Vesiilmalämpöpumppu

Vesiilmalämpöpumppu, which translates to "water-air heat pump" in English, is a type of heat pump system that utilizes ambient air as the heat source and water as the heat transfer medium for the heating system. Unlike air-to-air heat pumps that directly heat indoor air, vesiilmalämpöpumppu transfers heat from the outside air to water. This heated water is then circulated through radiators, underfloor heating systems, or other water-based heating distribution networks within a building. The system typically consists of an outdoor unit that extracts heat from the air, a refrigerant circuit, and an indoor unit that transfers this heat to the building's water system.

The primary advantage of a vesiilmalämpöpumppu is its ability to leverage existing water-based heating infrastructure, making it a suitable retrofit option for many homes. It can also provide hot water for domestic use. The efficiency of the heat pump is measured by its Coefficient of Performance (COP), which indicates how much heat energy is delivered for every unit of electrical energy consumed. The COP of a vesiilmalämpöpumppu varies with the outdoor air temperature, generally decreasing as the temperature drops. However, modern units are designed to operate effectively even in colder climates. Installation typically involves an outdoor unit and connections to the building's plumbing and electrical systems. Regular maintenance is recommended to ensure optimal performance and longevity.
