- 🏠 Ventilation in the house made of aerated concrete
The construction of a house begins with the choice of building material. Most often, the choice falls on the fast and cost-effective option, such as a house built of aerated concrete.
Let us first understand what aerated concrete is. This is a lightweight building material that has high thermal insulation properties. Therefore, the house built of aerated concrete will become warm and reliable. To organize comfortable living conditions in such a house, it is necessary to ensure proper air exchange.
We also should take into account high moisture-absorbing properties of aerated concrete. Therefore, it is ventilation in an aerated concrete house that will help minimize the consequences of such characteristics of this building material.
We suggest that you familiarize yourself with the principles of implementation and equipment that can be used in the organization of ventilation. The ventilation system in a house made of aerated concrete can be arranged in several ways:
Doesn’t imply a presence of professional air extraction equipment, because its principle is based on the usual ventilation of the dwelling.
For the implementation of natural air exchange, it is not common to use any mechanical systems. This method implies that the movement of air occurs due to pressure differences.
Therefore, thanks to open window and exhaust ducts, the supply air enters the house, and is removed using centrifugal or axial fans in the toilets or in the bathroom.
A significant disadvantage of this method of ventilation in the house is the removal of heat and the poor quality of the supply air from the street. Natural-type ventilation in an aerated concrete house cannot fully “serve” it.
ImportantInstalling exhauts fans does not improve the supply of air into the home. Therefore, do not forget about the mandatory supply of fresh air indoors.
It is carried out with compact ventilation units Meltem, Zehnder, Maico PushPull and exhaust fans etc.
Such air exchange is implemented when natural ventilation in aerated concrete house is of poor quality. This can happen for various reasons, for example, when the air temperature is low outside, and you would rather not open the windows at all. Then, to improve the microclimate in the house, various mechanical ventilation devices are used that stimulate air circulation.
The ventilation system in an aerated concrete house can be organized using compact ventilation devices. The installation of ventilation devices is simple, they do not require laying air ducts or ventilation pipes. Such a system is decentralized, with the correct placement of equipment, it will provide the necessary air exchange throughout the building. Decentralized ventilation can be implemented using the following devices:
To organize the intake of exhaust air in all 3 options, it is necessary to install exhaust fans:
axial or centrifugal. They are installed in the so-called "dirty areas" - kitchen, bathroom, dressing room.
Thus, proper ventilation is ensured in the aerated concrete house: the supply of clean air with the help of supply devices and the intake of exhaust air with the help of exhaust fans.
Another option for organizing decentralized ventilation in the house is the use of compact ventilation units, such as Meltem or Zehnder. The Meltem air handling unit can be used for both decentralized and centralized ventilation in the house. Of course, more efficient air exchange will be carried out with the help of air ducts with centralized ventilation. However, if it is necessary to provide ventilation for a house with a finished renovation, the Meltem compact ventilation unit is an excellent option.
Another option of implementing ventilation in aerated concrete houses is using ventilation devices with heat recovery from the German manufacturer Maico. They are installed in a wall hole both in a building under construction and during repair work in a residential building and provide air supply in "clean" rooms. The absence of door thresholds promotes air flow through the rooms, and the air exhaust is carried out in “dirty” areas using Maico ER household exhaust fans.
We invite you to look at the layout of Maico PushPull ventilation equipment in one of our projects.
Benefits of Maico PushPull compact ventilation units:
Implemented with air-intake ventilation units such as: Jablotron Futura, Maico WS, Systemair SAVE VTC, etc.
A profitable investment in further comfortable living in the house will be the use of air-handling unit with heat recovery. Ventilation of an aerated concrete house thanks to such equipment is carried out throughout the house thanks to air ducts through which air moves. Therefore, such a system is called centralized. The air handling unit consists of one casing, which contains all the necessary components – fans, heat exchanger, heater, and filters for air purification. In this design, the equipment is easy to manage and there will be no difficulties in operation.
The heat recuperator in the unit unloads the heating system, taking heat from the exhaust air and transferring it to the supply air, thereby heating it. The availability of such an element in the air-handling unit allows you to save on energy resources during the cold period of time, especially taking into consideration ever-increasing tariffs.
To organize a centralized ventilation system, you can use air handling units of well-known brands:
Today, one of the most popular and requested models of centralized ventilation units is the Jablotron Futura L/M. It is perfect for supplying fresh air and extracting exhaust air in both houses and apartments. This unique equipment combines simplicity and sophistication in design, as well as high efficiency, energy efficiency, multi-level air purification and convenient remote control.
It is also important to note the availability of an enthalpy heat exchanger that reuses heat, as well as excess humidity in the premises, for its recycling.
Thanks to a system of VAV-клапанов the equipment can supply air separately to each room in case the level of carbon dioxide in a particular room has exceeded the norm. This function can not only provide more efficient air distribution, but also significantly save on resources. Accordingly, every resident will be able to feel comfortable, regardless of whether he is in the bedroom or living room.
Let's get acquainted with our project based on ventilation equipped with VAV-valves.
