Use free solar heat for DHW and heating

Our Combination Storage Tank with integrated hot water tank combines both applications in an ideal manner. Various heat generators can be connected to this tank without enormous controlling efforts. 5 or 6 of our Solar panels in combination with our Kombi 1000 are sufficient to cover about 30% of the total annual heat requirement of a well insulated single-family house. An advanced Tank-in-Tank-System effectively preheats the cold water, which is fed in the bottom of the hot water tank, by a "stream channel" and supports the temperature layering in the buffer tank. The tight-fitting 100 mm heat insulation made of high quality flexible foam guarantees minor heat losses and an ideal utilisation of surplus energy. The installed magnesium anode and the double layer enamelling guarantee the tank’s corrosion prevention. The main problem of combination buffer tanks with internal hot water tank is the construction of the interior wall which is not able to withstand counter pressure. If the tank is loaded incorrectly the interior wall might be damaged. This problem is solved clever and easy by our tank system. The internal hot water tank is provided with rolled-in grooves that guarantee a perfectly stable interior wall. Moreover, the exchanger surface is going to be enlarged and an improved hot water performance is achieved.
