Pros and Cons of Air Source Heat Pumps

Is an Air Source Heat Pump Right for You?

Do you own a gas or electric heating system? Do you receive high energy bills? Have you considered switching to a more eco-friendly source, such as an air source or ground source heat pump? Here you will find information about the real advantages and disadvantages of such a transition.

What Is An Air Source Heat Pump?

An air source heat pump works by transferring heat absorbed from the outside air to an indoor space such as an office, home or a building via the wet central heating systems to heat radiators and provide hot water. It works like a refrigerator. Air source heat pumps can also work as a cooling system in the summer months. Air source heat pumps are usually placed outside of a home, office or building where there is adequate space.

There Are Two Main Types:

  • Air-to-air heat pumps - absorbs heat from the outside air and then transfers it directly into your home via a fan system to heat a room or an indoor space.
  • Air-to-water heat pumps - absorbs heat from the outside air and then transfers it via your central heating system to provide both hot water heating and heating for an indoor space.

Advantages of Air Source Heat Pumps

After thorough research and examination of air source heat pump reviews, here you will find significant advantages of purchasing an air source heat pump:

  • Heat Pumps provide a low carbon footprint 
  • Air source heat pumps can alternatively be powered by wind energy or solar power instead of electricity
  • An air source heat pump can deliver heat at a lower temperatures at -20 C compared to conventional oil and gas boilers
  • You could potentially receive payments by producing your own heat through the UK’s Renewable Heat Incentive
  • Can heat hot water for immediate or later use

Disadvantages of Air Source Heat Pumps

The main air source heat pumps disadvantages associated with air source heat pumps are listed below:

  • This type of Air Source heating lowers heat supply compared to oil and gas boilers, so larger radiators would be needed
  • They perform better with underfloor heating or warm air heating and work more efficiently when coupled with larger radiators
  • Air source heat pumps are not the best option if you live on gas mains
  • They need electricity to be powered if there is no access to solar energy or wind power
  • You would need a highly insulated home to reap the high energy savings benefits
  • Noisy like an air conditioner when it is running
  • Less efficient in winter due to low Coefficient of Performance (COP) levels 

What to Take Into Account Before Installing an ASHP

When thinking about installing air source heat pumps, one must consider two main factors:

  • Costs: The cost of installing an air source heat pump is usually between £3,000- £11,000. N.B: Additional costs may be incurred depending on the size of your property and your specific requirements.
  • Insulation: Air source heating is highly useful if followed correctly. To have a high return in terms of saving from purchasing and using an air source heat pump it is important to have a well-insulated home, with especially loft insulation. This makes sure that the heat generated within the home does not escape, thus allowing for a consistently warm home during the winter.
