The parts required to build your own heater unit is:
1 x Gas Cylinder either yours or ours, A 45kg for large areas or a old steel forklift 19 kg cylinder for heating a home.With a 150mm flue housing exiting either the top or the back.
The cylinder will require a door made near the bottom of the cylinder for removal or the pot for cleaning.

Building Your Own Heater.
This is how you build your own Fan Forced waste oil heater.
Start with an old unused gas cylinder, if you intend to heat a large area use a 45 kg gas cylinder. A 45kg cylinder for a house would be too big, look into an old steel forklift cylinder 18kg instead these are ideal fo homes spa etc. I built a 45 kg heater for our home some years back, and in the middle of winter our daughter would have her bedroom door wide open to outside, because it was too hot in the house.
OK one cylinder, open the valve up and let all the remaining gas out.
Open the valve and full with water until it flows out the valve. Empty it.
Cut the handle off the cylinder and keep for later.
The Cylinder handle been removed. Clean up any rough edges and put aside.
Grind off any welds that are left over from the handle. Find centre on the top of the cylinder and mark. Cut out a square 100mm x 100mm or 4"x4" hole.
Using a 150mm steel pipe, cut a ring 100mm long, centre and weld from inside the ring.
Flue housing complete.
The pot i have made from some flue housing, and a piece of flat steel welded on the base.
I have also welded a couple of pipes to keep the pot on the stand.
You could use a stainless steel mixing bowl with a 50mm U cut on the top edge for the blower / burner tube to sit into, rather than the hole.
I have drilled a 50mm hole in the side of my pot to house the blower burner unit.
To get the hole correct, in the side of your cylinder, measure from the floor up to the top of the hole in your pot. Put that measurement on the side of your cylinder. Drill a 50mm hole or cut a 55mm x 55mm square.
The blower/burner pipe will poke through this hole and bolt onto your cylinder or weld it .
This is how it works.This one is in a 18kg cyinder lying flat, so you can have the upright or horizontal.
Upright is best if you are intending in putting a copper coil in it.
