Peerless ECT boiler: converting to gas?

michaelendy Member Posts: 2
I recently bought a PA home with a Peerless ECT boiler running on oil and want to switch to gas. 2 contractors have reviewed the system and each has a different approach. Both commented that the boiler is fairly new and has been very well maintained, but one suggests using the Carlin EZ Gas conversion burner, while the other suggests starting over with a new gas Peerless ECT boiler. Any thoughts to help me make this decision? Is there a significant efficiency or life of boiler difference to either option?

    Properly set up, a conversion with an EZ Gas is pretty straight forward, and has been done plenty.
    Properly set up means full cleaning, correct inlet pressure, correct air, proper orifice, change the baro to dual swinging, and probably lining the chimney.
    Plus you can keep the oil burner and switch it back if needed.
    The one who wants you to buy a new boiler probably doesn't know how to do a conversion.
    I personally, if you don't need a new oil tank, would stick with oil. Oil prices are volatile, sure, but can, and probably will come down. Gas will keep going up.

    @michaelendy , are we talking about natural gas (piped in from the street) or LP gas (stored in a tank on your property?

    If the former, it's a no-brainer.

    If LP, I would agree with the other posters here. You really won't save money. And, since LP gas is heavier than air, if a leak occurs it will pool on the floor waiting for an ignition source to make it explode. Natural gas doesn't have this issue.

    Either way, you don't need a new boiler.

    @Steamhead Yes, natural gas. I should have specified. I appreciate the answer!
