You have to have the heater on full for some time before you turn the fan on. Then you also need to check all of the toilet rolls used to create the blown air system. (That's my own description but I can hear folks in the know nodding). As you trundle your caravan over the hills and dales to your camp site they tend to come apart, so part of your set up arrangements on site should be to check to see if they are still joined together.
Then you have to remember that some of the toilet rolls go outside the van and then come back in and so, at this time of year, the heat in them is cooled down by the frosty night.
Tip - Warm up on gas and when you are toasty change to electric heating and turn it up high. Stick a tea towel over the vents under the front cabinet - they blow cold air in and make the hot air rise, so you sit in cold and then stand up and find it really warm around the head!
Round about bedtime with the heat on high all night and no fan its lovely...but then its bed time.
Blown air system is there for the purpose of annoyance. Once you understand that you can live with it!!!
Phil (Just back from Chatsworth arguing with the blown air system for a week - "Look you're supposed to keep me warm"....go outside and get a large branch and look at the heater and say "Right...you've asked for this" and then belt six shades of something out of the Truma)

to get hot air quick use gas and electric at the same time and then turn one off.if the fan does not work contact gary arc systems who sells spares.or can tell you how to check it. http://www.arcsystems.biz
------------- the only silly question is the one you do not ask.
There are a few reasons why the fan does not work, first are, no 12v getting to connections on back of fan housing, dirty or poor connections of wiring loom between fan and control switch.
Otherwise, faulty switch and/or the little circuit board inside fan housing, lastly fan motor brushes worn out.
Cwdc, I recognise most of what your saying and indeed nod in agreement, however it's agreeing with your misconceptions of the blown air heating system, not that its actually designed to annoy you...you blame the van manufacturer for that!
Take the large floor vents your covering? block them off permanently there not needed, also look under the sink you'll find another one over the wheel arch letting cold air from the fridge vent inside?
Also why do you say to run the heating before using fan?
Take electric heating, this uses exactly the same elements as in a kettle, do you switch your kettle on before adding water?
Of course not and neither is it required with blown air!
There's load more but what I don't recognise is this problem with your toilet rolls falling apart. that's a new one? have you had your vans wheels balanced?!
Also why do you say to run the heating before using fan?
Read a number of posts in various threads on the heating system where other posters recommend it. Have to say that it does seems to operate better if left to heat up first before fanning the hot air around.
with your toilet rolls falling apart. that's a new one? have you had your vans wheels balanced?!
Yes and the brand new van next to us at Chatsworth had the same problem. They slot into the corner connectors rather than being stuck in and just seem to come apart. I always go round and check that they are all attached as part of the van set up these days.
Read quite a number of comments on various threads about the blown air system not being overly promising. You happen to notice it more on frosty nights.

So you have 'corner connectors' rather than the ducting itself being bent around the corner? two things here, if their falling apart, use one or two upholstery tacks to hold them in place.
Very poor design though because the other problem is how a tight elbow will slow the air flow? this is equivalent to the resistance an extra 600mm (2ft) of duct gives for each elbow in the system.
A swept bend in the hose on the other hand adds little if any extra resistance and in your case would improve throughput and therefore outlet temperatures.
As for the fan timing, yes you have read it many times but not from me because it's all in the head? It simply cannot make any difference as the elements heat up in seconds, fan on or not!
Like I said it's exactly the same as a kettle, the heat produced is transmitted to all parts of the van instead of coming just from the fire. If you leave the fan off the air temperature has already risen by the time you allow, so the output from the vents appears warmer, same air though!
Putting the fan on 'Auto' will keep the speed down and overall the 'whole' van will warm up quicker
And as for not a good system, equally wrong, only it's installation is at fault.
This is where all the bad press comes from, sort out installation problems and the heating will prove itself more than adequate
