Air-Source Heat Pumps in Oxfordshire and the Surrounding Areas | Heat Pump Repairs and Servicing

Much like ground-source heat pumps, air-source devices provide Oxfordshire, Buckinghamshire, Berkshire and Surrey properties with energy through radiators and underfloor heating systems. They are compatible with electric or oil-fuelled boilers, or you can dock them with your current hot water and heating system.


At Steve Cross Heat Pumps, we provide customers with complete solutions which include heat pump installation, heat pump servicing and heat pump repairs. Some of our local service areas include Abingdon, Banbury, the Cotswolds, Oxford and Witney, to name a few.


Air-source heat pumps operate through a controller which balances the operational system to transfer heating and hot water. By monitoring external air temperatures and adjusting output, these pumps compensate for seasonal conditions. They are perfect for Oxfordshire, Buckinghamshire, Berkshire and Surrey properties without sufficient space for ground-source heat pumps, and for new homes with above-average insulation features.

How do Air-Source Heat Pumps Work?


Like ground-source systems, air-source devices use the same principles as a domestic refrigerator – but they extract heat from outside air. Air-source heat pumps use a fan to distribute air across an evaporation heat exchanger. Refrigerant in these pumps boils at temperatures as low as -30˚C, so these systems can pull energy from the air even during the winter months.


System efficiency is vital. For this reason, Steve Cross Heat Pumps provides air-source heat pump servicing and heat pump repairs on a year-round basis.


There are two types of air-source heat pumps:


  • Air-to-water heat pumps circulate heat through to central heating systems
  • Air-to-air heat pumps which circulate warm air using fans

Are Air-Source Heat Pumps Expensive to Run?


Air-source systems require no ground disruption to install. They also don’t need an energy source from the ground or a nearby body of water. This makes installation less costly. While some experts say that air-source heat pumps are not as efficient as ground-source alternatives, they actually outperform them when air temperatures are higher than those 1m below the ground.


Because climates in Oxfordshire, Buckinghamshire, Berkshire and Surrey are lower during the winter, ground-source heat pumps make a more efficient choice in the UK. Even so, air-source heat systems provide a CoP of 3:1 in the winter and 5:1 in the summer. This makes them an excellent choice for other purposes, such as heating swimming pools.


Air-source heat pump servicing and heat pump repairs tend to be more affordable too. We always advise considering these aspects before choosing one type of installation or the other. We remind you that some air-source heat pumps are not optimised for use in the UK, but those in the Mitsubishi Ecodan range are more than up to the job.



Our team fits your air-source heat pump close to the plant room, should your property have one, in a spot with optimal airflow and away from trees or areas with falling debris. Our heat pump installers must adhere to minimum clearances. This reduces the risk of low airflow or the chances of heat pumps recycling cold exhaust air.



You will need a three-phase electrical supply at your Oxfordshire, Buckinghamshire, Berkshire or Surrey property. This supply must run from the proposed location directly to one of our air-source heat pumps after the initial installation.



The air-source heat pumps we install in Abingdon, Banbury, the Cotswolds, Oxford, Witney and the surrounding areas require a base with a soakaway. Our company includes bases and soakaways into your quotation.



Like all installations, air-source heat pumps remain efficient through regular maintenance. Our company specialises in heat pump servicing, and we offer a complete aftersales service which optimises CoP, heating ability and water temperatures.
