DHW heat exchanger with spiral coil, freestanding SGW(S) Tower Grand 300L, polyurethane, skay, coil area 2.7m² 26-308107N

Heat pump water heater – efficient domestic hot water heating

The Tower Grand standing DHW heat exchanger with a spiral coil is a solution designed to work with heat pumps, providing fast and efficient domestic hot water heating. The design with an enlarged coil with an area of 2.7 m² makes it an optimal choice for both on-off and inverter heat pump installations. This is a device that combines performance, durability and comfort.

Design and application

The Tower Grand heat exchanger has been designed for maximum heat exchange efficiency. The spiral coil, extending along the entire height of the tank, ensures even heat distribution and rapid water heating. A capacity of 300 liters makes it an ideal solution for households with varying hot water demands. The possibility of installing an electric kit as an additional heat source increases the flexibility of use and allows the device to be adapted to individual needs.

Advantages and benefits

• High efficiency: Enlarged coil (2.7 m²) ensures rapid water heating and high heat exchange power (64kW at 80/10/45°C).
• Versatility: Compatible with both on-off and inverter heat pumps.
• Durability: Made of steel with EXTRA GLASS® ceramic enamel, which creates a durable protective barrier against corrosion.
• Anti-corrosion protection: Two magnesium anodes further protect the tank against corrosion, extending its lifespan.
• Thermal insulation: A thick layer of polyurethane foam and skay covering minimize heat loss and reduce operating costs.
• Easy installation and maintenance: Hydraulic connections located at the rear of the device facilitate installation and access to elements requiring servicing.
• Warranty: 5-year warranty provides peace of mind and investment security.
• Expandability: The option of installing an electric kit allows the use of an additional heat source if necessary.

Construction features

The tank of the heat exchanger is made of steel coated with EXTRA GLASS® ceramic enamel, which ensures high corrosion resistance and long-term operation. Two magnesium anodes provide additional protection against corrosion. Insulation with polyurethane foam and skay covering minimize heat loss, and adjustable leveling feet ensure the stability of the device during use. The design has been created to ensure convenient installation and easy access to elements requiring servicing – hydraulic connections are located at the rear of the device and sensor covers facilitate integration with the heat pump.

Compliance and standards

The Tower Grand heat exchanger meets all required safety and quality standards, confirming its reliability and durability. Energy efficiency class B guarantees economical energy consumption during device operation.
