Product detailed description
Indirect heating water heater, stationary boiler Dražice OKCE 250 NTRR/2,2 kW for water heating
Built-in heating element in flange 2.2 kW
For volumes of 200, 250, 300 liters, possibility of additional installation of a TJ G 6/4" heating unit. On order
Most common use:
Year-round DHW heating with heating water from a gas boiler for connection with priority DHW heating or combined operation with heating water and electric energy. From the OKC 200 NTRR volume onwards, it is possible to combine a gas boiler, an alternative energy source or a solar system. By connecting both heat exchangers in series, we can obtain an indirect heating tank for boilers over 24 kW in combination with electric energy.
A newer range of enameled indirect heating water heaters for floor standing installation in volumes of 100–300 liters with an enameled 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 various 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, a circulation outlet, and up to 200 liters a safety valve.
In the lower part of the water heater there is an inspection flange opening for cleaning the inside of the tank with an installed auxiliary electric heater. When using the water heater for a solar system, water heaters over 200 liters have a 6/4" port available, located above the solar heat exchanger for the electric heating unit TJ from the accessories.
