Ground Air Source Heat Pump Company Installer  Rugby Warwickshire

Grant Heating is a rapidly growing company specialising in the sustainable and forward thinking technology of Heat Pump Systems, which can be applied utilising the ground, air or water as the source of heat. 

Heat pumps are the most efficient heating and cooling technology available for buildings, and complete efficiency is achieved by our supplying the associated heat emitter systems, e.g. radiators and underfloor. 

We are increasingly taking on installation of MVHR (Mechanical Ventilation and Heat Recovery) projects as buildings become more airtight and better insulated. Additionally we are involved in Solar PV, Rainwater Harvesting and Air Conditioning work.

We pride ourselves in fantastic Customer Service at Grant Heating, and our clients recommend our services to friends family and colleagues.

We work with leading manufacturers to source high quality equipment.

We are responsible for all elements of the systems : from commissioning and design through to installation and servicing of the systems by our own team of skilled team of engineers, and follow up system support.


  •  All of our engineers are fully trained & qualified

  • Only equipment installed from the market leaders

  • Residential and commercial installations 

Benefits of Heat Pumps

  • The optimum system for heating your property, whilst reducing Carbon emissions. 

  • Cutting down on heating costs and fuel bills, especially when heat pumps are replacing conventional electric heating, oil or LPG. Extra benefit in bill reduction when using solar panels for electricity generation.

  • Heat pumps are an ideal heat source for heating your water, indoor space as well as underfloor heating.

  • Heat pumps can function efficiently at outdoor air temperatures as low as -10 degrees centigrade

  • Financial support can be provided through the government-backed Renewable Heat Incentive (RHI).

Benefits of Air Source Heat Pumps

  • Perfect systems for new build projects.

  • In existing properties Air Source Heat Pumps are easier and more cost effective to install compared to a Ground Source Heat Pump.

  • Modern Air Source Heat Pumps are quiet, and can provide cooling as well as heating.

  • More sustainable, efficient and ‘greener’ due to the new generation of refrigerant gases.

  • Minimal maintenance necessary- just an annual service

  • With correct design and installation the expected lifetime is 12-15 years.

Benefits of Ground Source Heat Pumps

  • deal systems for both new build projects and existing properties.

  • Use available garden space or open land with horizontal or vertical ground collectors.

  • Regardless of outdoor temperature, they provide consistently high levels of efficiency. 

  • Unobtrusive and silent- running.

  • No requirement needed for planning permission generally.

  • With correct design and installation, and with regular servicing, the expected lifetime is 20-25 years.

  • Ground Source Heat Pumps extract thermal energy from the ground to provide 100% of your property’s hot water and heating.
