After carefull and in depth research I found the perfect biodiesel furnace . I'm almost sure it's no more then 40 years old . Last year when I got it for free I started using unwashed biodiesel . I spent more time with my furnace then my wife . Then I started using the same washed and dried biodiesel I use in my van's and car . Nice heat but I was cleaning the tip every 5 to 7 days . This year I updated my biodiesel plant by adding a 1 micron sock filter . I had to put a smaller tip in the furnace with the 1 micron filter the biodiesel just flew through the furnace . The biodiesel is so clean I don't even have a filter from my tank to the furnace .
You don't need a fancy pump . They will all work . All you need is very clean biodiesel . After over 5 years and between 70 to 80,000 liters I am learning a few things . This is the first year I could use B100 in my 88 E350 Ford in temps running 0 C. The filter makes the fuel so fine it can't gum up . When I see what the filter looks like after 1,000 liters and think that was trying to get through the tip .
There's a local company pushing imported biodiesel selling it as B20 . I have been talking to a few service guys who say it's gumming up pumps in less then a year . The service guy's were told the pumps are not biodiesel comparable . It's just poor quality biodiesel .
So wash dry and filter your biodiesel and it will work in any furnace the only thing you need to do if you are using your old tank and lines . Put a filter next to your pump
