Air Source Heat Pumps 

An air source heat pump is a renewable heating system that uses electricity to take warmth from the air outside and uses it to supply you with heat and hot water. The machine absorbs the heat into a fluid, compresses this fluid to increase its temperature, then sends the resulting hot water to your radiators and underfloor heating system.
Although air source heat pumps can meet the heating and hot water needs of an average household, you could combine heat pumps with other technologies to maximise your carbon savings and minimise your energy bills. For example, solar PV could be used to generate the  electricity that powers the heat pump, and if this was coupled with a battery, stored power from the PV panels during the day could heat hot water for baths and showers at night.  

Maintenance costs for air source heat pumps are low. They are reliable, work automatically and most will operate for 20 years or more. Your installer should advise on any maintenance required, such as an annual check by you and a service every few years by a professional.

Heat pumps make most financial sense in properties which are off the gas grid and which therefore use expensive fuels like electricity, oil, LPG or coal for space heating. If you’re connected to mains gas which is cheaper than electricity for each unit supplied, you will need to make sure your home is well insulated, because the heat pump will need to work efficiently to save you money.

Residential Wind Turbines

A mid-ranged domestic turbine of 5 kW can provide around 8,000 kWh to 9,000 kWh of energy per year under the right conditions. Smaller turbines of around 2 kW can have an electricity generation of up to 3,000 kWh.


Larger residential turbines have the potential to reach 15,000 kWh.

Some domestic turbines can reach over 15 kW however these tend to be much larger than those up to 10 kW. As a result, they are more suited to farms and large private estates.


EV Electric Vehicle Charge Points

If you have a 100% electric car (BEV) or a plug-in hybrid (PHEV), charging points allow you to charge your car’s battery.

There are various places you can do this, including:

  • Home (assuming you have off street parking)
  • Work
  • Motorway service stations
  • Petrol stations
  • Certain streets and car parks
  • ‘Destinations’ including hotels, sports centres, shopping centres, supermarkets, etc.

Charging points are also known as charging stations, car chargers, charge points, EV chargers, wall boxes, superchargers – the list goes on and on!
