Cheapest Diesel Night Heater on eBay test / review

I bought the cheapest diesel heater you could get on eBay.

Here is where I’m going to share the results of any tests I do.


Fuel consumption:

Max 250ml per hour
Min 100ml per hour

Power consumption:

At 12 volts there is a start-up current of 10 amps.  This is to heat the glowplug and start the burn.  After a few minutes, the glow plug goes out once a self-sustaining flame has started.  Then power use goes down to 1 – 2 amps.


Difficult to measure in the workshop, it being a big metal box.  It’s certainly not silent, but you don’t have to shout over it.  I think once properly located and installed it’ll quieten down a lot.  Results skewed by having exhaust in test area.

Max = 70-80 dB
Min = 60-70 dB

Heat output:

Min or Max outlet temperature between 110 – 130 oC.  Higher settings results in more flow at the same temperature.

Questions from comments

Will it run on Kerosene / Parrafin /Petrol  / etc?

Kerosene – Yes
Parrafin – Yes
Petrol – Yes

Can it be run from a Li-Ion jump starter?

Yes.  It’ll start up and run.  The problem you will have is when the battery pack battery gets low and just shuts off.  The heater will just stop dead and won’t run the fan for the cooling cycle.  Damage to the unit may occur.

What happens when it runs out of fuel?

It stops and an error light is displayed on the controller.  You have to remove the fuse and put it back in again to get it to work again.

Will it stop if the battery voltage falls?

No.  I ran the voltage all the way down to 6 volts and it keeps running.  Anything less than 6 volts and it stops dead.  No cooldown, just off.  Damage may occur.

How do I prime it?

Plug it in.  Turn it up to max.  Press and hold the OFF button for 5 seconds.  The pump will start running.

      1. Hey brother you got a way fore me to buy you a beer over PayPal
        Least I can do for the help with my heater and entertainment value ps you sound like Robin Williams as misses doughtfire when you say hello oooo lol

  2. Hi. Love the videos. Many of the diesel heaters do not have the thermostat. Any chance of a video about retro fitting or working out the wiring for one ? Keep up the great vids.

      1. Hi. Sorry to be a pain. Do you have a link to buy one. All the ones i find do not have a thermostat function, only timer and oil pulse control to adjust temperature, which is what mine has. Thanks again

          1. Hi. Solved it. The lcd display was in pulse mode. You have to press setting button and up together to put it into temp control mode. That wasnt in my instructions. Cheers. Btw you did lead me to discover the good availability of spares for these heaters.

    1. 1 light – low supply voltage
      2 lights – high supply voltage
      3 lights – glow plug failure
      4 lights – fuel pump fault
      5 lights – overheating
      6 lights – fan motor fault
      7 lights – Break line fault (no idea)
      8 lights – flame out

  3. Will it run on gasoline / petrol? I see many of these units appear to be advertised to run on either fuel.

    1. Yes. The first time I tried running on petrol it didn’t work. But I’ve been messing around and the heater actually ran on petrol. Seemed to run a bit louder on petrol though.

  4. Hi dave ,

    Is there an possibility that the unit is connected with an external on/of switch,

    Because in low power setting It soots up the heater , I Rather connect it to an external thermostat . So that the heater only runs on ful power mode ,

    Thanx in advance !

  5. Excellent review buddy, very handy as looking to get a vw camper van, still not sure if van to convert or already done? Am in Glasgow so prob need to travel to get one so doing my home work any info u habe great. Cheers again buddy
