The stationary vertical water heater Dražice OKC NTRR/BP is designed for installation on the ground in the technical room. Unlike other Dražice hot water heater models, the NTRR/BP boilers are equipped with a side flange through which the unit can be cleaned.

Hot water is heated using the existing boiler and built-in heat exchanger, but a flange-mounted heating element for the BP series can be installed as an additional heating source, with a heating capacity of 2.2 kW or 5-9 kW. The NTRR series boilers are equipped with two heat exchangers for connecting an additional heating source or for interconnecting heat exchangers, allowing the boiler to be used with low-temperature heating sources.

The NTRR/BP series is available in different volumes depending on the hot water consumption, from 200 to 500L.
