Product detailed description
Stationary indirect water heater, boiler Dražice OKC 250 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 indirect storage tank for boilers over 24 kW.
Indirect water heaters for floor standing installation 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 version with two heat exchangers for connecting two heating water sources (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 obtained. 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 an outlet for circulation.
