In the UK, the average price to install an air source heat pump is between £3,000 and £15,000.
If you are planning to install an air source heat pump in your living space, it is better to know the prices before making an informed decision. Air source pumps are becoming an increasingly popular heating solution in the UK due to their energy efficiency, lower carbon emissions, and long-term benefits.
They are easy to install as they can also work with the existing underfloor heating system or central heating system. However, there are several factors that affect the cost of its installation, such as the property size, system type and installation complexity. This blog will explore everything about the cost of installing air source heat pumps, helping you to understand what to expect and how to plan your investment effectively.
What is an Air Source Heating System?
Air source heating, also called an air-to-water heat pump, works by absorbing heat from outside air and transferring it into your home’s heating system. This heat is then used to warm radiators or underfloor heating and heat water for taps, showers and baths. Even in colder temperatures, these systems can extract heat from the air, making them a reliable and energy-efficient alternative to traditional boilers.
Key Factors Affecting the Cost of Heat Pump Installation
There are several factors that influence the cost of installing a heat pump, such as:
Property Size and Layout
The size of your property is a key factor that can affect the installation cost. If you have a big house, powerful and strong units are used. Properties with complicated layouts may also increase labour costs because installers may need additional pipework, electrical work, or positioning adjustments. Accessibility between the outdoor unit, indoor cylinder, and existing heating infrastructure can also affect the overall installation time.
Type of the Heating System
There are different types of heating systems, such as air source heat pumps, water source heat pumps, and ground source heat pumps. Some of them are more advanced or have hybrid systems. If you need a more advanced system, it costs you more but stays efficient for a long time, such as the air-to-air systems, which are more costly. They are used for the purpose of heating both water and the house.
Complexity of the Task
Installation costs increase when additional work is required. It may require additional work, such as ductwork, structural changes or electrical adjustments. This may include:
- Upgrading existing pipework to handle higher water flow
- Replacing or upgrading radiators
- Improving insulation to reduce heat loss
- Making structural or electrical modifications
Table for Installation Cost
Property Type | Average Price | Capacity or Size |
One to two bedrooms | £1,200 | 4 to 6 kW |
Three to four bedrooms | £2,400 | 4 to 16 kW |
Five to six bedrooms | £3,500 | 8 to 16 kW |
How Much Does Heat Pump Maintenance Cost?
On an annual basis, the average cost for maintaining the heating system is between £150 and £300. Some of the common tasks of maintenance include checking the coils, ducts and filter for any dirt or debris in the heating system. However, complex tasks such as inspecting all the electrical parts and the refrigerant level need professional services, which raises the maintenance price.
Common Tasks
Some of the maintenance or servicing tasks include:
- Looking at the signs of general wear and tear in the heating system.
- Confirming the system is in excellent condition, and the settings are accurate.
- Checking the filter system for better water quality.
- Washing the evaporator for efficiency and maintaining airflow.
Heat Pump Running Cost
Heat pumps are considered 3x more efficient as compared to the gas boilers. Therefore, you have to pay 4x more for each unit of electricity.
Size of the Home | Average Cost | Average Demand (Annually) |
One to Two Beds | £855 | 7,312.5 kWh |
Three to Four Beds | £1,205 | 11,212.5 kWh |
Five to Six Beds | £1,700 | 16,575kWh |
Final Thoughts
It is crucial to understand the total cost of an air source heat pump before investing. Factors such as installation, maintenance, operating expenses, insulation improvements, and property specifications all affect the overall price.
Although installation costs can seem high initially, heat pumps offer excellent long-term efficiency, reduced emissions, and lower environmental impact. With government grants available and energy efficiency becoming increasingly important, many homeowners now see heat pumps as a future-proof heating solution.
