I would recommend using a much shorter pipe with some kind of ribs/heat exchanger. too long of a pipe reduces the efficiency of the burner by delaying exhaust gases. You can extract more heat a get better burn by using a short pipe with a heat exchanger. Also i would not recommend painting it as it will release toxic organic compounds when exposed to such heat and delay the release of heat. Which is counterproductive. Just polish the pipe it will look great and release more heat.
It’s possible that you are seeing phase change from the combustion and it’s turning into water which is then blown along the pipe and turned in to water vapour again. If I were guessing you’d be better off with a large area to vent the gas into which has a lot of external surface area (ie lots of fins like a car radiator) and a condensate escape path at the bottom. Maybe get hold of a destroyed condensing boiler? All these things come with risks though so you are taking a risk with things I know little about so I wouldn’t. Best of luck.
good idea have seen similar
Thank you! Cheers!
Put a down angle on all them angles. So the water will flow out easier with the exhaust.
thanks andy
Each 90" adds 2m of pipe. It's not condensation but unburnt diesel. It will clog up. Best to use a cast iron radiator with 25mm diameter a minmum
Could you clarify what you mean, sorry - 25 inch diameter radiator?
@x-ray-automatic 25mm diameter, sorry. I tried with 22mm and caused white smoke. Unburnt diesel
did you see my other heater videos: www.youtube.com/@andyfireblade
let me know what you think
cheers andy
@@AndreiSuciu-p1s Got ya now - thanks!
Try run an egr valve cooler matrix from a scrap car, you can get them for £40
