This is a most excellent place for technology news and articles.
So does a heat pump, and you can get Air to Water heat pumps that work almost exactly as a furnace.
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.
