Whether these queries regard our new installations, heat pump repairs or heat pump servicing, our personnel are always happy to pass on their expertise.


For your convenience, we have answered some of the most frequently asked questions below.


Are you looking to create a greener household? Do you want to lower your dependence on unrenewable energy sources? Heat pumps for the home tick every box for the environmentally conscious property owner. With heat derived from naturally occurring sources, i.e. the air and the ground, there’s no need to rely on gas.


This switch to a more sustainable approach doesn’t only deliver environmental benefits. The outstanding energy efficiency of air-source and ground-source heat pump systems means your heating and hot water costs will go down. Needless to say, this will help you to save a significant amount of money over the long term.

  • Certified Worcester Bosch Installer

Are air-source heat pumps cost-effective?


Yes, they are. Firstly, air-source heat pumps don’t require any digging during the installation process. We usually place them at the side or rear of an Aylesbury property. While these heat pumps may have a greater variation in performance than ground-source heat pumps, they still remain a cost-effective source of heat.


To gauge their effectiveness, you must take the air temperature into account. In the winter, air-source heat pumps provide CoP figures of around 3:1. In the summer that increases to 5:1. For comparison, ground-source devices have a steady 4:1 CoP.


In addition, air-source heat pump repairs (and heat pump servicing) are also cheaper than ground-source systems.


Do ground-source heat pumps improve energy efficiency?


Yes, they do. Ground-source heat pumps provide a greater level of energy efficiency than the more conventional heating methods used in Aylesbury and across the UK. For every KW/h of energy required to fuel the pump, it generates as much as 4 KW/h. In short, that’s the equivalent of paying for 1 KW/h of energy and receiving an additional 3 for free.


What does the installation of ground-source heat pumps consist of?


A standard installation typically includes:


  • Ground-source Heat Pump
  • Ground Collector Array
  • Manifold
  • Manifold Pit
  • Circulation Pumps
  • Buffer Tank
  • Hot Water Cylinders
  • Expansion Vessel
  • Manual and Automatic Valves
  • Weather-compensated Control Systems

Due to the placement of ground-source heat pumps, we will need to carry out some digging with machinery.

Do you provide heat pump servicing and repairs?


Yes, we do. Our company prides itself on the service we provide for all ground-source and air-source heat pumps. This extends to the relationships we create with property owners across Aylesbury.


In the unlikely event of any problems with your installation, we provide a swift response for both heat pump servicing and heat pump repairs.

Are you ready to make the switch to one of our heat pump systems? You can rest assured, the installation process is quick and hassle-free when left to our time-served team. Of course, each installation differs from one job to the next. Generally speaking, however, you can expect us to complete everything within 3 days.


This is especially true for ground-source devices, particularly if you need a large borehole. However, not all heat pumps for the home require such work. For example, ductless systems may only take one day to complete.


Everything depends on your preferred system as well as the size and type of property you own. A member of our team will happily clarify your situation during an initial consultation.
