Finding the best types of heat pumps can be challenging, which is why we’ve relied on a few different sources when reviewing and comparing different options.
Power output is one of the most important things you can consider when it comes to choosing the right air source heat pump. Most heat pumps have an output between 4 and 16 kW, and this is the measurement that tells you how powerful they are. The bigger the home or space you want to be heated, the higher the output should be.
When comparing the best air source heat pumps, you should take into account the size of the space or home, and take the power output into consideration when choosing the right one.
The efficiency of an air source heat pump is essential, and it is measured by the heating seasonal performance factor. In other words, the total heating output during the season is divided by the electricity the heating unit consumes.
Typically, the best air source heat pump is around 300% efficient, but this can vary based on the company and the model. Some air source heat pumps can even be up to 600% effective.
Years of experience
Of course, when choosing the right brand, you want to pay attention to their years of experience. The longer the company has been on the market, the more time they have had to encounter errors and problems, thus having had more time to fix them and optimise their products.
A great example of experience is Samsung, which does not necessarily specialise in air source heat pumps, but has been in the market of technology and appliances for a very long time. So, the name Samsung is well-known and reliable, and you will know that should any problems arise, they will know how to fix them.
Typically, heat pumps produce noise of about 40-60 decibels when measured from a distance of one metre away. Air source heat pumps can be louder than some air conditioning units, which is why comparing the noise levels is also essential.
After all, you want to ensure that you are comfortable with the sound levels that your new air source heat pump produces.
The weight of air source heat pumps varies a lot between models and brands. However, the typical weight starts from about 60 kilograms. In other words, moving an air source heat pump is not easy, and you should have a professional install it.
The weight does factor in when deciding to buy an air source heat pump, but if you are not planning to move it around a lot, it should not necessarily be your first criteria.
The prices of heat pumps vary. Typically, even the most affordable ones start from about £3,000 and the price can go up to £10,000. Usually, the most powerful units cost the most, but other features affect the price, too.
It is important to take pricing into account, but also consider the potential longer term savings to be made on energy bills from installing an air source heat pump. Comparing prices and available features of air source heat pumps is essential so you will get the best value for your money.
Most air source heat pumps come with a limited warranty. Typically, the warranty is about 5-7 years, but it can vary and should be checked before the purchase.
