Truma Heater Conversion

[starvin marvin]

Just wondering if it is possible with a gas only Truma heater/boiler with the the usual blown air fan, circa 2002, to be converted to accept a mains electric water heating element?

 

Our previous 2003 van with a Truma as above, had the electric heating element, which we found quite useful.

 

Thanks

I believe the answer is yes. There is an add on that uses a wrap around element and control unit. As to availability and cost I have no idea but have seen it in the past. I have toyed also with the idea of disassembling mine and cutting a hole in the stainless steel drum for a heater element, fitting of thermostat etc but never got round to it. The Wrap around heater seeming to be the better option.

For Truma Combi units there was an electric heating element listed by Truma.  Have a look on their website.  I think the cost was around £200.  However, before going too far, check that you have sensible access to get your Combi out from where it has been installed.  Not often that easy!

Just had a look at online catalog, cannot find the addon heater accessory now...maybe I am looking in wrong place.

Thanks for the replies, they're useful. I'll have a look at the Truma site.

 

Thinking aloud about it, I seem to recall that the Truma factory (if its still there) is close to the jcn A38/A50 near the JCB factory at Rocester, which is not too far from me, I could call in on the way to Ashbourne in the Peak District, if its still there, but not just yet awhile!

 

Thanks again

The gas only water heater on my 1992 Hymer packed up, as I prefered dual heating but did not like cst of a new unit went on Ebay and paid around £200 for one out of a three year old written off caravan. Fitted it myself, works great.

I believe that the reto fitting of the electrical element was covered in MMM a few years ago but I don't have the back issue.

A friend of mine as just had the Truma electric heating collar fitted to his Burstner. Cost was £300 inc VAT and fitting

Is this what you are looking for?

Just to clear up any misapprehensions of what this collar will do for you, it will heat the water, slowly but it will not provide electrically powered blown warm air. The C series heaters with built in mains powered heating can provide warm blown air because their heating elements are inside the warm air chamber. This heating collar fits around the outside of the water heating tank and therefore will only provide mains powered heating of the water.

P.S. cost of fitting will be dependent on how difficult it is to access and remove the heater unit from the motorhome.

Going off the thread a bit, we have a gas only Truma E2400 and the instructions say you can use the heating only, without any water in the tank, we've not tried it, has anyone else?

[davenewellhome]

Not sure what instructions you're reading Minstrel as the E2400 is a 2.4 KW blown air space heater only, it doesn't do water heating.

I've just looked again and it's for the Eura Mobil Integra models. However ours is a C 3402 or C 6002 and says it is a hot air heater with an auxiliary water heating facility. HAs anyone tried heating without water in the tank? It would be good on the odd times we take the motorhome out for a day trip in the winter.

[davenewellhome]

Because the heat is not directly applied to the water tank it is quite possible to run the C series heater without water in them. If however you have the retro fitted heating collar it will not do anything as it is fitted to the outside of the water tank and will therefore do nothing.

Retro-fitting a 230V heating-collar to a Truma C-Series appliances has been discussed several times before on the forum, but, rather than link back to those earlier entries, it's probably better to refer to the following MotorHomeFacts forum thread as it's reasonably comprehensive:

 

http://www.motorhomefacts.com/ftopic-57276-days0-orderasc-0.html

 

As Dave advises, all variants of Truma C-3402, C-4002 and C-6002 appliances can safely be run as air-only heaters (ie. with their water tanks empty). However, the preceding C-3400 and C-6000 appliances must NEVER be run empty of water.

 

(I'm don't think this subject has been covered in MMM - at least not during the last 11 years - but I'm happy to be corrected.)

[Minstrel]

thanks for the info. How would I manage without the forum?

[Derek Uzzell]

Incidentally, I'm pretty sure that (a few years back) Eura Mobil Integra motorhomes had two separate Truma gas heating appliances as standard. A C-Series combination air-water appliance was the main heater, while a supplementary E-2400 provided hot air to the cab area and windscreen.
