Product detailed description
Indirect-fired stationary water heater, boiler tank Dražice OKC 300 NTRR/BP for water heating
Possibility of additional installation of a TPK 168 - 8 type heating flange, and for volumes of 200, 250, 300 litres a TJ G 6/4" threaded body
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-fired storage tank for boilers over 24 kW.
A newer range of enamelled indirect-fired heaters for floor standing installation with volumes of 100–300 litres, featuring an enamelled tank and a powerful single heat exchanger, or from the 200-litre type onwards two heat exchangers for DHW heating from an external source or a combination of different sources. By connecting both heat exchangers in series, a DHW source with output up to 57 kW can be achieved. The heater is equipped with DHW temperature control (thermostat for controlling a three-way valve or circulation pump) for 230 V/50 Hz voltage, up to 200 litres a safety valve, and a circulation outlet.
In the lower part of the heater there is an inspection flange opening for cleaning the inside of the tank and for possible insertion of an auxiliary electric heating element of the TPK range from the accessories. For using the heater in a solar system, heaters over 200 litres have a 6/4" socket available, located above the solar heat exchanger, for the TJ electric heating unit from the accessories section.
