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.
We have found restricting the hole size to 100mm x 100mm square helps with cleaner burning rather than cutting a 150mm or 6" round hole.
Using a 150mm steel pipe, cut a ring 100mm-150mm long, centre and weld from inside the ring.
Flue housing complete.The flue will now sit either inside that ring or if your having a flue made then get them to make it to the outside measurement of the ring, especially if this heater is having it's life outside, as it will keep any water out.
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. If using a bent nose burner / blower unit keep the burner end 80mm from the bottom of you pot.
The blower/burner pipe will poke through this hole and once fitted bolt the blower burner unit onto the side of your cylinder.
This is how it works.This one in the video above is a 18kg cylinder lying flat, you can have them sitting vertical or horizontal.
Upright is best if you are intending in putting a copper coil in it.
This waste oil heater in the video above, although installed outside, heats a 2.5 metre radiator in our lounge to 70-80c which heats the house for free.
It's fitted with the new timer/pump, which makes it just works beautifully.
We would highly recommend that you purchase the timer/pump system to make your waste oil heater fully controllable and safe.
We have Wifi with this heater to control it on/off, so we don't have to go outside at night in the wet & cold, we can turn it off in bed via the phone App.
There is a little to outlay at first, like with any heater, but once you have this setup, that's it for years and years or until you let it rust away of burn it out, our heater has been going for ten years it live under a piece of tin to keep the weather off it but it doesn't look any different from the day we installed it to be honest.
Pretty much totally free safe heating and that's got to be worth alot to most families.
All you do is light it, so start enjoying that free heating forever as alot of us already do.
