Understanding air source heat pumps

Noise

You might be surprised by just how quiet an air source heat pump is.

Like any machine in operation, air source heat pumps do produce noise – it’s about the same as a whisper, the gentle hush of a library, or the sound of a breeze through leaves.

Radiators

Do I need to replace my radiators? It’s a question we hear a lot and it’s an important one. Identifying whether your current radiators are suitable for a heat pump is part of our extensive design process. We’ll answer any questions you’ve got and help you with all the you need before going ahead but don’t worry, we’ll guide you every step of the way.

Efficiencies

We rarely have bitterly cold winters here in the UK.

Your air source heat pump is perfect for the UK climate as it can work off-grid and will still operate when outside temperatures are as low as -28°C. It may work a little harder but you will still be warm and cosy in your home.

Frequently asked questions

What is a heat pump?

Air source heat pumps (ASHP’s) are an innovative, highly efficient, renewable energy system. They heat your home and hot water using energy from the air outside even in the depths of winter. They are quiet, easy to use, and don’t need much maintenance once installed.

You can read an in-depth article about heat pumps here.

How much will a heat pump cost?

Every heat pump installation we carry out is specific to your home and your personal requirements. There are a wide range of factors that need to be taken into account before we can give you a dedicated quote. What we can say is that alongside the £7,500 Boiler Upgrade Scheme (BUS grant) and any eligible finance options, a complete heat pump system, matched perfectly to your requirements as part of our bespoke system design service and fully installed, could be a lot closer than you think.

Many customers find this a reasonable level of investment for a dependable, robust, and eco-friendly heating system that will keep them warm for years to come. You can find the BUS scheme eligibility criteria here, but we handle all the paperwork and applications, so it won’t be something you’ll have to worry about!

Will a heat pump lower my energy bills?

Installing an air source heat pump is a great start to lowering your energy bills.

You should also consider the following:

  • Changing your electricity tariff to a dedicated heat pump tariff
  • Installing solar panels and batteries on your property
  • Ensuring your property is well insulated

You could save up to £290 a year on your energy bills if replacing an old G-rated gas boiler – and could see comparable energy bills if replacing a new A-rated gas boiler.

Will I need new radiators?

Not always, no but the performance of your heat pump system hinges on the compatibility and efficiency of your radiators.

Larger radiators with convectors are generally the best choice as they have a larger surface area. Careful evaluation and measurement of your existing radiators will ensure that your heating system operates at its best, providing comfort and energy efficiency.

We've written an extensive guide to Heat Pumps and radiators here.

Are heat pumps noisy?

If you’re concerned about how loud an air source heat pump is, you might be surprised to instead find out how quiet they are.

Like any machine in operation, heat pumps do produce noise – but how much noise they produce is remarkably low, especially with newer ASHP models designed with a focus on low-noise operation.

The noise is so low that it’s about the same as a whisper, the gentle hush of a library, or the sound of a breeze through leaves.

But if you’re curious to learn how a heat pump produces noise and how much noise it produces, read on.

Are heat pumps efficient?

Air source heat pumps are one of the most efficient heating systems for your home. Generating three times the amount of heat for every kw of energy used. Heat pumps are sustainable, low carbon and help you save energy.  

Our in-depth article on Heat Pump efficiency can be found here.

Will a heat pump keep me warm in winter?

While we rarely have blazing hot summers in the UK, we also rarely have bitterly cold winters. 

Your air source heat pump is perfect for the UK climate as it can work off-grid and will still operate when outside temperatures are as low as -28°C. It may work a little harder but you will still be warm and cosy in your home.

How much room will a heat pump require?

You’ll need to have space for the heat pump unit to be installed outside of your home. 

This may be more challenging if you live in an apartment building. However, there is a lot of freedom over where we can put the unit if you have space. Remember, you will also need space for a hot water tank.  

A well-designed and installed system will take all of this into account so you get the most out if your new air source heat pump.

Our Consultants will be able to answer any questions you have.
