lavtemperaturvarmeanlæg

Lavtemperaturvarmeanlæg, translated to low-temperature heating systems, are heating systems designed to operate with lower water temperatures compared to traditional heating systems. Typically, these systems distribute heat using water at temperatures between 30°C and 50°C, whereas conventional systems often operate at 70°C or higher. This lower operating temperature has several advantages, primarily related to energy efficiency and comfort.

One of the key benefits of low-temperature heating is its compatibility with renewable energy sources. Heat pumps, solar thermal systems, and condensing boilers are all highly efficient when paired with low-temperature distribution. Heat pumps, for instance, achieve a much higher coefficient of performance (COP) when the temperature difference between the heat source and the heating medium is smaller. Similarly, solar thermal systems can produce sufficient heat at lower temperatures, and condensing boilers extract more energy from combustion gases when the exhaust temperature is lower.

The most common form of heat emitters for low-temperature systems is underfloor heating. The large surface area of underfloor heating allows for effective heat distribution at lower temperatures, providing a comfortable and even warmth. Radiators designed for low-temperature operation are also available, often larger than conventional radiators to compensate for the reduced temperature difference.

The use of low-temperature heating systems can lead to significant energy savings and a reduction in carbon emissions. By operating at lower temperatures, less energy is lost through the heating system and distribution network. This not only lowers utility bills but also contributes to a more sustainable building. The gentler heat produced also often leads to a more pleasant indoor climate, reducing feelings of overheating and drafts.
