Interesting concept for a stand-alone rooting shed.

[PapaFig]

I have no idea about this retailer - but I saw this Dewalt cordless diesel heater when I was looking for a stand-alone solution for a possible separate structure for rooting in the winter (far enough away that if a fire did occur, it would not involve the main structure, e.g. house).

This would also eliminate the need for electrical (mains), a common cause of fires (I guess the batteries are LION, and electrical - so I'm still looking for a mechanical only solution).

Look into a Chinese Diesel parking lot heater.
I'm on my second year with one in my small greenhouse and have no complaints. It does use 120 volts but it's a low amp draw.
That DeWalt unit will be constantly using high dollar batteries. I can't imagine getting a long run on a battery charge having to run a fan and ignition source.

I'm also looking at the wick type kerosene heaters - like

I already have DeWalt batteries, but you're right, that would get old real quick. And not really what I am looking for.

We typically only have about 8-15 really cold days a year where I have been using one to 4 propane heaters, depending the temp. AI is telling me between propane, diesel and kerosene, kerosene may actually be the cheapest (per BTU). Again, back to local conditions, and is high grade kerosene even available locally to me.

I just got one of the Vevor 8KW diesel units, but it requires 12V or 115V - I've yet to run it but cold weather is coming soon no doubt.

I used one of these in my wife's small greenhouse years ago. I just used it for a few cold overnights in spring. It worked fine, but hauling and refilling with kerosene was kind of a pain. And be sure to vent the greenhouse before working inside after burning it all night.

Now kerosene is over $5 a gallon, so I don't know how economical that would be.

Right. I need to check around here - and for off-road diesel prices.
