Dražice OKC NTR and OKC NTRR are designed to be placed on the ground in the technical room, with hot water being prepared using an existing high temperature heating source such as a gas or wood chip boiler. This is achieved by means of a heat exchanger built into the boiler. Boilers with a single heat exchanger are available in volumes from 100 to 250 litres.

Dražice NTRR - vertical stationary boiler with two heat exchangers (only one heat exchanger is installed in the NTR series), allowing an existing heating source to be connected in parallel. Boilers with two heat exchangers are only available in 200 and 250L volumes.
