Air Source Heat Pump Cooling: Can Heat Pumps Cool Your Home?
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.
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.
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.
FAQs on Cooling Homes With Air Source 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.
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!
