We are not mechanical or HVAC engineers. This concept was developed from our own practical experience and with the help of specialists, with the aim of creating a flexible arrangement for dual-source operation. Individual systems may of course require a different solution depending on their specific requirements and constraints. In all cases, we recommend involving a suitably qualified professional in the design.
The attached schematic is based on one of the most common configurations: a mixed system using both underfloor heating and radiators. The concept therefore assumes a supply water temperature of approximately 50 °C, with the required temperatures for the individual circuits regulated by three-way mixing valves.

A simpler system can also be built instead of this highly flexible arrangement, depending on the required functions and the compromises that are acceptable. Examples of simpler implementations are also shown in our working system examples.
