Which chinese Diesel Heater to get?

[gaz1]

no low level or you will over heat it i see so many stuck high

think what happens with lcds and it does happen with any pcb board they over heat

everything is affected with them solder diodes and capacitors all over heating due to heat

What about here laid flat, vent slots upwards on a fully ventilated shelf

My old 2kw Webasto (great little heater) if I recall only draws about 1A when running, but when igniting that goes up to 20A!
In the camper it's drawing off the leisure battery so no bother, but for sure if off a PS then the PS needs to be man enough to cope with the start-up load r it'll go pop.
I have no idea if a bigger heater has a corresponding bigger start-up demand, or if they all use a similar glow-plug
I quite like the look of those PS, except for the open terminals. Especially having 230vac unshrouded terminals - that's more than a bit shoddy.
That said, it looks like they are designed to be inside a cabinet/enclosure as part of a built assembly rather than as a stand-alone unit.
Bunging one in a larger, well-ventilated GRP box might get the answer? I've done that with some panel-mount SMPS charger units with similar terminals to make safe to handle.

Yes I agree I'm definitely not keen on the exposed terminals. And it does need good ventilation maintained I would say. I'll search for a suitable electrical enclosure box.

Just get a cheap plain enclosure & either drill lots of small holes on top & bottom, or if feeling fancy, cut out bigger square sections and stick some mesh over

As said before if you find a 100/125mm pipe, fit exhaust and seal in one end, vent other end out side this way you get the wast heat from exhaust, a down slope on it forcondensation drain.
The PSU is ok if you don't have power cuts.
A battery and a charger are the best way

I've got a 30 amp psu and it barely gets warmer than ambient. Once the heater is up to temperature the psu is not being stressed by the demand from the heater.
My heater is wall mounted up high with the intake and exhaust going through the wall to the outside.

I got my heater today, trying to decide where to fit it in my double garage now:

 

[500e]

Why have the heating air inlet where there is a chance it will ingest exhaust fumes

Is that in relation to my post above? Or post #27?

If so I just sat it there out of box it's not installed. Yes exhaust will go outside through wall in my case. Combustion Air intake will stay inside doesn't make much different on that front IMO.

This is what I did with mine. No overheating, safe and works well.
I used a cheap enclosure from the local electrical dealer.

Mine fitted well on a metal shelf. I plasma cut a hole in the counter and routed the exhuast pipe down through that into a safer zone and cored it out through the cavity wall.

Air inlet staying inside is my preference.
