Are DualSun SPRING panels compatible with OERTLI thermodynamic water heaters?

Yes, DualSun SPRING hybrid panels can be paired with OERTLI thermodynamic water heaters (only OTWH 300EH & OCETD 300EH models). The OCETD 300EH model is better suited to be paired with the PVT panels because of the temperature sensor which is placed better at the bottom of the tank compared to the OTWH 300EH model.

However, the coupling between solar and thermodynamic water heaters is not possible because the water heaters do not include an external contact through which the solar system can control the operation of the heat pump in order to optimize the solar energy input in case of sunshine.
