When the cold comes, we all want to feel comfortable and warm at home. This is possible thanks to an apartment heating system.
Despite the fact that most apartments are smaller than houses, heating them in cold weather is not always easy and often not budget-friendly. Choosing the best heating system can certainly be a difficult process. Therefore, we will help you understand the best heating systems for apartment buildings so that you can choose the most efficient system for your home.
Central heating is a system whose heat source is a boiler house or CHP plant. As a rule, they are located outside heated buildings.
In most cases, heating in an apartment is carried out using a central system. Unfortunately, it is not efficient enough. We attribute this to several reasons:
the heating system is switched on and off according to the schedule of the state. Most often, the consumer has to freeze in the off-season due to the late switching on and early switching off of the central heating;
large heat losses during transportation of the heat carrier from the heat source to an apartment, as the heat carrier travels a long distance. Thus, during the passage of the heat carrier through pipelines, it loses a significant part of its temperature;
it is practically impossible to adjust the heating temperature in an apartment, since the control is carried out by the boiler room. Based on this, there may not be enough heat in an apartment, or vice versa, the room will overheat. All these points affect the human condition, since insufficient heating or overheating of an apartment will create discomfort for residents and may negatively affect their well-being.
We can conclude that apartment owners become "hostages" of utility service providers, since an apartment owner cannot influence the heating system on his own. That is why autonomous heating in an apartment is a more profitable option for the consumer in all aspects.
Gas heating is a system where a gas boiler of any type is used as a heat source. In turn, a gas boiler is a device that performs the function of heating and is able to provide residents with hot water, thanks to the combustion of gaseous fuels.
An atmospheric boiler is a unit that has an open combustion chamber so the boiler must be installed in a boiler room. The boiler has a significant drawback, due to which it is not popular among consumers – it is impossible to control the temperature. Thus, when the boiler is turned on, it can only work at full capacity.
A turbocharged boiler is a device with a closed type combustion chamber. The principle of operation of the device is that air is supplied to the combustion chamber by means of a fan through a coaxial flue or through a room. In turn, the coaxial flue is a "pipe in pipe" device. This means that 2 processes can be carried out at the same time: drawing in outside combustion air and throwing the exhaust gas out. This boiler is not in high demand among buyers, because it has a low efficiency. Since, during the process of gas combustion and energy transfer to the heat carrier, part of the heat is lost.
The most efficient device is a condensing type boiler. The principle of operation of the boiler is based on the condensation process:
Condensation occurs when warm and cold air streams come into contact. Accordingly, hot air is carbon dioxide, which comes up from the combustion chamber, and cold air enters from top to bottom into the heat exchanger through a coaxial flue. *The principle of operation is "pipe in pipe" - the inner pipe is hot, and the outer pipe is cold.
After that, heat is released in the form of hot water masses, which is fed into the heating circuit and used to heat the chilled water in the return pipeline. Thus, preheated water is supplied to the burner, which in turn reduces energy costs.
The system also uses the residual heat from the flue gases. Thus, through the air supply pipe, which is located in the flue, the incoming air is heated due to the heat of the exhaust gases. Accordingly, already warm air enters the burner, thereby providing additional energy savings. Therefore, because additional energy is used in the system, the efficiency of the boiler can exceed 100%. Another advantage of the boiler is the presence of weather compensation control. With the help of a sensor located on the street, the temperature of the heat carrier is adjusted to maintain comfort in the house.
Based on this, a condensing boiler is most suitable as a heat source for an apartment. It should be noted that for the efficient operation of the heating system, it is necessary to fulfill the requirement regarding the temperature of the heat carrier, as well as the area of underfloor heating should cover maximum of the floor surface. For a condensing boiler, it is necessary to provide a heating carrier supply temperature of +50°C, respectively, a return heat carrier temperature of +35°C. Thus, the lower the water supply temperature, the more efficient the operation of the gas boiler.
The disadvantage of the condensing boiler is the uncontrolled gas pricing policy in Ukraine, due to the war in Ukraine.
Heating in an apartment based on a heat pump is a profitable solution, since the heat source is able to provide residents with 3 functions:
hot water supply (DHW).
There are three types of heating systems in an apartment:
An air-to-air heat pump — the appearance of the unit resembles a classic air conditioner, but it can operate at low temperatures. These heat pumps are not common in Ukraine, as they have significant disadvantages:
if an outside temperature is -20℃, the heat pump will not be able to effectively heat an apartment;
if the system is turned off, the room cools down quickly;
the location of the indoor unit of the heat pump at the top of the room is not a very effective solution. Since warm air always rises, the supply of heated air from the top of the room will lead to the accumulation of warm air under the ceiling. In addition, there will be cool air at the bottom of the room, which will cause discomfort to residents.
If you have a heat meter installed in your apartment, then the residents of the house can switch to individual heating in an apartment - to an electric boiler, an air-to-water heat pump or a gas boiler.
Alter Air invites you to a consultation in our showroom, which is located in Kyiv. Our experts will select suitable heating for your apartment, as well as taking into account the wishes and budget of the customer.

Individual heating in an apartment based on an air-to-water heat pump is the most cost-effective solution. You can find out more about this heat source in the "Heat pump heating" section.
In case when residents have apartment heating of an individual type, it is not necessary to turn off the heating. Since an apartment has a heat meter. Thus, the heat meter does not spin - the client does not pay for the service.
However, if there is no heat meter in an apartment, unfortunately, you can’t turn off the central heating in any way and you will have to pay depending on the area of your apartment.
The cost of implementing heating in an apartment depends on the specifics of the object itself, the selected equipment, the piping of the boiler room, the complexity of installation and other factors.
