Drazice boiler

Drazice domestic hot water tank with two heat exchangers, without electric heating insert 200 liters
5 years with a guarantee!
OKC NTRR storage tanks are mainly used as storage systems for domestic hot water solar collector systems can be used.
The solar collectors must be connected to the lower and the boiler to the upper heat exchanger.
The containers are welded, made of sheet steel, their internal surface protection is fire enamel coating.
Their thermal insulation 60 mm thick hard polyurethane insulating foam foamed directly on the tank body.
Additional surface protection is provided by a magnesium anode screwed in from above.
There is also a 6/4" socket at approximately mid-height on the containers, through which an electric heating cartridge can be built on.
