lisälämmönlähteet

Lisälämmönlähteet refers to supplementary heating sources used to augment a building's primary heating system or to provide heat in specific areas or situations. These can include various technologies designed to increase comfort, compensate for heat loss, or ensure a minimum temperature.

Common lisälämmönlähteet include electric heaters such as fan heaters, radiant heaters, and oil-filled radiators, which are often portable and used for temporary or localized heating needs. Wood-burning stoves and fireplaces are another category, providing both heat and a visual ambiance, though they require fuel and maintenance. Pellet stoves offer a more automated wood-based heating solution.

In some contexts, heat pumps, especially air-to-air heat pumps, can function as a lisälämmönlähde, supplementing a central heating system or providing efficient zone heating. Solar thermal systems, while primarily for hot water, can also contribute to space heating, especially in conjunction with other systems. Infrared heaters, which directly warm objects and people rather than the air, are also considered supplemental heating.

The choice of lisälämmönlähde depends on factors such as installation cost, running cost, heating efficiency, environmental impact, and the specific heating requirements of the space. They are often employed in older buildings with poor insulation, during extreme cold spells, or in rooms that are difficult to heat adequately with the main system.
