Optimally harnessing the power of the sun:
The perfect stratification of solar heat into the buffer storage tank is made possible by the stratified charging module. This ensures optimal use of solar thermal energy for hot water preparation and heating support. For example in the morning when the sun is weak, the module supplies the lower half of the buffer. Once the sun is sufficiently strong to heat the upper, warmer buffer strata, the system switches to the upper half.
ETA
Stratified charging module
Easy and space-saving installation
The ETA stratified charging module requires very little space and can be mounted either directly on the buffer or on the wall. The installation effort is minimal as all components are already assembled and pre-wired.
Flexible use of solar energy
For individually adjusting the potential use of solar energy. Depending on demand, the switching valve charges the buffer either from the top or the bottom.

Retrofitting possible
The stratified charging module can also be retrofitted. This is particularly advantageous if the existing buffer does not have an integrated solar heat exchanger.
Get some sunshine from above!
A solar heating system is the perfect addition to any biomass boiler. It delivers energy for the hot water supply as well as for heating support even in transition periods and in the summer, thus minimising boiler starts. The following rule applies: the better the buffer layers work, the more free energy you can get
from the sky.
TheStratified charging moduleIt can also be used for smaller solar power systems that require a large buffer storage volume, as well as for very large solar power systems, especially when the solar coil is not efficient enough. The stratified charging module works with two variable-speed high-efficiency pumps and a plate heat exchanger. Depending on the water temperature, it automatically switches back and forth between the upper and the lower buffer halves. If the temperature level of the water from the solar heating system is high, it is fed into the hot strata of the buffer on top. If the temperature level from the solar heating system is lower, it can also be used in that it's simply stored further down – in the colder regions of the buffer. These low temperatures can be used very efficiently, especially in conjunction with an underfloor or wall heating system!
