Hajdu STA 200 C

A large indirect heating storage boiler with a capacity of 200 liters from one of the well-known European manufacturers of household heating equipment, the Hungarian company Hajdu. Designed for vertical floor mounting. Designed to work with gas, liquid or solid fuel heating systems. It is also allowed to connect to solar collectors and other solar energy equipment. The surface area of the built-in tubular spiral heat exchanger, through which the hot coolant is passed, is 1.0 mm², and this is quite enough to transfer impressive heat output (up to 30 kW) and prompt water heating (up to 12.5 L / min, subject to heating at 45 °C).

The internal tank of the water heater Hajdu STA 200 C is made of high quality sheet steel and is designed for an operating pressure of up to 6 bar, the maximum design pressure in the heat exchanger is also 6 bar. The metal surface of the inner tank is insulated from hot water with glass-ceramic heat-resistant enamel. Additional protective protection of steel against corrosion is provided by a large magnesium anode. The water heater allows the installation of two electric heating elements (from 3 to 9 kW, purchased separately), turning it into a combined boiler. An important advantage of the device is reinforced polyurethane foam insulation, which significantly reduces losses.
