DHW heat exchanger for gas boilers OKC 200 NTRR with two spiral heat exchangers, enameled 1107908101

Domestic hot water heat exchanger for gas boilers

This 200-liter DHW heat exchanger OKC 200 NTRR is a solid solution for year-round hot water supply, working with a gas boiler. The design without an electric heating element makes it an efficient and economical solution, especially in installations with access to gas. The tank made of steel is coated with high-quality Crystal Enamel enamel, which ensures corrosion resistance, even in hard or chlorinated water.

Two heat sources and high efficiency

The heat exchanger is distinguished by two spiral coils with a large heat exchange surface – upper (1 m²) and lower (1 m²). This solution allows connection to two independent heat sources, which increases flexibility and allows for optimization of heating costs. Modern ThermoGen4 insulation minimizes heat loss to the environment, which translates into lower energy bills.

• Two coils: possibility of connecting two heat sources – e.g. gas boiler and heat pump or solar collectors.
• Crystal Enamel enamel: increased resistance to corrosion and scale, extending the life of the device.
• Magnesium anode: additional protection against corrosion, ensuring long-term reliability.
• ThermoGen4 insulation: minimal heat loss and energy savings.
• Steel tank: durable construction guaranteeing long service life.
• Energy efficiency class C: provides a reasonable balance between performance and energy consumption.

The design of the heat exchanger has been designed with ease of installation and servicing by professionals in mind, but the intuitive operation also makes it a good choice for end customers looking for a reliable source of domestic hot water.
