lämpöpumpulämmitys

Lämpöpumppulämmitys, known in English as heat pump heating, is a system that transfers thermal energy from a source of heat to a heat sink using a mechanical compression and expansion cycle. This process is highly energy-efficient as it moves heat rather than generating it directly through combustion. Heat pumps can extract heat from various sources, including outdoor air, ground, or water, even when ambient temperatures are low.

The most common types of heat pumps used for heating are air-to-air, air-to-water, and ground-source (geothermal) heat pumps. Air-to-air systems transfer heat from the outside air to the indoor air, often used in conjunction with ventilation systems. Air-to-water systems extract heat from the outdoor air and use it to heat water for central heating systems, such as radiators or underfloor heating, and domestic hot water. Ground-source heat pumps utilize the stable temperature of the earth, typically accessed via buried pipes, to provide both heating and cooling.

The efficiency of a heat pump is measured by its Coefficient of Performance (COP), which is the ratio of the heat output to the electrical energy input. A higher COP indicates greater efficiency. While heat pumps consume electricity to operate the compressor and fan, their ability to move several units of heat for each unit of electricity consumed makes them a more energy-efficient and environmentally friendly alternative to traditional fossil fuel heating systems. This can lead to significant reductions in energy bills and greenhouse gas emissions.
