Keskuslämmitysvesi

Keskuslämmitysvesi refers to the water used in a central heating system. This water circulates through a boiler or other heat source, where it is heated, and then flows through a network of pipes to radiators or other heat emitters located in different parts of a building. After releasing its heat, the cooled water returns to the boiler to be reheated.

The quality of the keskuslämmitysvesi is crucial for the efficient and long-term operation of the heating system. Impurities in the water can lead to corrosion of pipes and components, scale buildup, and reduced heat transfer efficiency. Therefore, water treatment is often employed to maintain optimal water quality. This may include deaeration to remove dissolved gases like oxygen, which contribute to corrosion, and sometimes the addition of inhibitors to prevent chemical reactions within the system.

The water pressure within a central heating system is also an important factor. A properly pressurized system ensures that water can circulate effectively to all parts of the building and reach the desired temperature. Pressure is typically maintained by an expansion vessel or a pressure-reducing valve.

Keskuslämmitysvesi is a closed-loop system, meaning the water is recirculated. However, minor losses can occur over time, necessitating occasional replenishment. When adding new water, it is important to use demineralized or treated water to avoid introducing new impurities into the system. Regular monitoring of water quality and pressure is a standard maintenance practice for central heating systems to ensure reliable performance and prevent costly damage.
