Combining Technologies
It is common to combine more than one technology in a home to maximise potential. For example Solar Thermal in combination with Heat Pump technology will mean that, during the summer, Solar Thermal will provide domestic hot water rather than relying on the Heat Pump. In a similar vein, a Solar PV system will significantly reduce electricity costs when combined with a Heat Pump. A Heat Pump, on its own, can provide both domestic hot water and central heating needs and depending on your current fossil fuel heating source will significantly reduce your energy bills. In addition it is also a regular occurrence to use Heat Pump technology as a primary heating source whilst using a current system (such as an oil or LPG boiler) as a secondary / back-up system. This is especially relevant for properties who do not have access to the main gas network. Systems such as this are known as 'bivalent' systems and is a viable option for older properties where internal or external insulation is not practical.
Costs:
The costs of installing renewable energy technologies vary depending on the technology itself, 'site-specific' factors and whether any funding is available to help. Our advisor will explain the factors that determine costs but as a guideline go to the Energy Saving Trust website at www.est.org.uk for further information.
Savings:
The savings you can make from installing renewable energy in your home depend on a number of factors. For example a family of 4 who install Solar Thermal to provide domestic hot water will save more than a single occupant. The fuel source you are displacing also has a significant impact on financial and carbon savings especially if your home is heated by oil, LPG or electricity. The electricity you may save by installing Solar PV depends on the size of system, how much the system generates and how you use electricity. We will provide you with estimated savings in line with the Government's standard assessment procedure for energy rating of buildings. Any savings are given as guidance and should not be considered as a guarantee of performance. The Feed In Tariffs and proposed Renewable Heat Incentive will both provide financial savings.
