Faults with Truma heaters

Has any member found that the new combined water/hot air heater is usless at its job?  We have spent 4 days in cold weather on a cl site, we get the Lunar twix axle warm and then had a shower. The water in the heater  is now cold fresh water and needs heating,
so whilst it is heating we get no blown air heating! So the caracan goes cold . We then start the procedure again, heat the carzvan, have a shower, van gets cold again. I find this a serious failure in what is meant to be an all weather heater.  

Our answer was to but a 1 kw electric heater to heat the caravan whilst the expensive pile of junk in the corner of the caravan heats the water again.

I suppose we were lucky that there was only two of us in the caravan imagine the time wasted sitting in a cold van if there had been 4. I spoke to Truma but it was a waste of time, do these people acutually have caravans and if so do they use one in cold
weather!

    I assume you're referring to the Truma 4 type unit that can run on either electric, gas or both? Even on the highest electric setting (1.8kW) it may struggle to heat your 'van comfortably in the winter. If you need more hot water and warm air the solution is to switch to both fuels (gas and electric) at the same time. The units are designed to run this way. It may not be ideal in the winter but the limiting factor is normally the site hook up supply which is 16 amps maximum, unlike your house where you have up to 100amps at 230Volts.

    I agree the system works best on a mix of gass and electricity in cold weather. Not sure if the system is up to a twin axle as our Quasar 564 feels to be near its limit.

    We had problems with our Truma Combi 4E  until we worked out that the temperature sensor was too near to a local heat source(TV in this case) so we rewired it to near the habitation door.It now functions perfectly well throughout the range of the control
    settings.The sensor needs to be as close as is possible to the coldest spot in the van in order to achieve optimum performance of the 4E unit.Hope that this helps,Ken.
