Those demon heaters have been around for years and are a great idea. I did look at quite a few DIY type oil burning heaters because I was looking for a way to use all our waste sump oil but in the end I was hesitant to use any heater wood/gas/oil that needs a flue up through the roof or wall and space is sort of limited.
But if this diesel heater doesnt work out ill go the demon heater for sure, they are priced well.
I have been watching the series of the Aussie bloke who tests the diesel heaters and while I can definitely see what he is talking about when he tests the larger unit I am not 100% certain he is accurate.
A couple of things that I thought were odd is that he wasn't using the ecu that came with the unit and he shut it down on the assumption that it would shut itself down when it reaches 120 deg however all the other videos I watched (including the one I posted) the person doing the testing clearly had readings of 150c or above out of the larger units for an extended period of time. And as for the fuel delivery from the pump yes using your own switch to test the delivery will give you the same amount of fuel because they use the same pump. He criticised other youtubers for testing the pump delivery in real time as the unit was running but in my simple mind surely thats how you need to find out how much fuel that particular units ecu is calling for? Doing it on a bench controlling the delivery yourself is only proving that the pumps are the same it is not showing how much fuel the proper ecu would be asking for.....(these little pumps just tick along and can tick along quite fast if they are being asked for more fuel)
And finally his suggestion that the 8kw are dearer may have been correct 4 months ago when he posted his video but they are now the same price as the 2kw and 5kw so that is also incorrect.
Im not saying he is wrong in all his findings, and in fact he may well be correct, the Chinese rubbish is like that but I just wanted to put it out there that he has some flaws in his reasoning
My little 2kw unit that I have been using for years often runs flat out for several hours at a time when I am drying my tent. Quite often when camping ill turn it on flat out an hour before I go to bed to heat the camper up. One night I had it on flat out, got in bed after having a few drinks and woke up around 3 or 4am drenched in sweat because I fell asleep with the thing running full bore
I would go as far as saying they much prefer to run high and hot than they do low and slow.........there are a lot of videos out there of people who have to pull them apart the clean all the soot out because they were not running them hard enough.
Again I am not sure that all the chinese heaters are made by the same company or if we are comparing apples with apples but I just want to make sure my real world experience is also put out there.
I may well be looking for flaws in his arguement because I just bought an 8kw and I want the bloody thing to be 8kw LOL but not really, it doesnt matter too much either way 5kw or whatever, a little heater like this will only take the chill out of the air down here anyway I reckon, I doubt itll be toasty warm like a wood heater would be, but again for less than $200 its worth giving it a go. Hopefully I can report back this weekend if it arrives this week
Thanks for all the comments, I am definitely leaning towards the Demon Heater moving forward if this heater doesnt cut it.
