Chinese Diesel Heater Exhaust Waste Heat Recovery

Using a large old steam radiator to recover waste heat from a chinese diesel heater. Works great with no moisture buildup in the system (has a drain and is inspected periodically) or excessive carbon buildup in the heaters burn chamber. No drawbacks found after 2 previous winters of frequent use.

What is that radiator out of? Never seen one like that before. Interesting!

I saw your comment about yours on another video which lead me here. For an RV, I wonder if it’s possible to effectively exchange the exhaust heat to heat water. Idk like extending the exhaust pipe and wrapping it around a calorifier or something

Thanks for posting this, I just bought a diesel heater. BTW I got motion sickness from that video, but good to know about the radiator heater mod.

I definitely need to improve my video skills, thank you for the input and for watching as well as commenting.

I would say.... with the short length of the exhaust going from the heater to the radiator.... plus running the heater for a long period, you really shouldn't have any issues. I also think you have pretty close to the optimum size of steam radiator for the application. Anything bigger would possibly lend to more condensation in the system. I like it. A good test may possibly be this upcoming week with the temps in Michigan, along with the high winds.

Yeah I need to find me one of those radiators if I get a diesel heater like this!

A good place to look is marketplace under "steam radiator"...there's usually a few around. Thanks for watching and commenting

Exhaust should be reversed? How does the condensation get out? Exhaust inlet up top, end exhaust on bottom. Just a thought.

The exhaust is warm condensate with the sound nearly eliminated. I've ran this for thousands of hours this way with no moisture accumulation. The exhaust entering near the bottom heats that cast iron to nearly 400 degrees which keeps the condensation as steam form.

I would expect the principle is the same as with a vehicle exhaust. If it's only run for short periods and then shut off, condensation will form and over time corrode the components. But if it's run for long periods and the components are allowed to get up to their operating point, risk of condensation is minimized and the components will last much longer.
