Solar set solar collector 2 x WEBER SOL ECO 2.5 without storage tank

Solar set with 2 WEBER SOL ECO 2.5 solar collectors - without hot water storage tank

RELEVANT INFORMATION

High-quality solar set with 2 solar collectors of WEBER SOL ECO 2.5 brand. The set does not include a hot water storage tank.

The adopted collector area provides efficient water heating at about 50% of the annual demand. The remaining 50% (winter period) is to be provided using a central heating boiler connected to the upper cylinder coil or using 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 diluting 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 system. The selection of a vessel with too low an allowable operating temperature or too low an allowable pressure can cause frequent operating problems.

The maximum operating temperature of the diaphragm vessel included in the set is 120 °C, while the allowable operating pressure is as high as 10 bar, which is a guarantee of high stability of operation of the entire system.

Connection kit

The kit is equipped with a system of brass compression fittings that allow the collectors to be efficiently and securely connected to each other, as well as to connect to piping.
The set includes:

• 4 x Double clamp couplers for connecting two adjacent collectors together
• 2 x Compression plugs for blinding two diagonal collector stubs
• 1 x Compression elbow with ¾" GZ connection for efficient connection with stainless steel corrugated pipes
• 1 x Compression cross coupling with GZ ¾" connection enabling efficient connection to corrugated stainless steel pipes
  
  

NOTES: In order to complete the installation of the solar set, it is necessary to obtain, among other things, a mounting kit for the collector, solar piping and installation fittings necessary to connect the tank to the existing system. The mounting kit is not included as standard, due to the need to adapt it each time to the type of roofing and roof slope. All these products can be purchased in our online store.
