Probably past time to replace our 30 year-old oil boiler and looking for suggestions. We're in the north country and forced hot water has been our primary means of heat. We now also have mini-splits and used them some for heating last winter however they're not enough when it gets really cold, so we still need something else. Getting a gas boiler is probably a non-starter given the extra costs of venting gas. Is there something else other than a replacement boiler we should look at? Or is there a new type of oil boiler that pairs up with PV and PWs?
