DRAŽICE OKC 200 NTR/HP indirect water heater for heat pumps, 208 l, 2.0 m² heat exchanger

DRAŽICE OKC 200 NTR/HP is a floor-standing indirect hot water storage tank specifically designed for use with heat pumps and other low-temperature heat sources. The actual storage capacity is 208 litres.

The model is equipped with one large heat exchanger with a heat transfer surface of 2.0 m² and a volume of 13.3 litres. The large heat exchanger surface is suitable for efficient heat transfer from a heat pump or another low-temperature heating source.

DRAŽICE OKC 200 NTR/HP is designed for year-round domestic hot water preparation using heating water supplied by a heat pump. The maximum operating temperature of the heat exchanger is 110 °C, while the maximum operating pressure in both the tank and heat exchanger is 10 bar.

The heating time via the heat exchanger from 10 to 50 °C is 34 minutes under the manufacturer's specified test conditions. The maximum hot water temperature in the tank is 80 °C.

The design allows the installation of a TJ 6/4" electric heating unit, making it possible to supplement heat-pump water heating with electric heating when required.

A review flange opening is located at the bottom of the water heater, providing access to the inside of the storage tank for cleaning and maintenance. The OKC 200 NTR/HP has energy efficiency class C and a static heat loss of 82 W.
