Character

The water heater type OKC 300 NTR/SOLAR SET is equipped with only one bottom exchanger for solar collectors. The auxiliary water heating is done by electrical heating element TJ 6/4” that is possible to order among other accessories. The water heater type OKC 300 NTRR/SOLAR SET is equipped with two exchangers. The bottom one is used for solar collectors, and the top one is used for auxiliary water heating for example by gas boiler. The TJ 6/4” electrical heating element can be also mounted as an accessory.
