High efficiency
With a COP value of more than 5, these heat pumps show high efficiency at trans-
ferring heat from the ambient air to the pool water. By using them, you can save up
to 80% of costs compared to conventional electric heating.
Long life service
The heat exchanger is made of PVC with an internal titanium spiral tube and resists
long-term exposure to pool water containing commonly used disinfectants in com-
monly used concentrations.
Easy handling and operation
The device is very user-friendly: just turn it on and set the desired pool water tem-
perature. The control system includes a microcomputer that allows you to monitor
and set all important operating parameters, and displays the operating status on
the controller with LCD display.
3.2 Principle of operation
The heat pump uses a cycle of compression and expansion of the heat transfer fluid
to obtain heat from the air around the pool. The hot air is driven by a fan through
an evaporator, in which it transfers its heat to the heat transfer fluid (while the air
cools down). The heat transfer fluid is then transported by a compressor, which
compresses and heats it, into the coils of the exchanger, transferring its heat to
the pool water. From the exchanger, the cooled fluid flows to the expansion valve,
where its pressure is reduced and it cools down rapidly. Thus-cooled liquid flows
again into the evaporator, where it is heated by flowing air. The whole process runs
smoothly monitored by pressure and temperature sensors.
The pipes connecting the heat pump and the pool should not be longer than 10 m
and should be provided with suitable thermal insulation to retain heat. Longer and
/ or non-thermally insulated pipes have a negative effect on the heating efficiency.
3.3 Handling with heat pump
Do not lift the heat pump using the heat exchanger fitting. This may be damaged.
The heat pump must be transported and stored in the operating position (moun-
