GENERAL INFORMATION

High-quality solar set with 1 solar collector of WEBER SOL ECO 2.85 brand. The set does not include a hot water storage tank.

Adopted collector area provides efficient heating of water at about 40% of annual demand. The remaining 60% (winter period) should be provided using central heating boilers, which are connected to the upper coil of the storage tank or by means of 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 case of possible leakage into the domestic water. The fluid is hygienically certified by the National Institute of Hygiene, which is an additional guarantee of a high level of safety. The liquid is supplied in a 10-liter container in the form of a concentrate with a freezing point lower than -64 °C. After dilution with water, up to 30 l. of ready-to-use mixture is obtained, which is sufficient for typical installations.

Diaphragm vessel (expansion tank), solar 18 l.

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

The maximum working temperature of the diaphragm vessel included in the kit is 120 °C, while the allowable working pressure is as high as 10 bar, which guarantees high stability of operation of the entire system.

Connection set

The kit is equipped with a system of brass compression fittings that allow efficient and secure connection of collectors with each other and connection with pipes.

The kit includes:

    2 x Compression plugs for blinding two diagonal stubs of collectors
    1 x Compression elbow with GZ ¾" connection for efficient connection to corrugated stainless steel pipes
    1 x Crimp cross coupling with GZ ¾" connection enabling efficient connection with corrugated stainless steel pipes

REMARKS: In order to complete installation of the solar set, it is necessary to obtain, among others, a mounting kit for solar systems, solar piping and installation fittings necessary to connect the tank to the existing installation. The installation kit is not included as standard with ze
