I'm not sure my truma boiler is working properly. In use I notice that the flu gets very hot as does the flu gases. These seem to be far hotter than the warm air coming from the vents inside the motohome. It seems to be very inefficient to me. The motorhome is brand new and obviously I have not used the heating in winter but I have doubts about whether it would cope. Has anyone experienced this or is it my imagination. I've run it flat out on a mild night with the thermostat set at max and it should be sweltering but it isn't. If I set it to combined heat and electric then you do get a hot blast!! Your views would be appreciated.
I have the same boiler as you describe. I am currently on electrical operation only at 1800 watts and all is well. I have been running the heating on the thermostat 24/7 since I collected the van last week.
The boiler is located towards the rear of the motorhome and has six outlets - one in the garage, one in the loo and four in the main hab area.
It does get a lot hotter on gas only or gas and electric together, but even on Tuesday and Wednesday night when it was quite cold outside - and I had no external screen covers on - the motorhome was very snug indeed.
I know it sounds silly, but are you definitely on the 1800 watt setting and not the 900 setting?
Regards
Russell

Yes, it's set to max power. I don't get much of an air flow from the vents even on gas it doesn't seem to shift that much air but on electric only it's pathetic. What's yours like?
If you put it on gas and set the termostat to the hottest setting it will take a few minutes to warm up and then the fan speed gets faster and you will be too hot very quick. In mine it sounds like a 747 on take of when it is on full until the van warms through.
Are you sure you have left it long enough to give full heat? On electric it is no where near as hot, but warm enough on the No2 setting most of the time.
yes it does sound like a 747 on gas - good description but I don't get the expected blast from vents even on gas. If you really want to warm/burn your fingers you need to hold them over the flu - now thats hot. With it set to electric I managed to get an increase in the internal temp of about 2 degrees in 2 hours with an external temp of about 14C. On electric the barely warm air only just makes it out of the vents I'm beginging to think that one of the electric heating elements has gone west
2 degrees in 2 hours? Not what I'd expect. Our Coral, 23' long, look at the avatar, warms up so quickly, even on electric 900W.
If it were my problem, I'd be wanting it checked. But please remember that fan speeds are controlled automatically, unlike predecessors with fixed speed. When my fan cuts in at 747 speed, it would burn the fingers!! then it settles to a quiet hum. Isn't that the idea?
Good luck with finding a solution.

Had the offending boiler checked out today and yes it is working fine. Basically I was told to stick to gas as these boilers were not good on electric for heating purposes - though fine for hot water. So I'll stick with my little fan heater if I'm on electric hook up. This boiler seems to me to be a step backwards in efficiency terms - so much for progress and innovation
Another member phoned me recently re his boiler - it turned out the thermostat was removed and refitted in a different location within the van.
I cannot understand how the new type of boiler can be better or worse than the previous one, given the power is still 1800 watts on electric.
I am currently using a new Truma E and at present all is well. The amount of hot air on electric only does seem less at some outlets than in the previous van (C 6002 EH model boiler), but the boiler is located to the rear of the motorhome, whereas in the previous van, the boiler was more central.
Keep us posted though and I will do the same.

hi all,
yes as Russell said i had some issues with my boiler which was all checked and said to be working fine, on further investigation they discovered that the panel that the thermostat was fitted into had a heating pipe running under the false floor, and therefore giving a false reading, the thermostat has now been re sited elsewhere and the heating is working fab
I also suffered poor heating from this model. Eventually I returned to Truma at Foston in Derbyshire.
On initial inspection the location of the thermostat was considered to be the problem. However after about an hours wait in their imaculate staff restaurant, I was recalled to the worshop and asked to enter my M/H, it could only be described as "like a sauna" The displayed temp on the control panel showed 29c, and an independant digital therm sitting on a seat back showed 30c.
The problem turned out to be the ducting never having been connected to the base of the boiler, consequently heat poured freely into the cupboard housing the boiler, and tripping the thermostat that was sited in the side wall of the same cupboard.
This may or may not be your problem, but a visit to Truma may solve your difficulties
