Dražice OKC combination water heaters are a compact solution that can provide hot water using a built-in electric heating element or by connecting it to your existing heating system. The OKC combi boiler is designed for vertical wall mounting using the supplied fixing elements.

The combination boiler provides hot water via an integrated heat exchanger which is connected to the heating system. The main difference between this and the standard OKC combi boiler is that the built-in heat exchanger is larger (1 m2 compared to 0.7 m2), which reduces hot water preparation time by up to a factor of two.As a secondary heat source, which enables hot water to be prepared independently of the heating source, there is a built-in single-phase electric heating element with a capacity of 2.2 kW. The desired hot water temperature can be controlled via a thermostat built into the tank body.

The tanks themselves are made of steel and have an enamelled coating on the inside. The tanks are available in different capacities depending on your hot water consumption and the size of the boiler room, from 80 to 200L.
