How to choose air conditioning for heating?
The most important factor to consider when choosing an air conditioner is the power of the device adapted to the area or volume of the room to be serviced. The degree of insulation of the building is also important.
It is usually assumed that:
● a room with an area of up to 25 m2 requires an air conditioner with a capacity of 2.5 kW
● a room with an area of 25 to 40 m2 should be served by a 3.5 kW unit
● a room larger than 40 m2 should be served by a device with a capacity of 5,0 kW or more.
Air conditioner for heating or supplementary heating?
The basic issue that you need to consider when choosing an air conditioner with a heating function is the climate zone in which you live. This is particularly important in a situation where the air-to-air heat pump will act as the primary source of heating. In the case where the air conditioning will be a supplement to the existing heating system or you will use it only to heat the air in transitional periods (spring and autumn), the temperature range in which the air conditioner provides heating is no longer so important.
Currently, most air conditioners on the market are equipped with both a cooling and heating function. Standard models of most brands provide efficient operation at temperatures reaching -10 degrees Celsius. Such devices will work well in heating rooms in the colder seasons and as an additional source of heat.
Air Conditioner for Heating - What Temperature Range?
If you decide to heat your home with an air-to-air heat pump — traditional air conditioning — you need to choose a unit that is designed to work in extreme temperature conditions. There are air conditioners on the market that operate in a very wide temperature range — even from -30°C to +48°C.
Air conditioners dedicated to heating in the basic range are equipped with similar systems as most air conditioners. They have an inverter compressor, which smoothly adjusts the unit's operation to maintain the set temperature in the room. At the same time, to obtain the expected efficiency, they have additional equipment elements that guarantee high efficiency, higher energy efficiency and reliability of operation even at extremely low temperatures.

Key factors you need to consider
High energy efficiency
So what is the best air conditioning for home with heating? Air conditioners designed for colder climates are optimized for energy efficiency in heating. These units have significantly higher heating capacity at lower temperatures than standard units. Therefore, when choosing an air conditioner for heating, it is worth verifying its SCOP coefficient, or seasonal energy efficiency coefficient. The higher this coefficient, the better the performance and energy efficiency characteristics of the unit.
What does the SCOP coefficient mean? It is the average ratio of heat energy produced by the air conditioner to the electrical energy consumed by the unit. Let's check with an example. If the SCOP coefficient is 5,0, it means that on average from 1 kW of electrical energy consumed, the air conditioner can produce 5,0 kW of heat energy.
An example of such solutions are air conditioners designed for heating by Daikin. Standard units, which are not dedicated to winter heating, have a much lower heating capacity at temperatures below 0°C. For example, the Perfera in the standard version at an outside temperature of -15°C has a heating capacity of 2.02 kW, and the Perfera Nepura (a line of devices designed for heating) provides a heating capacity of 4.52 kW. This makes it 2 times more efficient in terms of heating than the standard model.
Various solutions for energy saving
Air conditioners designed for heating use several technological solutions, thanks to which they have higher energy efficiency and at the same time higher efficiency of operation. They are often equipped with an automatic defrosting function, which removes ice from the external unit. Usually, external units of air conditioning designed for heating have a compressor heater and a drip tray heater, which prevent the unit from freezing. These solutions promote higher efficiency of operation in winter.
More advanced units have a built-in fireplace effect function, which ensures that air conditioning works in conjunction with fireplace heating. How does it work? If the temperature reading in the air conditioner indicates that the room has the set thermal conditions due to the fireplace, the device will turn off the heating and switch to ventilation mode, which will help evenly distribute the temperature in the room. As a result, you can find air conditioners with a heating function with the highest energy class A+++.
Additional air conditioning features that are useful in use
Choose the control that suits your preferences
Without a doubt, comfort of use is an important role when choosing air conditioning, including air conditioners designed for heating. Controlling the units plays a special role here, which is possible in several different ways. As a standard, manufacturers usually provide a remote control that allows you to use all the air conditioning functions. Often, the units have built-in Wi-Fi modules as part of the basic equipment, thanks to which you can control the air conditioning from anywhere on earth and at any time. In such a case, all you need to do is have an application installed on any mobile device. Air conditioners, including those designed for heating, often have other methods of controlling the system as an option. An example are wall controllers, which can be local or central.
