Product detailed description
Indirect-heated stationary water heater, boiler Dražice OKC 200 NTR/BP for water heating
Possibility of additional installation of a heating flange type TPK 168 - 8 and for volumes of 200, 250, 300 litres 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 floor-standing water heaters in volumes of 100–300 litres with an enamelled tank and a powerful single heat exchanger, or from the 200-litre 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 obtain a DHW source with an output of up to 57 kW. The water 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 water heater there is an inspection flange opening for cleaning the inside of the tank and possible insertion of an auxiliary electric heating element of the TPK series from the accessories. For using the water heater in a solar system, water heaters over 200 litres have a 6/4" port available, located above the solar heat exchanger, for the electric heating unit TJ from the accessories section.
