I think most of those retrofits aren’t cheap because the pipes and radiators aren’t big enough for the colder water. So it ends up needing a whole now install anyway.
It’s probably always cheaper. The government is pushing for air to water. There are no subsidies for air to air which I think is a better way to heat a home.

I can see how that could happen for some homes. Worth doing the calculation though, since it can be cheaper if the pipes are adequate.
