When do I need a heat exchanger between floors, and why? What can I save?

A heat transfer unit makes it easy to distribute heat between different areas of your home. For example, if you have a fireplace or another heat source in the living room, you can spread some of that heat to other parts of the home.

 

When it comes to multi-story houses, Airmove 2.0 can also spread heat to the upper floor. This is achieved by installing the unit in the floor on the upper level, which has proven particularly effective for older houses.

 

This will ensure that excess heat is not wasted. Instead, it will be used to heat other parts of the home. During the summer months, you can use the unit to transport cool air from an AC unit to create a cooler climate throughout the home.

 

But how does a heat transfer unit work? Where should you place one, and how much money can you save with it? We will give you the answers to these questions and much more in this guide. Therefore, it is best to keep reading so you don't miss out on important information!

Reduce temperature differences between floors

In multi-story homes, temperature differences tend to be a common problem when relying on an airborne heat source. This means that if you use a wood-burning stove, air-to-air heat pump, or direct electric heating, the heat will be distributed via the indoor air.

 

To distribute heat (including cold air) evenly throughout the home, efficient air circulation is crucial. Otherwise, the heat will remain stagnant and concentrated in the space where the heat source is located.

 

In larger houses and homes where the heat source is located on the ground floor some distance from the stairwell, uneven heat distribution is quite common. One way to solve this problem is to install a complementary heat source.

 

Unfortunately, an additional heat source requires significant investment to implement. Therefore, it is considerably more cost-effective to install a heat transfer unit like Airmove 2.0. This heat transfer unit has been designed to create continuous circulation of warm air.

 

This, in turn, will also enable the heating of the upper floor. As you can see in the table below, the average temperature is significantly lower with a heat transfer unit than without between the different floors of the residence:

Ground floor

Works ideally – both in winter and summer

During the winter months, it can be a challenge to transport warm air to the upper floor of the house. By investing in a heat transfer unit, a negative pressure is created that forces the cold air from the upper floor down to the ground floor.

 

This, in turn, creates a negative pressure on the upper floor, while positive pressure is created on the lower floor. When these conditions are met, the warm air from the ground floor will automatically rise to the upper floor.

 

The end result is a significantly more even distribution of heat, including more efficient air circulation. The latter will also reduce the formation of moisture, which in the worst case can lead to mold thriving!

 

During the summer months, the function is reversed. More specifically, this is achieved by circulating cool air to the upper floor by fanning warm air down to the ground floor. This results in efficient air exchange and significantly cooler temperatures throughout the house!

Energy savings with a heat transfer unit

According to the Swedish Energy Agency, many homeowners could save significant amounts by installing a heat transfer unit. To give you an idea of how much you can save with Airmove 2.0, we will next calculate it based on the following:

  1. Percentage savings: Airmove 2.0 provides 25-35% savings.
  2. Electricity price: SEK 1.50 per kWh.
  3. Power consumption: 3W, which corresponds to approximately 27 kWh per year.

Below, we have compiled a table based on figures from both the Swedish Energy Agency and the National Board of Housing, Building and Planning. Based on the figures below, you could save many thousands of Swedish kronor by installing Airmove 2.0!

 

Type of dwelling

Consumption before Airmove 2.0 installation

Savings

Annual savings

Terraced house

15,000 kWh/year

25 - 35%

SEK 5,625 - 7,875

House

Concluding remarks

If you live in a multi-story house with a frequently used heat source, such as a wood-burning stove, a heat transfer unit can save you several thousand kronor per year. We particularly recommend Airmove 2.0 when you aim to spread heat between floors.

 

Based on our calculations and data from the National Board of Housing, Building and Planning, you can save a large portion of your energy costs, depending on the type of dwelling and the existing heat source. Generally, you will save the most money if you live in a detached house, but terraced and semi-detached houses will also see significant savings.

Frequently asked questions

Are heat transfer units really effective?

Yes, by transporting warm air from a central heat source, you can reduce the need for investments in other heat sources. In addition to spreading warm air more efficiently, you can also make significant energy savings!

How do I best spread the heat?

In addition to investing in a heat transfer unit, you also need to focus on other methods. This includes but is not limited to keeping doors open between floors and rooms, arranging furniture so that it does not block vents, etc.

Can I use a heat transfer unit to transport cold air?

Yes, this is useful during the summer months. The concept is based on the same logic, which means you circulate air between floors in the same way you transport warm air during the winter months.
