Hi guys. I've been looking around this site for a little while now, and getting really interested in making some biofuel for my home heating system. I was able to find guides on how to make biodiesel, but nothing for home heating oil... am I mistaken or is the process the samething?

Welcome to the site!

It's the same thing, but to run pure bio as home heating oil, you need to make some changes to the system. Search around the site for details. I've heard that you can run b20 relatively safely in a home heating system without many modifications.
 

 When making biodiesel for home-heating-oil, you don't need to post-polish the fuel.  Oil fired heaters don't care if the fuel is perfect or not.

 To make home heating oil (raw biodiesel), you only need to build a reactor.

 If you can weld, I would recommend my own plans at www.MurphysMachines.com

If you can't weld, I would recommend an appleseed.

Utahbiodieselsupply.com and b100supply.com are very reputable dealers of appleseed equipment and plans.

Hope this helps

I started making bio for home heat last August. I was a bit scared of putting the fuel in my tank but after talking to a few people and reading on different forums I decided to go for it. I live in northern central CT in a 200 year old house. Yes it IS drafty. Needless to say I require a lot of fuel to keep the house warm. After canvasing local home heating oil suppliers the choice was simple. To date I have made about 600 gallons. I had a little trouble with my furnace at first but was able to resolve them by reading up on my system, going to a local boiler supply house and getting a manual, and experimenting. I had some misfires early on but after cleaning the system, changing the nozzle to a wider angle and smaller volume, and increasing the pressure and adjusting the air flow I have reduced the misfires. I also had to change the tank and pump filters. To date I have not exceeded the cost of having the fuel company come to my house to clean the system and to my delight the system works great.

The key to good bio is getting a consistent supply of good waste oil. My first experiment last year using oil from a local restaurant was very poor. Apparently there was too much fatty acid inthe stuff and all I created was goo. I fianlly found a good source, they are happy that I take take the used oil as they no longer have to pay to get it hauled off. Keep researching and try small batches at first.
