B100 BioDiesel heating oil.

Silvion

Has anyone used this type of home heating oil? Do you need to adjust boiler for this type of fuel?

thanks

I am a huge fan of biodiesel, but you really do need to know what you are dealing with before you make the leap.

B100 is not compatible with most rubber (gaskets, O-rings, hoses etc.) It basically turns them to goo. If you are going to run B100, you need to replace pretty much everything it touches (including inside your pump) with a fluoropolymer (Viton/FKM) equivalent. It has stronger solvent properties than dino juice, so it will put decades-old sludge from tanks, lines, etc. into solution -- which then ends up in your filters. It also holds MUCH more water, which can cause accelerated rusting of uncoated steel tanks.

B20 or less is generally safe to run in pretty much anything. The added lubricity of biodiesel (even B5) tends to act like a fuel conditioner -- really quiets down the injector noise on engines.

Here is a chart I just found on the internet about which materials are affected by different types of bio-fuel. Does anyone know who stocks the Viton oil tank intake tubes? http://biodiesel.org/docs/ffs-performace_usage/materials-compatibility.pdf

This is a link which lists plastic and rubber tubing that work well with bio-diesel. I'd wonder what heating supply distributors or oil techs recommend. http://www.mcmaster.com/#standard-plastic-and-rubber-tubing/=yu4665 (You have to select 'Biodiesel' in the left hand column to narrow it down to that particular tubing.)