Moreover, when organizing ventilation in the kitchen, it is recommended to use a Faber kitchen hood together with a Jablotron ventilation unit equipped with VAV valves. In this case, when the kitchen hood in the kitchen is turned on, the ventilation system begins to intensively remove air in the cooking zone (the volume of intake air is preliminarily calculated by engineers and adjusted separately to the valve.) At the same time, in other “dirty areas” – a bathroom, a wardrobe, the VAV valves close automatically.
The main task and advantage of such a system is to ensure the balance of supply and exhaust air.
When the kitchen hood is activated in the kitchen, the volume of removed air may exceed the amount of supplied air. In this case, the ventilation unit increases its performance in order to compensate for the removed volume with supply air.
Another significant advantage of such a system is the preservation of the heat of the exhaust air. Because the Faber hood is connected to the general ventilation system, it does not just “throw out” the heat received from the frying surface along with the exhaust air, but, if necessary, reuse it thanks to the heat recovery.
It is important to note that Faber equipment has a filtration system that prevents grease and other contaminants from entering the heat exchanger.
Thus, effective ventilation in the house is ensured, the smells of cooking do not spread to other rooms, and the load on the heating system during the cold season is also reduced.
The units can be combined with smart home systems via ModBus, in this case you don’t even need to monitor the operation of the system because it will follow and adapt itself to the already programmed work scenarios.
Before proposing the concept of a ventilation system for the home, our specialists need to understand the wishes of the client, as well as get all the raw data on the facility. The meeting takes place either at the Alter Air showroom, where everyone can see, feel and manage different ventilation systems, or via video communication. After the meeting, the general decision is taken the concept of the ventilation project, according to which it will be implemented.
At this stage, the customer receives a package of documents on the ventilation system, namely: calculation of the air supply volume, as well as a final offer in 3 variants with different pricing solutions. The total cost of the ventilation system for the house, after drawing up an accurate design, can change up to 15% to a bigger or smaller side. At this stage, the client already clearly understands the future implementation of the system.
After the approval of the offer, we proceed to the design of the ventilation system. During the project preparation, our specialists contact not only the client, but also related specialists (designers, architects, foremen, etc.). After approval, the engineers issue a complete package of design documentation, according to which it is possible to implement the ventilation system even in another company.
We provide delivery and installation of ventilation systems. Installation of systems is carried out exclusively by our crews.

Often, the innovative ventilation equipment we work with often does not even require the presence of a specialist: analysis, setup and service can be carried out online. In case of faults – our service master will offer the best package of services and will come any day convenient for the client. Spare parts for repair or consumables (for example, replaceable ventilation filters) – can also be ordered from us.
Let us consider the most popular brands for organizing ventilation in an aerated concrete house, namely the equipment for supply and exhaust ventilation, as well as manufacturers of fans for extracting exhaust air during natural ventilation.
We offer to consider the popular series of air-handling units with heat recovery from world manufacturers.
Centralized air-handling units from the Czech manufacturer Jablotron of the Futura L/M series. Highly efficient equipment for high-quality ventilation at home, they quickly remove polluted air, after which they saturate the room with pleasant, fresh and purified air. They carry out multi-level air purification using F7 filters, reuse the heat of the exhaust air for space heating, and can significantly reduce energy consumption. In addition, the installation is easy to manage using the mobile application from MyJablotron.
Ventilation supply and exhaust equipment from the Swedish manufacturer Systemair is an alternative option if you are looking for high-quality and reliable equipment. With built-in high-efficiency plate recuperators, these devices have efficiency of up to 90%. Therefore, you will need less additional heating of air during the cold season. Looking at the equipment by series, we note a wide range of SAVE VTC (designation for air handling units with a high-performance counterflow heat exchanger). Fresh air enters the house at an already comfortable temperature, while reducing overall energy consumption for heating.
Air handling units from the German manufacturer Zehnder are perfect for ventilation of a small house made of aerated concrete. Zehnder has over 120 years of history in the HVAC market and is one of the leaders in innovations in climate control equipment. A series of COMFOAIR supply and exhaust ventilation units with efficient heat recovery (up to 90%) provides high-quality air in the house, keeping heat and moisture inside it. Zehnder equipment is characterized by low noise level, so the operation of the ventilation unit will not cause discomfort.
Another option for implementing ventilation in an aerated concrete house is the Meltem compact ventilation unit. This is a great option for rooms with a small area. The maximum productivity of the unit reaches 100 m3/h and has 5 operating modes. The enthalpy heat exchanger allows you to save heat and moisture of the air, reducing the load on the heating system. In addition to efficient ventilation, the air handling unit provides high-quality air purification using an F7 class filtration system. The M-WRG-II series is equipped with internal humidity and CO2 level sensors.
Fans are installed in those places where moisture accumulates most quickly, unpleasant odors. Consider the most popular brands.
