The Chinese Hot Air & Water Heater (Truma) has arrived.

[Barry Pudney]

JP Combi Diesel Hot Air and Water Heater (Truma Copy?): As a few on this forum are currently building camper-vans I thought I would post this as an alternative form of Heating and Hot Water.

The JP heater looks to be a Truma copy or very close. Whilst the Truma Unit retails at a price that some may not wish to pay this Chinese version may be a good alternative and perhaps worth considering.

I took the plunge and bought one, however, I waited for a few months before posting this article as I wanted to test it and see for myself if it is as good as the manufacturer claims.

I know some Chinese suppliers don’t get good reviews but I have to say this looks to be a very well made unit, JP have been making vehicle heaters for over 20 years. So far its working great, I have had it for around 4 months and I cant fault it. It provides excellent heating, bags of hot water and is surprisingly quiet. I’ve connected it directly to my diesel tank, I am diesel and electric throughout and don’t use any LPG.

Gas or Diesel: You have the choice as JP make both. What is interesting is that the Truma Diesel version is a lot more expensive than their LPG version, if I am, not mistaken its about double the price. However the JP versions are the same price.

I decided on Diesel: Unfortunately LPG at the UK filling station is in decline, the distributors Autogas which is formed by Shell and Calor have already withdrawn a lot of their LPG services. You may find the following links https://www.filllpg.co.uk/ MyLPG (app) and www.drivelpg.co.uk useful for alternative sites.

Price: The price of the Truma (Diesel) is around £2500 depending on where you buy it. The JP Version (Diesel or LPG) is $950 (USD) Plus shipping.

Compatibility: The parts appear to be compatible (maybe identical) with the Truma. No doubt you would invalidate the Truma warranty but if anyone has a Truma heater out of warranty that needs parts then it may be worth finding out more.

I have already had people ask me about the JP Heater, the first person to ask me ended up buying one recently. I try to avoid putting links to my website in this forum but sometimes its unavoidable. The site doesn't promote any products, it cannot be found in google, I make zero from it and I dont include any personal email or contact details, its purely there to help, no more, no less. If you need info on A) where to buy? B) how long it takes to ship? C) what it costs? D) how to fit? E) how to connect a direct feed from your vehicle fuel tank to the heater?.... etc etc then the following links will cover these topics which are far too large to put in this post.

Hope this is of some benefit to someone.

One final point: I ordered the heater on a Tuesday and transferred the bank payment the same day. Payment was confirmed Thursday, heater shipped Friday (FedEx) Heater was on my doorstep the following Monday (total one week).

Good evening,Have recently made contact with JP in regards to whether they have developed there remote system yet?..On a separate note,was wondering how you did your curve...reason being mine isn't good and getting moaned at,so I thought I would ask you and that way I could achieve something.Shall await your kind reply.

@egg-fried-rice Looking at how you have yours installed, do you think you could have put it on a box built over the wheelarch to save space in the garage (assuming enough room over the top?
Only difficulty I can see is the stickyouty bit would have to go on the non-wall side - are there warm air outlets on both sides of the other end?

JP Remote: JP were working on the remote back in 2019. I held out for awhile as I thought of buying a unit with this feature. However, as time went by I didn’t feel it was that important. It’s nice to be able to turn on your heating from your phone from a remote location but as regards myself it isn’t that much of a necessity and I would guess there is an additional cost involved as well.

As of September 2020 JP hadn't launched the remote feature. My guess is that it’s imminent. I did check whether units without it could later add this feature and was told it wasn’t possible.

Curve: Not sure what you mean. Do you mean curves as in cutting the ply?

It’s possible but you need to check the height of the exhaust pipe. It must be a certain height above the unit (not level or below the unit and not too high), that may be ok if you don’t mind having the exhaust outlet higher up the outside of the van. Personally I could not have adopted this method because it would have made my bed too high (I have overhead cupboards in the back above the bed).

It doesn’t matter which way round it’s installed. I could have saved space had I turned it sideways but I planned on adding a service door under the bed to give me easy access to the pump and everything. Whichever way suits you is fine but do pay attention to the height of the exhaust, this is important.

These pictures should help you as they show the overall size against the Peugeot Boxer wheel arch.

Ah. That's interesting. Thanks. The other option I am considering is under a seat between shower/loo and driver seat. That way, all the noise is up that end. However, that means finding somewhere else for batteries.
I wonder if the over cab storage is big/strong enough for batteries...

 

[egg-fried-rice]

Under the seat may work providing the base isn’t a factory frame as it may not be high enough. If you are making your seat bases then that would work. Never seen batteries above the cab. The base isn’t strong enough without additional support. The large plastic tray only sits on the metal beam along the front (bulkhead side).

Nah, I mean a constructed box seat. If it's not a seat there, then it will be storage. So either way that works. I might need to run the batteries from the garage. Which isn't a problem, per se, just 2 long beefy cables. Although not that long, because it's only a MWB
