Air Source Heat Pumps (ASHP):
Using energy from the air, an ASHP converts this energy via heat exchangers that can supply hot water and heating. Producing heat when outside temperatures are as low as -20c. means that an ASHP will operate all year round. The 'efficiency' of an ASHP is measured in its Coefficient of Performance (CoP) which is 3 to 4. This means that for every 1 unit of electricity needed to power the ASHP it will create 3 units of heat energy.

Solar Thermal (water heating):
Solar panels, called collectors, when fitted to your roof use energy generated by the Sun to warm water that is then stored in a hot water cylinder. There are two types of panel, evacuated tubes and flat panels. We can confirm which type will be best suited to your project. The process of Solar water heating works throughout the year but a boiler or immersion heater will be required to top-up the water temperature in winter months.

Solar Photovoltaic (electricity generation):
PV cells fitted to your roof use semi-conducting material to convert the sun's energy into electricity, which can then be used to run household appliances and lighting. In circumstances where more electricity is generated than required this can be sold back to your electricity provider.

Cavity Wall - In many post 1920 homes a cavity exists in the two layers of the outer wall. Cavity wall insulation is one of the most cost effective energy efficiency measures to implement. By creating small holes in the outer wall an insulating material is injected into this cavity which acts as a barrier to heat loss.

Roof Insulation:
Without insulation loft areas can account for 30% of all heat loss from a building. Installing 10 inches of loft insulation will greatly reduce this lack of efficiency.

Smart Energy Management Systems:
A system for measuring, monitoring, and regulating the most efficient use of the day-to-day energy needs in a domestic residence via various means i.e. optimum voltage use on household electrical goods.

There are means of subsidising your project with grants available from various sources i.e. Lottery funds, national and local Government backed schemes. We are able to assist you with both the research and application process of obtaining access to these grants.
