Man-cave diesel heater 12V supply......

200ppm CO might be life-threatening in long exposures. 50ppm is the recommended maximum workplace 8 hour exposure limit. I fully accept the idea of taking precautions to minimise exposure to carbon monoxide, as it will not be possible to tell when there are pockets of accumulation that exceed safe levels.

You do whatever you want, this forum is incredibly popular and often ends up at the top of Google searches

The purpose of my post is for those searching who may land here

That is the reason for post #74. For those without common sense who can't be trusted to make their own assessment.

Stuart is 100% correct combustion intake and exhaust have to be external, it's possible for fumes to leak back also you are consuming the air in the occupied part


If it makes you feel any better I was trained by webasto, company requirement so we could keep our warranty.

Last incident I attended, after the appliance was isolated was still reading 80,000ppm

A modern boiler can produce 350ppm continuously

I would hope, but not expect, these cheap chinese heaters to burn that cleanly. They do not ‘soot-up‘ for no good reason - that is incomplete combustion manifesting itself, without any other clues/measurements/etc.

Where I worked, many years ago, the free oxygen in the exhaust gases was taken as gospel that the plant was operating under oxidising conditions. I always pointed out to the newer operatives that the CO readings were a useful guide because the kilns registered CO at sometimes different oxygen readings - poor analyser calibration, air leaks before the sampling point at the kiln exit, etc.

I think the flame impingement during cold starts contributes to the sooting, the heat exchanger will be very cold after being in a garage all night

I didn't want to put my analyser into the heater as it was a rather expensive piece of kit that I only used on gas so I don't know the CO ppm

I think the quality and grade of fuel people put in them have something to do with it too. Ask a collective what they use, you'll get kero, diesel, old diesel, heating oil, turbine oil or other substances as answers.There's videos on youtube where people are converting old tyres to fuel to run their heaters on using pyrolysis, can you imagine what their exhaust output is like and coating the burn chamber with rubbery soot...
