Chinese Diesel Heaters

[Puddleduck]

Asking this for a friend but it may be useful for anyone else who has one.

The friend has a stand alone diesel heater for his static caravan and it doesn't appear to start up. There is diesel in it and the power supply is correct. The pump and fan work individually when instructed to do so (but not together - not sure if that is relevant).

It does not appear to ignite at all.

When the heater is switched on the fan runs for a short time (a minute or so) and then switches off, maybe that is normal and because there is no heat to blow around.

The pump only works if told to do so via the controls / remote control.

The instructions are rubbish and in such poor English that Chinese instructions would have been more intelligible!

Any help gratefully received.

Is the heater plug working?

There is power to it if that is what you mean. That is what drives the pump and the fan

if the glowplug fails, it wont ignite

This may help,not enough power to glow plug?

Chinese Diesel 12V heaters { Similar to eberspacher / Webasto }

Just fitted one of these diesel heaters to My Iveco Box Van Motorcaravan Conversion. FULL KIT = circa £114 off ebay. 5KW of heat. Bench tested first. { Watch out for import charges, try to buy from a seller that posts from the UK } 2KW, 5KW, even 8KW are available. Really throws out the heat...

Enough current to work the glow plug (takes around 12amps at 13.6vdc)?
Air flow for both room heating and intake/exhaust - check blockage or filters.
I don't think these all in one units come with a fuel filter, so a fuel blockage possible.
Glow plug failed - this might be shown as an error on the screen?

Those are the four things I'd check first. I think. As always, could be something else too

 

[Puddleduck]

I'll get Martin to go round and ask him to check all those things. The simple things are usually the most likely suspects - if you know what the simple things are.

You are all stars!

The man has a static caravan on the building plot next to us and I think his wife will move out or in with us if he can't get the heater going!!!!!!

Press 'Settings' (the cogwheel) and enter 9009, then go through the options and check the LCD is set to 12V.

As noted check the gloplug.
If it was powered down when disconnected from the supply it may have fried the ECU inside so check for melted bits.

Has he primed the pump?
My mate had one and the pump was working but there was too much air in the system.

Yes, that was the first thing Martin checked when our friend asked for help. The fuel feed line does do an upwards loop though so I wondered about an airlock.

I think the power supply is probably not up to the job so have suggested he sorts that out first. If that doesn't work he will come round to watch you tube and have a look at facebook.

I thought our travelling vans were complex but the static takes it to a whole new level - an ex-rental van that he bought cheap to live in whilst he built his new house but I think he's spent more time sorting out the static than working on the new house Too many bodged / cheap repairs by the previous owner.

 

[Puddleduck]

Many many thanks. Martin is going down to see if he can get it sorted

Is it coming up with any fault codes

 

[Puddleduck]

Our friend was called out yesterday evening and was out most of the night so is sleeping at the moment. When he is awake we will see if we can get the heater going. I think the power supply isn't up to the job or / and the glow plug needs to be changed but we will see.

I don't know about fault codes Enword , I have problems reading LCD panels after my rentinal surgery Quite literally the uninformed leading the blind. lol I'll ask the men to read out any fault codes and will check them. I've printed out the fault code description you posted so they have an idea.

Very likely this - it needs to be able to supply 10 amps plus for a few minutes without the voltage at the heater dropping below about 10.5 volts. Supply cables need to be a good size and well connected for the same reason.

A point about the fuel pump: it only pulses when power is sent by the main unit and is used to vary the heat output. So basically it can't pump anything unless the main unit calls for fuel and even then will pump in single shots. So the initial purging of the fuel line isn't all that easy. Once done, of course, the run of the fuel line won't affect it.

 

[Puddleduck]

Yippee !!!!! Heater now working. As suspected the power supply wasn't up to the job.

Our friend is now going to put a fuel filter in and an extra fuse somewhere (don't ask me where - possibly on the input side before it attaches to the heater - I am not that technical).

Martin is so impressed with the heater he is going to get one for us in case we need it this winter. At the community planning meeting this morning (informal group of people who help out in their communities as and when needed) we were told that this winter is forecast to be severe and we should plan accordingly.

Our friend is very impressed at the knowledge on here and the speed and depth of answers. Once he has his house built he's thinking he might build a motorhome
