I have a Buderus Logano G215 boiler heating my 1870s home via a mix of iron radiators and baseboard units. Net IBR output is 149k BTUs

It works well enough, but is running on heating oil and I do not want to go into next heating season paying $6+ per gallon.

the ”easy” button is converting the burner to natural gas, which is available at the street. The utility company and permitting process may take 6months or longer though.

house is roughly 3000 sq ft. with a typical amount of windows, and decent insulation for its age. my climate is reasonably cold in the winter, think Baltimore.

realistically What are my options to replace the boiler with a heat pump that can heat the circulating water for the baseboards and radiator?
