We have built a large outdoor fire pit approx. 5m away from the cabin / container - the container is lined and fully insulated.
What are ppls thoughts on using the outdoor fire - to somehow heat the cabin ??
The thinking is that if I scrounged some old 3' exhaust pipe, and placed an open end of it into / under the huge outdoor fire pit and then snaked that pipe (welded)under the ground a few inches, then came up, just under the floor of the container - back and forth a few times, before exhausting it downwind as to try and get it to draw - would this heat the container ?
Any other ideas on how we might best utilise an otherwise wasted heat source whilst we sleep ?

Just saying.

I'm not sure I see the point to having a big fire burning outside when you are inside anyway. Just build a small fireplace inside with a flue. Rose's dad built himself a furnace in a cut .44-gallon drum in his workshop. Because it has a fan blowing through the coals all the smoke gets directed straight out the flue.

If going the heat transfer thing by air, you'd be better served by doing somehow using radiant heat from the steel pipe...(not sure if that was your intention, but better that than to have hot air pumped in, as chappo said)
And to do this you'd probable need the hot 'exhaust' from the fire running through the pipe & the pipe through the cabin...
It would work im sure, but add other risks to the heating...such as smoke inhalatiin or fire given any internal leak.
Then there are building laws that require flue pipes to be sleeved to prevent injury & fire etc...
Also, im not sure how hot the ground would get below the fire, id imagine a bed of ash on dirt/sand is a pretty good insulator...so im not sure how much heat you'd get down below the fire...
Dont need me to come down & build the verandah...?...could do that upper deck at the same time...

I'm doing something similar with building a "Cabin" from a shipping container, I used a 40' high cube reefer as it's already insulated and the stainless steel interior makes it easier to clean. I'm going to use diesel heaters that run from 12v and plumb the intake / exhaust to the exterior.

You could do something similar, but run copper pipes into the cabin for the water to circulate, and radiate heat.

Correct, low oxygen levels is also a concern. But not a huge amount of ventilation is needed to ensure safety. Just two 12" square vents placed at opposite ends of the container would be plenty. Perhaps a door vent (down low) and a window left a jar.
