Diesel heater exhauat

View attachment 206180looks like I wll be busy on the boat. That could have been a disaster CO. I think what stopped it leaking gas was 2 layers of thick fiberglass wrap. New exhaust ordered

Was that the exhaust supplied with a chinaspacher? It looks a lot like the exhaust mine came with. I bought a good quality marine grade exhaust and relegated the cheap stuff to the air intake side, where it is safe enough, and better than the supplied aluminium intake hose
 
It has been said and tested that you'd have to sleep with exhaust in your mouth to get a measurable amount of CO from a diesel heater (I have put two different alarms by the exhaust outlet and not registered enough to sound) but definitely replace with a Eberspacher or Websato marine grade pipe and of course have a CO monitor - despite the tests some have done why tempt fate.

Not good, but I hope you would never run a diesel heater without a CO monitor on board.

I only use it dor a short time then turn off and I do have a CO alarm. I am guessing my over the top fiberglass wrapping kept it from blowing put so much.

I think it was one that came supplied with the heater cheap chinese one. Tempted to not bother re installing it now.
 
I bought one of the Chinese heater on EBay a few years ago for my Sealine. First thing I did was to bin the exhaust and silencer as they appeared to be made out of tin, even though the advert said it was SS🙄
Bough a decent exhaust from Webasto and never had any issues.

Always have a monitor on Kidde one, and to be honest never trusted these heaters. I never forgot years back a driver being pulled out of cabin that died from CO poisining.

Burning diesel does produce much less CO than burning petrol, but even a diesel heater is still very capable of producing enough CO to kill.

I don't advise taking any risks and always have a CO monitor and a good (ie not original Chinese ) exhaust - even if the CO on these is tiny in tests , a poor fan or any number of other things may change the burn and produce more CO.
 
I also fitted an Eberspacher exhaust tube and a proper silencer to my Chinese heater and not had any problems. One CO meter in the rear cabin & in the saloon.

Presumably one of the things that might cause a heater to produce CO is if the air intake is digesting exhaust gas - therefore screwing up the oxygen mix?
