A variation in indoor temperature is not uncommon. This often results in some rooms feeling significantly colder than other parts of the home. To get rid of this problem, you need to effectively circulate air between adjacent spaces.
With the help of a heat exchanger (also called an air exchanger), heat is efficiently distributed from room to room. This in turn results in a more even indoor temperature in the home. At the same time, there is a lot of money to be saved by making use of the existing heat.
Are heat exchangers a good investment?
Yes, a heat exchanger is usually a really good investment when you want to improve the distribution of heat in your home. The basic concept of an air exchanger is to transport excess heat from warmer to cooler parts of the home, while achieving the following:
● Save energy by reducing the need for supplementary heating.
● Increase comfort and coziness in the household by eliminating the occurrence of cold spots.
.
By investing in a heat exchanger, you will also be adopting a more environmentally friendly lifestyle. This is achieved by optimizing the use of existing heat, which in turn reduces the need for more energy. Ultimately, this will result in a lower climate impact.
How much can I save?
A heat mover can be extremely effective when it comes to distributing indoor heat. If you have a heat source such as an air source heat pump, you can complement it with an air mover. This will save some energy because you don't have to run the heat pump at the highest level.
If you also happen to live in a villa from the 70s or 80s, which also relies on exhaust air via the toilet and/or kitchen - where the supply air comes in via natural draft valves, you can save even more money.
Based on data from the Energy Market Inspectorate, you can save up to 30% on your heating costs by investing in ventilation with heat recovery / circulation. This also means that you don't have to supplement it with other energy-consuming heat sources.
Below we have prepared a table with statistics from the Swedish Energy Agency's knowledge bank that indicates how much you can save in energy costs for an average Swedish home.

How does a heat exchanger work?
The main purpose of a heat exchanger is to move cold air from one room to another.
Constant circulation evens out the temperature in a good way.
This is achieved via a discreet fan that sucks in cold air and then channels the air to adjacent rooms, thus circulating the air.
The unit can be installed in floors or walls - depending on your floor plan. A model that has Airmove 2.0, for example doesn't even need sensors but is developed to maintain circulation between floors in summer and winter to always strive for an even temperature in the house.
This in turn means that the heat exchanger is always working, which also saves valuable energy.
That's why Airmove 2.0 has been designed to be quiet. This makes the heat mover ideal for bedrooms, for example, where even the slightest noise can be disturbing. In addition, the unit is easy to maintain, which ensures a long service life.
What is meant by air circulation between rooms?
Heat exchangers like Airmove 1.1 have been designed to optimize the airflow between different rooms in a house, for example in single-storey villas. This helps to create a more balanced indoor climate, regardless of the of where in the home the heat source is located.
How much does a heat exchanger cost?
The price of a heat exchanger is based primarily on the model.
However, creating the conditions for an even indoor climate doesn't have to cost a fortune. However, expect a price range of 2000 - 3000 SEK.
Although the initial investment may seem a bit high, it will be worth it in the long run. Given the skyrocketing energy prices, you will often get your investment back within a few months.
Our air movers, such as Airmove 2.0 and Airmove 1.1 , have been designed to be installed by the average person. This means that even if you don't consider yourself particularly handy, you will be able to install the heat mover on your own. A video guide on how to install it can easily be found on our Youtube channel.
How do I get the heat up to the upper floor?
Moving heat from the lower floor of the house to the upper floor can be a real challenge. During the winter months, it is often difficult to get an even distribution of the warm air to the upper floor.
By investing in a heat mover like Airmove 2.0, you will create negative pressure in the upper level of your home. This is achieved by transporting the cold air from the upper to the lower part of the home.
When this happens, a negative pressure will be created on the upper floor, while a positive pressure will be created on the lower floor. The former will result in the warm air from the lower floor moving up to the upper floor.
During the summer months, the function will be more reversed. More specifically, this means that air is moved upstairs via the heat exchanger and then down to the downstairs. The air exchange also promotes a more balanced temperature throughout the home.

Closing words
Investing in a heat exchanger can be one of the best decisions you can make. Modern products like Airmove 1.1 and Airmove 2.0 make it possible to create conditions for a more even temperature throughout the house.
At the same time, you will save both money and energy, which will further convince you of your choice. Regardless of whether you currently heat yourself via an air source heat pump, wood-burning stove or similar, a heat exchanger is ideal for a more even distribution of heat.
Frequently asked questions
Can a heat exchanger reduce the risk of mold formation?
Yes, a heat exchanger helps to even out the temperature and reduce the formation of cold spots. This reduces the risk of condensation forming, which in turn prevents mold.
What are the main environmental benefits of installing a heat exchanger?
The main environmental benefit is that heat exchangers reduce energy consumption by utilizing existing heat. This in turn leads to lower carbon emissions and a more sustainable home.
Can I use a heat exchanger in combination with a solar heating system?
Yes, a heat exchanger can efficiently spread the heat generated by solar heating to other parts of the home. This makes energy consumption more efficient, which also means that you get more benefit from the sun's energy.
