It is not always easy to create the right conditions for an even and comfortable indoor climate. The challenge becomes even greater when the temperature differences vary between rooms and floors of the home.
One way to get around this problem is to install a heat exchanger. This will allow heat to be transferred more easily from warmer to cooler parts of the home. This will also even out temperature differences between different parts of the home.
In addition to greater comfort for all occupants, you will also save both energy and money. To broaden your understanding of the subject in question, in this guide we will explain how a heat exchanger works, why you should get one and how to optimize your home!
How does a heat exchanger work?
The main task of a heat exchanger is to transport the warm air from one room to other parts of the home. This in turn creates the conditions for a more even indoor climate. The following table gives an overview of how a heat exchanger works in practice:
|
Component/Function |
Description |
|
Air intake |
The heat exchanger sucks cold air from a room, usually without a heat source, into a room with a wood-burning stove or heat pump. |
|
Airflow |
The built-in fan produces a constant airflow that moves the cold air to other parts of the home. |
|
Temperature equalization |
A constant flow removes the need for thermostat control and thus evens out the temperature around the clock, all year round. |
|
Air emissions |
The cold air is released into the warm room, which contributes to circulation and will then even out the temperature. |
|
Energy-efficient operation |
The fan operates with an operating cost of 3W, which corresponds to an energy cost of approximately 26 kWh on an annual basis during constant operation. |
|
Reverse function in summer |
During the summer months, heat exchangers can be used instead to circulate cool air from cold floors to warmer areas. |
Heat exchangers that run constantly with low energy consumption are particularly effective. The power adapter for Airmove 2.0 & Airmove 1.1 has 3 positions for fixed adjustments to the flow, which in turn can change the temperature in the rooms.
The above means that the heat exchanger will help improve airflow. Likewise, it will also reduce energy consumption, which in turn results in lower operating costs.
How do you increase the heat of the incoming and outgoing air?
To effectively distribute heat between two different rooms, it is crucial to configure the fan speed level. This is primarily determined by how much heat you want to transfer to other parts of the home.
A constant flow heat exchanger will do this automatically. If you find that, for example, the living room is colder than other parts of the home, you can adjust the adapter to a different operating mode to increase or decrease the speed of the fan.
This will result in a higher proportion of cold air being transported to the warm space.
This way you will be able to maintain a constant temperature. If you have multiple rooms that you want to circulate air in for more even heat distribution, you may need to install more than one unit.
How do you move heat between different floors?
A common problem when it comes to multi-storey houses is that heat does not tend to rise upwards. A cold cap is usually located between the 4th and 6th step of the staircase to the upper floor. Cold, moist air is heavier than warm air and therefore this temperature cap is formed, which needs a pull from above and a pressure from below. This means that the upper floor is often colder than, for example, the lower parts of the house when the heat source is on the lower level of the house.
This can in turn result in unpleasant temperature differences between the floors of the house. To solve this problem, it is recommended to use a heat exchanger that has been developed with the capacity to transfer heat between the lower floor and the upper floor.
Products like Airmove 2.0 are specifically designed for this purpose. By placing heat movers between the floors of the house, you can effectively circulate the warm air up to the upper floors!
Save money with a heat exchanger
There is a lot of money to be saved by investing in a heat exchanger. In fact, your investment can be repaid within just a few months if you live in a house with high consumption according to this table:

The calculations are based on:
● Up to 20 - 30% energy savings according to The Swedish Board of Housing, Building and Planning .
● Energy prices of approximately SEK 1.50/kWh , including electricity and heating.
● Average consumption of homes according to Swedish Energy Agency .
Why Airmove 2.0 is the right choice
The Airmove 2.0 heat exchanger has been designed to efficiently move air around the spaces and floors of your home. This way, the temperature becomes significantly more even and comfortable - no matter which part of the home you are currently in.
Some of the advantages of Airmove 2.0 include the following points :
● High energy savings and cost-effective heat transfer.
● Perfectly suited for air heat pumps and wood-burning stoves.
● Warm throughout the house during cold winter months
● Cool throughout the house during hot summer months.
● Extremely quiet and efficient in operation.
● Smooth and easy installation on your own.
Note : For this product to work optimally, there must be no negative pressure in your home. Otherwise, you will need to supplement the installation with our fresh air valve Airmove 3.0, which is specially designed to equalize the pressure in the different spaces of the home.

Closing words
A heat exchanger is one of the best investments you can make to create a consistent indoor climate. At the same time, the unit will also save energy, which ultimately means lower operating costs.
We recommend you invest in one of our heat movers, such as Airmove 1.1 or Airmove 2.0 . The products have been designed with a focus on optimizing the airflow between different rooms, while ensuring a comfortable temperature throughout your home!
Frequently asked questions
Is it worth investing in a heat exchanger?
Yes, heat exchangers are extremely efficient for their low investment cost. The unit will improve the comfort of your entire home and make it more pleasant to live in. You will also reduce your energy costs by utilizing existing heat.
Where should I place the heat exchanger?
The placement is determined by the model you have purchased. For example, the Airmove 1.1 should be mounted horizontally in the wall between two different rooms. The Airmove 2.0, on the other hand, should be placed between floors to be able to move the heat efficiently.
Why doesn't an Airmove have thermostat control?
A thermostat counteracts a constant flow between floors / between rooms. We have a desire to always have the best indoor climate possible and eliminate large temperature differences, by having an incredibly energy-efficient product that has such low energy consumption that it is largely negligible (26 kWh / year) we have chosen not to develop a thermostat-controlled unit so that you can enjoy the product in summer and winter.
