truma ultra heat

Only just joined forum away at mo in our bessacarr E495 motorhome and running the heater on mains electric but seems to be either boiling or nothing. Tried moving thermostat to reduce heat to no avail and blowers on to disperse heat. Dodgy thermostat or am I doing something wrong. Please help! !

Welcome to the forum ! You seem to have made your first post a a very quiet time when hardly anyone is around. It's not normally like this...

Apart from using a Truma heater I know nothing about the inner workings of them but is there any chance that your heater is also running on gas as well as electricity ? They are designed to do this and produce an immense amount of heat when they do so. Electricity alone is OK for keeping the place reasonably warm but would not normally give such a high air temperature.

Just a thought...I'm sure someone will be along soon.

Please clarify, is it the water heater or the habitation heating? My guess is you mean water heating (you use the term boiling)

If it IS. actually boiling then my bet would be that the thermostat in the water heater is knackered as it should cut off the power before the water gets THAT hot. Replacement is Not a DIY job!

Its not the destination that matters.

It's who you share the journey with (even if like me, itís in a caravan!)
I am very fortunate to have Mrs Plodd to share mine with

I hope it is not as serious as mr plod says, but could be. If it is the heating you are having problems with, is the thermostat for the heating covered up? I have known people having problems only to find that the thermostat is covered by a blanket or something.

For your future reference, here is a good 'idiots guide' (not you, all of us) to the workings of the heater controls. Keep it handy and use it all the time.

Good luck.

The water heater is called Ultrastor and the room heater is the Ultraheat. As the OP mentioned putting fan blower on and opening vents, I assume they are talking room heater. On the thermostat you should be able to select 500w, 1000w or 2000w , have you tried it on a lower wattage setting?
