Oil steam boiler vs Natural gas steam boiler

I am confronted with the replacement of two boilers in my two family house. currently I have one ancient boiler and one 40 year old boiler. both are oil fired and provide steam heat, both are single pipe systems.

It seems that converting to FHW would be too costly.

If I stay with Steam heat, does it make sense to convert to Natural gas or stay with oil?

Re: Oil steam boiler vs Natural gas steam boiler

I don't know if this is the answer that your looking for but, since you have Oil heat and are thinking of switching to gas is anything else in your house gas or electric? Like stove, water heater, clothes dryer, if all this is electric it may make sense to switch not just your heat to gas but whatever is electric also. Then again the way gas and oil prices go up electric may be cheaper in the future. I don't really know what your looking for. I have forced hot air by oil and everything else is electric and was thinking of switching all to gas, that was a couple years ago but have yet to do the change. Contact your local Gas Co. and see what kind of deal they will give you if you switch over, I've heard of people getting new furnaces installed free just for switching over, I wouldn't know about Boilers though. Good Luck!!! :)

Have you gotten any quotes for a FHW conversion????

I would strongly recommend a FHW conversion to gas-fired boilers for much higher efficiency & cleaner burning equipment---conversion of the convector distribution system (baseboard) is much easier to do these days--- they pull out all the radiators & put in baseboard, running flexible plastic PEX tubing up thru the walls to connect the radiators to the boilers.

Get at least 6 estimates (Yellow Pages: "Heating Contractors")---fuel oil dealers are also licensed to install gas-fired boilers.

Even if it costs $8k to $10k you will save big bucks in the long run because at least 1/2 your fuel dollars are going right up the chimney with the obselete boilers you have now.

Don't ignore insulation needs: the exterior walls need at least R19 (can be blown in for a few hundred $$$) & the attic needs R40---also blown in---insulation is done BEFORE you order the new boilers & will save big $$$ in fuel costs.

You'll love FHW---very economical, even heat, no noise or daily/weekly maintenance, as you have with steam.
