Germany is struggling to get people on-board with a green energy movement that involves banning high footprint domestic heating systems (e.g. gas boilers)-- thus forcing people to migrate to heat pumps. A low-income family who was interviewed said it would cost €45k to install a heat pump in their terraced home in Bremen.
That price tag sounds unreal. I am baffled. What’s going on here? I guess I would assume an old terraced German home would likely have wall radiators that circulate hot water. Is the problem that a heat pump can’t generate enough heat to bring water to ~60°C, which would then force them to add a forced-air ducting infrastructure? Any guesses?

Tiny house = very tiny and probably new and well insulated.
Estonia also likely has very low labour costs and less difficulty finding staff.
Hydronic systems are usually in the >15kW range, and often have split indoor and outdoor units so you need to both do the refrigerant piping between indoor and outdoor, and the water piping to the radiators. Many systems also include domestic hot water heating as part of the same system, so three separate sets of plumbing.
In most of the first world, purging linesets, vacuuming, and releasing refrigerant is usually ~$500.
