Is the video on your YouTube? Haven’t seen it. I’m just starting to look into them myself for a truckmount modification I want to do. Don’t spend too much time on it. Just a ballpark like $1500 or 1750 or 2000 or 2250 or 2500 or 2750 or so on.
Any 12 volt burner is going to need a beefed up charging system to make the heater run at optimal performance. There are different ways of going about this but I found out the easiest for me was to belt drive a 80 amp car alternator to get my heater to run at optimal performance and as clean as possible using diesel. Not had a problem since alternator was installed.
Propane heater will always be the simplest and easiest for anyone who wants to install a fuel fired heater but as for me I will be using diesel from here on out.
More BTU's for every gallon of diesel bought. I use around 4 to 6 gallons of diesel to every $800.00 to $1000.00 made. This is with temp dial set at 200 to 210 degrees. If I turn the temp up it will use more diesel. I use my heater as a tool/weapon. If it needs more heat to get it clean the temp dial gets turned up but most of the time temp dial is set at 200 to 210 and delivers a never ending 190 to 200 to my newer Bentley 10 flow wand. I have not tested it but I do truly believe my heater set at 250 degrees will deliver a constant 240 degrees with a 20 flow wand with trigger on wand tied opened so it sprays constant without let up. My heater is rated at 5 gpm so I don't think it will have a problem with holding heat at 240 with 20 flow, flowing wide open at 600 psi
I agree with the 12volt issue.....I've had alot of problems in the past with 12 volt burners.....switched to 110 with a pressure switch instead of a flow switch ran off an inverter and have never had a problem since not one.
