GULjärjestelmät

GULjärjestelmät, which translates to "GUL Systems" in English, is a term that typically refers to a specific type of heating and cooling system, often encountered in Nordic countries. These systems are characterized by their ability to provide both heating and cooling functions within a single installation. The core principle behind GULjärjestelmät involves circulating a fluid, usually water, through a network of pipes integrated into building structures.

In heating mode, the circulating fluid is heated, often by a central heat source such as a boiler or heat pump, and then flows through the pipes. This transfers heat to the surrounding building materials, which then radiate warmth into the living or working spaces. Conversely, in cooling mode, the fluid is chilled and circulated, absorbing heat from the environment and thus lowering the indoor temperature.

A key feature of GULjärjestelmät is the location of the pipes, which are commonly embedded within floors, hence the "GUL" (floor) designation. This floor-integrated approach allows for a more even and comfortable distribution of temperature throughout a room, minimizing drafts and temperature stratification. The systems are designed to be discreet, with no visible radiators or air vents, contributing to a cleaner aesthetic. Their implementation is often considered energy-efficient due to the large surface area for heat exchange.
