Solar set 1 x SR 22 vacuum tube collector without storage tank

Solar set with SR 22 WEBER vacuum tube solar collector without DHW cylinder

SOLAR KEYMARK certified to take advantage of subsidy programmes!

GENERAL INFORMATION

High-quality solar set with 1 solar tube-vacuum collector SR 22 by WEBER. The set does not include a DHW cylinder. It is recommended to equip the set with a DHW cylinder with a capacity of up to 100 litres.

The assumed collector area provides efficient water heating of approximately 60% of the annual demand. The remaining 40% should be provided by a central heating boiler connected to the upper cylinder coil or by an electric heater.

Installation fluid

The solar fluid is produced on the basis of propylene glycol, which means that it is completely safe for health in the event of any leakage into the drinking water. The fluid is hygienically certified by the National Institute of Hygiene, which is an additional guarantee of a high level of safety. The fluid is supplied in a 10-litre container as a concentrate with a freezing point below -64°C. After dilution with water, up to 30 litres of ready-to-use mixture is obtained, which is sufficient for typical installations.

Solar expansion vessel (expansion tank) 18 l

Despite appearances, the diaphragm vessel is one of the most important components of a solar installation. The selection of a vessel with an operating temperature that is too low or an operating pressure that is too low can lead to frequent operating problems.

The maximum operating temperature of the diaphragm vessel included in the kit is 120°C, and the permissible operating pressure is as much as 10 bar, which guarantees high stability of the entire system.

Connection kit

The kit is equipped with a system of brass compression fittings to enable efficient and secure connection of the collector to the pipes.

• 1 x Compression elbow with ¾" socket connection for efficient connection to corrugated stainless steel pipes
• 1 x compression cross-connection with ¾" GZ connection for efficient connection to corrugated stainless steel pipes. The connector is equipped with a vent for easy filling and with an immersion sleeve for the temperature sensor of the controller.
