The Parasol water heating system uses the solar energy
for the outdoor pool heating and constitutes a 100% green
and sustainable solution. It is very economical since no
heat exchangers are required and the swimming pool
water ows through the collectors and is heated directly.
This attractive system offers durable savings combined
with increased quality of life. The design is inspired by
the form of the sun. Just like the contours of the sun but
also with a perfectly calculated inclination angle, so that
each sunbeam is captured, independent of its inclination
angle. A southerly facing aspect is therefore not necessary.
Investing in Parasol is not only a life choice, but also an
ecological and positive contribution to the environment.
Pools can be used for the extended period of March November or even longer, depending on the hours of the
solar irradiation. Parasol offers you the ideal solution for an
enjoyable “summer” the whole year round.
Warmth in practice
Manufactured out of high quality recyclable plastic, it is protected against frost and storm. Furthermore, it is black, to
maximise heat absorption and warmth retention. Firstly, due to the isolating effect of the double wall hood from which
the rain water simply ows away keeping it from the warmed water inside the collectors. An effective distribution
system takes care of the rest. The quick circulating water ensures that fast cooling is averted. Owing to this feature,
the water temperature increases in the Spring and in the Autumn on a sunny day by an average of 3°C per day and
throughout the whole swimming season by a minimum of at least 6 - 7°C.

INSTALLATION OF COLLECTORS
The collectors should preferably be tted horizontally. The possible scenarios for installation of the collectors are:
y Flat roof of a shed, garage, technical area, etc.
y Sloped roof no more than 35°, faced to the South / East
y Pavement
y Lawn
y Open pergola
y Parasol stand
During the tting of the collectors, you have to take into consideration the following aspects:
y Possible shading by nearby buildings, trees, etc.
y The distance between the technical area (swimming pool) and the collector
y Collector temperature sensor
y Possible wind sensibility
y Use ground liner if placed directly on the ground
Shading
The collectors must be positioned so that they catch direct sunlight throughout the day. If this proves to be problematic
due to circumstances, nd an area with the most sunshine hours, preferably between 11.00 h and 16.00 h in general
shading has considerable negative inuence on the systems performance.
Collector’s temperature sensor
The collector must be positioned so that the temperature sensor is faced to the South / East.
Sensibility to the wind
As the collectors are not sensitive to the wind, you can place these without further measures or restraints.

Exceptions:
y Tiled roofs. Because roof tiles can come of under stormy conditions, we do not recommend placing the collectors
on tiled roofs without tighten them.
y Open pergolas. If chosen to place the collectors on an open pergola keep in mind that winds can blow hard from
beneath. Tighten the collector on the wooden or metal beams using stainless steel screws.

Ground fabric liner.
If the collectors are placed on an untreated surface it is
advisable to use fabric liner underneath the collector.
HOW TO FIX THE COLLECTOR´S TEMPERATURE SENSOR
HOW TO CONNECT THE COLLECTORS
Connect the special PE T-connection including
the stainless steal holder, designed for the (small)
temperature sensor, on the collectors return tube as
close as possible underneath the collector. (1)
The collectors need to be connected with PE tubes
(heavy duty tubes). Don’t use PVC tubes for they are
not ultra violet resistant. Best is to connect through
PE sockets. The supply-tube needs to be connected
to the right side and the return-tube to the left side.
