Storage water heater DRAZICE OKC 200 NTR/HP with spiral heat exchanger 2.1 m², capacity 208 L, enamelled
DRAZICE OKC 200 NTR/HP is an enamelled storage water heater with an integrated spiral heat exchanger offering a net capacity of 208 litres. The unit is intended for domestic hot water (DHW) preparation when connected to external heat sources such as solar collectors or external boilers. The enamel coating protects the storage vessel from corrosion while the 2.1 m² spiral heat exchanger provides efficient heat transfer, enabling large-volume hot water storage for residential applications.
The enamelled interior reduces the risk of corrosion and extends the service life of the tank. The built-in spiral heat exchanger with a surface area of 2.1 m² ensures effective transfer of heat from an external source into the stored water. With a 208 L net capacity, the heater supplies sufficient domestic hot water for family homes and small apartment units. The design supports connection to various external heat sources, including solar thermal systems and boilers, allowing flexible system integration.
Install the DRAZICE OKC 200 NTR/HP according to local regulations and the manufacturer’s installation instructions, ensuring correct hydraulic and safety connections to the external heat source. Connect the spiral heat exchanger circuit to the external boiler or solar collector loop, and the potable water inlet and outlet to the building plumbing. Commission the system by filling the tank, venting air from the exchanger and piping, and checking all connections for leaks. Set and monitor operating temperatures on the external heat source and any control devices used in the heating loop.
Use corrosion-inhibiting anode protection if recommended by the installation manual, maintain regular checks of connections and insulation, and schedule periodic inspections to verify exchanger performance and tank integrity. Match the heat source capacity and control settings to the 2.1 m² spiral exchanger to achieve optimal charging times and energy efficiency.
