Flow temperature is one of the most important parameters for the efficiency of a heat pump.
Lower temperature
Usually improves the heat pump's energy efficiency, but the terminals must be able to cover the heating load.
Underfloor heating
It operates effectively with a relatively low water temperature due to its large emission surface.
Fan coils
Their performance depends on water temperature, flow rate, and fan speed. The lower the temperature during heating, the larger the fan coil that may be required.
Goal
We do not aim for the lowest possible temperature regardless of needs. We choose the lowest temperature that reliably covers the load.
