värmeslinga

A värmeslinga, which translates to "heating coil" or "heating loop" in English, is a component used in various heating systems. Its primary function is to transfer heat from one medium to another. Typically, a värmeslinga is a tube or pipe bent into a spiral or serpentine shape. This design maximizes the surface area exposed to the fluid or gas it interacts with, thereby enhancing heat exchange efficiency.

Värmeslingor are commonly found in domestic hot water systems, where they are often submerged in a tank of water. A primary heating source, such as a boiler or solar collector, circulates a hot fluid (like water or a glycol mixture) through the värmeslinga. As the hot fluid passes through the coil, it transfers its thermal energy to the surrounding water in the tank, heating it up. This is a fundamental principle behind indirect water heaters.

Beyond hot water tanks, värmeslingor can also be integrated into central heating systems, radiators, and even some industrial processes requiring controlled heating. The materials used for värmeslingor vary depending on the application and the fluids involved, with common choices including copper, stainless steel, and various alloys to ensure durability and resistance to corrosion. The performance of a värmeslinga is influenced by factors such as its length, diameter, material, and the flow rate of the heating medium.
