You may think that you have a perpetual motion machine. But the s-power vacuum tube collectors work only according to the laws of physics. These laws are exactly applied using precise technology and e.g. they don't only use the direct radiation from the sun but also the diffusely reflected radiation since the back of the absorber is also coated.
With radiation of 1000 1200 kWh* per m2 per year (normal in Germany), the s-power vacuum tube collectors can achieve savings in heating oil of 140 200 litres per year. If we assume that the heating oil price is 1 now and will be 2 per litre in 5 years from now, then the s-power high performance system doesn't just pay off, but it simply is a must! For the sake of your wallet and of course for the environment.
