an Air Source Heat Pump?
A heat pump with an air source (ASHP) is an incredibly efficient boiler system that harnesses heat from the external atmosphere, even on freezing days. That heat is employed to warm your home and domestic water.
Many people regard air source heat pumps as a greener alternative to conventional gas or oil boilers, due to the vast savings in carbon footprint that these systems create while providing consistent, reliable warmth.
Due to UK government grants and schemes, qualifying households can potentially have a free air source heat pump installed and benefit from cleaner, cheaper heating. These government grants aim to make the transition to renewable energy more attractive by making the environmental benefits and energy cost savings available to homeowners.

How an Air Source Heat Pump Works?
- Heat is picked up from ambient air with a unique refrigerant fluid, regardless of the outside temperature.
- The refrigerant moves through a compressor, which warms it.
- The hot fluid enters a heat exchanger.
- The heat is transferred to your home heating system (radiators, underfloor heating, or air units).
- The refrigerant gets chilled, and the cycle repeats continuously.
- The system is very energy-efficient, generating as much as 4 units of heat for every unit of electricity it consumes – a renewable and affordable means to warm your house.

Types of Air Source Heat Pumps

Air-to-Air Heat Pump
Best Suited For
Houses with no central heating or space heaters.
How It Operates
Air is warmed and circulated throughout the house, warming it without any water pipes or radiators.
Advantages
Easy to install, efficient during warm weather, and low maintenance.
Drawback
It does not deliver hot water and delivers heat only to the portion of the house where the unit is installed (not to the entire house)

Air to Water Heat Pump
Best Suited For
Central-heating homes already equipped with a water-based heating system (radiators, underfloor heating).
How It Operates
Pulls heat from outdoor air and converts it into a water-based system to warm your house and produce hot water.
Advantages
Complete home heating and hot water integrated with your existing central heating system.
Drawback
Ever so installation costs are slightly higher, and more space for the water storage tank is potentially required..

Air Source Heat Pump vs. Traditional Heating Systems
Is Your Home Suitable for a Heat Pump?

Air source heat pumps are appropriate for the majority of UK homes,
but the following can enhance performance
Effective insulation
Walls, lofts, and windows must be
properly insulated.
Outdoor space
Sufficient space to accommodate the external unit with airflow
Low-temperature heating system
Larger radiators or underfloor heating assist in optimizing efficiency.
Valid EPC certificate
Particularly relevant for grant eligibility.
What Does Air Heat Pump Installation Involve?
Initial Inspection
A trained engineer inspects your premises.
Design & Sizing
A system is chosen according to your heating requirements.
Installation
Usually 2–5 working days, including installation of outdoor unit, hot water cylinder, and system link-up.
Commissioning & Handover
Installer checks the system and demonstrates how to operate it economically.
FAQs
Can I obtain a grant for air source heating?
Yes, through the Boiler Upgrade Scheme and ECO4, a lot of UK homeowners can access
funding for air-source heat pumps.
What is the difference between air-to-water and air-to-air heat pumps?
● Air-to-water heat pumps are designed to be used with water-based systems such as radiators and underfloor heating to deliver hot water.
● Air-to-air heat pumps warm the air within your home but do not supply hot water.
How do I know which heat pump is suitable for me?
If you already have central heating and radiators or underfloor heating, an air-to-water heat pump is your ideal option. If you don’t have any existing heating or require heating for particular rooms, an air-to-air heat pump can be suitable.
Is the installation disruptive?
Most of the installations are completed in 2–5 days and are carried out by qualified engineers. The outside unit will be wall-mounted or garden-installed, and the internal system will be connected to your current setup.
What about if I'm on benefits or a low income?
If you’re on government benefits or low income, you might be eligible for further assistance under the ECO4 scheme. We’ll discuss this with you when you apply.
