I have a 30 year old Texaco boiler with a summer winter hookup. Whenever
the heater comes on, there's an oilsmell strongest near the basement
steps, over the oiltank- heater is at other end of basement. It's a
fairly small basement though.
We were going to replace the heater, but someone suggested that this is
a repairable problem. Something about not all the burners firing, or
something like that. We have a contract for maintenance/cleanout, but
no one has identified the problem. Is there something particular we
should look for? We have no gas service in the house, so that's too
expensive an option to convert. TIA for any suggestions.
