SOLAR WATER HEATERS
GENERAL INSTALLATION RULES
ATTENTION!
Installation must be in compliance with local & national rules concerning water and electrical
installations (plumbing, electricity, hygiene, urban and others).
The solar system’s packaging must be removed at the site of installation in order to protect the device from shocks
during its transportation, making sure that the collectors are not supported on their pipe joints. Until installation is
completed, the collector’s glass must remain covered until the water storage tank is filled with domestic water, so as
to avoid the boiling of the filling liquid or the breaking of the glass. The plastic protective caps must be removed from
the water storage tank’s and the collectors’ pipe joints.
Installation location - shading:
Prior to installation, a proper selection of the location must be made by the installer
(in agreement with the customer), and the surface must be checked (taking into consideration its static resistance),
so that it can bear the weight of the system.
On inclined roofs the system should not be placed between two beams but above a single one.
The position chosen for the solar water heater installation should not be shaded by any obstacles such as trees,
buildings and other all year round, so as to ensure at least 4 hours of uninhibited exposure of the collector to the sun
during the midday hours.
LATITUDE DISTANCE BETWEEN THE OBSTACLE AND THE COLLECTOR (L)
0° - 25° 1.0 x H
26° - 35° 1.5 x H
36° - 45° 2.0 x H
46° - 50° 2.5 x H

Any deviation means a reduction in the system’s performance. If a deviation from the proper orientation cannot
be avoided, then the system’s performance should be corrected by increasing the collector surface, following a
study and evaluation of the specific conditions that apply. As the sun ray’s angle of attack varies with time but also
depending on the system’s location, the collector’s angle should be approximately equal to the installation location’s
latitude. At this angle the maximum energy gain on an annual basis is achieved.
Installation particularities:
In case there is no compatibility between the surface where the solar water heater will be
installed (inclined or flat) and the standard equipment provided with the system, a different kind of equipment should
be used. The responsibility for the equipment chosen lies on the installer and in no case on the company. It is up to
the installer to propose & install the different equipment required, who must previously agree it with the customer.
Special weather conditions: In regions suffering from heavy snowfalls, please make sure that the snow is always
timely removed. For this case and cases of regions with storms, high wind velocity, rainfall, cyclones, tornadoes, the
system must be placed on the roof as firmly as possible and must be tightened with extra metal stripes. In areas
where these conditions occur and hail of more than 20mm in diameter is to be observed, it is recommended that
insurance for the solar water heater is issued. In every case, it is recommended to secure your solar water heater on
the support base system.

Orientation - optimum angle: a basic factor for the system’s optimum
performance is the selection of its angle and orientation for its particular
location and the time during which the maximum gain is required.
The solar system should be positioned so that the collector’s surface
faces the geographical south, if the installation takes place in the
Northern Hemisphere (and the geographical north for the Southern
Hemisphere), i.e. it should always face the Equator.
