Boiler Drazice OKC500NTRR/SOL

The Hewalex OKC500NTRR/SOL capacitive water heater is designed for heating hot domestic water in two systems: a solar installation and a boiler.

Brief information

The Hewalex OKC500NTRR/SOL water heater comes with two heat exchangers (coils). The lower coil is connected to the solar system, while the upper coil is used for a traditional heat source, most often a boiler. An electric heater (TEN), installed in a separate 6/4" pipe, can be used as an additional heat source.

The water heater (boiler) features low heat loss thanks to 50 mm thick rigid polyurethane foam insulation. Energy efficiency class C indicates a very high standard in its class, while maintaining optimal
