<\/figure>\n\n\n\nHow does an air-to-water heat pump work?<\/h2>\n\n\n\n
Extracting heat from the air<\/h3>\n\n\n\n
The outdoor unit of the system extracts heat from the ambient air. This heat:<\/p>\n\n\n\n
- \n
- is present even at low external temperatures,<\/li>\n\n\n\n
- and can be utilized with the help of a closed refrigerant circuit.<\/li>\n<\/ul>\n\n\n\n
The refrigerant can evaporate even at low temperatures, allowing it to transfer heat energy absorbed from the air to the inside of the system.<\/p>\n\n\n\n
Heat transfer to the heating system<\/h3>\n\n\n\n
The absorbed heat is transferred to the water in the heating system via a heat exchanger.<\/p>\n\n\n\n
This heated water circulates:<\/p>\n\n\n\n
- \n
- in underfloor heating,<\/li>\n\n\n\n
- in radiators,<\/li>\n\n\n\n
- in fan coil units,<\/li>\n\n\n\n
- and in the domestic hot water tank.<\/li>\n<\/ul>\n\n\n\n
The use of water as a medium makes the air-water heat pump central heating system<\/strong>, as opposed to air-to-air solutions.<\/p>\n\n\n\n
What can an air-to-water heat pump be used for?<\/h2>\n\n\n\n
Heating<\/h3>\n\n\n\n
The primary function of an air-water heat pump is heating. The system:<\/p>\n\n\n\n
- \n
- works most efficiently with low-temperature heating systems,<\/li>\n\n\n\n
- Particularly well suited for underfloor heating and wall heating.<\/li>\n<\/ul>\n\n\n\n
However, with proper planning:<\/p>\n\n\n\n
- \n
- can also be used with modern radiators,<\/li>\n\n\n\n
- Can also be installed during renovations.<\/li>\n<\/ul>\n\n\n\n
Cooling<\/h3>\n\n\n\n
Many people are unaware that air-to-water heat pumps also suitable for cooling<\/strong>. In this mode, the system draws heat from the interior and releases it into the outside air.<\/p>\n\n\n\n
Cooling can be achieved by:<\/p>\n\n\n\n
- \n
- fan coil units,<\/li>\n\n\n\n
- through floor or wall surfaces (surface cooling).<\/li>\n<\/ul>\n\n\n\n
However, proper regulation and humidity control are important to prevent condensation.<\/p>\n\n\n\n
Domestic hot water (DHW)<\/h3>\n\n\n\n
The air-water heat pump can also meet daily hot water demand with the help of a separate DHW tank.<\/p>\n\n\n\n
This means that a single system can replace:<\/p>\n\n\n\n
- \n
- the boiler,<\/li>\n\n\n\n
- the boiler,<\/li>\n\n\n\n
- and partly the climate as well.<\/li>\n<\/ul>\n\n\n\n
Why is this type of heat pump so popular?<\/h2>\n\n\n\n
The popularity of air-to-water heat pumps stems from several factors:<\/p>\n\n\n\n
- \n
- no drilling or major earthworks required,<\/li>\n\n\n\n
- can be installed more quickly than ground source heat pumps,<\/li>\n\n\n\n
- can be easily combined with existing heating systems,<\/li>\n\n\n\n
- Particularly effective solution in combination with solar panels.<\/li>\n<\/ul>\n\n\n\n
For these reasons, it is often the first choice for those who:<\/p>\n\n\n\n
- \n
- are looking for a modern, electric-based heating system,<\/li>\n\n\n\n
- I would like to reduce fossil fuel consumption,<\/li>\n\n\n\n
- think long-term about the energy supply for their property.<\/li>\n<\/ul>\n\n\n\n
Advantages and disadvantages of air-water heat pumps<\/h2>\n\n\n\n
Advantages \u2013 why do so many people choose it?<\/h3>\n\n\n\n
One of the biggest advantages of air-to-water heat pumps is that complex system serving the entire house<\/strong> It works. A single device can replace a traditional boiler and, with the right design, can also cover some of the cooling needs.<\/p>\n\n\n\n
The advantages include:<\/p>\n\n\n\n
- \n
- Uses renewable energy sources<\/strong>
The system utilizes the heat content of the ambient air, thereby significantly reducing fossil fuel consumption.<\/li>\n\n\n\n- Can ensure lower operating costs<\/strong>

Although it may pay off in the long run, the initial investment is significant.<\/li>\n<\/ul>\n\n\n\nEfficiency and performance \u2013 what do the numbers mean?<\/h2>\n\n\n\n
Interpretation of COP and SCOP values<\/h3>\n\n\n\n
The efficiency of air-to-water heat pumps is generally characterized by COP (Coefficient of Performance) and SCOP (Seasonal COP) values.<\/p>\n\n\n\n
- \n
- COP<\/strong>: efficiency measured in a given operating condition<\/li>\n\n\n\n
- SCOP<\/strong>: average efficiency over an entire heating season<\/li>\n<\/ul>\n\n\n\n
The higher these values are, the more efficiently the system operates.<\/p>\n\n\n\n
However, it is important to note that manufacturer data is based on ideal conditions, and actual efficiency depends on the design of the building and the system.<\/p>\n\n\n\n
What affects efficiency?<\/h3>\n\n\n\n
The efficiency of an air-to-water heat pump is influenced by several factors:<\/p>\n\n\n\n
- \n
- outside temperature,<\/li>\n\n\n\n
- flowing water temperature,<\/li>\n\n\n\n
- type of heat sinks,<\/li>\n\n\n\n
- building insulation,<\/li>\n\n\n\n
- quality of regulation.<\/li>\n<\/ul>\n\n\n\n

- available electrical capacity.<\/li>\n<\/ul>\n\n\n\n
These factors determine whether the system will actually be a good choice for the property in question.<\/p>\n\n\n\n
Installation of air-water heat pump<\/h2>\n\n\n\n
Main steps of installation<\/h3>\n\n\n\n
Installing an air-to-water heat pump is a more complex process than installing a conventional boiler, but it does not require the same amount of groundwork or permits as ground-source or water-source systems.<\/p>\n\n\n\n
Typical installation steps:<\/p>\n\n\n\n
- \n
- Heat demand calculation and system design<\/strong>
This determines the required performance and suitability of the heat sinks.<\/li>\n\n\n\n- Outdoor unit placement<\/strong>
Proper ventilation, noise protection, and frost protection are important.<\/li>\n\n\n\n- Installation of indoor unit and hydraulic components<\/strong>
This includes the buffer tank, DHW storage tank, and control system.<\/li>\n\n\n\n- Electrical connection and control settings<\/strong><\/li>\n\n\n\n
- Trial operation and fine-tuning<\/strong><\/li>\n<\/ol>\n\n\n\n
Accurate installation has a fundamental impact on the subsequent efficiency and service life of the system.<\/p>\n\n\n\n
Placement considerations and noise level<\/h3>\n\n\n\n
The placement of the outdoor unit is a critical issue. The following must be taken into account:<\/p>\n\n\n\n
