Do you know this to actually be true, or is this a guess?

Both GSHP and ASHP are classified as low temperature heating. They are more efficient than oil, gas or electrical resistance, but their duty cycle (the ratio of on-time to off-time) is higher than heating with fossil fuels.

My ASHP runs pretty much all the time, but it is extraordinarily efficient.
