lämmityskierros

Lammityskierros, often translated as "heating circuit" or "heating loop" in English, refers to a closed system within a heating installation where a heat transfer fluid circulates. This fluid, typically water or a water-glycol mixture, carries thermal energy from a heat source, such as a boiler or heat pump, to various distribution points within a building. The lammityskierros is a fundamental component of hydronic heating systems.

The primary function of a lammityskierros is to efficiently transfer heat. The heat source raises the temperature of the fluid, which is then pumped through a network of pipes. This fluid travels to radiators, underfloor heating coils, or other heat emitters, where it releases its thermal energy into the surrounding space. After delivering its heat, the cooled fluid returns to the heat source to be reheated, completing the circuit.

Key components of a lammityskierros include the heat source, a circulation pump to move the fluid, piping to carry it, and heat emitters to distribute warmth. Expansion vessels are also crucial to accommodate volume changes in the fluid due to temperature fluctuations, preventing excessive pressure buildup. Control valves and thermostats regulate the flow of the heated fluid and the overall temperature within the building. The design and proper functioning of the lammityskierros are essential for an effective and energy-efficient heating system.
