• The swimming pool heat pump is usually installed near the swimming pump at a maximum distance of
7.5 metres. If installed beyond this limit, the technology system (pipes) can cause higher heat losses.
Most pipes are installed underground, and although the technology system (pipes) must be provided with
thermal insulation, all tunnels and surrounding soil will still receive the heat, unless the ground is wet
or the water level is high. A very rough estimate of heat losses for 30 metres (15 metres to and from the
pump = 30 metres in total) amounts to 0.6 kW per hour (2,000 BTU) per 5°C of the water temperature
difference in the swimming pool and the ground around the technology (pipes), which increases the run
time by 3 to 5%.
• To achieve the best exchange of heat of the heat pump system, ensure normal water flow according to the
specifications.
4.3 The position of chemical elements in the system is also fundamental to the service
life of the heater.
If an automatic chlorination or bromination system is used, a trap must be installed downstream of the heater.
A water seal must be installed between the chlorinator and the heater to prevent chlorine from returning into
the heat pump (see the following figures).
