Kazánház

Kazánház, or boiler house, is a room or building that houses one or more boilers used to generate heat for space heating, domestic hot water, or process steam. In residential and commercial buildings, the kazánház is typically a basement or utility room; in district heating systems it forms part of a larger plant that heats multiple buildings.

The typical installation includes boilers, burners, fuel storage, feedwater systems, pumps and valves, heat exchangers, condensate return, expansion tanks, water treatment equipment, and a control panel. The exhaust gases are vented via a flue or chimney. Temperature and pressure controls ensure safe operation.

Boilers can be fire-tube or water-tube in design and may be fueled by natural gas, oil, biomass, or electricity. Modern systems emphasize efficiency, with condensing boilers reclaiming heat from flue gases. Some kazánházs also include cogeneration equipment (CHP) or feed into a district heating network.

Safety and regulation: Operation requires ventilation, gas detection, fire protection, regular inspection, and water treatment. Standards and codes vary by country and are enforced by building and energy authorities; common references include EN standards and ASME for pressure equipment.

In Hungary and Central Europe, the term kazánház denotes the room containing the heating plant; its scale ranges from small apartment-house installations to large municipal or industrial plants.
