There was a similar question on a couple of other forums a few weeks ago and it turned out that a circuit board had gone. Unless you have the skills to work on heating appliances it's probably best to get it checked out professionally.
hi,thankyou. i have just had it checked by the dealer i bought it from. they say it should operate like that.i think they are misleading me so they dont have to fix it. might be wrong though.
Hi Bernnie - maybe worth a phone call to Truma themselves, alternatively select your heater type on their website & there are some general Q&A at the bottom of the page.

Sounds like it could be working OK.
the Combi can only put out what it gets in, the fan speed is dependent on the amount of heat in the unit that it is trying to dissipate.
on electric, you will have only 900 or 1800w (depending on the setting) whereas on gas you will be using upto 4000w on a Combi 4 or 6000w on a Combi 6, so a significant difference. Basically this is the reason for the difference in the fan speeds. If the fan spun fast with little heat generation behind it, the fan would be trying to blow the air out before it had got warm....so blowing cool air rather than hot.
