Solar Hot Water & Heating

High efficient use of solar heat
Fresh water has a tab temperature of 10–20° C and thus leads to excellent efficiency of solar thermal collectors
Many buildings, like multi-family homes, hotels, hospitals, dorms and prisons have high sanitary hot water demand all year round. For these buildings solar thermals are perfect in combination with a hot water storage. The solar energy is yielded during the day and can be used all day round, e. g. in mornings and evenings, when inhabitants take a shower. Other use for hot water is kitchen and laundry.
