DHW heat exchanger for gas boilers OKC 125 NTR/HV with a 1.45m2 spiral coil, enameled 1103706101

DHW heat exchanger for gas boilers – an effective solution for water heating

This domestic hot water (DHW) heat exchanger from DRAŽICE, model OKC 125 NTR/HV, is an ideal choice for heating systems with a gas boiler. Designed for installation under the boiler, it has outlets at the top, which greatly simplifies installation. Its construction allows for year-round power supply from a gas boiler, and a large coil surface area – 1.45 m² – ensures efficient heat exchange.

Construction and durability

The heat exchanger is characterized by a round shape and a solid steel construction. The lack of an electric heating element means that it is fully dependent on the operation of the gas boiler, which translates into energy savings. The internal coating of Crystal Enamel enamel provides increased resistance to corrosion, even in hard and chlorinated water. Additional protection is provided by a magnesium anode, which protects against internal corrosion. The whole is completed by modern ThermoGen4 insulation, minimizing heat loss to the environment.

Performance and application

A capacity of 125 liters makes this heat exchanger suitable for both households and public utility facilities with moderate demand for hot water. A large surface area of the spiral coil (1.45 m²) guarantees fast and efficient heating of domestic hot water. Energy efficiency class C indicates reasonable energy consumption during operation. By choosing this model, you are investing in a reliable and durable solution for preparing hot water in your heating system.
