Comparing Air Heat Pumps and Gas Furnaces

Air heat pump (Luftvärmepump)are now becoming popular amongst homeowners because they’re energy-efficient and an excellent alternative to traditional heating systems. Unlike other heating systems, air heat pumps don’t create warmth. Instead, they absorb heat from the air and redistribute it into your home. This process is done using a refrigerant system that works similarly to an air conditioner.

Are you curious to learn more about air heat pumps? In this article, we’ll cover the basics of understanding air heat pumps and how they work.

How Air Heat Pumps Work

Air heat pumps use a process called the refrigeration cycle to heat your home. The process starts when the outdoor unit pulls in air from outside your home. This air passes over the outdoor coil, where it absorbs heat from the refrigerant that’s inside the coil. The warm refrigerant gas is then sent through the compressor, which turns the gas into a high-pressure gas.

The high-pressure gas then travels to the indoor unit, where it passes over the indoor coil. The heat from the refrigerant transfers to the cooler air in your home, which then moves throughout the ducts. The refrigerant then converts back into a low-pressure gas and goes back to the outdoor unit.

Types of Air Heat Pumps

There are two types of air heat pumps: air-to-air and air-to-water. Air-to-air heat pumps are the most common and function as previously mentioned, taking heat from the outside air to distribute warmth throughout your home.

In contrast, air-to-water heat pumps are less common, but they function similarly, but they take heat from the outside air and distribute it through water to heat radiators or underfloor heating.

Advantages of Air Heat Pumps

There are several benefits of using air heat pumps. Here are a few to consider:

Energy-Efficient: Air heat pumps are known for their energy efficiency and can reduce your energy bills compared to traditional heating systems.

Flexible Installation: Air heat pumps are easy to install, and with proper maintenance, they can last up to 20 years.

Environmentally Friendly: Air heat pumps generate less carbon emissions than gas boilers or electric heating systems, making them a great choice for homeowners who want to reduce their carbon footprint.

Considerations before Choosing Air Heat Pumps

Before installing an air heat pump, there are a few things to consider. Here are a few:

Climate: Air heat pumps are dependent on temperatures outside, meaning they’re not always effective during extremely cold weather conditions. If you reside in a cold climate, consider an alternative supplemental heating system.

Space: You need to have enough space to accommodate the indoor and outdoor units.

Installation Cost: Finally, you should understand the installation costs before purchasing an air heat pump, as they typically cost more than traditional heating systems.


In conclusion, air heat pumps are a fantastic alternative to traditional heating systems that provide energy efficiency, flexibility, and environmental friendliness. Understanding the basics of air heat pumps and how they operate is an excellent step towards making an informed decision before buying one. Remember that before deciding on an air heat pump, you should consider the costs, installation requirements, and climate of your environment. If it meets your requirements, air heat pumps can be a great choice for keeping your home warm and comfortable.
