Bivalent heat exchanger 700L SGW(S)B TOWER BIWAL with two coils, enameled, demountable soft polyurethane foam 100mm, skay 26-709600N

Bivalent DHW heat exchanger – efficient use of multiple heat sources

The SGW(S)B Big Tower Biwal 700 DHW heat exchanger is an advanced solution for heating domestic hot water, designed to work with various heat sources – both conventional and renewable. Equipped with two spiral coils with a large surface area, it allows for efficient use of energy from the central heating boiler and solar collectors, which translates into lower operating costs and greater energy independence. A tank with a capacity of 700 liters is suitable for both single-family homes and multi-family buildings or public utility facilities.

Construction and application

The heart of the heat exchanger is an enameled tank, which ensures durability and corrosion resistance. Two spiral coils with a large heat exchange surface guarantee fast and efficient water heating. A removable thermal insulation with a thickness of 100 mm minimizes heat loss, and the outer casing made of skay provides an aesthetic appearance and additional protection. The possibility of installing an additional electric kit expands the functionality of the device, allowing water to be heated in emergency situations or during periods of low efficiency of other heat sources.

Advantages and benefits

• Versatility: Possibility of powering from a central heating boiler, solar collectors and an electric heater (optional).
• High efficiency: Two spiral coils provide a large heat exchange surface and fast water heating.
• Energy saving: Removable thermal insulation minimizes heat loss, reducing operating costs.
• Durability: The enameled tank ensures corrosion resistance and long device life.
• Easy installation and maintenance: The design of the heat exchanger allows easy access to elements requiring maintenance or replacement.
• Aesthetic appearance: The skay casing gives the device an elegant look that blends well with various interior styles.
• Anti-corrosion protection: The EXTRA GLASS enamel used guarantees safe use for a long time.
• Large capacity: 700 liters is an optimal choice for families with greater needs for domestic hot water.

It is worth remembering that the SGW(S)B Big Tower Biwal 700 heat exchanger is an investment in thermal comfort and savings on energy bills. Its versatility and high quality of workmanship make it an ideal solution for both installers looking for reliable equipment for their clients, and for end users who want to enjoy hot water all year round.
