Why renewable energy and what are the benefits?
We are committed to renewable energy and feel strongly that it will help to protect the environment for future generations. We support other local renewable specialists and have forged some strong alliances in this area. With the world’s ever changing climate and unstable weather, renewable energy is slowly becoming more sought after to heat our homes and provide electricity. Not only can it help the environment by reducing greenhouse gases but it also helps with providing you a saving and an income that is generated through renewable energy. The benefit of renewable energy is that it can virtually never run out due to natural replenishment. Energy from renewable resources—wind, water, the sun, biomass and geothermal energy—is inexhaustible and clean. Renewable energy currently constitutes 15% of the global energy mix. The costs of technologies to capture that energy are rapidly falling and becoming economically competitive with fossil fuels, while reducing the risk of climate change. Investing in renewable energy creates jobs, fosters economic growth, and improves energy security for countries that lack domestic fossil fuel resources. Many of our properties recently completed incorporate some form of renewable energy such as air source or ground source heat pump or solar photovoltaic panels.

AIR SOURCE HEAT PUMPS (ASHP)
Air source heat pumps absorb heat from the outside air. This heat can then be used to heat radiators, under floor heating systems and hot water in your home. An air source heat pump extracts heat from the outside air in the same way that a fridge extracts heat from its inside.

The benefits of Air Source Heat Pumps

  • Will lower your fuel bills.
  • Could provide you with an income through the governments Renewable Heat Incentive (RHI.) From April 2014, ASHP pays 7.3p per kWh.
  • Lowers your carbon emissions compared to fossil fuels.
  • Heats your home and provides hot water.
  • Doesn’t need fuel deliveries.
  • Needs little maintenance – they're called ‘fit and forget’ technology.


GROUND SOURCE HEAT PUMPS (GSHP)
This type of heating pump moves stored solar energy, sometimes referred to as ground source heat, into the home to provide a total solution for domestic hot water and all heating needs. Ground Source Heat Pumps not only make use of renewable energy in the form of ground source heat, they do so in a highly efficient manner.

Collection of this ground source heat is achieved by installing a series of pipes (a ground loop) in the ground which contain a water and glycol (a type of antifreeze) mix at a low temperature. Pipes can be laid in trenches or using boreholes for heat pumps. The surrounding soil is at a higher temperature, typically 10˚C – 13˚C which gently warms the glycol mix as it is pumped around the ground loop. A temperature increase within the ground loop fluid of just 3˚C or 4˚C is all Ground Source Heat Pumps require. The returning warmed liquid is fed into a Heat Exchanger / Evaporator.
 
The benefits of ground source heat pumps  

  • A ground source heat pump (also known as GSHP):
  • Will lower your fuel bills.
  • Could provide you with an income through the government’s Renewable Heat Incentive (RHI.) From April 2014, GSHP pays 18.8p/kWh.
  • Lower your home’s carbon emissions compared to fossil fuels.
  • Doesn't need fuel deliveries.
  • Heats your home and provides hot water.
  • Needs little maintenance – they're called ‘fit and forget’ technology.

Solar PV
Solar PV works by converting solar energy directly to DC power; this is achieved by placing panels (or cells) on to the roof. An inverter will convert this energy to AC electricity. When generating electricity any surplus created can be used or sold back to the grid.

Savings
A 4KW system can generate around 3,500 kilowatt hours of electricity each year – about three quarters of a typical households electricity needs. It will save over a tonne of carbon dioxide every year. The Feed-In Tariff scheme (FITS) typically generates savings and income of around £600 a year (based on a 4kW solar PV system eligible for a generation tariff of £14.90p/kWh – September 2013.)
