“ A total of around 575,000 residential heat pump units were sold across 11 European countries from January to March 2026, up from 494,000 in the same period in 2025”

Not a big increase on a relatively small base. What is the takeaway here?

2.3 million a year for something with a 20-30 year lifetime is a lot. It's not quite enough for "in 20 year everyone will have one", but you only need another 5 or 10 years of similar 15% growth to get there.
