Kero or Oil

What is the collective wisdom on when kerosene is needed? Customer's tank is in unheated porch with 1/2" soft copper line to filter which is located in crawlspace where scorched air furnace is.

This setup looks like it would be ok for oil, but I am a commercial guy. This was just a favor for a friend. The porch is completely enclosed, what temperature would be safe for this setup? I was thinking above zero maybe.

Thanks for the collective wisdom!

    Two pipe with additive when it gets to -10C or below. Never a problem when you move 2.5 gpm through the lines (3/8")

    personally hate two pipe. In extreme cold it causes moisture in the tank which leads to freezeup.
    Add a bottle of Hot to each fill up and top feed from the tank. Add a tigerloop in side to warm the oil for the burner...

    I'll go with that one. Some oil companies -- the one I deal with for example -- put anti-gel (like Hot) in all the oil they deliver in the colder weather -- mostly because at least some of it is used in diesel off-road equipment (yes it's legal) as well as home heating, and there you have to have it (ever try to start a big tractor in the cold when you didn't have anti-gel? Frustrating...).

    I suspect the oil/tank to get to zero degreesF. I was thinking of advising them to build an insulated enclosure around the tank and get some heat from the house to the tank, as the tank shares a wall with the poorly insulated house.

    That wouldn't hurt either... :)

    2.5 GPM? A Suntec does under 20GPH on 2 pipe or .33 GPM

    You could build an insulated enclosure around the tank and then plug a 100w incandescent light bulb under the tank. That would warm up the oil a bit.

    They also make oil line heaters for the pickup, and nozzle line heaters for the burner.
    I think a 25% kero blend gets you down to -25. I used to have a chart when I used to blend.
    I'd bag the 2 pipe, maybe go with a tiger loop inside, but definitely an enclosure and/or heat tape w/thermostat on the fuel line.
