Ground-Source Heat Pump Installers


Steve Cross Heat Pumps covers Oxfordshire, the Cotswolds, Buckinghamshire, Berkshire and Surrey as ground-source heat pump installers. Our preferred products come from the Mitsubishi Ecodan range. These pumps take heat from the ground before elevating the temperature and transferring the energy to heat properties, or to supply hot water.


Ground-source heat pumps have an operational cycle which works in much the same way as a domestic refrigerator, the only difference being that the cycle reverses. However, ground-source heat pumps can deliver spatial cooling on demand too.


The biggest benefit of Mitsubishi Ecodan ground-source heat pumps is their efficiency. Every KW/h of energy used to power the pump converts to around 4KW/h of energy for use in your property, be it in Oxfordshire, the Cotswolds, Buckinghamshire, Berkshire or Surrey.


From Oxford to Witney, and from Abingdon to Banbury, our ground-source heat pump installers also perform heat pump servicing and heat pump repairs on any installation completed by our company.

Air-Source Heat Pumps


Whereas ground-source heat pumps draw their energy from the ground, air-source heat pumps source theirs from the surrounding air. Designed to work perfectly with radiators and underfloor heating installations, air-source heat pumps are compatible with most electric and oil-fired boilers. Installation requires no ground disruption whatsoever.


You can expect 3KW/h of energy for every KW/h drawn from the air during the winter. This rises to 5KW/h of energy for every KW/h in the summer. Steve Cross Heat Pumps also assists with air-source heat pump servicing and heat pump repairs, whether you’re in Oxford, Abingdon, Banbury or Witney, or any other location in Oxfordshire, the Cotswolds, Buckinghamshire, Berkshire or Surrey.


Our team can even help with your design, supply and commissioning requirements. Any surplus energy created through ground-source heat pumps or air-source heat pumps could entitle you to rewards under the current Renewable Heat Incentive scheme.


  • Our team takes pride in its workmanship and works conscientiously
  • Projects completed within building code parameters
  • Work personally supervised by the business owner
  • Knowledgeable and responsive office management team
  • Complete turnkey capabilities from a single contractor
  • Premium heat pumps from the Mitsubishi Ecodan range of products
  • All our air- and ground-source heat pump installers are CRB-checked

Heat pumps for the home deliver an array of benefits. Not only do they have outstanding energy efficiency and lower running costs, these heat pump systems require minimal maintenance. You can perform simple checks on parts once a year, while professional inspections only need to take place every 3 to 5 years.


Further benefits include safer operation than combustion-based heating systems, lower carbon emissions and devices with a long lifespan. It’s easy to see why an increasing number of property owners are making the switch to heat pumps.

Heat Pump Servicing, Maintenance and Repairs


Steve Cross Plumbing & Heating Ltd covers all your air-source and ground-source heat pump servicing, maintenance and repair needs.


Air-source and ground-source heat pumps typically last between 20 to 30 years. However, to maximise your device’s longevity, and to get the best possible return on your investment, you must schedule servicing and maintenance checks at the recommended intervals. You should check your system at least once a year. For the ultimate peace of mind, you can leave this to us.


As well as these annual checks, current industry guidelines advise professional servicing every 2 to 3 years. With our meticulous attention to detail, we ensure your device continues to perform at optimal efficiency.


We can also identify small issues before they develop into bigger problems. Fast, effective repairs help to keep lifecycle costs down while minimising the chances of a breakdown.

Gas and Oil Boiler Repairs and Central Heating


In addition to our expertise in air- and ground-source heat pump services, our company also covers all installation, servicing, maintenance and repair needs for gas and oil boilers and central heating systems.


We are Worcester Bosch-accredited installers, but we also fit boilers from various market-leading manufacturers to suit your household’s needs.


For your peace of mind, we hold Gas Safe registration (8189).
