küttevee

Küttevee is a Finnish term that translates to "heating water" or "hot water for heating." It refers to the water that circulates through a building's heating system, carrying thermal energy from a heat source to radiators, underfloor heating, or other heat emitters. This water is heated, typically by a boiler or heat pump, and then pumped through the pipes to warm the interior spaces. As it transfers its heat, the water cools down and returns to the heat source to be reheated, creating a continuous loop.

The quality of küttevee is important for the efficient and long-term functioning of a heating system. Over time, impurities can enter the water, leading to scale buildup, corrosion, and reduced heat transfer efficiency. Therefore, regular maintenance, such as flushing the system and adding water treatment chemicals, is often recommended to keep the küttevee clean and prevent damage to the heating components. The temperature of the küttevee is controlled by a thermostat, ensuring a comfortable indoor environment while optimizing energy consumption. In some systems, the küttevee may also be used to supply domestic hot water, although this is often handled by a separate circuit or a dedicated hot water tank.
