A standard furnace works by kicking on when heat drops below the set point

So does a heat pump, and you can get Air to Water heat pumps that work almost exactly as a furnace.

The most efficient heat pumps are constantly trickling a little heat at a time, rather than cycling on and off.

Our stoker wood pellet furnace does the same if possible, it can't go below 25% capacity, because it doesn't burn right at lower capacities. So at certain temperatures, it maintains a steady state, but at others it has to turn on and off. A heat pump can easily do whatever is more efficient.

PS:

Heat pumps are similar technology to fridges, which also turn on and off depending on needs.
