Solar set 3 x SR 22 vacuum tube collector with 400 l storage tank

Solar set with 3 HP 22 tubular-vacuum solar collectors + hot water storage tank. 400 l.

SOLAR KEYMARK certified to take advantage of subsidy programs!

RELEVANT INFORMATION

High-quality solar set with a 400-liter hot water storage tank and 3 SR 22 vacuum tube solar collectors included.

The adopted collector area provides efficient water heating at about 50% of the annual demand. The remaining 50% (winter period) should be provided by using a central heating (central heating) boiler, which is connected to the upper coil of the storage tank, or with the help 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 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. Selection of a vessel with too low allowable operating temperature or too low allowable pressure can cause frequent problems in use.

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

Set of connectors

The set is equipped with a system of brass compression connectors that allow the collectors to be efficiently and securely connected to each other, as well as to be connected to pipes.

The set includes:

• 2 x clamping couplings for connecting two adjacent collectors together
• 1 x Compression elbow with a GZ ¾" connection enabling efficient connection to corrugated stainless steel pipes
• 1 x compression cross coupling with a 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, piping and installation fittings necessary to connect the tank to the existing installation. The mounting kit is not included as standard, due to the need to adjust it each time to the type of roofing and roof pitch. All these products can be purchased in our online store.
