JP Diesel Combi Heater Install and Test

[@thefirst555]

John - massive thanks for being somewhat of a UK Guinea Pig on this, mine is due any day now, and i your video and the timing of it is perfect

[@Magic-Smoke]

Lol! Glad I could help, Avi! I was pleasantly surprised at how easy it was to install and get up and running. The hardest part is probably deciding how to run the diesel line and where to locate the pump. I'm happy to discuss any aspect of the installation here. Please feel free to share it with any other groups you are a member of.

[@thefirst555]

Indeed. I'm not entirely sure how to tackle the connection to the tank either. Any advice appreciated.

[@Magic-Smoke]

@@thefirst555 Depends on what kind of van you have. I have a Fiat Ducato. I didn't use the supplied tank pipe, I got one from Ebay since it was easier to fit. There was enough blue tube to get to the outer cill behind the driver's seat. I put the pump and filter in the 'gulley' between the cill and the longitudinal beam, mounted on a 3D printed bracket.

@@thefirst555 Turns out it was Aliexpress (link in the comments). Also worth watching kzbin.info/www/bejne/qmq6eJedfqiap6s - he shows the tricky bit!

Great Video! We are about to install ours, can't wait to have it up and running. Excited to see your plumbing video, hope you'll have it up soon before we get to do ours :D

[@Magic-Smoke]

I've had a bit of a delay with my kitchen but hopefully ill get it 'wet' in the next few weeks. Wishing you luck with your installation- post pics when you can!

[@davidbell5754]

Hi great system one thing that I fitted was a pressure gauges so I cud adjust system pressure and not rely on pump switch micro switch

[@Magic-Smoke]

Ah, that's interesting...

[@andreoorthuys4200]

Great video. Can you compare the noise of this item compared to the original Truma ? To me it makes a little more noise , or?? Thank you

[@Magic-Smoke]

I really don't know. I got the JP Heater since there were no Truma D6 available in the foreseeable future. I've never heard a Truma

[@michaelfornallaz8705]

Do you still have a vibration noise coming from the exhaust after fixing it? Because I have this problem that bothers me. Thank you for your advice. 👍

[@Magic-Smoke]

I don't have any vibration from the exhaust although there is sometimes an occasional little 'tinkle' from the fan.

[@rayleeson6135]

Hi John I’m looking at your video and I’m going to go with one too….can you say what the import charges were …or the % of the total you have to pay.

[@Magic-Smoke]

Hi Ray, I can’t remember but it was all very efficient at the time - there is a Facebook group where you could ask those that have done it more recently - JP Heater Group.

[@rayleeson6135]

@@Magic-Smoke yes just applied to join, the one I will purchase will probably be the lpg model, the same as my Truma 6e…. The cost is circa £668:00 but I just wondered how much additional money it was once it arrived here..

[@Magic-Smoke]

@rayleeson6135 I got the diesel one and it all came to £1100 at the time but I recall the d6E being about £850?

[@rayleeson6135]

@@Magic-Smoke Thanks John that’s very helpful.

[@Kn0bby]

Strange how the JP uses the normal exhaust abs the Truma version uses the rectangle version with additional fans.

[@Magic-Smoke]

Yes, i wondered about that. Not sure why the Truma has the extra fan apart from perhaps to 'eject' the exhaust further away especially during startup and cool down.

[@Kn0bby]

@@Magic-Smoke can you smell fumes inside the van? Obviously the price is attractive but also having a smaller fan is a bonus.

[@Magic-Smoke]

With the doors closed, I've never had fumes in the van. I have run it with the doors open and it depends on the wind 😂

[@w.schmidt323]

@@Magic-Smoke Truma needs the exhaust for the muffler. Thats the different in my eyes. But JP worth the money.

[@sukrugokyar2200]

Great video. Have you ever test fuel consumption just for air heating, water heating and both together in 24 hours?

[@Magic-Smoke]

Sukru, I have not done that test and I'm not sure how compelling it might be as a video - lol. I'll have a think about it and see how best I might do it. Thanks for the idea. Of course, consumption will vary with Temperature and insulation as well as how long it takes you to wash your hair 😜

[@TAR412]

Hi John. Have you run the 230V side direct from mains/shorepower or are you running it through an inverter? Thanks

[@Magic-Smoke]

I have done both. Initially I tested it from the inverter and battery - it uses a little under 1900W. It works the same with mains 😊

[@MastaSquidge]

When air heating, does this alternate the output between high and low like a cheap Chinese diesel heater or does it automatically vary the pump rate to adjust heat output and stay consistent?

