Kiertovesilämmitys

Kiertovesilämmitys, also known as hydronic heating, is a central heating system that uses a boiler to heat water, which is then circulated through pipes to radiators or other heat emitters in a building. The heated water flows from the boiler to the radiators, where it transfers its heat to the surrounding air, warming the room. As the water cools, it returns to the boiler to be reheated, creating a continuous loop.

The core components of a kiertovesilämmitys system include a boiler, which can be fueled by various sources such as natural gas, oil, electricity, or biomass. The boiler heats the water to a desired temperature. A pump is essential for circulating the heated water throughout the system. Pipes, typically made of copper or PEX, carry the water from the boiler to the heat emitters and back. Radiators are common heat emitters, but underfloor heating systems and fan coil units are also used. Control systems, including thermostats, regulate the water temperature and flow to maintain a comfortable indoor environment and optimize energy efficiency.

Kiertovesilämmitys systems are known for their even heat distribution and quiet operation. They offer flexibility in fuel sources and can be integrated with renewable energy technologies like solar thermal collectors. Maintenance typically involves checking water pressure, bleeding radiators to remove air, and ensuring the boiler is functioning correctly. While initial installation costs can be higher than some other heating methods, the long-term efficiency and durability of kiertovesilämmitys often make it a cost-effective choice.
