In April 2011 the government will be introducing the Renewable Heat Incentive (RHI). This will pay an annual income to owners of professionally installed solar water heating systems. Making a DIY solar water heating panel is still a fun project for people who love to tinker, but taken over the lifetime of the system it is no longer a money saving option. Therefore we recommend using the two DIY designs in Choosing Solar Water Heating only as creative projects. They are useful for those who want to understand basic construction principles but should not replace a professionally installed system.
