Boiler Dražice OKC 160/1 m² is a vertically installed two-system boiler with a power of 2000 W. Heat exchanger area: 1 m². Volume 120 l. Dimensions: 1255 x 524 mm. Energy efficiency class C. The ceramic heater of the dual system boiler is not in direct contact with water and does not scale. Therefore, a dual system boiler is considered maintenance free. Dražice is the No. 1 boiler company in the Czech Republic, whose production is well known throughout Europe. The company exports its products to nearly twenty countries around the world. The main advantage of Dražice production, in addition to top quality, quality materials and a controlled production process, is the unique heating element system. The electrical element is not submersible but is dry, ceramic and housed in a steel sleeve. Since both the heating element and the boiler body (tank) are made of the same material (steel), no galvanic and electrolytic corrosion occurs between them. Other manufacturers mainly use submersible heaters made of different materials (copper, stainless steel) and therefore cause (electrochemical) corrosion. The system of ceramic elements is particularly resistant to hard and corrosive water and significantly extends the service life of the tank in all conditions. Internal cleaning of the tank is ensured through cleaning openings, which allows to remove sediment and limescale, which increases operating costs. For general corrosion protection, a magnesium anode is used, which prolongs the service life of the tank by improving the already high performance value that you acquire when you buy a boiler made by DZ Dražice.
