matalalämpöjärjestelmän

Matalalämpöjärjestelmä refers to a low-temperature heating system in Finnish. These systems are designed to operate with significantly lower water temperatures than traditional high-temperature radiators. Typically, the supply water temperature in a matalalämpöjärjestelmä is between 30 and 55 degrees Celsius, whereas conventional systems might use temperatures above 70 degrees Celsius. This lower operating temperature has several key advantages, primarily related to energy efficiency and comfort.

One of the main benefits of matalalämpöjärjestelmät is their compatibility with renewable energy sources. They are particularly well-suited for use with heat pumps, solar thermal systems, and geothermal energy, which often produce heat at lower temperatures. By operating at lower temperatures, these systems can extract more heat from the environment or solar radiation, leading to reduced energy consumption and lower heating costs. Additionally, the efficiency of heat pumps increases as the temperature difference between the source and the delivery system decreases.

Comfort is another significant aspect. Low-temperature systems are often paired with large surface area emitters, such as underfloor heating or low-temperature wall radiators. These larger emitters distribute heat more evenly throughout a room, creating a more consistent and pleasant indoor climate with less stratification of air temperature. They also reduce the risk of overheating and can help to mitigate drafts often associated with high-temperature radiators. The slower response time of underfloor heating, for instance, means that once a desired temperature is reached, it is maintained more steadily.

The implementation of a matalalämpöjärjestelmä can involve various technologies, with underfloor heating being the most common. However, it can also include specially designed low-temperature radiators or fan coil units. When retrofitting existing buildings, careful consideration must be given to the existing heat distribution system and insulation levels to ensure optimal performance.