Exhaust devices are installed in those places where moisture and unpleasant odors accumulate most quickly – kitchen, bathroom and toilets, pantry or dressing room. They locally neutralize contaminants and prevent them from spreading to clean areas. Two key characteristics that you should definitely pay attention to are the power of the fan and its noise characteristics. When choosing an exhaust device in the house, be guided by:
The ventilation equipment market offers a large selection of a wide variety of models of household fans, both in terms of functionality and design. Let's focus on three manufacturers that are worth paying attention to:
When building a private house, from the very beginning it is important to understand how the ventilation system will be organized: it will be natural, forced, or mixed, what equipment will be used. Once you have decided on the type of ventilation, you can begin to design it.
Ventilation in a house made of aerated concrete is designed according to the same principle as in houses made of other building materials. The main thing is that the project is developed by a competent specialist. Since without a quality project, the ventilation system in a aerated concrete house will work inefficiently and may be uncomfortable for living.
Ventilation ducts in an aerated concrete house are necessary for air intake from “dirty areas” – kitchens, bathrooms. They can be of the following types:
brick ventilation blocks
sleeving with plastic pipes
The second option is considered more efficient and moisture resistant, since condensation does not form on the plastic.
When using air handling units, there is no need to equip ventilation ducts. Air circulates through air ducts, which are located in the ceiling space. A high-quality exhaust system in a private house is the key to energy efficiency.
Ventilation in the house may work not properly and cause discomfort for residents. Violation of the ventilation system may occur due to improper design and installation. Consider common mistakes in the implementation of ventilation:
Nothing says better about our professionalism than our implemented projects.
The Jablotron Futura L ventilation unit with heat and moisture recovery ensures high-quality air exchange at the apartment, and also reduces the load on the heating system in the cold season. Thanks to the Alfa wall controller and the MyJablotron mobile app it is easy to operate the unit.
Flexible air ducts Airflex have a high degree of plasticity, which allows air to be supplied even to hard-to-reach areas. Moreover, they are covered with a layer of thermal insulation, which prevents heat loss and absorbs noise characteristics during the operation of the ventilation unit.
Thanks to galvanized steel, the duct does not suffer corrosion and other damaging influences. Thus, the long-term operation of the climate systems is ensured.
The Daikin duct air conditioner provides efficient room cooling. The FBA series has a rather thin body, which makes it easy to place in a ceiling space. The self-diagnosis function ensures a safe operation of the device and indicates problems if any occur.
Double-slot diffusers from the TROX brand are designed for high-quality air distribution throughout the room. They combine visual aesthetics and high technical potential. Air currents are given in different directions, evenly scattering and avoiding any drafts. Outwardly, only laconic lines on the ceiling remain visible.
A low-pressure internal duct unit Daikin FDXM 35F is installed in the ceiling space of the bathroom - it works to cool the bedroom. It is accessed through hatches. The capacity of the air conditioner is enough to service rooms up to 35 m2, which is optimal for a given room. The lowering of the ceiling in a technical room was 300 mm.
Vertical indirect heating boiler Drazice OKSE 200 l is designed to provide apartment residents with hot water. The inner surface of the tank is covered with high-quality enamel without nickel, which ensures a long operation of the water heater, and there is also an anti-corrosion coating. The temperature inside can be kept between 7 and 77 ℃. The water heating indicator always shows the current temperature on the front of the tank. There is a fast heating function. This is an excellent solution for an apartment, allowing you not to depend on seasonal blackouts and other inconveniences.

We chose Alter Air to bring our cool engineering project to build our own home. Now the following systems are installed in the house: heating with a heat pump, underfloor heating, supply and exhaust ventilation with heat recovery, which allows you to keep moisture and easily breathe fresh clean air. The house maintains an excellent temperature of + 22 ° C - no stuffiness and dust. Everything is magical!
I looked at several companies on the Internet and settled on the Alter Air company. After talking with their specialists, I realized that people are very well versed in their business. They sensibly explained how to implement home heating and ventilation correctly and with minimal cost. During my stay in a new house, I have already experienced the operation of these systems, and especially the ease of control. The temperature in the house is comfortable and kept at a given level. The ventilation works inaudibly, but noticeably - with the windows closed in the morning it breathes freely and easily, there is no dust. I am very pleased with the work of Alter Air and I will recommend you as a good performer who does quality work!
Definitely. Ventilation is necessary in a house made of any building material, especially of aerated concrete. Aerated concrete has a high moisture absorption, which can subsequently have a devastating effect on building materials. To take away excess moisture along with the exhaust air and saturate the room with oxygen, it is necessary to use a supply and exhaust ventilation system.
The price of a ventilation system in an aerated concrete house depends on the area of the house, the chosen system, the cost of equipment and other factors. You can get acquainted with the price list and buy ventilation units in Kyiv in the Alter Air online store.
For a house made of aerated concrete, Alter Air considers Jablotron supply and exhaust ventilation equipped with CO2 sensors and a VAV valve system for variable airflow to be the most profitable option. The system monitors the level of CO2 in each room, and directs its action exclusively to those areas where the air quality is below normal. Such a ventilation system provides effective and energy-efficient ventilation.
In a finished house made of aerated concrete, it is possible to make ventilation. To do this, it is necessary to take into account all the technical characteristics of the structure and interior, and choose the best option.
