From the very beginning we designed a solar water heater – the CALPAK MARK 4 – that best meets the most important requirement: high efficiency and therefore great economy. We thought differently and dared to innovate with the confidence of our many years of experience. We have stubbornly preserved the traditional values of our products for robustness and durability because we know that only then does it make sense to invest in a solar system. We have used cutting edge technology, the best quality materials and the incredible production capabilities of our new factory. But most of all, we used the passion of our people to create a product that makes us truly proud.
