That is one of those products that make you wonder why it is not better known! I recall seeing lots of discussions in the past on various forums about rigging up something just like that truma unit but no mention of a ready-to-fit solution. Sounds very good.
I had a search after I asked the question and I actually saw them for £130 inc VAT (might be worth a quick search if buying?). Good value I think even at £150. The only thing which is a slight shame is that the element is 240V AC. Would be brilliant if it were (even as an option) to have a DC element as could use off-grid without needing to have an inverter.
Yes, agree - made me reluctantly think about gas again
Yes, but we find it a bit frustrating. We only need hot water once or maybe twice a day, but having to heat it means less energy goes into room heating when you want a quick blast. Overnight it’s good - you have a kind of storage heater under one of the seats.
With all respect Mark only the initial heating of the water takes a minimal amount of calories from the blown air process as the heating of the water is a secondary part of the operation, and once the water is up to heat all the calorific goes into the blown air side of it and the water unless you draw from the hot tap stays well above the 40 deg cut off point. I have to say that regardless of weather outside even in -0 conditions my van at least, gets far too cosy in a very short period of time to the point of having to lower the room thermostat setting, I have never had to use the boost setting other than occasional tests to make sure all is working.

Is this hot enough to ward off legionars disease?
40 deg is where you could be vulnerable to legionnaires, but the conditions for it have to be present in the first place, 60deg is safe. Phil
No offence at all! I'd wondered about our installation... if we do not have the hot water heating on, just the hot air, it takes ages (over an hour) for any significant water temperature to be reached. And certainly for the first 15-20 minutes (when you're at your coldest from being outside) our experience is that the blown air temp is a bit feeble. I talked to the dealer about this when we first had the van, and he just said the new installations weren't as good as old ones. Never got to the bottom of what he meant! We only have two or max 3 vents open as well, so it's not as if we're heating up the garage.With all respect Mark only the initial heating of the water takes a minimal amount of calories from the blown air process as the heating of the water is a secondary part of the operation, and once the water is up to heat all the calorific goes into the blown air side of it and the water unless you draw from the hot tap stays well above the 40 deg cut off point.

Have you checked the duct connections to the heater and made sure they are fully home as there can be a significant lose of pressure if they are not pushed fully home, I had a problem like that with two of my ducts, must have happened whilst I was delving around under the bed at some stage it looked as though everything was all up tight until one day my wife mentioned that the draft from the duct outlets were not as strong as they used to be. I found that it only needed one duct not to be connected properly to affect all the outlets and if yours is a 6 then it would be a lot worse, it would definitely be worth checking for a leak in the air system as on full blow mine would fly a kite.

Really? No, I haven’t checked so that’s a good shout. Especially as now I come to think of it, I did notice that shutting a couple of vents seemed to make little difference to the ones we sit near, which is consistent with a leak somewhere! Thank you! Why didn’t I think of that...
