I have had ongoing issues with my Truma E2400 gas heater not igniting. Installed in 2013, but it has had little use.
Covid has meant the last 2 years or so has delayed my ability to have an approved Truma agent find the cause. In recent days I have found that the probable cause has been severe internal corrosion affecting large areas of the furnace body and wiring connections etc. One of the corroded wires/terminal inside the unit actually fell apart when touched by the agent. The state of the corrosion was such that it was considered that repairs were not appropriate. Other areas such as the fan body were not corroded at all.
The heater was scrap value and was removed. My heater effectively lasted for 3 trips, when visiting outback Queensland during SAs miserable winters.
I believe that the corrosion is the result of condensation. Particularly given that those areas that run cold are not corroded at all.
I would like comment from members who may have similar experience. Others may have a similar experience.
Probably useless info. We run it (needed or not) everytime we use the van. Happy so far. Our van use has been intermittent so far. We do same with everything in van.
Just a thought , could it have been electrolysis? Not moisture.
In the fan pic is that orange colour been rusty water from condensation? Cast aluminum corodes like that in the first picture from condensation. See what hapens under the bonnet of a vehicle thats been covered totaly with a polly tarp out side. Every bit of cast aluminun will be coroded like that.
The orange stain is rusty water that has evaporated I think. I am assuming the water (condensation ?) has dripped off the rusting furnace components and has been accumulating in the bottom of the heater body, and has then evaporated.
I have written to Truma in Germany for a comment. The corrosion is more than just surface corrosion however and has affected wiring/terminals that also were affected. When touched the wiring fell away from the terminal block due to it corroding away.
