What is a heat pump and why use them?
A heat pump is a two-in-one system that transfers heat from one place to another using a compressor and a circulating structure of liquid or gas refrigerant. Not only is it a great heating and cooling tool but it is also a good way to save money on your energy bills.
How does a heat pump work?
A heat pump utilises a process of moving heat from the outside to the inside. The heat pump diagram below gives a clearer picture of how a heat pump operates. Here’s how it happens in 6 steps:
- Absorbing heat from outside: A heat pump collects warmth from the outside, which it uses to turn refrigerant, in its pipes, into vapour.
- Bringing heat inside: The gathered vapour is compressed to heat it further, and transported into your home, releasing heat.
- Releasing heat indoors: The super-hot gas passes its heat to your central heating system, warming up the area. During this step, the vapour transforms back into a liquid.
- Cooling down liquid: This liquid passes through a special valve, rapidly cooling it down to prepare for absorbing the outside heat.
- Optional cooling: Alternatively, the heat pump can reverse the process. It takes warmth from the inside and releases it outside, similar to opening a window to let out warm air.
- Continuous cycle: The heat pump maintains a repeating cycle, either bringing warmth in to heat your home or moving warmth out to cool it down.
Types of heat pumps
There are three heat pump types: ground-, air-, and water-source heat pumps. When the heat source is the soil, we talk about ground source heat pumps. Similarly, the ones using the ambient air or a body of water are called air source and water source heat pumps, respectively.
Read more about the specific heat pump types below:
Hybrid heat pumps are another popular heat pump option for homeowners with high heating demands. A hybrid heat pump, also called a dual fuel system, works by switching between the two energy sources (a heat pump + boiler combo) based on the season, temperature, and function needed for maximum efficiency and effective heating and cooling.
An average hybrid heating system costs anywhere between £7,000–£15,000 and around £6,000 to have it installed.
How much do heat pumps cost?
Air source heat pumps costs usually start from £5,000 and go up to £18,000, while ground-source heat pump costs are typically between £13,000 to £35,000 but can reach up to £45,000. The running costs ofheat pumps in the UK depend on your household, its insulation properties, and size.
| Heat pump type | Installation costs | Avg. yearly running costs |
|---|---|---|
| Air source | £8,000–£18,000 | £1,360 |
| Ground source | £14,500–£45,000 | £1,050–£1,650 |
| Water source | £6,000–£11,000 | £1,300–£1,700 |
These are just approximate prices. Wondering about heat pump costs for your specific needs? Avoid the lengthy search for an installer by using GreenMatch.

Heat pump efficiency
How efficient are heat pumps? Heat pumps stand out with their potential for up to 400% efficiency through heat energy recycling from air, water, or the ground. Due to this, heat pumps exhibit significantly higher efficiency compared to traditional heating methods like gas boilers or electric heaters. On average, boilers can offer up to 92-100% efficiency, and electric heaters are theoretically 100% efficient.
| Heating system | Efficiency |
|---|---|
| Heat pump | 300-400% |
| Boiler | 99-100% |
| Electric heater | 100% |
Are heat pumps worth the investment?
Heat pumps represent a smart investment in the long run. Given that you can save on your energy bills and the government can provide you with financial support, heat pumps are absolutely worth it.
With the new heat and buildings strategy coming up, it is expected to further increase the installation of various heat pumps as a low-carbon heating solution.
| Size of a house | Heat pump size (kW) | Energy needed (kWh) per year | Yearly savings | Break-even point (years) |
|---|---|---|---|---|
| 2 bedrooms | 6 | 8,000 | £400–£800 | 7-14 |
| 3 bedrooms | 8 | 10,000 | £500-£1,000 | 7-14 |
| 4 bedrooms | 10 | 12,500 | £600–£1.200 | 7-14 |
| 5+ bedrooms | 12 | 15,000 | £700–£1,400 | 7-14 |
And, depending on your current situation, the repayment time can be drastically shorter than the lifespan, making it a worthy investment. Even though the consensus is that heat pumps are a good investment, this doesn’t mean that you should overpay on the upfront costs.

What are the pros and cons of heat pumps?
Let’s take a look at the advantages and disadvantages of heat pumps in detail, to help you make an informed decision and make a wise investment towards this low-carbon heating technology.
Advantages of heat pumps
Heat pumps can be a fantastic choice for your home in many ways. Listed below are some of the advantages you can get by installing a heat pump.
Heat pumps can be a fantastic choice for your home in many ways. Listed below are some of the advantages you can get by installing a heat pump.
- Cost-effective operation: Heat pumps are more budget-friendly than combustion-based systems, offering potential annual savings of up to £1,400, despite some upfront costs.
- Low maintenance: Heat pumps require minimal maintenance, typically checked annually by the homeowner, and professional inspections are only necessary every 3 to 5 years.
- Enhanced safety: Heat pumps are considered safer than combustion systems as they don’t rely on burning fuel for heat production.
- Reduced carbon footprint: Heat pumps efficiently convert energy into heat, significantly lowering carbon emissions, with some models achieving nearly 600% efficiency.
- Cooling capability: Heat pumps can switch to cooling mode during hot weather, functioning as air conditioning units, especially air-to-air heat pumps.
- Longevity: Heat pumps have a lifespan of approximately 15-20 years, offering reliable, long-term heating solutions.
- Boiler Upgrade Scheme: The UK’s Boiler Upgrade Scheme provides financial incentives of up to £7,500 for air source heat pumps and ground source heat pumps, promoting the adoption of low-carbon heating systems. This makes an air source heat pump installation cost equivalent to getting a new boiler.
Heat pumps are one of the most efficient home heating solutions available. However, there are some drawbacks to weigh in when choosing a heat pump.
Disadvantages of heat pumps
Heat pumps are one of the most efficient home heating solutions available. However, there are some drawbacks to weigh in when choosing a heat pump.
- Costly upfront investment: Heat pumps do bring long-term energy bill savings and reduced carbon emissions but the initial investment varies between £8,000-£45,000 which can be a significant disadvantage.
- Complex installation process: Prepare for detailed planning, involving heat movement considerations, local geology, and your heating/cooling needs.
- Environmental concerns: Heat pumps aren’t entirely carbon-neutral due to electricity usage and some of the used fluids for heat transfer raise environmental concerns. Therefore, it is recommended to use biodegradable fluids or renewable energy sources like solar for true carbon neutrality.
- Significant house and garden disruption: During the installation, the building cladding might need to be penetrated causing potential inconveniences.
- Weather-driven reduced efficiency: Cold weather challenges like icing for air source heat pumps may reduce efficiency and increase electricity consumption, while ground source heat pumps perform better in low temperatures.
- Mandatory planning permissions: Special planning permissions are necessary in Wales and Northern Ireland, with England and Scotland requirements contingent on property size and location.
