Solar set 2 x HP 30 vacuum tube collector without storage tank

Solar set with two HP 30 WEBER vacuum tube solar collectors without hot water storage tank.

High-quality solar set with 2 HP 30 tubular-vacuum solar collectors by WEBER. The set does not include a hot water storage tank. It is recommended to equip the set with a DHW tank with a capacity of up to 400 liters.

The adopted collector area provides efficient water heating at about 60% of the annual demand. The remaining 40% should be provided by a central heating boiler connected to the upper coil of the tank 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 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.

Connection kit

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

• 1 x Compression elbow with GZ ¾" connection for efficient connection to stainless steel corrugated pipes
• 1 x Compression cross connector with GZ ¾" connection allowing 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
• 1 x double clamp fi 22

NOTES: In order to complete the installation of the solar kit, it is necessary to obtain, among other things, a mounting kit for solar systems, 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 for each time to adjust it to the type of roofing and roof slope. All products can be purchased from our online wholesaler.
