Sustaining the performance of solar
When it comes to the installation of solar thermal systems, it’s crucial that suppliers, installers and users appreciate the importance of chemical water treatment. Dr. Neil Watson, Global Technical Director at Fernox, explains why this is critical to system longevity, performance and efficiency.
T
he government has committed to a great number of environmental targets, aimed at lowering levels of pollution and the potential effects of climate change. Among them is the target to reduce by 34 percent the UK’s carbon emissions by 2020, in order to be on track to meet the 80% figure in 2050. To achieve these very challenging and admirable targets, the UK Government has also set the objective that 10% of all UK electricity has to be generated from renewable sources.
To switch the required number of people in the UK onto the long term benefits of renewable technologies, schemes have been set up by the government, such as Feed-in-Tariffs (FITs) and the
upcoming Renewable Heat Incentive (RHI), which financially reward homeowners based on their energy output from renewable sources. As a result of increasing legislation and schemes such as these, renewable technologies are fast becoming mainstream. Perhaps one of the most popular systems currently being installed is solar thermal. This is because this technology offers a practical alternative to traditional heating systems in addition to the fact that solar thermal systems is included in the RHI scheme and can help earn points under the Code for Sustainable Homes.
