There are a few units out there. And yes, they are very maintenance intensive. Where are you located

    Waste Oil Boilers

    I have a customer who owns a auto shop and he is looking for a waste oil boiler. Does anyone have any experience or knowledge of a manufacture. I know they will be more maintainace, but if has axcess to500 gallons of waste oil a month it may make sense.

    they are starting to get hammered

    on their emissions. It's really hard to get them burning clean with so many "unknowns" in the fuel.

    I think Canada has or is in the process of banning any new installations. Seems more and more of used oils will be re-refined and used over and over.

    Also the synthetics are getting hard to burn and light off. Flash point is engineered so high to extend it's life.

    The Rocky Mountain region has some of the lowest fuel NG costs in the US. Crunch the numbers carefully, and figure low 80% maybe mid 70's for waste oil burning. By the time you permit and install the system with all the safety equipment required...??

    Around here a lot of folks need to sign off on installations, especially storing over 350 gallons. EPA, Watershed groups, Fire Marshall, insurance carriers, local mechanical permit review. Probably others I've forgotten.

    Nobody wants to clean them as required, efficiencies REALLY drop when they ash up :)

    I've taken 10 trips down the waste oil boiler road. wish I'd had stayed home.

    Other than that I think they are great ;0

    Waste oil Burners

    I own a HeatMor dual fuel stove. Wood on one end, with a waste oil burner on the other. We didn't use the waste oil burner for the first 2 years after we moved into our new home. Started it up this Winter and really like it. No more firewood, happy days. The manufacturer of the waste oil unit is Kagi.

    Good luck, Scott

    Inov-8 and Reznor purchase our boiler blocks and with slight modification for their burner offer waste oil boilers. Please contact me at 1-800-283-3787 during the work day and I can provide phone numbers.
