Coal stove vs heat pump. The difference in bills is significant, but not necessarily in a positive way.

A family in Poland transitioned from coal heating to a heat pump, significantly reducing energy consumption and costs. Their investment of 75,000 PLN included thermal modernization and the heat pump installation. The new system cut energy needs by half and costs to about 3,000 PLN annually, with a payback period of five years. However, the effectiveness of heat pumps can vary based on several factors, including proper selection, insulation, maintenance, and weather conditions.
