Searching for the perfect heating system? With so many options out there—from gas and oil boilers to electric resistive heaters—it can be really hard to decide which one is the right one for you. But, since you’re here, we’re guessing you’re taking a pretty serious look at an air source heat pump. Did we guess right?

If you’re still debating, we’re here to help! Let’s go through a list of pros and cons to help you make up your mind.

Pros of Air Source Heat Pumps

Let’s start with the good stuff, shall we? Start off on a high note. From efficiency to convenience, there are some good reasons to choose an air source heat pump.

Energy Efficiency

Starting off with a bang with efficiency! Air source heat pumps are renowned for their energy efficiency. The reason these machines are so good at their job is due to how they’re built.

While some systems use combustion, air source heat pumps actually transfer heat. They have a higher coefficient of performance, or CoP. What does that mean? Well, most pumps have a CoP between 3 and 4. That means they produce 3 to 4 units of heat for every unit of electricity used!

That’s awesome! Surely that will lead to some pretty potential lower heating costs. And who wouldn’t love keeping money in their own pocket.

Environmental Benefits

Protecting the environment to the best of our ability is a great approach to take. Using an air source heat pump can help with that. These systems have a lower carbon footprint. How so? They utilise the ambient air, which is already a renewable resource, for heating and cooling!

  • Reduced Greenhouse Gas Emissions: Air source heat pumps can lead to fewer emissions compared to traditional fossil fuel-based systems.
  • Use of Eco-friendly Refrigerants: Many modern units come with refrigerants that have a reduced global warming potential, contributing to environmental conservation.

Versatility and Convenience

Everybody loves some flexibility. I mean, who wants to be stuck in a box, right? An air source heat pump delivers just that. Can you guess how? By providing both heating and cooling! But that’s not all. It also interfaces seamlessly with your existing ductwork and underfloor heating systems. Less work for you sounds like a pretty big pro.

  • Heating and Cooling in One: Switch between modes to stay cool in the summer and cosy in the winter.
  • Free Hot Water: Some models include features to heat water, adding another layer of utility to the system.

Cons of Air Source Heat Pumps

Since we’re riding such a high, we might as well skip over the cons, right? No, no. You need to make an informed decision. We get it. It’s important to consider any limitations that may affect you. Fortunately, our con list isn’t long.

Performance in Extreme Temperatures

The first con on our list has to do with extreme temperatures. Since air source heat pumps depend on the ambient air temperature, they tend to struggle during severe cold spells. This can lead to a reduced heat output. You may find that it ends up needing to work harder to maintain that comfortable indoor temperature.

You can alleviate this problem by using a supplementary heating source. This will, of course, lead to additional costs, however.

Installation and Costs

Like most things, you get what you pay for. There’s no exception in this case. The initial setup for a heat pump can be a bit pricey. These prices can vary by location and the type of unit you choose.

Now, you’re not going to want to skimp on installation, no matter how tempting saving some money may be. Having a professional installation ensures optimal efficiency and lifespan of your system. Search for reputable installers. You may be able to save by finding someone local. For instance, finding someone to install air source heat pumps York or wherever you live.


And there you have it! The pros and cons of an air source heat pump. From efficiency to environmental consciousness, and the issue of extremes and installation costs, there’s a lot to think about. Ultimately, the decision is yours, but now you’re better equipped to make it.