Air purification
For many users, an important task of air conditioning is air purification. The devices use many different filters and technologies that help to purify the air in the room from dust, allergens, viruses, bacteria and fungal spores. More advanced filters also eliminate unpleasant odors and PM 10 and PM 2.5 smog particles. If you care about really clean, fresh and healthy air in your home, choose premium models equipped with air ionization systems that purify the air in rooms even more effectively.
Fast heating
When choosing air conditioning for heating, it is worth choosing devices that offer additional operating modes that affect the rapid achievement of a specific temperature. Consider whether you will need a quick heating function, or maybe you prefer the underfloor heating mode offered by floor air conditioners, so-called consoles.
Air distribution in the room
For the comfort of users, it is important to evenly distribute the temperature in the room. The key here will be the method and power of the airflow, as well as the temperature readings in different parts of the room. In technologically advanced air conditioners, both the 3D airflow mode and the Coanda effect or matrix temperature measurement or presence sensors are used. This eliminates the risk of feeling "drafts" and at the same time ensures even distribution of temperature throughout the room.
Protection against cold
Heating air conditioners are ideal for maintaining room temperature. In situations where minimal heating is required to eliminate the risk of water and sewage freezing, heating air conditioners will be effective in maintaining a temperature of 8 degrees Celsius regardless of the outside conditions.
Among air conditioners intended for heating, the most popular are devices from the Daikin, Mitsubishi and LG brands.

Is heating with an air conditioner profitable?
Heating with an air conditioner is not only convenient, but can also be economical. If we compare heating with air conditioning to traditional heating systems, such as electric heaters or gas furnaces, it turns out that a wall air conditioner with a heating function uses less energy. At the same time, an additional advantage of air conditioning is the fact that it heats the room faster.
It is worth emphasizing that modern air conditioning systems require 3 to 5 times less energy for heating than classic electric heaters. It is worth adding that air conditioners provide not only heating, but above all, additional heating of rooms, which is a convenient solution in transitional periods. Air conditioning can also be cheaper than heating with gas and electric convection heaters.
It is worth adding that air conditioning heating can be even more economical when it uses electricity generated from renewable energy sources. Air conditioning, like other heat pumps, commonly occurs in tandem with photovoltaics. As a result, achieving a comfortable temperature in rooms is even cheaper.
So how much electricity does air conditioning use in heating mode? The actual electricity consumption depends on the power of the device, the outside temperature and the user's settings. Let's use examples.
| Air conditioner | Energy consumption per 1 hour | Average price per 1kWh | Monthly cost for 6 hours of heating per day |
| air conditioner with a power of 2,5 kW | 0,6–0,8 kWh/h | 0,80 PLN | 86 - 115 PLN |
| air conditioner with a power of 3,5 kW | 0,8–1,2 kWh/h | 0,80 PLN | 115 - 170 PLN |
| air conditioner with a power of 5,0 kW | 1,3–1,8 kWh/h | 0,80 PLN | 187 - 259 PLN |
Where will air conditioning heating work best?
Air conditioners can be successfully used for heating in any room. This type of heating will be particularly effective in buildings that are characterized by an appropriate degree of insulation.
Air conditioning for heating can be used in:
● apartments
● single-family homes
● offices
● service premises
● holiday homes
● workshops
● garages
Portable air conditioner with heating function
You can use not only split or multisplit air conditioning to heat a room. Of course, these solutions are the most effective when it comes to air-to-air heat pumps. However, there are situations when there are no technical or legal possibilities to install stationary air conditioning. Then it is worth choosing a portable air conditioner with a heating function.
Portable air conditioners with a heating function are designed to serve rooms during both hot and colder periods of the year. You can successfully use them to heat rooms, but you must be aware that such devices have too little power to handle heating rooms in low, winter temperatures.
