Air Source Heat Pump - Glow Groip

Why we love Air Source Heat Pumps (and you should, too!)

You’ve probably seen us banging on about Air Source Heat Pumps (ASHP) A LOT over the last few months and that’s because they are literally the way forward in terms of efficiency and helping contribute to a cleaner, greener future.

Last month you most likely saw or heard about the largest report ever to be published on climate change and you’ll all probably agree, it was terrifying. ASHPs are a great replacement for gas heating systems because they don’t use fossil fuels!

You probably know, but in case you didn’t, fossil fuels are B A D for the environment as when extracted from the ground, transported, and burned, they emit a number of air pollutants which contribute massively to the global warming crisis.


“Heating makes up 40% of the UK’s energy consumption with 85% being heated using fossil fuel based natural gas.”

As a heating business we believe we have a responsibility to offer and educate our clients on more sustainable options when it comes to designing their heating systems, so I hope this post will give you a bit more of an insight into why we love ASHPs and have put in place the training and equipment needed to provide this type of installation.

What is an Air Source Heat Pump?

Heat pump is a descriptive term. It’s essentially a thing that pumps heat from one place to another and you’ll all own one without realising it… your fridge! Your fridge is a type of heat pump that transfers heat in the opposite direction (cold to hot) and an ASHP does basically the same thing by extracting heat from outside to heat your home.

The unit sits outside and contains an electrically powered refrigeration mechanism (fancy) with a heat exchanger and large fan. Outside air is extracted and transferred to produce warm water.

Don’t get me wrong, there is obviously A LOT more to it than that, but that’s the basic principle!

What about the noise?

This is a subjective topic! What is considered noisy to one might be quiet to another but any MCS accredited installer, like ourselves, have a method of assessing the noise and there is a general requirement to ensure that any we install complies with a set standard in respect to the proximity of neighbours ect.

Did you know? We have an ASHP installed at our North Hykeham offices so please feel free to come over and take a look at one in action and you’ll hear, in my opinion, how unexpectedly quiet they really are!

Let’s Talk about the RHI

Ok, so what’s the RHI? RHI is the Renewable Heat Incentive which is a financial incentive scheme that pays you for having an ASHP. Brilliant! Not so brilliant that it’s due to end in March 2022 so if you are interested in the scheme, get in touch ASAP!

We’ll be able to calculate how much return you’re likely to get but it’s basically worked out based on how much heat is used over a certain period. Domestic schemes are typically 7 years, hell yeah!

Use the RHI Gov calculator for a quick estimate

Hook, line and sinker

I’ve got you interested. Good. That’s what I was hoping for! But where do you go from here?

Firstly, book in for a free, no obligation discovery call for more information, advice and guidance on the suitability of an ASHP for your home.

We’ll then arrange full heat loss survey, and this is basically an in depth survey to assess the true heat loss at your house and our surveyors can then give you a full proposal and personalised RHI calculations for your consideration.

I really hope this post has been at least interesting and maybe planted the seed in some of your minds that considering an Air Source Heat Pump could be an option for you.
