DHW heat exchanger for heat pumps and solar collectors OKC 400 NTRR/HP SOL with two spiral coils 1.4m2 and 3.1m2, enameled 121491402

Universal domestic hot water heat exchanger for heat pump and solar collector systems

This 400-liter enameled DHW heat exchanger, equipped with two spiral coils with areas of 1.4 m² and 3.1 m², is an optimal solution for both installers and users who appreciate efficient water heating. The tank design allows connection to various heat sources, making it an extremely versatile element of the heating installation.

Construction and application

The tank is made of steel and coated with enamel, which ensures durability and corrosion resistance. Two coils – upper and lower – allow connection of a heat pump or another low-temperature heat source (e.g., solar collectors). This configuration allows for effective use of renewable energy and reduces operating costs. The possibility of installing an electric heater (TJ 6/4″ or TPK 150-8/2.2 kW) is an additional advantage, providing independence from the main heat source in emergency situations or periods of increased hot water demand. The working pressure in the tank and heat exchanger is 1 MPa, which guarantees safe and reliable system operation.

Advantages for the installer and user

• Versatility: The ability to connect various heat sources (heat pump, solar collectors, electric heater) provides flexibility in installation design.
• Efficiency: Two coils ensure optimal energy utilization and reduce water heating costs.
• Durability: The enameled coating of the tank protects against corrosion and extends the life of the device.
• Safety: Working pressure of 1 MPa guarantees safe system operation.
• Easy installation: The possibility of installing additional elements (electric heater) facilitates installation and adaptation to individual needs.
• Energy efficiency class C: Indicates a balanced energy consumption compared to other available models.

The OKC 400 NTRR/HP SOL heat exchanger is a solid solution for any home equipped with a heat pump or solar system – a reliable way to access hot water all year round.
