System Description
The FREE HOT WATER solar water heating system is a closed-loop active solar system which, when installed with a
suitable auxiliary heat source, can act as the primary source of domestic hot water for residential use. The system
components provided with the FREE HOT WATER solar water heating system include the solar collectors, collector
flashings, solar loop pipe and fittings, solar storage tank, solar pump station and controller, temperature sensors,
expansion tank, air separator, mixing valve, and non-toxic propylene glycol heat transfer fluid. The solar collector is
the engine of the FREE HOT WATER solar water heating system.
When the sun is shining, the heat energy is absorbed by the solar collector and transferred to the heat transfer fluid
circulating through the solar collectors. The system pump efficiently circulates this heated fluid through the
collector’s piping and the heat exchanger located in the solar storage tank. As the heat transfer fluid passes through
the heat exchanger, the heat in the fluid is transferred by conduction to the potable water in your solar storage tank
causing the temperature in the tank to rise. This process continues as long as the sun is shining or until the
temperature in the solar storage tanks reaches its maximum temperature set point.
General Instructions
Installation must only be carried out by qualified personnel. The entire information in these instructions is intended
exclusively for such qualified personnel. Only the supplied material should be used for the installation. Prior to starting
installation and operation of the solar collector system, please inform yourself about the applicable local standards and
regulations. The use of a carrying strap is recommended for transporting the collector. The collector must not be lifted
at the connections or on the threading. Avoid impacts and mechanical influences on the collector, in particular on the
solar glass, the rear panel and pipe connections.
The collectors may only be mounted on sufficiently load-bearing roof surfaces and substructures. It is imperative that
the static load bearing capacity of the roof or substructure is checked in terms of local and regional conditions prior to
installation of the collectors by the customer, if necessary through the involvement of a structural engineer.
Particular attention should be paid to the quality of the (timber) substructure in terms of the stability of the screw
connections necessary for fastening the collectors.
Specifications
The FREE HOT WATER solar water heating system is designed to produce domestic hot water from either solar
collector, an electrical or gas backup, or a boiler back up (provided by others). The FREE HOT WATER systems can
also be used as a solar preheat system to conventional electric or gas water heaters (provided by others).
Collectors and flashings
FREE HOT WATER solar collectors and flashings allow for a low profile, roof integrated, solar panel installation. The
FREE HOT WATER collector is made up of copper tubes and a plate that is covered with a highly selective absorber
coating; this assembly is enclosed in a well insulated aluminum frame or “box” and covered with low-iron tempered
glass glazing. FREE HOT WATER solar water heating systems are available for integration onto either shingle or tile
roofs. The collector is suitable for angles between 15° (minimum) and 75° (maximum). The collector connections
and the ventilation openings must be protected against the penetration of water as well as against contamination
through dust etc.
