DHW heat exchanger SGWS NEPTUN2 Kombi Elektronik 140L NEW right-hand, spiral coil, electric heating element, polyurethane foam, metal jacket, LED display, wall-mounted 06-144770

Domestic hot water heat exchanger – a reliable source of comfort

The SGWS NEPTUN2 Kombi Elektronik DHW heat exchanger is a versatile solution for water heating, combining efficiency with user convenience. This wall-mounted heat exchanger with a capacity of 140 liters, equipped with a spiral coil, ensures quick and efficient water heating both through cooperation with a central heating boiler and with an electric heating element. The coil design on the right side facilitates integration with existing installations.

Construction and application

The Neptun2 Kombi heat exchanger is distinguished by its compact dimensions – a diameter of only 48 cm means it will easily fit even in small boiler rooms. The universality is confirmed by the possibility of choosing the capacity (from 80 to 140 liters), which allows it to be adapted to the individual needs of household members. The spiral coil with a large surface area ensures rapid heat absorption from the central heating boiler, and high-quality polyurethane foam insulation minimizes heat loss, reducing operating costs. A durable metal casing guarantees longevity and corrosion resistance, and a special EXTRA GLASS ceramic enamel ensures hygienic use.

Key features and benefits

• Versatility: Possibility of heating water with a central heating boiler and an electric heating element – an ideal solution for both single- and dual-function installations.
• Fast heating: The spiral coil with a large surface area ensures efficient heat absorption and quick access to hot water.
• Energy saving: A thick layer of polyurethane foam minimizes heat loss, reducing operating costs and environmental impact.
• Durability: Made of steel with EXTRA GLASS ceramic enamel and equipped with a magnesium anode – protection against corrosion and long device life.
• Comfort of use: Equipped with an LED display for easy reading of operating parameters and an electronic controller for precise temperature control (in the Elektronik version).
• Compact dimensions: A diameter of 48 cm allows for installation in a limited boiler room space.
• Energy efficiency class C: Provides reasonable energy consumption while delivering thermal comfort.

Additionally, the heat exchanger has anti-corrosion protection and the possibility of using an active titanium anode (optional), which extends its lifespan and minimizes the need for servicing. This makes it an investment for years to come, guaranteeing a reliable source of hot water for the whole family.
