DRAŽICE OKC 80 combined water heater 73 l, 2.2 kW, vertical
DRAŽICE OKC 80 combined water heater 73 l, 2.2 kW, vertical
DRAŽICE OKC 80 is a vertical combined storage water heater that combines electric water heating with heating from an external heat source. The model is designed for wall mounting and is suitable for domestic hot water preparation in residential buildings and heating systems.
The water heater is equipped with a 2.2 kW ceramic electric heating element and one integrated heat exchanger. The heat exchanger surface area is 0.41 m² and its volume is 1.8 litres, allowing the water to be heated by a boiler or another external heating water source.
The heat exchanger can operate in both forced-circulation and gravity heating systems. The maximum heating water temperature in the heat exchanger is 110 °C and the maximum operating pressure is 10 bar.
In electric heating mode, the heating time from 10 to 60 °C is approximately 1.9 hours. When using the heat exchanger, the heating time from 10 to 60 °C is approximately 50 minutes under the manufacturer's specified test conditions.
The actual storage capacity of the DRAŽICE OKC 80 is 73 litres. The maximum water temperature in the tank is 80 °C and the maximum operating pressure is 6 bar. The electrical protection rating is IP44.
High-quality thermal insulation helps minimise unnecessary heat losses and retain hot water temperature. The OKC 80 has energy efficiency class C, while its mixed water volume V40 is 138.7 litres.
