We are in Germany and switched to a heatpump system 4 years ago through incentives over the "Marktanreizprogramm" we got over 45% of the costs reimbursed. It's not even only on the supply chain crisis it's simply ramping up production and training installers because everyone was totally fine with just doing oil and gas for a long time but now everyone scrambles. Shortsightness not only from the state but everyday people and businesses. Thank god for being Links-Grün versifft.
