Electric space heater

Thank you - I'll check (by plugging into the garage & turning the gas bottle off!) but I'm sure you're right. A particularly bonkers icon to use in the context then...!

I shall also go back regarding the clock losing its time. When I mentioned it to the dealer before they told me it might be that the backup battery had run out or wasn't present. When I check, not only was there no backup battery, there was no space for a backup battery... it's not something I'm particularly bothered about as it's not a facility we're ever likely to use. But if it's a definite fault (and not just a design issue) I shall ask for it to be sorted...

Others have given you the correct answer....from the website...

Dual fuel blown air heating with Truma Combi 6 boiler (1.8kW electric/6kW gas/6.9kW combined)

in actual fact, the above combined figure is incorrect....when running in mixed II mode, it combines 4kw of gas with 1800w of electric to give 5.8kw total.

agreed, the use of a flame for heat used to be confused with the same symbol for gas....however Truma now use a gas bottle as the icon for gas fuel selected.

re the clock/timer...our 12v supply is maintained to the Truma with the engine on or off, the main control panel on or off, the Truma CP panel on or off.....

the only thing that will cut the supply is to turn off the main habitation isolator switch....so, as we don't do this, our clock is always right.

however, ours is a German van with electrics that don't get cut off for every reason going...it's left to the user to do this...

the timer is useful for turning on heating prior to returning to the van or, as we do in winter, set the hot water for (say) 6:30-7:00am and then, when it's hot, turn on the heating as I make the morning cuppa....the water will remain hot for the shower while warming the van...

edit...PS...

Be careful when generating error conditions (which you will do if running on gas with no gas...) some units (installations) can be a pain to return to error free....ours is fine but some are awful....my advice do the test the other way....select gas but have the gas bottle on...you should hear the boiler ignite with a few soft clicks, then a roar as the unit fires up and then a gentle flow of air, getting stronger after 2 or 3 mins. Ensure the temp is set up to 25+ and the fan set to HIGH. This will give you the quickest response from the unit.

good luck.

Right, fantastic response from everyone, many thanks :-)

Yes, I have just checked. On electric, with a handy plug-through meter, with the only load taken being the battery charger, it's taking about 1.5A. On EL1, with the heater & fan on, it's about 5A. On EL2, it's about 8.5A. All of which is what I would expect. And yes, the flame symbol is on.

"the use of a flame for heat used to be confused with the same symbol for gas....however Truma now use a gas bottle as the icon for gas fuel selected."

I would suggest that it's still being confused, since the flame is a fairly standard symbol everywhere for fire/flame/gas. Changing the gas icon to a bottle makes sense, but to be completely unambiguous they needed to have changed the "heating on" symbol as well!

Anyway, thanks again, all appears to be good - apart from the clock that is.

Our current motorhome, after a previous motorhome and a long line of caravans with Truma heater with manual controls, is the first one with the CP control panel. I found it did take a bit of getting used to. BB comments about the error codes struck home as I have caused a few of those!!! You will get used to it and I prefer the CP panel to the manual option now I seem to have mastered it!!!

Good news then?!

But a word of caution, take a small fan heater or similar ust in case there is a system failure, this can happen and at least you have back up. 

We always travel with a fan heater just in case, even in the good weather. 

Thankfully we have the same controls and heating system in the caravan and the MH.

I would echo this......have back up for as many systems as possible.

Our back ups include a fan heater, a good charger, a spare water pump, a spare toilet pump, fuses, bulbs, a cool box, and a comprehensive tool kit.

Yes, a fan heater is a good thing for back up....some Combis can be a bit temperamental...

One hint about 'errors' is that one of the most common ones is when, on leaving day, folk pull the EHU cable prior to turning the CP unit completely OFF.

This 'shouldn't' be an issue but in some installations it needs a reset on the unit, can be a logistical nightmare depending on where the unit is sited.

Try and get into the habit of turning the CP OFF when you've finished with it.

I see you have two 3.9,g bottles but the spec says the lockers are designed for twin 6kg bottles...is this a stopgap until the dealer gets you some correct sized units?

carrying just 7.8 kg of gas over two bottles (not refillable) means a lot of bottle swapping...

depending on your camping habits, this might be continual pain....

I am hoping that when our 6kg lites run out one has been on for over two years now. and am  now carry a full 6kg lite  in the car. both exchanged at the same time ,

We will be going for 3.9kg cylinders, on exchange next time to save weight and space,,

We have always carried a fan heater as back up ,,the much quieter upright with larger fan
