Heat pumps which are referred to as Air to Water take renewable energy from the air and provide heating system and hot water in homes. Through the different government grants such as the Boiler Upgrade Scheme (BUS), an Air to Water Heat Pump has never been more cheaper to install. Here in this full guide, you will learn how Air to Water Heat Pump operates, the advantages and disadvantages of Air to Water Heat Pump, the cost relating to Air to Water Heat Pump and grants accessible for Air to Water Heat Pump chiefly concentrating on Air to Water Heat Pump for sustainable and energy efficient UK homes.

What is an Air to Water Heat Pump?

An Air to Water Heat Pump is a renewable energy system, where heat is extracted from the surrounding air outside your home and is transferred and stored in a water tank. This system can offer space heating by radiators or under floor heating, hot water for taps, shower and bath. Air to Water Heat Pumps are different from old-fashioned gas boilers that require the burning of fossil fuels to generate heat; instead, Heat Pumps run on electricity to form a refrigeration cycle.

The pumps used in these systems operate at very low temperatures; therefore, are well suited for use in the UK’s winter climate. Through them they make up to four times the energy that they consume, this helps in slicing the energy bills as well as the carbon footprint.

How Does an Air to Water Heat Pump Work?

The operation of an Air to Water Heat Pump involves several key stages:

  • Heat Absorption: The system’s outside unit pulls heat from the surrounding environment.
  • Compression: The heat is absorbed from a refrigerant is then compressed in order to raise its temperature.
  • Heat Exchange: Some of the hot refrigerant is then channeled through a heat exchanger that directly heats the water in a storage tank.
  • Heat Distribution: It is then used to warm your homes radiators, under floor heating or directly from the taps.
  • Cooling Cycle: After the heat has been taken away from the refrigerant, it is cooled and sent back to the air outside again to repeat the process.

 This cyclic process makes your home ever warm and comfortable as well as providing hot water without wastage of energy.

Advantages of Air to Water Heat Pumps

The popularity of Air to Water Heat Pumps has grown significantly due to the numerous benefits they offer homeowners in the UK:

  • Energy Efficiency: Air to Water Heat Pumps result in high energy savings owing to their COP of up to 4; they generate four times the energy required for their operation.
  • Reduced Carbon Footprint: The pumps are far different from the traditional heating equipment that depend on the burning of the fossil fuels but instead utilize renewable warm air power thus reducing carbon emissions.
  • Cost Savings: Although the first cost of having an Air to Water Heat Pump installed might be expensive, a homeowner can cut energy bills by about £1,000 per year depending on the size of the house and the insulation.
  • Government Grants: These pumps receive support from the UK government with the recent introduction of the Boiler Upgrade Scheme (BUS) where individuals can receive up to £7,500 toward the installation cost of these pumps.

Government Grants and Financial Support

To encourage the adoption of eco-friendly heating solutions, the UK government offers several grants to reduce the cost of installing an Air to Water Heat Pump:

  • Boiler Upgrade Scheme (BUS): Grants of up to £7,500 for homeowners can be claimed to pay for installing an air source heat pump.
  • Energy Company Obligation (ECO4): Intended for the improvement of energy efficiency of property occupied by low-income families, this grant allows completing the installation for up to 100% of the costs.
  • 0% VAT on Clean Energy Solutions: Extended to 2027, this VAT reduction means that household owners do not have to spend so much on installation costs.
  • Warmer Homes Scotland Scheme: Offers financial support of up to £10,000 loan for homeowners in Scotland willing to carry out works in Air to Water Heat Pump. Home Energy Scotland Scheme: Provides self-employment start-up loans max £15,000 for Scottish residents.

Some grants have certain requirements for eligibility and it is important to see which grant one meets the requirements of. By having imposed these financial incentives, the expenses in putting up an Air to Water Heat Pump can really be lessened and become much more plausible for many people to hire.

Air to Water Heat Pump vs Air to Air Heat Pump

Air to Water Heat Pumps and Air to Air Heat Pumpsboil both pull heat from the outdoor air; however, each has a specific utilization. The former is able to supply both heat and hot water but the latter only for heating and not hot water supply. This makes Air to water heat pumps more attractive as the system provides both heating and hot water where needed.

Is an Air to Water Heat Pump Suitable for Your Home?

Also, big houses will require heavy systems which will mean higher costs still, as well as prospects of high savings.


In the case of describing a location to which homes are to be built, it’s important to evaluate if a pump can run efficiently especially when homes are located in cold areas or areas with limited space for installing outdoor units. These pumps are suitable for temperatures that range from -15°C however they have a tendency of performing poorly in freezing conditions.
