Module heating circuit K35 DN25 4-WM with additional connection

The module heating circuit K35 with Wilo Stratos Pico 25/1-6 features an additional connection for a second flow temperature.
The 4-way mixer is used together with a buffer tank which can be heated through a solar system, solid fuel burner or common boilers. If the user only requires a low temperature level, like with e.g. panel heating systems, the 4-way mixer removes the flow water from the medium buffer area first.
The water is only taken from the top, hot buffer level if the temperature falls below a threshold value. The use of two buffer areas for different flow temperatures makes the system more efficient. The return temperatures are low and the temperature layers in the buffer tank remain the same. The module heating circuit provides the applications at heating systems with buffer tanks and fresh water station and at underfloor and panel heating systems.
