Heh, I came here to say the same thing! Would be quite interesting to see the difference between Diesel and Vegoil while it is starting. Then you could try heating the VegOil to somewhere around 60-70°C where its viscosity is not too far off of Diesel. Would be quite interesting to know what the failure point is. Burning temperature, viscosity/pressure, etc.

I've watched a number of your videos, David, and am much, much better educated as a result! Before then, these were just magic boxes working through who knows what supernatural means. Now, you have shown us that they are - at heart - really quite simple machines. I've just stripped and cleaned mine, replaced all the bits that need replacing and fired it up - off it goes. Couldn't have done it without you! One issue that keeps coming back to haunt me is exhaust length and build up of condensates and gunk. Mine's in a boat and needs a 6 metre run. So far, I can do no better than run it until it no longer goes and then clean/blast everything through with gunk so it works again. At least I now have the confidence to do it!

David, I'm an avid diesel heater lover. But one year in I have found a serious flaw with some All In One Units. It seems that some of the All In One Units used sub standard fuel tanks inside and several have spontaneously developed cracks, thus leaking a full gallon of diesel fuel on the burner unit and into my garage floor. I thought it was a bad hose connection but found that some of the very thin fuel tanks were developing cracks. As you can imagine, a full gallon of diesel fuel leaking anywhere, but especially onto a running hot burner could be a serious issue. This is one of the problems with low cost Chinese goods. You can sometimes unknowingly get some dangerous products. Thanks

Great video and no, it wasn't a waste, we all learned something from it. These heaters have incredibly clean burning and low sut accumulation. I was seriously thinking to make a water heat exchanger for one of these. It could help to rise the water temperature of a heat pump when it is very cold. I have 2000l water buffer tank and I heat it when there is sun or when the electricity is cheaper. It takes the water from the bottom, runs it thru coaxial heat exchanger where it leaves at 55°C max. I could add some 10°C perhaps and end up at 65°C. Worth a thought.

I really appreciate your effort, going so far as to cut the end of the burn chamber off. Opens up a whole new realm of uses and modifications. Do you feel that running the heater with the intake and exhaust to the side negatively affects the operation or lifespan of the heater?

I wouldn't have thought so. The diesel feed is just hitting the hot gauze and being vapourized before mixing with the air stream. Being on it's side shouldn't have any effect on it.

Why let all that great exhaust btu heat just get wasted. Maybe you could try this and see if it works? I was thinking about a 1" dia x 4' length.

@xvdd1 4 жыл бұрын

Whatever you decide to do with it remember that the more you reduce the exhaust gas temp the closer you will run to the dew point which produces acidic condense which is ok as long as you use material that is acid tolerant and you can drain the liquid.

@sirukin7849 4 жыл бұрын

Wouldn't adding a catalytic converter reduce the amount of NOx and VOC's present in the exhaust? Then, when you did produce acidic condensate in the exhaust you could filter it through another medium to capture any release carbon. Say, using the same idea as what they're already doing on large ships when using sea water to filtrate bunker fuel and illegally distributing it into sea water. A peristaltic pump setup on the exhaust end to pump the exhaust through a dirty water tank would cause any particulate to become trapped in the water. Like a dirty exhaust bubbler. Which, you could then send that dirty water to a distillation chamber setup on the exhaust itself since it'll be burning above 100 degree's. The water would steam off leaving concentrated toxic distillate or creosote. Which you could presumably use for something else. Like wood preservative.
