It might look impressive if you think that 100% is the maximum, but heat pumps can be 300% to 500% efficient.
District heating can also be an inexpensive option if you can negotiate the installation and connection costs, and if you don’t require much heat.
I have personally installed (or rather my grandfather back then) air-water heat pumps in all my homes since the 1980s. When I replaced them in the early 2000s, my electricity bill was almost halved, which was great, especially since the heat pumps and electricity were half the price back then compared to today!
