Yea, I have kind of had mine on the back burner too since I got the pump fixed. I probably wont do a loop system, just take it straight out of the bucket. The garage is heated with electric and stays at least 40 degrees. If the pump seems to be working too hard, I might try to warm it up a bit before it gets to the pump, will have to see how it goes. I rigged up my 5 gallon bucket and have been running it on #1 diesel just to make sure it is going to keep working. I still have to get my controller and cartridge heater ordered, then I will see if I can get the block built. I will take some pics of the furnace in my garage and hopefully post them tonight. Man, that furnace throws off some heat. Cant wait to start burning free fuel!
Oh yea, Kyles system looks pretty good, glad he got you motivated again!
