normally, the pool heat pump is installed within a 7,5 meter radius of the pool. The
minimal distance to the pool is 3,5m.
The greater the distance from the pool, the greater the heat loss from the piping. Since the
piping is buried for the most part, heat loss is minimal for distances of up to 30 meters (15
meters to and from the pump= 30 meters total),unless the soil is wet or the water level is
high. Heat loss per 30 meters could roughly be estimated at 0.6kw-hour (2000 BTU) for
every 5 temperature difference between the pool water and the soil surrounding the pipe
which translates to an operation time increase of 3-5%.
We advise the installation of a proper 50mm tube insulation on aboveground tubes.
Installation of the check-valve
When using automatic chlorine and PH dosage systems, it is of uttermost importance to
protect the heat pump from high concentrations of these chemicals that could corrode the
heat exchanger. Therefore, such systems should add the chemicals in the conduits located
DOWNSTREAM of the heat pump and it is recommended to install a check-valve in order to
prevent backflow when there is no water circulation. Damage to the heat pump caused by
disregarding any of these recommendations will invalidate the warranty.
