Product detailed description
Indirectly heated stationary water heater Dražice OKC 200 NTRR for water heating
Without side flange
Most common use:
Year-round DHW heating using heating water from a gas boiler for connection with priority DHW heating. For the OKC x NTRR type, a combination of a gas boiler and an alternative energy source is possible, or when connecting both heat exchangers in series, an indirectly heated storage tank for boilers over 24 kW.
Indirectly heated floor-standing water heaters in volumes of 100–250 liters with an enamelled tank and a powerful heat exchanger for heating domestic hot water (DHW) from an external source. The 200-liter and 250-liter volumes are manufactured in a variant with two heat exchangers for connecting two sources of heating water (e.g. gas boiler + alternative source). By connecting both heat exchangers in series, a DHW source with an output of up to 44 kW can be achieved. The water heater is equipped with DHW heating temperature control (thermostat for controlling a three-way valve or circulation pump) for a voltage of 230 V/50 Hz, a safety valve and a circulation outlet.
