That's some good advice about using oil as opposed to propane, and then just get the oil boiler or oil furnace cleaned up of the old oil soot residue every one or two years. When the oil service company does a yearly or two-yearly tune-up and cleanout, they spend a lot of time using long skinny scrub brushes and a vacumm to get all the old soot out from around the heat exchanger area in between the inside and outside of the boiler or furnace. Plus, they replace the oil nozzle, which you can purchase for about six dollars at Lowe's-Gilford or just window shop various boiler-furnace heat parts like nozzles, hot water circulator pumps, and thermostats, plus a few other heating parts.

Most local hardware stores do not carry heating parts, and businesses like F W Webb will only sell to a plumber or heat-installer and refuse to be helpfull to someone they do not know, so it can be very helpfull to be able to window shop heating parts at the Lowe's-Gilford.
