Vedelkütt

Vedelkütt is a term of Estonian origin that generally refers to a liquid heating system or a system that uses a liquid as a medium for heating. In practical terms, it most commonly describes a central heating system where water or a water-based mixture is heated and then circulated through pipes to radiators or underfloor heating elements to warm a building.

The basic principle of a vedelkütt system involves a heat source, such as a boiler (powered by gas, oil, electricity, or biomass), which heats the circulating fluid. This heated fluid is then pumped through a network of pipes to various parts of the building. As the liquid flows through radiators, heat is transferred to the surrounding air, warming the space. The cooled liquid then returns to the heat source to be reheated, completing the cycle.

Modern vedelkütt systems often incorporate advanced controls, such as thermostats and programmable timers, to regulate temperature and optimize energy efficiency. These systems can be designed for both residential and commercial applications. The circulating liquid itself is typically water, often mixed with antifreeze agents (like glycol) to prevent freezing in colder climates, especially in outdoor pipes or unheated areas. The efficiency and effectiveness of a vedelkütt system depend on factors such as the insulation of the building, the design of the heating elements, and the proper maintenance of the system.
