Biomass … Solar Electricity … Heat Pumps
Some of the terms used when talking about energy saving and renewable energy can seem quite baffling. The Rykneld Energy Savers are here to cut the jargon…
Biomass Boilers - These boilers run on wood pellets that have been sustainably harvested from forests or coppices and are immediately replanted. This means that when you burn the crop in the boiler, the same amount of carbon is being reabsorbed by the new crop of fuel – it is therefore classed as entirely carbon neutral.
Carbon Neutral - Balancing of the carbon dioxide (CO2) released into the atmosphere from burning fossil fuels, with renewable energy that creates a similar amount of useful energy, so that the carbon emissions are compensated.
Carbon Dioxide (CO2) - produced by human activities, primarily through the combustion of fossil fuels. It is thought to contribute to Global warming and can be reduced through the use of renewable technologies.
Coefficient of Performance (CoP) - The measure of how many units of heat are generated per unit of electricity used to run the heat pump.
Energy Performance Certificate (EPC) – It rates your home for energy efficiency on a scale of A to G. It also provides information on how to improve the energy efficiency and the level you would attain if you put the measures in place.
Heat Pumps - This is a system that uses refrigeration technology to pull solar heat energy out of either the air or ground. The heat pump uses electricity but can be up to around 400% efficient.
kWh – kilowatt hour is a unit used to measure energy. Electricity bills are charged in kilowatt hours.
Low carbon energy– Refers to technologies minimising the amount of carbon (or greenhouse gas) emitted into the atmosphere. At a domestic level it includes air and ground source heat pumps and combined heat and power.
Micro Combine Heat and Power (CHP) – This also produces electricity when running the central heating system as normal. Although they run off mains gas, they are referred to as 'low carbon' technologies as they are up to 90% more efficient than conventional old boilers thanks to producing off grid technology.
National Grid - The National Grid is the high-voltage electric power transmission network in the UK.
Renewable energy – Is energy generated from sustainable natural resources, such as sun, wind, water and geothermal heat.
Solar Electricity (PV) – This is the most common form of renewable energy in the UK, thanks to the Government Feed in Tariff scheme.
