Never leave a campsite with your clothes line tied to a lamp post.
I know this is a well known phenomenon but despite searching the "Resource" section I am unable to find a definitive answer. Our problem is when we are parked up with the hab heating on there is a noticeable draught coming into the vehicle from the footwell area. There are vents in the doors which we have blocked off with tape so they are not the culprit. Setting the heating to re-circulation as opposed to outside air seems to have no effect. I'm about to do a "smoke test" to see if I can locate the source of the cold air, but I welcome any input from a Funster who has managed to solve this problem,

I seem to remember people mentioning the seat belt strap housings being the source of cold air coming into the van?

Thanks for the suggestion, but our seat belts are mounted on the seats themselves. I should have added to my OP that the vehicle is a 2007 Autosleeper Nuevo mounted on a Peugeot Boxer chassis,

A fleece blanket over the dash down to the floor works...(y)
Underneath the blanket would make a great place to put things you wish to keep a little cooler .... choccy bars for example.

I'm sure someone on here mentioned a vent under the van, under the passenger seat. Not had chance to look at mine yet.

Where do you think the draught is coming from? floor level or higher at dashboard?
The reason I ask is that many have fitted carpets in the cab at floor level, some manufacturers even offer a set of insulated mats as an optional extra!
Have you tried hanging say a large dustsheet/blanket over the dashboard letting it trail on the floor to see if the draught is from the dashboard region.
Have you fitted windscreen/side window external covers like Silver Screens to aid in keeping the heat in the van?
Apologies if you have already tried some of my suggestions, but they are a good place to start.
PS: as for the smoke test, I'll join you outside for a fag:wink:

Would be interested in the results from a smoke test..
I have blocked all the holes I can find yet the draft is as strong as ever !

Our 2014 Majestic has the Peugeot cab and they've fitted curtains that go around the seats sealing off the rest of the cab area. This helps to defeat any draughts coming from the blower vents and elsewhere. An outside fitting silver screen is also a must for us in Winter.

Well that`s our 12th year & still loving it.
Under the van passenger side door in the chassis inboard side is a bellows valve, about 100mm x 100mm, the one on the drivers side is blocked off re the exhaust passes right past it.
You can cut a piece of plastic or buy a Fiat cover to blank this off, also remember to shut all inlet vents on the dash.
Ducato cabs are very draughty places, check the floor behind the seats were the cab connects to the habitation pod, I have seen a gap along there.

long curtains down to flour level and on a runner that go's right round the cab works for us you will find almost all vans have the same problem first thing I do is fit a curtain rail that runs around the windscreen and round the doors

many many years! since I was a kid
a roll of white duct tape is your friend. air comes in from vents under the seats, vents in the cab doors, through the standard seat belt mounts (they are open box section under the van) and also through the dashboard vent

Yes. When we got our van Jill replaced the curtains with floor length ones. She also sewed Velcro buttons to them so they can be kept closed.

This is what they look like on a 2013 Fiat Ducato. In situ, outside (removed) and inside (removed).

I have:
Replaced the bellows vents with solid inserts
Blocked off the door vents
Fitted curtains from floor to ceiling
Filled other potential sources with expanding foam
The heater is always set to recirculate when we park up

We still get a gale force wind from somewhere !
It is strong enough to blow the ( heavy ! ) curtains about...

Ducatos are made for builders with big boots , gloves and coats. Not for softy motorhomers. Seriously though our 2005 Ducato was very draughty and I never did track the drafts down.

We have the Autotrail Apache and I found the best way to stop the draughts getting into the Habitation lounge was to have a removable wall, so I fastened some "U" channel to the side of the the unite and cut 3 pieces of Ply, the bottom section stays in all the time to stop the dog coming forward whilst driving, we slot the other two sections in place at night, pull the bed across and presto van as warm as toast, plus we never get any condensation on the cab windows.

Agree but still a different van base so maybe a different solution.
I mean the van base is practically the same being built on the same production line....not the conversion.

Fiat Ducato, Peugeot Boxer and Citroen Jumper...... All. SEVEL vans built in the SEVEL SUD factory.

Not so The cab units are identical apart from the badges, as the draughts are coming from the Sevel base unit the cure is the same for all.

I found that the Draught was coming from behind the Speakers fitted in the doors, whoever had fitted them had had to penetrate the film plastic behind the trim to make them fit. I put some small foam cereal bowls in the openings and sealed it with mastic. that cut it right out, now I have a Merc; "A" class the draughts come from a different place!:rolleyes:

My wife has made a quilted skirt that clips to the little shelves at the bottom of the dash, cuts the draughts substanially.

Many thanks to all of you who have taken the time to offer suggestions. I will try and bring this thread to a conclusion with the story so far. The "smoke test" came up with interesting results so if any of you want to have a go then this is how I did it. I tried several different smoke sources but the best one was a doubled up sheet of kitchen roll twisted as tight as it would go. Once lit and blown out it continued to smoulder (and stink) with the occasional puff on the end to keep it going. In use there were VERY small draughts coming from multiple sources and the whole exercise was inconclusive until the curtains were drawn which had the effect of funnelling all these small draughts into a clearly visible one in the gap between the bottom of the curtains and the floor.
So we feel the best solution is to either extend the curtains or block off the gap as several of you have suggested. Also silver screens would stop the build up of cold air against the glass which then sinks to the floor to add to the problem.

Setting the heating to re-circulation as opposed to outside air seems to have no effect.

If it is a fan assisted heater with enough capacity both in air volume and heating capacity put it onto fresh air. It might cost you a little more to run but any air movement would be going out. It should stop or at least reduce any draught.
