Truma Ultraheat

Hi All,
With a thermostat tolerance of about 5 degrees, coming on at about +4 and going off at around +9or10 I reckon that is ideal, without wasting to much elecricity, unless anyone can tell me different.

Colder this evening than previously with external temperature just over -2° C and internal temperature in motorhome just over 2°C and when turned on heater has sprung into modest action whilst right down on the stop setting as Brian2 had recommended. We are now at one on this issue.

Hi Wearsider,
Glad to see that between us we have managed to put forward a constructive view, on what the settings should be as far as heat is concerned, the only possible complication now is humidity as Dutto has brought up.
I suppose we now have to put hygrometers inside to measure this and report to Dutto to find out whether we need a higher setting.

Murph... not sure what I'm doing wrong, been into my van this morning and the truma felt fairly warm to the touch, inside of the van was around +10 which is more than it needs to be really.. should I be turning it fully anti clockwise to 0? it's set on the 500w setting... without sitting in the van and monitoring the control panel temps not sure how cold it would need to get for the heating to kick in, seems like it's working harder than it needs to at the moment but I'm pretty sure here on the north norfolk coast we haven't gone below -0 yet

Hi CC,
From what Wearsider and I have discovered during the course of this thread, with constant monitoring and reporting with the temprature control set on the bottom stop when the temprature inside the van drops below +5 degrees the heater will come on. Then when the temprature rises to around +10degrees it will switch off, but because the heater takes some time to cool down the temprature will continue to rise to around 11 to 11.5 degrees. Then as the temprature fallls again it will stay off until the temp drops below +5, when the cycle will repeat, this is what happens in my van, and Wearsider (I believe his controls are similar to yours,) has come to the conclusion that his is similar though the tempratures may vary slightly

PS Your coment about the temprature being higher than expected is because of the 5 degree tolerance on the thermostat, Truma obviously consider this to be adequate, particularly as I would expect a smaller tolerance to be more expensive, and this temprature should keep the humidity down.

Brian,

Let's not get technical!

Wander in there with a whisky and chilled water. If there is any condensation on the glass then it probably needs a bit more ventilation.

Man wanders into the doctors complaining of a drip "down there". "We've had a lot of this since the AID's scare!" said the doctor. The man screams with fear! "Don't worry." said the doctor "It's only condomsation."

Best regards,

Ian

Hi All,
I have now fitted the windscreen cover and closed all the blinds for better insulation and the temprature is now rising to over +14 degrees before it starts to fall again and as CC says this does seem rather high, has anyone any idea as to whether using a small oil filled radiator as discussed last winter results in a cooler temprature. It would also be interesting to see which method is more economical on electricity, if anyone has one of those gadgets that measures electricity usage, and can give us some idea.
