Trumatic Heater (think it's Ultraheat)?

[StitchUp]

Now I'm retired I have some time to get to know our motorhome and it's installations and get them working as they should
Last week I got to know our Truma water heater and had it working on both gas & hook-up. I've now moved on to the Trumatic Heater - I don't know what model it is!

I have it working on gas and figured out the way to switch on, ignite and get the blower working. However, I've no idea what these controls do;

I presently have the gas turned off at the cylinder and the settings as in the picture, but, there's no sign of any heat (I'm presently on hook-up at home) Should I expect heat from these setting? Thermostat turned to 20.

Thank you

I would turn the thermostat up to 20 and see if it kicks in

As shown on left hand switch three power level settings right hand switch on/off. Rotary dial is temp setting you have it on 7.5 C so probably not put out any heat. If you turn it up to 30 c you should get some out put. The reason for the 500w, 1000w 2000w setting is to enable to use the heater when lower amps are available such as European camp sites. And the switch to the right is the hot water from the mains switch red being on. I am not stating the obvious just how it all works.

Just realised that and ran out and turned it up!

I didn't realise these controls had anything to do with water as I have another set of controls on the other side of the van controlling hot water! If I switch the illuminated red switch off, the thermostat green light also goes off.

Could do with a manual - if I knew what model I have I'm sure I could find one

Now working thanks. Was sure I'd tried before!

Thanks for all the support passed & present I don't think I have any more questions for the time being.

My mistake someone has put in an extra switch to isolate the heater, but it is the same type of switch often found in older motorhomes to control the water heater.

The van is 23 years old so I guess the original fittings/installations are likewise - old too
It's nice at last, to have the time to methodically go through everything rather than be 'harnessed' to a busy work life, on-call 24/7 too for an emergency service

S3002 at a guess

Yes. Though mine doesn’t have the electric heating element.
Does the OP’s have a heating element inside or are the controls for a separate “bit”?
I’ve an ultra heat installation manual but not an operational one.

It would appear to have an electric integrated heating element although not apparent when the cover is removed.

The electric element was an optional extra according to my truma booklet, the element kit is still available to buy but it's a big faff to fit and not cheap

Here's am operational manual I mean video:

This a photo of a dismantled one. You can see the twin electric elements.
On your original photo the right hand control is the 230v on off switch for the heating elements and incorporates a 230v 13amp fuse which is the same as found in a household 3pin plug.
The left hand control is the power outlet selector 500/1000/2000 watts and the central dial is the thermostat for the electric element heating.
The fan which circulates the hot air from either gas or electric source is powered by 12v and has a separate control on the top right of the heater casing.

Thanks all, the controls on my installation are different to those shown in the picture posted by kevenh but have the same effect.
Itsmcb those picture are a great help, thanks It seems mine is fully working both on either gas or electric.

I wonder if a portable fan heater would be more efficient than using the Truma i.e. 1Kw on a portable fan heater producing more heat than 1Kw on the Truma?

truama usually just add an e to the end of the model number to signify an electric element is fitted

It will produce exactly the same amount of heat, the only difference will be distribution.

A fan heater will blow heat to wherever you point it, you will know better than me how your Truma distributes heat.

If you are pessimistic, then a fan heater would be a good idea instead of using the truma on electric if using on the driveway or similar. reason for saying that is a replacement element for the Truma is in the hundreds. a new fan heater is around £15. So reducing the use of the element would not hurt.
