The Homeowner’s Guide to Heat Pump Installation

the homeowner's guide to heat pump installation

Heat pumps are redefining how we heat and cool our properties, allowing homeowners to reduce their carbon footprints and save money on utility bills. 

According to research from the University of Oxford, the supply of fossil fuels will likely be depleted by 2060, making renewable energy integral to the future. 

The UK government aims to become one of Europe’s largest markets for heat pumps in the near future, and homeowners can take advantage of initiatives that allow them to save money on installation (Heat Pump Investment Roadmap). 

In our homeowner’s guide to heat pump installation, we’ll reveal everything you need to know about integrating one of these sustainable solutions into your property. 

Let’s jump straight in. 

Choosing your heat pump 

Before considering the installation process, you’ll need to decide which type of heat pump you’ll invest in. The main pumps available in the UK are air-source, water-source, and ground-source, but not all will be compatible with your property. 

Each offers unique benefits, but your choice will depend on your budget and whether you’re prioritising convenience or functionality. 

Air-source pumps 

Air-source heat pumps are the most popular option in the UK, as they’re easy to install and the property won’t require any adaptations. They usually come as an outside unit and use a compressor and refrigerant to extract and distribute outside air into the property. 

If you’re looking for a convenient solution that won’t require much space, air-source pumps are ideal.

Ground-source heat pumps 

Ground-source pumps utilise the earth’s stable temperatures to generate reliable heating and cooling for properties. Installation is more complex, as a horizontal or vertical pipework system has to transfer the heat to the pump. 

Ground-source pumps take longer to install but can be more consistent. These pumps can be a wise investment if you have extensive outdoor space. 

Water-source pumps 

Water-source pumps are renowned for their consistent performance, but they’re not suitable for all properties. These pumps need a water source, such as a river, stream, or lake, to function, and the installation is often more complex than that of air or ground-source pumps. 

While water-source pumps can be more expensive to install, their consistency means most homeowners get their money back through lower energy bills. 

Determining your eligibility for financial support 

As we move towards more sustainable energy options, the UK government is offering homeowners the opportunity to save money by making eco-friendly decisions. 

The UK Heat Pump Grant gives homeowners up to £7,500 when installing a pump, reducing the costs and making them more accessible. Before buying a pump, it’s important to look at the eligibility criteria in place, which states: 

  • The property has to be in England or Wales (Scotland and Northern Ireland have separate initiatives). 
  • You must own the property – including Buy to Let properties and second homes. 
  • The heat pump must replace a traditional fossil fuel system. 

You can apply for a grant and receive a significant discount if you meet the above requirements. 

The installation process

Installing a heat pump is an excellent way to cut down your energy bills, but it’s always best to have it done by a professional service. Specialists will ensure nothing goes wrong with the pump and offer ongoing support. 

Our Heating and Solar Plans offer heat pump installation, repairs and services for a convenient monthly fee, saving you a lot of time and money. 


Your installation service will visit the property and inspect it to assess whether it’s suitable for a heat pump. They’ll also look at your garden and whether the property is near a water source to determine which pump will be best. 

Most households choose an air-source heat pump due to its convenience and accessibility, but ground-source and water-source installation is also available if your home can accommodate the pumps. 

Installing the heat pump 

The technician will remove your existing heating system and dispose of the boiler without causing environmental damage. They’ll then choose an appropriate area for the outdoor unit and set up your indoor units. 

Once the units are installed, they’re connected to an underfloor heating system or radiators to ensure the heat pump can supply them with energy. The last installation step is connecting the indoor and outdoor pump units. 

Post-installation checks 

After the installation, the service will perform final checks, ensuring everything works properly. 

Most installations take two to five days, but if you’re using a water-source or ground-source pump, they can take longer, as the installer will need to perform additional work. 

To DIY or not to DIY

Many wonder if they can save money by installing a heat pump themselves instead of relying on a professional service. While it might seem like a good idea, heat pumps are complex systems that require specialist knowledge. 

Installing it yourself could damage the components, voiding the warranty and forcing you to pay for a new unit. Also, boiler removal could pose risks to your health, including severe burns. 

A professional service will remove the existing boiler safely and ensure the heat pump functions correctly, giving you peace of mind. 

Are heat pumps easy to maintain?

The great thing about heat pumps is that they’re a long-term solution that reduces your energy bills but doesn’t require much maintenance. Opting for a plan that includes installation and services means you don’t have to worry about constantly checking the heat pump. 

A specialist will visit your property to perform incremental checks and make any necessary repairs. With regular maintenance, heat pumps should last for around 25 years, making them an excellent investment.

Installing a heat pump is a positive step forward in the battle to save our planet. As we continue to deplete fossil fuels, heat pumps will become a go-to for homes across the UK, helping people save money and reducing our reliance on non-renewable resources. 

Taking advantage of the government’s grant and opting for a specialist installation service gives you convenient monthly payments with ongoing support. Hometree can help you choose the right pump for your needs and enjoy a seamless installation process.
