Savings: Use a solar collector to avoid continuous heating costs. Once the system has been installed, it only needs occasional servicing.
Remember this: A collector involves an initial investment, but after that you save on heating costs and the maintenance of other heating equipment. You may need planning permission to install a solar collector.
Reducing your carbon footprint: A solar collector reduces your carbon footprint by 7% per year. If a million Finns installed one it would save the equivalent of 66,000 carbon footprints. Emissions are lower because less electricity and heat has to be transmitted from power plants.
