Let's dive into a topic that's been generating a lot of buzz lately. And a product we deeply care about in our global efforts to combat climate change and switch to greener energy sources.

Air source heat pumps (ASHPs). 

This post looks at something you may not be aware of: air source heat pump cooling. These nifty devices are not just about heating your home anymore. We will look objectively at this use by also mentioning the downsides of a heat pump so you can make an informed decision. Heat pumps will benefit everyone though there are some aspects to consider against your budget. 

Homeowners are asking: 

Can air source heat pumps cool your home too? 

Let's break it all down and see how these versatile systems work during the hotter months.

Air Source Heat Pumps Update 2025

This year, advancements in air source heat pump technology continued and are making these systems more efficient and accessible than ever.

We have overseen the installation of heat pumps integrate seamlessly into smart home systems, offering enhanced control and energy savings. For instance, smart thermostats now optimise both heating and cooling, allowing homeowners to adjust settings remotely while reducing energy waste.

It never ceases to amaze us how heat pumps continue to gain popularity as homeowners are clearer on the long term pros like improved fan convectors and insulated pipework have made cooling through air-to-water systems more viable.

With government incentives like the Boiler Upgrade Scheme (BUS) continuing to support installations, adopting heat pumps has become increasingly cost-effective. These innovations reinforce air source heat pumps as a sustainable choice for UK homes.

And we expect another exciting year in 2026 for air source heat pumps.

How Air Source Heat Pumps Work

These systems work through the process of heat transfer. When it's cold outside, ASHPs extract heat from the air and transfer it inside, even if the outside temperature is low. 

To cool your home, the process reverses. The ASHP extracts heat from the inside of your home and expels it outside. Think of it as a two-way street for heat. This dual functionality makes ASHPs a flexible option, especially if you're looking for year-round comfort.

Air-to-Air Heat Pumps

These are the most common types for both heating and cooling. They work by circulating air, similar to how an air conditioner functions.

Benefits of Air-to-Air Systems

Reversibility: These systems can switch between heating and air source heat pump cooling efficiently. It's like having a heater and an air conditioner rolled into one.

Efficiency and Speed: Air-to-air units quickly cool your home by circulating cool air.

Downsides

While air-to-air heat pumps sound great, they do have some limitations, particularly here in the UK. For one, they aren't covered by the Boiler Upgrade Scheme (BUS) grant, making them a bit of an upfront investment. 

If your home already has a traditional water-based heating system, retrofitting for an air-to-air heat pump can be pricey. Plus, you'll still need another system to heat your water. 

Given the UK’s mild climate, the necessity for cooling isn’t as pressing, and some might find this overkill for the few truly hot days we get.

Air-to-Water Cooling

Here’s another option for you, air-to-water heat pumps. These are typically used for heating your home through underfloor heating or radiators, but they can also provide cooling under certain conditions.

How It Works

Air-to-water heat pumps can cool your home by circulating chilled water through pipes. However, there are a couple of catches. Traditional radiators and underfloor heating systems aren't very effective at cooling.

Requirements

Fan Convectors: To make the cooling feature work, you’d need fan convectors that can circulate cool air efficiently.

Insulated Pipework: All pipes need proper insulation to prevent condensation, which can lead to damp issues. Nobody wants that.

Alternatives to Air-to-Air Heat Pumps

You can modernise your existing system by switching from gas to an air-to-water heat pump. This offers a balanced way to maintain your comfort levels without going overboard.

Efficiency: Higher efficiency can mean lower energy bills.

Dependability: Reliable heating and zero carbon tariffs make this an attractive choice.

Government Incentives and Grants

The UK government offers various grants to encourage energy-efficient home improvements. The Boiler Upgrade Scheme (BUS) is one such scheme aimed at reducing the cost of installing low-carbon heating systems like air source heat pumps.

Details

Eligibility: Make sure you check if you're eligible for the BUS grant or other incentives. This can significantly offset initial costs.

Potential Savings: Grants can save you thousands, making it easier to adopt these air source heat pump cooling technologies.


Did you know how well heat pumps run radiators?

So, can air source heat pumps cool your home?

Absolutely, they can. However, the best type of ASHP for you—air-to-air or air-to-water—depends on your unique needs and current heating setup. While the initial investment may be considerable, the long-term benefits such as energy efficiency and dual functionality make it worth considering.

Before making any decisions, consider consulting with a professional at S Fearn Plumbing & Heating to assess your specific requirements. We can provide tailored advice and help you figure out the most cost-effective and efficient solution for your home.

A couple more points worth a mention...

Smart Home Integration

In today's digital age, integrating heat pumps with smart home systems offers additional benefits.

Smart thermostats can learn your habits and adjust the temperature accordingly, optimising the cooling efficiency of your heat pump.

This means you can enjoy a consistently comfortable home without wasting energy. Smart systems enable remote access, allowing you to control your home's cooling needs even when you're away.

This level of control not only enhances convenience but also contributes to energy savings.


Environmental Benefits

Using heat pumps for cooling is not just an efficient choice; it's an environmentally responsible one.

Heat pumps reduce reliance on fossil fuels and lower your carbon footprint. By fulfilling both heating and cooling requirements, they offer a sustainable alternative to traditional systems.

This aligns with global efforts to combat climate change and promotes a greener future.

FAQs on Cooling Homes With Air Source Heat Pumps

A person standing in front of a group of question marks FAQs on heat pumps

Can ASHPs completely replace air conditioning units?

While they can serve a similar function, ASHPs may not be as powerful as dedicated air conditioning units, especially during extremely hot days.

How energy-efficient are ASHPs in cooling mode?

They are quite efficient but can lose some effectiveness in very hot climates. In the relatively mild UK summers, they perform well.

Are there any specific maintenance requirements for ASHPs used for cooling?

Regular maintenance, such as cleaning or replacing filters and ensuring coils are clean, will help maintain efficiency and extend the life of the unit.

How do air source heat pumps utilise thermal energy from the air?

Air source heat pumps extract thermal energy from outside air, even in cold conditions, and convert it into heat for home heating and hot water.

How do heat pumps provide a cooling system in addition to heating?

Air source heat pumps can reverse their operation to provide an efficient cooling system. In cooling mode, they extract heat from inside the home and transfer it outside, effectively lowering the indoor temperature.

 

And there you have it! 

If you’ve been pondering over the pros and cons of air source heat pumps, hopefully, this guide has given you a clearer picture. 

Their ability to cool your home can be a significant advantage, provided you weigh the initial costs and specific requirements. Keep pushing forward, and here’s to a cooler, more energy-efficient home!
