Underfloor heating with a heat pump: why it is considered an ideal combination

Underfloor heating operates efficiently with low water temperatures, which is particularly well-suited for heat pumps.

Low flow temperature

The floor has a large surface area, therefore it can deliver the required heat with lower temperature water.

COP improvement

The lower the required flow temperature, the easier the heat pump operates and usually the better the coefficient of performance.

Uniform space temperature

Heat is distributed over a large surface area, creating a more uniform thermal field.

Thermal inertia

Underfloor heating reacts more slowly to setpoint changes, therefore it requires a different control logic than a fan coil.
