As the title states I may be switching over from oil to natural gas sometime before the next heating season. I have been hard at work trying to get our local utility company to bring natural gas to my neighborhood and I have a few questions that I thought maybe some of you could assist me with. The utility company is offering to provide service to the house and I would be responsible for everything inside the house. They are offering substantial rebates on new equipment up to $1000 (I think) depending on the efficiency. They stated that a conversion could cost the homeowner $7000-$8000. They even offer a service that will take care of everything, oil tank removal installation, etc. I do not have to call anyone. They will set up the entire conversion and even process the rebates. My current set up is a Dunkirk Empire II oil fired boiler with a coil for domestic hot water. The unit was installed by previous owner in 2006. It has the Energy Star rating and the efficiency is somewhere in the 85% range +or-. 1) Can I just switch out the oil burner for gas and not replace the entire boiler? This would be a much less expensive option. Looking around on the Internet has given me mixed results, mostly stating that efficiency would drop. 2) I have about 300 gallons or so currently in my oil tank. By the time the next heating season rolls around I should be down to about 250 gallons. That's nearly $1000 worth of oil! Will the oil company buy back the oil? I doubt it. So, the real question is... What do I do with the oil? I hate to see it get pumped out and disposed of. If I had realized this sooner I would have stopped automatic delivery. 3) If I do end up replacing the entire boiler should I go with another tankless system or get a separate hot water heater? We have had problems running out of hot water in the winter with our current system. This is a separate problem to be resolved. We literally run out after 2 minutes in the shower and it takes another 2-3 minutes to get hot again. We do not have a high demand. Just the wife and I and we shower about 30-45 minutes apart. So, I am a bit bias against the coil system. 4) If I did get a separate hot water heater should I go with the gas or a hybrid electric? Electric runs about 16 cents per kwh. 5) Anyone out there with natural gas and still burning wood? Thanks in advance for all your help.