[@Magic-Smoke]

Once its up to temperature, the 'tick rate' of the fuel pump lowers so I guess it moderates the output that way. Once up to temperature, the burner goes out and the fan continues to blow but at a reduced rate until the temperature drops a little and it all lights up again.

[@MastaSquidge]

@@Magic-Smoke Yeah that sounds like what they all do. The problem I have is that in smaller spaces they bounce between low/idle and high when it calls for heat and when on high it almost instantly overheats way past setpoint. If that's how these run then I'll need to stick with the cheap diesel air heater and aftermarket controller I've been using.

[@Magic-Smoke]

I've never noticed that problem. I think the benefit of the water tank may be that it doesn't have to cycle on and off too much at all

[@kaym.1489]

Is the heater still running without problems or were there defective?

[@Magic-Smoke]

Never had a problem with it at all. Works great!

[@peterc2248]

Are these available in the UK? If not, how/where can I buy one please?

[@Magic-Smoke]

Hi Richard, there is no UK stockist so we ordered direct from China. There is a Facebook group where you can ask direct questions of the manufacturer beforehand. Search for JP heater. If you are unsuccessful, please come back to me

[@peterc2248]

@@Magic-Smoke Many thanks for that, best regards

[@Lennart942]

This was really interesting. Because i can se that mine uses more power than this. I use it in my car, witch i use like a small mobile home. I got a 95 amh batteri, and 45 is used in 10 hours.

[@Magic-Smoke]

You maybe have some other background loads running? Also, don’t forget that the Ah measurement from a shunt is only an approximation and the accuracy depends on the accuracy of the shunt

[@Lennart942]

@@Magic-Smoke i do have a small tv. But i tested the heater with the tv hooked up to another battery. Im surprised that even with the lowest program, the fan blows at high level. And when i use the temprature settings, the heater cools down all the time, and use alot of power starting up again, i guess. Wish there was a setting, where the heat, and the fan runs very low, so it dossent have to cool down. But i just got it, maybe theres somthing i diddent figure out yet.

[@Magic-Smoke]

@@Lennart942 ah, I see. On mine I have a separate fan speed. It has an eco setting and is possibly what you are looking for.

[@Lennart942]

@@Magic-Smoke thanks. Mine dossent have that. But i should be able to control the fan speed, in the menu. But nothing happens. I will se if i can get a manuel one then. Thanks

[@chukleberryfinn]

Hi John, did you connect this up to your van's diesel tank?

[@Magic-Smoke]

Hi @palnoch, I connected straight into the top of the tank connector using a pipe I bought separately (fleabay) since the one supplied had too large a diameter to fit into the tight area on a Ducato fuel tank top.

[@chukleberryfinn]

@@Magic-Smoke I’ve also got a Ducato. Would love to see how it’s done!

[@Magic-Smoke]

I didn't make a video of it. The best video I saw was this one. kzbin.info/www/bejne/qmq6eJedfqiap6s The best advice I can give is to check all your clearances - it will be a tight fit. Others fit them to the van supply but I wanted to keep the 2 systems as separate as possible. Let me know how it goes :)

[@chukleberryfinn]

@@Magic-Smoke thanks John. Last question - What do I need to buy from eBay ?

[@Magic-Smoke]

@@chukleberryfinn Lol - ask as many questions as you like :) I got one like this: tinyurl.com/k65dcty8

[@MrIRmss]

Hello John, I got mine installed as well. But when I test run, there seems to be a problem with my diesel pump. I tried to force it with the OilGo feature. Even the filter isn't soaked. Any solutions for that problem? Thanks in advance!

[@Magic-Smoke]

@Rmss Hmm, I found that the pump pulled the fuel through wthout a problem. However, it would be worth making sure you have no air leaks in the pipe between the tank and the pump. Are you able to suck fuel from the tank through the open tube? (I think you're in the USA? You can get a cheap bulb-type pump from Harbor Freight to suck the fuel and prime the tube). Another way to test this is to use a short offcut of tube and dip it into a jar of fuel right by the pump - have the jar as vertically as close to the pump as possible. Let me know how it goes!

[@guntherdumphart8369]

Hello John Are you still satisfied with the heater Im thinking of replacing my Truma C4 with the JP Diesel heater Thanks in advance Guenther

[@Magic-Smoke]

Hello Guenther. Yes, I'm happy with it so far although I have only used the air heater function as the water system in my van build is incomplete. I hope to have it 'wet' in the next few weeks and will post an update.
