Hello Adam.  Welcome to the forum!  Yes, a little heat to stay warm helps keep you motivated on projects in the shed.  Thats the part I enjoy most is that I have a nice warm place to work in the winter and dont feel guilty for turning the temp up so it's warm enough to shed the jacket.  Enjoy the forum.  We look forward to hear how your project is going!

Greetings Eug!

Hard to be thinking about burning oil any more here in the US, but I hear it might be a little cooler where you are  .

I cant say that I have ever had, or know anyone who has experience with the chineese heaters.  Many of us out here on the forum have modified some sort of home heating oil furnace or boiler to burn waste oil.  I understand where you are coming from with the hot water heater, but since those arent designed to heat an entire house, I dont know how well they would hold up or if they would provide the amount of heat you are looking for.  I might suggest looking for a used fuel oil boiler if you can find one.  They can easily be modified to burn waste oil and you can use some of the controls to automate your system to turn on and off depending on water temperature.  Now of course this is a big project in itself and you might not want to go down that road and in that case you would want to look more into something like the chineese made one for more of a plug n play option.

Good luck with your project and if you have questions, let us know.  Things are going to be a bit slow around here with it warming up in the northern hemisphere, but there may still be some lurkers out here.  Cheers!

I should also mention that the oring is a size 007.  I found them at Ace Hardware & Oreilly Auto Parts.  They seem pretty common.

ShopSpecialties might be on to something.  I had to replace the o-ring in my ckburner just a couple of weeks ago because it was sucking air.

I have a new Honeywell R7284U1004 sitting on the shelf waiting to be installed.  I wonder if it can cut the spark when it sees flame and turn it back on if something fails?

I have seen several creative ideas like this that can help preheat the oil.  It's these type of creative ideas that can lead to success.  Give it a try and let us know how it works!

I would have to think it is either a spark or fuel problem.  I have in the past disconnected the air supply and watched the spark because my electrodes were grounding out to the retention head.  That would give you an idea if it is a spark problem.

Have you cleaned the nozzle lately?

Ahh ok.  Still the closest one I have met on the forum.  How did you find the site?
