> Are people just not aware that heat pumps are a great solution

In my European country, people struggle to buy houses, nobody is rushing to do a full house renovation.

Furthermore, the consensus is: heat pumps are great for a new home or a full renovation. Installing a heat pump with old-style radiators makes no sense, because the heat pump heats to a low temperature.

That's mostly outdated info, modern heat pumps can heat to high temps. They are more efficient if run at lower temps but so are condensing gas boilers, which are the most directly competing technology.

You can keep the radiators in place when using mini-split heat pumps..
