sähkökattiloiden

Sähkökattilat, known in English as electric boilers, are heating devices that utilize electrical energy to heat water, which is then circulated through a heating system. They are commonly used for space heating in residential and commercial buildings, as well as for providing hot water.

The fundamental principle of an electric boiler is the conversion of electrical energy into heat. This is typically achieved through heating elements, similar to those found in electric kettles or toasters, which are immersed in water. When electricity flows through these elements, their resistance causes them to heat up, transferring thermal energy to the surrounding water. This heated water can then be pumped to radiators, underfloor heating systems, or directly to hot water taps.

Electric boilers offer several advantages, including simplicity of installation and operation, relatively low initial cost compared to other boiler types, and quiet operation. They also do not produce any local emissions, making them a cleaner option at the point of use. However, their primary disadvantage is the operating cost, as electricity can be more expensive than natural gas or other fuels, especially in regions where electricity is generated from fossil fuels. The efficiency of electric boilers is very high, typically close to 100%, meaning almost all the electrical energy consumed is converted into heat. Maintenance requirements are generally minimal. They are often chosen for properties not connected to a gas supply or as a backup heating solution.
