Obviously the amount of fuel burned per hour is dependant on how hard it is working. These type of diesel heater are usually fitted with a pump that uses a piston that delivers 0.022mL per stroke. The controller is set, usually between 1-6 Hz, or in other words 1 to 6 pumps per second. There are 3600 seconds in an hour, so this means that at a low setting of 1Hz, in an hour the heater will consume 1 x 3600 x 0.022 = 79.2 mL. At a high setting of 6Hz it will consume 6 x 3600 x 0.022 = 475.2mL, or nearly enough half a litre going full tilt. Listening to the pace of Andy's pump in the video, I'd say he's got it running somewhere between 1-2Hz, (listen to the ticking) which pretty much matches the calculation, so you can just work out how much you will use with these heaters, it is about 80mL per Hz per hour.
Using kero at around 75ppl with the unit on high you get 4kw for around half a litre per hour ie 37pence . Drop it down to medium and you get 2kw for less than 17pph . Last winter I rarely ran at full tilt unless it was way in the minus. It took a lounge diner from 17 drgrees c to 21_22 in about an hour. They are not perfect, occasionally a bit of a pain, a little smelly and definitely louder that say a dryer . But you will save money, can dry clothes on a clothes horse and your definitely in charge. So not a cure all but drfinitely does work and we saved probably 2_300 last year on gas.
The kerosene burns best at 5-10 degrees ambient air temperature, it burns just over 165 degrees and is best burn ratio at 1.4 hertz. If you put say 20 degree temp into the burner it actually drops the burn temperatue due to there being less combustible material in the air. Similar to an egr valve in a car. The additional benefit is positive pressure in a house pushing moisture out of a property and stopping damp etc.
@@slarratt i was thinking to recirculate only the air that is in the room,and reheated and not to bring cold air from outside , the air inlet and exhaust needed for combustion will remain like that.
Im surprised that you have not got an Afterburner controller by now.... I have one and they are worth there weight in gold as you can set timers and much more i also have a silent pump on mine and save even more on the use of fuel... Both are well worth getting..
Hi, there is a central heating oil called 35 second gas oil, that is virtually diesel ( very similar viscosity ) don't know the price at the present but may be worth checking?
@@ralphfell2119 Correct. 35 second oil used for heating is quite simply Red Diesel. For those who wonder about the 35 second label, it is a measure of the viscosity of the fuel. The test is to allow a given volume of the fuel to run through a precise orifice at atmospheric pressure, just Gravity (NO Pumps used or involved). 35 seconds is the time taken for that particular fuel oil, as a measured quantity to flow through the orifice. I'm 76 and did that stuff when I was an apprentice about 17y/o and I cant remember the exact details but that's the principle of how fuel oil is graded for viscosity.
Don't forget the cost of the electricity to add to it, unless you managed to figure out the solar panel some to use. But yep agree it is cheaper than other types of heating.
@@flitsies These heaters sit somewhere between Gas and electricity in terms of price. 1 litre of diesel contains about 10kWh of energy. Right now diesel is about £1.50 per litre, so that means if you buy diesel to burn in these heaters it will cost you 15p per kWh. Right now prices in the UK are about 5p per kWh for gas and 25p per kWh for electricity. Price wise, you are probably better off heating with gas than you are heating with a diesel heater, however they make great alternatives for space heaters over electric fan heaters.
@@flitsies Also, the amount of electricity these heaters consume is basically insignificant when you compare to electric heating. They only have to run the fan, pump and glow plug. The glow plug draws a bit of power but is only on during start up and shutdown for a very short time.
@@shmavitz Yes you may be correct, this google thing tells you one thing then it changes, now it is saying 7.42 per kwh. Electricity is more expensive at the moment but in time it will become cheaper as it is so much easier and cleaner to produce or could be.
Not getting where the fresh air for combustion comes from, where the fumes go, and where the air for heating comes from. The warmed air is shown going through the wall.
The air is drawn from inside the box, the exhaust is outside and behind the box, the silencer can be seen poking out just about, the super heated air goes also from inside the box but goes between the plastic box housing and the heaters fins that lay underneath. Any other questions give me a shout.
I had the same problem , changed the silicone gasket on the bottom where the air intake/exhaust is , the ones on them seem to be more plastic than silicone , seems to have solved the smell issue , hope this helps
Check inside the casing, the should be small packers that separate the plastic body from the heat exchanger, if they are missing or dislodged, the casing can burn on the hot body ?
Afternoon Andy.. question i can't seem to find anywhere to buy kerosene. Just wondering if you buy yours from a supplier. I'm in evesham Worcestershire so I'm guessing within an hour of you. Any help would be great.
kerosine kills the diesel heater eventualy the reason is diesel hold more lubricant than kerosine prolonged use with kerosine will kill the heater suposedly there are some lubricant that you can add to kerosine to make it act and burn like diesel
@@durk541 yes and no i watched it on you tube from 2 videos one of the vids was from a guy playing with chinese diesel heaters and is like ok i used only kerosine now my heater is broke finished i dont know the exact title of the video now the other video was about right or wrong can you use kerosine again i dont know now the title if you search a bit you for sure find them but i understood the video about diesel versus kerosine kerosine is type 1 diesel believe it on not and diesel roadfuel even red diesel is type 2 diesel diesel is thicker and has lubricants in and kerosine thinner as it distilled petroleum lacks lubricants as far as add lubricants it was not specific of what you could use
actualy i also have a kerosine boat heater a wallas sail power 1800w diesel in that does not work and the actual process of burning kerosine is different the wallas is a catalytic burner so it burns kerosine and has a kind of afterburner much like a zibro kamin petroleum heater
I chuck in 1mL of two stroke oil per litre of kerosene to help lubricate the pump. Works great, doesn't change the burn or smoke at all and I haven't had any pump failures since doing this.

Now you are heating cold air from outside, do you think will be more efficient to have a recirculating air circuit of the air from inside?
That's a interesting thought.
The kerosene burns best at 5-10 degrees ambient air temperature, it burns just over 165 degrees and is best burn ratio at 1.4 hertz. If you put say 20 degree temp into the burner it actually drops the burn temperatue due to there being less combustible material in the air. Similar to an egr valve in a car.

what is that
Hard to fault these financially when most other home heating options require such enormous outlays of cash up-front to release their 'savings'.
Hi, there is a central heating oil called 35 second gas oil, that is virtually diesel ( very similar viscosity ) don't know the price at the present but may be worth checking?
This 35 second gas oil is for oil fired boilers and the viscosity is the same as diesel, it is available from oil heating suppliers

@@shmavitz OK just googled the price of gas per kwt and it is £5.48 in the UK.
That's very expensive compared to the diesel heater.
@@flitsies sorry you are mistaken, read again, I think you will find that is 5.48 pence, not pounds so £0.058, which is pretty cheap.

The heater I have still smells when on any ideas. It smells like burning plastic???
I have this issue as well. I think you might have a spillage somewhere. Try thoroughly cleaning the whole thing every nook and cranny.
I had the same problem , changed the silicone gasket on the bottom where the air intake/exhaust is , the ones on them seem to be more plastic than silicone , seems to have solved the smell issue , hope this helps
Takes a few weeks to burn off the oils , try washing with soapy water.
One of the common causes is tiny spillages when filling tanks. You have to be scrupulously clean and careful or it will stink for ages.
Check inside the casing, the should be small packers that separate the plastic body from the heat exchanger, if they are missing or dislodged, the casing can burn on the hot body ?
Must be getting cold there again
