If you want to heat your house with 100% renewable energy, we're offering the Swedish Solar Group's winning concept. When tested at SP (Sweden's Technical Research Institute), this package with solar collectors and accumulator tanks saved 1.8 tonnes of pellets per year (22.4%) compared to only pellet boilers that needed 8 tonnes / year. You get "every five years for free" with our package! Our concept became "best in test".
