Air heat pumps

An Introduction to Air heat pumps

In simple terms, an air heat pump is a device that draws heat from the air in the outdoor environment, even in winter, and circulates that warmth into your house. However, it should always be used as a complementary source of heat and not the main source.

The same system can also do the reverse and remove heat from the house in summer. If you are experiencing high temperatures, you can also cool the inside of your house using an air heat pump system. They offers home owners many different benefits. Here are a few important features to consider.

  • The system comes in two parts – an exterior and an interior section
  • Works as an additional heat source in winter
  • Can act as an air conditioner in summer

How does an air heat pump work?

The technology behind the air heat pump is quite simple. The system comes in two parts. One part is placed outside. This draws in air through a fan. The air passes through a refrigerant gas to the inner part. This inner part distributes the warmth. The amount of heat produced depends on several factors:

  1. The external air temperature
  2. The efficiency of the pump

How long does an air heat pump last?

Depending on the type of air heat pump you get and the engine that powers it, it is generally believed that a standard pump can last as long as 20 years. The good thing about these products is that they do not require high maintenance. However, by taking some simple measures, you can improve your heat pumps lifespan.

  • Use a cover for the external section to protect it from extreme weather conditions
  • Clear debris and leaves from the outer part regularly
  • Clean the fan regularly

Since the system has few moving parts, you do not necessarily need to open up the parts to do routine cleaning too often. However, in many cases, the outer part of the pump will require more frequent maintenance due to the fact that it is exposed to extreme elements all the time.


The mechanism is similar to that of refrigerators. Temperature conversion is achieved when the system pumps a refrigerant through the heat pump’s coils. During the process of heating, the liquid refrigerant boils into vapour or gas. A compressor then increases the temperature of the gas and passes it to a condenser which distributes the heat.

Benefits of air heat pumps

Since air heat pmps is mostly a complementary system, you might be wondering why you should invest in it. One of the benefits is that the installation is simple and the initial investment cost is low. The AHP serves as an additional heating source and air conditioner, reducing overall energy usage, saving money on heating bills.

  • Environmentally friendly
  • Also purifies the air in the home

When you consider what air heat pumps can offer and how little space is required to install the system, you will understand why many people decide to install an AHP alongside their main heating source. The durability is also a very crucial aspect to look at, especially in comparison to other heat sources available.

Choosing the right air heat pump

There are several factors to consider when you want to install an AHP in your house. Different models are produced to meet different requirements. Some of the things to consider include the capacity of your main heating source, the lowest temperature you experience and also how much you wish to invest.
