Technical Parameters

About the Manufacturer

This is the most famous water heater factory in the Czech Republic, with a tradition spanning more than forty years. The company produces 20, 50, 80, 100, 125, 160, 180, 200, 250, 300, 400, 500, 750, and 1000-liter vertical, horizontal, electric, combined, and stationary water heaters. A high level of technology and polyurethane thermal insulation guarantees low heat loss and economical operation. Environmentally friendly powder coatings on the external heater shell minimally pollute the environment.

About the Product

Inside, the Dražice heater tank is made of special steel sheet, protected from corrosion by ENAMEL fired at 850 °C. By applying new technical knowledge and the most modern technologies, a high technical level of heaters has been achieved. Since the technical solutions are well thought out and high-quality materials are used, the heaters rarely break down and last a long time. The heaters are equipped with regulation and protection elements, which significantly improve operational safety and economy. A magnesium anode – additional protection against corrosion – also extends the tank's service life. The electric heating element (electric heating rod) is not immersed in water but is dry-fitted into a steel container welded to a steel junction cover. Since the heater tank and junction cover are made of the same material (steel), no galvanic pairs or electrochemical erosion occur. This is the biggest advantage compared to heaters with immersed heating elements, which are usually made of different metals (copper, stainless steel), leading to electrochemical corrosion. This ceramic element system is also suitable for hard and contaminated water and significantly extends the tank's service life. Sediments and limescale can be cleaned through access openings. Thermal insulation with a thickness of 42–60 mm (freon-free) guarantees low heat loss. Vertically mounted water heaters can be installed directly above the bathtub. The water temperature is set by a thermostat located on the exterior of the heater, further improving the product's features. A magnesium anode – additional protection against corrosion – also extends the tank's service life.

Purpose

The heaters are primarily designed for use in households, public social buildings, offices, pensions, shops, and other places where domestic hot water needs to be prepared with minimal costs. 20-liter water heaters heat water very quickly, making them especially convenient for installation in places where cold water is needed frequently and in short intervals, such as summer houses, small homes, kitchens, etc. In combined and indirect heating heaters, the entire tank volume can be heated by heating water from another heat source (e.g., a central heating boiler) via heat exchangers, saving electricity. Indirect heating heaters are most often used in conjunction with another water heating source (gas boiler, solar system, heat pump). Due to their high power, they guarantee sufficient hot water for large consumers, such as shopping centers, restaurants, and similar establishments. For high domestic hot water demand, they often operate similarly to a flow-through heater.
