sädeputket

Sädeputket, a Finnish term translating to "ray tubes" or "radiator tubes," typically refers to a component used in certain types of heating systems. These are often found in older or specialized radiant heating installations. The primary function of sädeputket is to transfer heat from a circulating medium, such as hot water or steam, to the surrounding environment through radiation and convection.

These tubes are designed to maximize surface area exposed to the space being heated. They are usually made of metal, such as steel or copper, to facilitate efficient heat transfer. In some applications, the tubes might be finned to further increase their heat-dissipating capacity. The design can vary, but they are often arranged in a series or grid pattern to provide a broad area of warmth.

Sädeputket are a form of radiant heating, meaning they directly warm objects and surfaces in their line of sight, rather than primarily heating the air. This can lead to a more comfortable and even heat distribution. While less common in modern residential construction compared to central heating systems with radiators or forced air, they still exist in some industrial settings, older buildings, and specific niche applications where their particular heating characteristics are desired. Maintenance and efficiency considerations can be different from contemporary heating solutions.
