  Hi John ,once there primed do they stay primed or is it every time you start the heater You need manually prime the line ? Hope thats not a silly question..thanks mate.

  Thanks John for all the effort you have put into these videos I am about to do an install of my supposed 8kw ebay heater but I'm guessing it's a 5kw (going of your review a few episodes ago) but that's still okay for $110 bucks. anyway a big thanks for all these helpful hints. Love your work 👍

  Why not leave off the hose and just put the filter directly on the air inlet? Is there a particular reason why they cannot be done?

  You could do that, but you would need a custom metal filter so the exhaust heat does not melt it. JMcK

  Thanks for your input. Interesting stuff, these heaters, for those that have a technical interest. Don’t get me wrong, a 2 kw heater has a place in many installs, but my view is it is better, noise wise, to have a bigger heater running slow, rather than a small heater running flat out to produce the same heat. Cheers. JMcK

  Thanks for that info and link. Fuel consumption is totally dependent on the pump dose volume and Hz rate. When comparing heaters you also need to look at the output air temperature and output air volume. Thanks for your input. JMcK

  Hey John, just been and looked at a video on fuel consumption for a 2Kw heater kzread.info/dash/bejne/m6l5p4-Jc5XKnKg.html His findings are completely the opposite, and at maximum output, his heater used exactly HALF (200ml/hour) the amount of diesel of a 5Kw heater. I watched another video a week or so ago of fuel consumption on a 5Kw heater on full blast and it was 400 ml/hour. So seems there's a huge difference in fuel consumption between different 2Kw heaters. Some are throwing diesel $$$ out the window while others are using a proportionate amount relative to their output.

  @Mancavedweller112 күн бұрын

  Thanks very much John, fantastic information. The first thing that shocked me with the 2Kw was the main inlet fan being the same diameter, yet the housing body being so close to the outside of the fan. Looks like that alone would restrict the airflow. You can see the much larger space around the fan in the 5Kw model. I've just bought an "8Kw" heater (I knew it would only be really 5Kw), and was also going to buy a 2Kw for my boat cabin, but now I wont do that. An interesting question is, "Where is the extra heat "vanishing" to" ??? If the same amount of fuel is being consumed, and the burn is very efficient, resulting in minimal CO, then the same amount of heat MUST be being produced in the burn chamber. I wonder if it's all going out the exhaust ???????? Might be worthwhile checked the exhaust temperature too. Of course the heat would be a combination of exhaust air flow and temperature, so to get accuracy both would have to be measured, but that might melt your anemometer LOL. I wonder if the smaller fan rotates faster and move air through the burn chamber faster, and thus give higher velocity air out the exhaust.

  Hi Brett Sorry for late reply, but currently sailing in the Med. Not sure what your issue could be without seeing the set up. But three main issues will shut down a heater. 1. Fuel issues. Look for any fuel problems, eg filter, pump orientation etc 2. Overheating. Are you running it at full power? 3 Low voltage. A very common problem I see. These heaters are supplied with wire that is far too small for heater operation. I suspect this may be your issue. Suggest you run heavy cables from heater direct to a fully charged battery and try that. Good luck, and please keep me informed. JMcK

• 
  @johnmck1147Ай бұрын

  Hi there It is ok using normal fuel hose from tank to pump, but from pump to heater, unless a VERY SHORT run, it is much better to use narrow bore hard nylon fuel hose. In these heaters the pump “pulses” diesel to the heater burner atomisation screens. Soft fuel hose from pump to heater absorbs these pulses resulting in poor atomisation and carbon build up in the burner. When sufficient carbon has built up heater won’t work. JMcK

  Hi Peter If you have installed 4 of these heaters, I assume you do not have restrictions in the set up. Without actually seeing it, your issue looks like a very bad fuel/air mix problem. If install is good, you most likely have program issues, or burner issues eg no atomisation screens installed. If heater is new, suggest you send it back for a replacement. It is not worth the effort trying to rectify these issues. JMcK

• 
  @johnmck11472 ай бұрын

  Hi Jay, It is good practice to ALWAYS fuse every positive wire close to the battery. Its main purpose is to protect the wire loom. If you have some failure short in the heater, or even a wire chafe somewhere in the wire loom, you will have significant current flow in the circuit, causing massive heating, which will, not can, cause the wire protective coating to melt and catch fire.

  Hi John, Really appreciate your effort in all these videos. It gives many of us "instant knowledge" to tackle our own foray into diesel heaters. I was wondering if you could expand on connections of exhaust piping. You covered connection of fuel quite well and it would be nice to see your take on the best way to connect the exhaust pipe to muffler, bend the piping, extensions etc. The pipes that come with the kit are hard to interconnect and I have seen a suppliers manual that suggest cutting a slot in pipes prior to connection to allow "pull down" by the clamp. With your experience would be good to see what you think is best for sealing and longevity. Great videos, thank you again.

  Hi There, You can cut slots in the exhaust pipe end to allow joining. Use exhaust sealer or high temperature silicone to make the join gas proof.
