I've finally found the tuit to get a cheap Chinese diesel air heater
running in the workshop - it's great!
They have a reputation for being unreliable but that seems to be down to
switching off the power (rather than allowing the heater to use its
run-down cycle to cool things down), lack of a fuel filter, unfiltered
combustion intake air and (perhaps) flexible fuel pipe. The first is
easily fixed with a small 12V battery to back-up a 12V 15A PSU, if the
fuel pipe is flexible it's cheap to replace with rigid pipe, and filters
are obvious. Overall, highly recommended.

I think you're now supposed to get obsessed with generating the 12V from
a stack of peltier devices, running the exhaust through an old radiator
as a heat exchanger, and scrounging old oil from the local chippy ...

Agreed.
A diesel air heater allows me to do those jobs which don't take long
enough to warrant lighting the wood burner plus they give near instant heat.

What's unfiltered combustion intake air?
No filter on my air intake, just an end piece with slots to prevent
solids entering.
Or, are some people recycling the exhaust gasses by having the intake
too close?

My manual says that the power supply should be 20 amps minimum but I
prefer to overspec so went for a 30 amp model @ £22 similar to

Those all sound great fun, but life is too short (getting shorter by the
day!) and the list of jobs is growing (getting longer by the day!) so I
will resist the temptation ;-)

I've run the exhaust through the wall and put one of these
https://www.amazon.co.uk/dp/B0C5TRYR7N on the intake because I generate
a lot of saw dust.

I went for this https://www.aliexpress.com/item/1005002266393301.html?
with a small'ish (10Ah?) battery so that the heater can complete it's
cool-down cycle even if the mains fails. The control PCB is sat on the
top of the heat exchanger and (apparently) it cooks if the 12V supply is
disconnected when the heater is running and hasn't completed it's
shutdown. The PSU draws about 40mA from the battery when the heater is
off so I have a "hidden" DP switch which disconnects the battery when
the heater is isolated, for when the heater isn't being used.

Don't forget a CO alarm, those heaters are quite lacking in safety precautions

Thanks for the prompt, but I ordered one earlier today.
Quite a while ago an acquaintance nearly died in a light aircraft
because of a CO leak, it made me rather sensitive to the risk.

According to the link your power supply is 24v / 13.5a!

I see why you have a filter on the air intake.

I suspect that the shutting down problems are caused by idiot owners not
reading the instructions & following the correct procedure.

Not required in my draughty concrete sectional garage but for the little
they cost it would seem a prudent investment.

Strange. Apologies if the link is wrong, if you're looking for one then
search for SC-180-12

For everything you add though, surely there is a cost of some sort toward
the heating and cooling in the main system.
