An air-to-water heat pump is a modern, environmentally friendly solution for heating homes and producing domestic hot water , which prioritizes energy efficiency and sustainability. This system utilizes the thermal energy in the outdoor air, which is extracted using a refrigerant , and then transfers the heat to water through a heat exchanger .
How does an air-to-water heat pump work?
Extraction of heat energy from the air: The system extracts heat from the air using a heat exchanger located in the outdoor unit, even at low ambient temperatures.
Refrigerant flow: The refrigerant absorbs heat from the air, which is compressed by the compressor , increasing its temperature.
Heat transfer to water: Heat is transferred to water through the heat exchanger, which is used in heating systems (e.g. underfloor heating, radiators) or for the production of domestic hot water.
Energy-efficient cycle: The process is continuously repeated, so the system can produce heat with minimal electrical energy consumption.
Advantages of an air-to-water heat pump
Energy efficiency: An air-to-water heat pump can produce up to 4-5 times more heat energy than it uses in electrical energy, thanks to its high COP (coefficient of performance) value.
Environmentally friendly operation: The system significantly reduces carbon dioxide emissions because it utilizes renewable environmental energy.
Cost savings: The costs for heating and domestic hot water production can be significantly reduced compared to traditional systems.
Easy installation and flexible use: It can be easily integrated into existing heating systems and can be used with underfloor heating, radiators or combined systems.
Winter and summer application: Suitable not only for heating, but also for cooling in summer, if the system is optimized for this.
Summary
Air-to-water heat pumps are a modern and sustainable solution for heating, cooling and hot water supply in homes and small commercial facilities. Due to their energy efficiency, environmental friendliness and long-term cost savings, they are an increasingly popular choice among those looking to reduce their energy consumption and carbon footprint.
