Bivalent heat exchanger 200l SGW(S)B TOWER BIWAL with two spiral coils, enameled, rigid polyurethane foam, skay, vertical freestanding 26-209000

Bivalent heat exchanger – efficient domestic hot water heating

This bivalent heat exchanger with two spiral coils is a versatile solution for heating domestic hot water, allowing you to utilize various heat sources. This allows you to reduce operating costs and enjoy the comfort of hot water all year round. The design with two coils allows connection of both a heating boiler and renewable energy sources, such as solar collectors or heat pumps.

Construction and application

The SGW(S)B Tower Biwal heat exchanger with a capacity of 200 liters is a vertical, freestanding device designed for efficient domestic hot water heating. It is made of enameled steel, which ensures durability and corrosion resistance. Insulation with rigid polyurethane foam minimizes heat loss, and the skay-type housing gives it an aesthetic appearance. The device is ideal for both single-family homes and larger buildings.

Advantages and benefits

• Versatility: Possibility of connection to various heat sources (boiler, solar collectors, heat pump).
• Efficiency: Two spiral coils provide fast and efficient water heating.
• Savings: Using renewable energy sources allows you to reduce heating costs.
• Durability: Enameled tank and high-quality insulation guarantee long-term use.
• Comfort: Constant access to hot water at the right temperature thanks to the large capacity of 200 liters.
• Anti-corrosion protection: Ceramic enamel applied by the "wet" method provides protection against corrosion.
• Easy installation: Concentration of all hydraulic connections at the back of the exchanger facilitates installation.
• Standard equipment: Circulation connection and heating element as standard increase the functionality of the device.

Technical and construction parameters

The heat exchanger has two spiral coils with an area of 1 m² each (for solar collectors) and 0.7 m² (for central heating). It is equipped with two magnesium anodes (upper and lower) protecting against corrosion and a thermometer to facilitate temperature control. The maximum operating temperature of the tank is 95°C, and the heat exchanger – 110°C. The maximum working pressure of the tank is 1 MPa, and the heat exchanger – 1.6 MPa. The usable capacity of the tank is 197 liters. The energy efficiency class is B.

Additional equipment includes the possibility of mounting an insulated GE electrical kit or a titanium active anode (option). The device has a revision opening allowing access to the inside of the tank for maintenance or element replacement.
