Product detailed description
Indirect stationary hot water heater/boiler Dražice OKC 300 NTR/BP for water heating
Possibility of additional installation of a heating flange type TPK 168 - 8 and for volumes 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 storage tank for boilers over 24 kW.
A newer line of enamelled indirect water heaters for floor standing installation with volumes of 100–300 liters, featuring an enamelled tank and a powerful single heat exchanger, or from the 200-liter 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 an output of 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, 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 the possible insertion of an auxiliary electric heater of the TPK series from the accessories. For using the heater in a solar system, heaters over 200 liters are equipped with a 6/4" connection located above the solar heat exchanger for the electric heating unit TJ from the accessories section.
