Oilburner:

Seems like you got it running nicely.
I have always preferred forced air ( blown) type setups over draft for the reasons of cleaning and flexibility in the power you can get out of them. Draft is always limited in that you have to have a certain size fore to create enough draft and heat or that you max it out. Not saying it doesn't work, clearly it does but forced air works so much better.

You are averaging roughly about 20 Kwh out of the heater at the fueling rate you are giving it which is the same as a mid size wood stove will produce. The nice part is you can easily quadruple that at start up to get the chill off and then back it way down to sustain the Heat.
Being a heavy set up it will radiate the heat gently and not be too temperamental. I'll bet you are able to shut it down some time before you are finished in your shed and the stored heat keeps the place warm for a good while.

What size tank are you using and do you have to adjust your flow much as the fuel is used?  This is one reason I like a dosing type pump arrangement. The fueling is the same wether the tank is near full or empty. If you are working around it and giving it a tweak every so often insn't a problem, so much the better.

I am wanting to get started on the oil heater for my house but I'm a bit premature.
40O C here today and the 737, DC10 and other jet water bombers were flying over every 10 Min  for the fires burning not 20 KM away. Between the smoke that looked like thunder clouds only far more sinister and the Jets running low level steep turning passes overhead, place looked like the set of a doomsday Movie here today. Saturday is supposed to be worse with temps of 45oC plus.
 In American Terms that's ummm, Forking  damn hot!

With a bit of Luck the smoke won't be as bad tomorrow and I'll be able to see the back fence again.
Not really weather to be constructing oil burning heaters and firing one up would rightly have one shot by the Neighbours long before the police arrived to take me away.

Nice setup and I'm glad it worked out for you and hope the suggestions were of some help.

Rapidrob:
I preheat the stoves burner with about 1/2 cup of old Diesel. This gets the brake drum burner and oil feed very hot with the air off.
Once the oil supply pipe is hot I have a parasitic pump that will give the burner a shot of oil via an adjustable timer. This way the same amount goes into the burner no mater what the oil level is in the supply tank.
I have on order a magnetic high limit switch in case of a run-away-stove. The oil feed and air will be shut off.
I found that a tank holding 5 gallons ( 19 liters) is about right. My tank can be removed from the stove in a matter of seconds for cleaning and the weight of a full tank ( steel paint can) is about what I can lift without spilling.
The tank is 250 m/m from the stove to heat the oil and always allow the oil to flow no matter how cold the oil is initially.
Once the stove is at operating temperature a thin sheet metal shield is placed between the tank and the stove.
The shield catches the air from the automatic  room fan and helps divert it into the shop where I work.
The forced draft blower is a Hot Tub bubble blower. (see photo) It is on a motor control for speed. The one I'm using is actually too powerful, and I could have used the 3/4 HP version. You could enclosed a 4-6" Muffin-Fan and have more than enough air through a steel pipe at the burner.
Sorry to hear about the fire.
I live at 7,000 feet on the side of Thunder Mountain and fires are a real threat . Smokey Bear was from an area 100 miles south of my home. I hope you and yours will be safe.
