Product detailed description
Indirect-heated stationary water heater, boiler Dražice OKC 500 NTRR/BP for water heating
Possibility of additional installation of a heating flange type TPK 168 - 8 and for volumes of 200, 250, 300 liters a threaded body TJ G 6/4"
Most common use:
Year-round DHW heating with 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-heated storage tank for boilers over 24 kW.
A newer range of enamelled indirect-heated water heaters for floor standing installation in volumes of 100–300 liters with an enamelled tank and a powerful single heat exchanger, or from the 200 liter type with two heat exchangers for DHW heating from an external source or a combination of different sources. By connecting both heat exchangers in series, we can achieve a DHW source with an output of up to 57 kW. The heater is equipped with DHW temperature regulation (thermostat for controlling a three-way valve or circulation pump) for a voltage of 230 V/50 Hz, up to 200 liters 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 installation of an auxiliary electric heating element of the TPK series from the accessories. For using the heater in a solar system, heaters over 200 liters have a 6/4" port available, located above the solar heat exchanger for the TJ electric heating unit from the accessories section.
