Cheers think I'll get one fitted.

Odd. I have a fan fitted as it was a drugs van. rear heater, rear aircon.
Every morning its all wet. The fan makes it vented

[johnny bravo]

Did you fit it yourself or take it to a workshop

[mikey]

i fitted it myself  there is a bit of moisture  on the roof now the temp dropped  but no drips  i drilled 5 pilot holes   and ten used a jigsaw with a wood dlade on it  yes a wood blade   cut straight through   here is the tutorial i watched https://www.youtube.com/watch?v=09Gpu96ffKo

[johnny bravo]

yes i looked at this video,   seems straight forward,    i will be looking at getting one installed,  moisture is bad this time of year
ill look out for a hole saw.     nice clean cut. ive never thought about this but will now, if not for now for next year deffo.

carefull with the hole saw  i bought one didnt cut through   then i realised  it was a wood  hole saw    hence  the electric jigsaw  used

A dehumidifier works perfectly in our vans.  Any dampness from the working day is gone for the next day. I also have noticed that with the lack of dampness, the van equipment is slower to reach freezing point, although heaters are on frost stat, but rarely kick in.
One the best bits of equipment for keeping us going through winter months.

Just my pennies worth.....

That's a good point. It needs to be able to cut steel. I big one isn't cheap either.

looks straight forward on youtube  or the Flettner website,    around £70 for theres,  good straight forward video. diy .  or biy,   bust it yourself   as i probably would.        id probably get more water coming in by doing it myself.      you would have to get it right.

My missus karcher window vac works a treat 

[dazmond]

to me my van is just a work van.im not bothered by a bit of water/moisture.its inevitable when wfp.having the heaters on full blast driving to and from work(and lunchtime in winter)helps.

For those that already have vents on the roof of their vans and have a full bulkhead, do the vents completely prevent water/condensation on the inside of the vans roof?

[mikey]

well i thought mine did   untill  the temp dropped   to 0 minus    so looking back i used to have 100s of droplets  ready to fall but they have gone  now  i have a layer  of moisture  which i can write my name in   but no droplets  i dont know maybe its stopped 50%   to 60 %     but i dont have a solid bulk head   i have strong bars and mesh               i think  there better  for animal   transportation    dont get me wrong  its worked for me

No

I'd be surprised if an air vent got rid of all (if any to be honest) the moisture in the back of the van, you'd need an extractor fan type gizmo or dehumidifier as someone above has mentioned

Theres no air circulation when your van is stationary, and the van roof is always going to be colder than the air inside due to it being metal and conducting the temperature outside

[colin bird]

I have a transit custom with fixed bulk head,I get quite a bit of moisture on roof,my previous van was an expert no fixed bulk head due to this van would dry out during the day with heater on and window open a bit.
Dehumidifier is the way to go ,as others have said,or a  2kw heater on all night but that would be costly,,
