The products of DZ Dražice excel in long service life, high standards for insulation materials, the quality of overall production and a number of innovative technological and design solutions.
The production of heaters takes place in the Central Bohemian town of Dražice (District of Mladá Boleslav), in the premises of a plant with history that started at the turn of the 19th and 20th centuries.
Ceramic heating element
Ceramic heating element
The electric heating element is not submersed but ceramic, dry, inserted into a steel sink. Since the water heater vessel and the sink are made of one type of material (steel), there is no galvanic cell and electrochemical corrosion. Other manufacturers mostly use submersible heating elements made of other types of materials (copper, stainless steel), and thus electrochemical corrosion occurs. The system of ceramic elements withstands extremely well hard and aggressive water and significantly prolongs the life of the vessel in any conditions.
The steel vessel of the heater from a special thick sheet withstands pressure shocks. It is equipped with high-quality nickel-free enamel, which in combination with a magnesium anode protection guarantees a long service life of all Dražice water heaters. Cleansing holes allow access to the inside of the container and to remove deposits and limescale, thus saving the cost of operation.
A high-quality polyurethane insulation ensures low heat losses and low operating costs.
