Air Source Heat Pump Fundamentals

Air Source Heat Pumps Comparison

There are several factors to consider, in addition to the cost, while attempting to select the finest air source heat pump for your house.

Air to Water or Air to Air

Air to water and air to air are the two different forms of air source heat pumps.

Heat is produced from the outside air and transferred to the water in a central heating system using air to water heat pumps.

Air to air heat pumps function more as air conditioners than they do as heaters. They produce heat by transferring outdoor air’s energy to the ventilation system of a building. In order to transport air throughout the building, air to air heat pumps often require a complete installation of an exterior fan unit and a ventilation system. Our ranking of the top air source heat pumps only includes air to water types because they are highly challenging and may be more expensive to install in existing buildings.

Low or High Temperature

The majority of air source heat pump producers provide high temperature and low temperature variants of their air to water pumps. While high temperature heat pumps are better suited to conventional central heating systems because they can supply water at temperatures as high as 75–80°C, which is comparable to a gas boiler, low temperature heat pumps are better suited to homes with underfloor heating or low temperature radiators. In our post on Low vs. High Temperature Air Source Heat Pumps, we go into more detail about how these systems differ.

Monobloc or Split

Most manufacturers provide two different types of air source heat pump units: monobloc and split. Split heat pumps have an interior and outdoor unit, whereas monobloc heat pumps only have an outside unit.

Output Size

There are several (kW) output sizes for air source heat pumps. The output you need will depend on the size of your property, thus these output sizes are crucial. Below are some samples to help you get a sense of what size output you might need:

  • 1 bed apartment or flat – 2-3 kW
  • 2 bedroom terraced home, 4-5 kW
  • 3 bedroom, 6 to 8 kilowatt semi-detached home
  • 4-bedroom home; 9-11 kW
  • 5 bedroom detached home, 12 to 15 kW

These are only estimates that may change depending on a variety of factors.

Global Warming Potential

Refrigerants are a significant component in air source heat pumps. The only component of an air source heat pump that can have a detrimental environmental impact is these gasses. This is because they all have the potential to trigger global warming (GWP). A gas’s global warming potential (GWP) is a measure that describes the greenhouse impact a gas would have if it were released into the atmosphere. The more harmful a gas would be to the environment, the greater its GWP would be (carbon dioxide has a GWP of 1). Below is a table listing the refrigerants used by air source heat pumps and their global warming potentials:


Refrigerant Type Global Warming Potential (GWP)
R290 3
R32 677
R410A 2,088

Product Description

For more than 60 years, the Swedish manufacturer Nibe has been creating home heating systems. Because Nibe air source heat pumps have a strong focus on functional design, as one might anticipate from a Scandinavian company, they are among the simplest and most affordable heat pumps to install.

One of the company’s most well-known products is the F2040 line of air-to-water heat pumps, which is appreciated for its simple installation, low operating temperature, high output, and excellent customer service.

Because it is the best air source heat pump for small- to medium-sized houses, the Nibe F2040 line is quite well known. Because the units themselves are so small, they take up less room on your property. To save room on the floor, they may also be placed on the wall. The F2040 versions also only require 150 mm of clearance space from any adjacent wall that you may mount it against, as well as 1 meter of free space in front of the unit. You have a lot of versatility thanks to this in a small area.

The design’s attention to detail is likewise well-liked. The F2040 is one of the quietest air source heat pumps you can buy, thanks to fan blades that are made to flow air quietly and anti-vibration connections. Additionally, it should provide enough heat, even in cold weather, to warm the typical terrace home, with possibilities ranging from 8.7 to 15.8 kW.

Which Air Source Heat Pump Is The Most Suitable For You?

The great efficiency of the air source heat pump you install will reduce your energy expenditures. It is difficult to select a top air source heat pump among the ones we’ve mentioned, though. There are several aspects of your situation to think about when choosing which heat pump would be ideal for you.

If Your Neighborhood Becomes Really Chilly

The appliance’s ability to function when the temperature decreases throughout the winter is your main worry. Only the Daikin, LG, Samsung, and Hitachi models will operate at temperatures as low as -25°C, whereas the majority of air source heat pumps will continue to function at low temperatures.

If Keeping Costs Low Is A Top Concern

You probably won’t want to spend a lot of money on an air source heat pump if you want to switch to greener energy but don’t want to break the bank. The Samsung eco heating and LG Therma system are the most reasonably priced devices on our list, with the least expensive variants costing 2,400 USD and 2,600 USD, respectively. Compared to the other air source heat pumps on our list, it is around £1,000 cheaper.

If Protecting The Environment Is Critical To You

Making your home more environmentally friendly and energy-efficient is one of the main justifications for switching from a gas boiler to an air source heat pump. Get one of the heat pumps with the lowest global warming potential if this is your only priority (GWP). The Vaillant line of products includes appliances that utilize the naturally occurring R290 refrigerant, which has a global warming potential of 3 (the lowest GWP is 1), making it the greatest option for those devoted to minimizing their environmental effect.

Bigger And Older Properties

For larger houses, the Hitachi heat pump is the ideal option since it can heat water to 80°C to meet the higher demand for hot water for additional radiators and bathrooms. Additionally, it doesn’t need any modifications to an older home’s radiators because existing radiators and plumbing can handle water temperatures of 80°C just fine.

FAQs about Air Source Heat Pump

1. Do air source heat pumps function in the winter?

Air source heat pumps function year-round, including in the cold. An air source heat pump may really collect heat from the air throughout the winter even though you would believe it will only function in the summer. Additionally, they may function as air conditioners, which can assist in cooling your house throughout the sweltering summer months.

2. What benefits can air source heat pumps offer?

In order to heat your home equally, air source heat pumps require four times less energy than a conventional gas boiler. This implies that you might reduce your carbon impact while saving up to 360 USD or more a year on energy costs. Air source heat pumps are also considerably simpler and less expensive to install than ground source heat pumps or even solar panels.

3. What drawbacks are there to air source heat pumps?

Air source heat pumps are still functional in cold weather, but they use more energy since they have to work harder to extract heat. As a result, while you save a lot of energy during the summer while using an air conditioner to offset costs, the efficiency in the winter is less impressive.
