  • Heat Pumps VS Air Conditioners 

Updated: August 24, 2024

When you want to get a new heating or cooling system, it is better to know what options you have available on the market. Knowing what heating or cooling system is suitable for your home can help you make the right decision.

On this blog we’ll explore the differences between heat pumps and air conditioners. We’ll talk about how both systems work, which one is more energy efficient and which one is more cost effective. 

How do heat pumps work?

Heat pumps transfer heat from outside your home into the inside during winter and vice versa in summer months. Heat pumps use electricity in order to move heat from a cool space to a warm area. So they have the ability to make your home warm in winter and cold in summer.

And to enhance comfort in your home, heat pumps can also dehumidify indoor air. Two main types of heat pumps are available:

Air source heat pumps

Air source heat pumps work by transferring the heat from the outside air (even in cold weather) and moving it inside to make your home warmer. A heat pump can absorb the heat and compress it in order to increase its temperature. This warm air is then circulated throughout your home to provide heating or hot water. 

The best thing about heat pumps is that they use so much less electricity than traditional heating systems. In short, they are cost-effective as well as eco-friendly.

Ground source heat pumps

A ground source heat pump, on the other hand, works differently by harnessing the natural heat stored in the ground. This can be achieved by burying pipes that contain water and antifreeze in your garden or under your house. This antifreeze liquid can absorb heat from the ground and transfer it into your home. This heat will be used to warm up your underfloor heating, radiators or hot water system. 

Ground source heat pumps can be more efficient because the ground has a relatively stable temperature throughout the year. That is why they are both eco-friendly and reliable.

How do air conditioners work?

Air conditioners work by using refrigerant in order to absorb heat from inside your house and release it outside while pumping cold air into your home. What is more, many air conditioning units can be reversed into providing heating in colder months.

Air conditioners mainly focus on cooling indoor air. That is why they are a perfect choice for long and hot summer days. And just like heat pumps, they can also dehumidify and purify the air in your home. 

Heat pump installation 

Heat pumps can be complicated to install, especially ground source heat pumps. As has been stated before, ground source heat pumps include pipes that should be buried underground. That is why a professional and well trained HVAC technician should be hired. 

Air conditioners installation

Air conditioners are easier to install than heat pumps. That being said, a professional installer is still required in order to ensure that your system is working efficiently and safely. 

How efficient is a beat pump?

Heat pumps are quite efficient due to the fact that they move heat from one place to another without generating it. That is why they are a great option for people who are looking to reduce their carbon footprint. 

How efficient is an air conditioner?

Air conditioners are efficient at cooling. However, they are less efficient than heat pumps in the long run. 

How green are heat pumps?

A heat pump has a lower carbon footprint because it can utilise existing heat instead of burning fuel to make it.

How green are air conditioners?

Air conditioners, particularly old models, are not very efficient and can contribute to greenhouse gas emissions. This is due to the increased amount of energy these old models consume. 

How long can heat pumps last?

Heat pumps can be used all year round. With regular maintenance and servicing, they can last as long as 20-25 years.

How long do air conditioners last?

Air conditioners also require regular maintenance and servicing to ensure efficiency and longevity. A well-maintained air conditioner can last between 15-20 years.

What are the advantages of heat pumps?

Efficiency

When it comes to efficiency, we can easily say that heat pumps are quite efficient. Instead of generating heat, they just move it from one place to another. A heat pump produces lower carbon emissions so it is an environmentally friendly heating option. 

Year-round operation

Heat pumps can heat your home during winter and some models can also cool it during summer. So they aré useful in all seasons. 

Lower energy bills

Heat pumps can significantly lower your energy bills and save you money because of their high efficiency ratings. 

Long lasting

Heat pumps can last for many years, granted that they are regularly maintained. 

Safety

Since heat pumps don’t require running on any flammable fuel, they reduce the chances of accidents taking place.
