Application • Use
Solar water heating and heating support
Buffering for gas, oil and solid fuel boilers as well as heat
pumps
Hygienic water heating via instantaneous heating
Special advantages
Buffer water heated with solar energy can be used for direct
space heating.
Boiler water and heating water can be charged to the storage
tank without a heat exchanger restricting the performance. This
results in long boiler running time and standstill time with low
emissions.
Particularly low heat loss
Various heating circuits can be connected according to tem-
perature.
Hydraulic separation of heating and boiler supplies.
SOLUS II 560 L low storage tank height for rooms with low ceil-
ings
