Chinese Diesel Heater Tube Test - Which is better?

[@pauldowninguk]

Those thermometers give different readings depending on how reflective the surface is. So shiny will read less etc.

[@TriStateOverland]

Yeah I figured I’m going to bring both tubes at the end of February when we snow camp and see what the real difference is in output temp at the vent inside the tent. That will be a more accurate comparison I think

[@pauldowninguk]

@@TriStateOverland Just put some black tape on the bit you want to read. 👍

[@brettdalbeth2623]

@@TriStateOverlandso what was the verdict after your snow camp?

[@TriStateOverland]

@brettdalbeth2623 I guess it has been a year lol! I use the black one. The heat loss isn’t bad at all and it works great. Plus it packs away much more compact.

To pack these hoses, i took a piece of 2" pvc pipe cut 2 foot long, drilled a 7/16 hole on both ends straight thru both sides of the pvc, about 1" from the end. Then put a 6" long, 3/8" threaded rod thru the holes sticking out both sides. The hose will be stored between the 2 threaded rods. One end got a nut on both sides of the rod, tightened eight down to the pvc, centering the rod to stick out equally on both sides. Stand the pipe up toward the ceiling, putting both feet on the rod with nuts, holding it upright. Grab your hose, slowly feed it onto the pvc, push down to collapse it far enough to imsert the other threaded rod thru the top hole. The hose will expand, pushing against the threaded rods, keeping the loose rod tight in the pvc. Now the hose is 2 foot long, on a sturdy mount, easily transported

[@TriStateOverland]

That’s an awesome idea!!

[@petertyckare3432]

I bought a similar black hose, 6 meters long, 18 US dollars. The hose was 80 mm, so I bought a reducer and hose clamp, 6 dollars, I am very satisfied, now I get the heat from the basement up into the house easily! Brand on hose "Sterr" (from UK) I live in Sweden

[@chrisharrell2449]

If you want a true temperature comparison. Paint the pipes matte black then retest the temperatures infrared on shiny surfaces is no good

[@TriStateOverland]

I am going camping in two weeks in the snow I figure I’ll take both hoses and test output in the tent at the vent and compare.

[@oojimmyflip]

lazer pointer temp guages dont work well with reflective surfaces and give false readings, youd be better off painting the reflective surfaces black to get a more accurate reading.

[@harrypierce1298]

Or install the hose vent on both hoses and aim the Lazer at the plastic hose vent

[@charlesd3376]

Yeah. Can't use a non contact SURFACE thermometer to read AIR FLOW temps.

[@harrypierce1298]

I use a 3i nch insulated dryer hose. Its 3inch i.d., but almost 6' o.d. the outside of my hose reads 10°f warmer than the room temperature.

[@Popcornbeetle]

Those black Chinese ducts have a toxic smell that doesn’t go away. Would avoid at all costs.

[@qgipson632]

I purchased the black one and your absolutely correct. the regular one doesn’t smell

[@TriStateOverland]

Mine did the first two times but after a few more uses it doesn’t smell anymore. I’m not sure if that means some coating “burned” off or what but it’s good now. And I’m not dead yet either so it wasn’t toxic 😂

[@robton007]

Do you have a link for the black hose?

[@TriStateOverland]

Yes, for some reason I thought I put it up there but... oops! amzn.to/3HhOoVa

[@wadematthews8547]

And is that 3” or 4 “ dryer hose

[@wadematthews8547]

Doesn’t the dryer one get hot ?

[@TriStateOverland]

It does but not as much as the black one. I should test both next time. I did use just the black one in Virginia recently and it still worked great. I think I like it better.

[@PainterD54]

I tried the expandable dryer vent that was plastic on the outside and it stunk like burnt plastic and melted where it was mounted to the heater. Don't use it. It's sopposed to be good for 300 degrees? Bullshit. Get something like aluminum or the cardboard that comes with the heater. .

[@donnied6759]

I bet it either would be Hotter if you shut the door and put the exhaust outside through a small hole. Feeding cold air doesn't help😅
