Has anyone used something like this
https://www.ebay.co.uk/itm/203591960310
as a workshop heater? I'm wondering about getting a portable one and
sitting it outside the garage or shed with the hot air outlet connected
to a pipe to take it inside. It would be useful to know how good the fan
is and what the 12V current requirements are.

Any particular reason for putting it outside? As I understand it these
things are all “room sealed”. Air for combustion and exhaust from/to the
outside (although I confess I’m not familiar with that unit).

Used it's older much larger brother many years ago. Basically a burner inside a large tube plus fan. It worked ok, but no CO or CO2 monitoring. If I had to use one today I'd ensure I had monitors.

It seems easier (and safer) to keep the exhaust gases outside and pump
warm air in than to have to get the exhaust gases out

Why burn diesel when kerosene is much much cheaper? The fumes coming
out of it will contain CO2 and maybe some CO.

They seem a bit coy about how you route the exhaust gasses out of a
vehicle.

I’m inclined to think that putting the exhaust gases outside would be a
good idea. ;-) It does come with exhaust and inlet pipes and *probably*
comes with instruction.

As long as you make sure that exhaust gases can’t enter the “room air”
inlet. You’re gonna need two holes in your wall either way. Two small ones
for combustion air inlet and exhaust if you mount it indoors, or two large
ones for room air inlet and outlet if you mount it outside.

Yes, they do this on diesel campervan heaters.

Why do you need an air inlet? The outside mounted unit gets a fresh air
supply.

Following up on other comments.

If you have your air intake outside, aren't you using extra energy to heat
(very) cold air up all the time?

Shirley it is more efficient to circulate the warm(er) air inside the
workshop unless you really want to flow air through (for example to remove
damp).

Yes I have one in my concrete panel garage workshop.
It needs a 20 amp start up power supply. I use one similar to these @
about £20
- https://www.ebay.co.uk/itm/224582753706
The exhaust must vent externally so I drilled a 26mm hole through a
panel just above floor level.

Very economical but has to work longer to combat draughts so the more
you can insulate the workshop the better.

It will only need one hole to get the hot air into the garage/shed if
it's mounted outside - I don't think many garages or sheds are
hermetically sealed ;-) so I won't need an outlet. I agree that it's
important that the exhaust gas can't be drawn into the air intake.
I think the plan would be to have a hole in the garage and sheds for hot
air input and to plug the hole when not required. Some of the left-over
soil pipe might be OK but I need to check its temperature spec.

My son fitted one to a camper van conversion, he had 2 holes in the
floor for in/out. I'd not thought of using something similar for a
workshop until a pal mentioned the idea a few days ago

Yes, that's a good point. Perhaps I need to investigate exhaust

Ouch! 20A! Do you know how long it draws that for and what the running
current requirement is? I'd hoped to use a small 12V battery.

a small lithium 11.1V battery will easily to 20A for a minute or so

Surely the more you can draughtproof. Draught proofing is the first step

As has been pointed out, then you’re constantly heating cold outside air
rather than warming the air in your shed. It’s very like a modern CH
boiler in that the air that’s heated is completely separate from the
combustion circuit and it’s perfectly safe to draw air for heating from
inside the shed.

No, the heater unit is mounted inside the van with holes through the floor
or wall to take in combustion air and for the exhaust.

Why would you want to keep heating cold outside air rather than heat the
air in the shed?

Well, I've just stumbled-on the answer:
https://www.youtube.com/watch?v=puvd9Z8zJFY I'm going to need a PSU so
it looks like the heater will be going inside with the exhaust, errr,
exhausting through a suitable hole

My car has something similar, to preheat the engine is cold weather. It
draws around 20 amps to power a glow pin, to initially ignite the diesel
for maybe 30 seconds, then drops to maybe 0.25amps to power its
combustion fan and coolant water circulation pump. That unit will not
have the pump, it will have blower fan and a combustion fan.

Ah OK. I'd have thought it'd be safer to put it underneath the van but hey.

You don’t *need* a heater, but it would be foolish to waste fuel and reduce
the effectiveness of the heater by always heating cold air.

I decided to buy a kit of separate parts, rather than everything
assembled in a metal box, so I could position things where I wanted them
(possibly an error with hindsight but ...). It arrived recently and I
was surprised to see that the Chinglish manual says "not to be used for
heating a garage", whereas: a boat, van, camper, etcetera are all OK.
Seems odd so I'll ignore it, but install a CO monitor. I presume the
restriction is driven by liability or run-time - any thoughts?
Now I need to core a couple of holes for inlet and exhaust and get
things mounted - but, ironically, it's a bit too cold at the moment.

The most effective workshop heater I can recall was a Salamander. I haven't seen one for years now. https://images.app.goo.gl/s8thr1Kvh6DoaBe76
