Solar package auroSTEP pressurized VIH S2 250/4B + VC 246/5-3 + VFK 145V 0010023561

The auroSTEP pressurized solar package is a complete solution for effectively utilizing solar energy to heat domestic hot water. The set consists of a VIH S2 250/4B tank, a VC 246/5-3 circulation pump, and two VFK 145V solar collectors. This combination ensures reliable and efficient system operation, both in residential and public utility buildings.

Efficiency and construction

The VIH S2 250/4B tank is made of stainless steel, guaranteeing high corrosion resistance and long service life. The heat exchanger made of the same material ensures efficient transfer of energy from the collectors to the water. Energy efficiency class A+ indicates high device performance, translating into lower operating costs. The system efficiency is 109.4%/100%, which means the system effectively utilizes solar energy. Compact dimensions (440 mm width, 720 mm height, and 338 mm depth) facilitate installation even in limited spaces.

Components and their role

• Tank VIH S2 250/4B: Used to store hot water heated by solar collectors. A capacity of 250 liters allows for providing hot water for a household or small facility.

• Circulation pump VC 246/5-3: Ensures circulation of the heating fluid between the collectors and the tank, enabling efficient heat transfer.

• Solar collectors VFK 145V (x2): Convert solar radiation energy into heat, which is then transferred to the tank. Two collectors increase the absorption surface of radiation and thus the efficiency of the entire system.

Advantages of the auroSTEP package

• High efficiency: Energy efficiency class A+ and efficiency at over 109% guarantee low operating costs and a quick return on investment.

• Durable construction: The use of stainless steel in the production of the tank ensures corrosion resistance and long device life.

• Complete solution: The package includes all the necessary elements to build a solar system, which simplifies installation and reduces additional costs.

• Versatile application: The system can be used in both residential and public utility buildings – wherever there is a demand for domestic hot water.

• Rated power: The rated power of the system at a temperature difference of 50-30°C is as high as 45317 kW – a solid power reserve for most households.
