Heat pumps, particularly those with inverter-driven compressors, generate high-frequency currents during AC-DC switching. These currents often include DC components and high-frequency residual currents that exceed the capabilities of standard 50 Hz Type B RCDs.

Some installers mistakenly believe that Type B+ devices are suitable for heat pump applications. However, Type B+ is a VDE standard and is not recognised by BS 7671.
