Solar and Geo Thermal Energy Facts |

Solar Thermal Solar thermal roof panels - http://www.energysavingtrust.org.uk/Generate-your-own-energy/Solar-water-heating Costs for a typical solar water heating system range from £3,000 to £5,000. Savings are moderate - a solar water heating system can provide about a third of your hot water needs, reducing your water heating bill by between £50 and £85 per year. It will also save up to 580kg of CO2 emissions, depending on what fuel you will be replacing. Maintenance costs are very low. Most solar water heating systems come with a 5-10 year warranty and require little maintenance. You should take a look at your panels every year and have them checked more thoroughly by an accredited installer every 3-5 years, or as specified by your installer.
All savings are approximate and are based on the hot water heating requirements of a 3 bed semi detached home with a 3.5m squared panel. The Energy Saving Trust is a non-profit organisation jointly funded by the British Government and the private sector in order to help fight climate change by promoting the sustainable use of energy, energy conservation and to cut carbon dioxide emissions in the United Kingdom. Payback period = 3000 / 85 = 35 years According to 'Which' a typical installation will cost you £5500. You will save around 10% of your heating bill per annum. That might be around £100 per annum.
Payback period = 5500 / 100 = 55 years So is this such a good deal?

Geo Thermal Ground source heat pump - http://www.energysavingtrust.org.uk/Generate-your-own-energy/Ground-source-heat-pumps Costs of installing a typical system range from about £7,000 to £13,000. Running costs for a year, where all hot water and space heating can be provided by the system are likely to be around £650 per year, but will depend on a number of factors - including the size of your home and how well insulated it is. Savings can be considerable - up to 540kg of CO2 and
£160 if you're replacing an oil-fired central heating system.
Savings above assume ground source heat pump installed in a detached property which provides 100% of space heating and up to 50% of domestic hot water, the additional 50% is met through an electric heater. The Energy Saving Trust is a non-profit organisation jointly funded by the British Government and the private sector in order to help fight climate change by promoting the sustainable use of energy, energy conservation and to cut carbon dioxide emissions in the United Kingdom.Payback period = 7000 / 160 = 43 years
