does anyone know of a good 12volt plug in dashboard heater (for de-misting) i've bought one from a camping shop but it was rubbish. Any advice would be really helpfull.
cheers ritchie.

I don't think a good exists. I bought the just kampers one - it was very ineffective. Basically it is difficult to get enough power from a 12v socket to drive a fan heater methinks.

I have noticed this 12v / 150w heater for sale - but no notion if it is a good or bad idea in terms of performance and power drainage.

Here's another one from those super folks at Maplins.

Not sure how good it'll be though given the price: £7.49

Maplin Ceramic Heater

Mind you - at that price you could have a whole load of them around the interior!

I've got the one Tim mentioned from maplins, and to be honest,' her in doors' gives off more hot air ( I can say that coz she doesn't read this.......I hope!!)

I'm afraid it just isn't worth trying to heat your van from 12V.

For anyone not in the know, watts = volts x amps.

I'm not sure what the VW fuse is, but cig sockets are normally rated at 10A or possibly 15A if it's a top quality one. At 12V, 10A is only 120W - pretty pathetic for heating (think of small room heaters which are at least 1000W). Also the cig sockets tend to get hot at high currents (as can the under-dash wiring if it's not really up to the job) - I have melted them in the past just using a tyre inflator.

I have a small foldaway heater for mains hookup use that is 400W or 800W which is ok, but anything less isn't really going to do the job (800W at 12V is 67A!)

If mains hook up isn't an option you need to think about petrol or gas heaters which are unfortunately rather more expensive and tricky to install (needing to vent outside).

Really heated windscreen is the thing to rely on. In a perfect conversion, the converter in the UK should duct the heater (webasto in aircooled, water system on water cooled) through to the factory built vents in the dash - with a lever control to choose demist, or warm your feet. Cost cutting, or lack of design capability or whatever, Danbury seem just to dismantle the whole thing in a RHD conversion, and just leave you warming your feet with no demist option. The claim is that the heated windcreen will do the job...well kind of. Better maybe when the vehicle is cold, and a heater only blasts cold air, but not so good once a heater blower is going well, and keeping your side windows demisted too!

Don't forget this is because the RHD heater control mechanism is no longer available - it's not really Danbury's fault.

It could be fabricated though I expect

Dartmoor, you wrote

Irishman and myself have been thinking along these lines - trying to maintain some hot air to the side windows (and in my case to the windscreen too).

I'm liking OSG and Irishmans idea's on ducting heat from the floor mounted blower to the side vents. Thinking of making a triangular funnel to cover half the heater, out of plastic (possibly thin sofit board if it will take the heat) to feed the hose efficiantly.
Also i would be interested in any ideas on getting heat in the back when driving. Have looked at the boat/caravan heaters and they are pricey.

Just be careful everyone with whatever material you use to create your makeshift ducting. You wouldn't want to spoil the party by setting fire to the underside of your dash. affraid

I haven't seen an untouched Brazilian Bay but I suspect the ducting to choose demist or warm your feet wasn't actually there in the first place - presumably they don't need heaters in Brazil so there isn't one, and consequently much simpler ducting than we have become used to in modern cars in this country. It looks to me as though there were just the front flaps controlled by the now-missing slider control beside the speedometer, ducted straight to the windscreen slots and the side vents (the latter bing able to be individually controlled). No other flaps or controls in the system.

Who knows how well sealed the original front flaps were when shut, but very possibly not draught- or water- proof enough for our winters. Having just said that - do LHD Danbury-converted Brazilians still have their flaps operational?

I have one, LHD with no changes. The lever only opens the flaps and the airflow comes throught the vents on the dash, there is no other mechanism for deflecting the air to the feet.

for general ad-hoc heating (taking the edge off a cold morning/evening) anyone used one of these or recommend anything similar

How about a 12v travel hair dryer? You could mount it on some sort of swivel device - like those oscillating fan thingy's - and 'hey presto', your screen is clear once more.

lol!

I mounted a Maplin 12v ceramic heater on the side of the water heater so that Liz got a bit a warm air on her feet in winter (ah!). I plumbed in an extra socket under the dash (connected to the cigarette lighter circuit), but had to put in a 20A fuse to stop the circuit from blowing. For the short distance that the heater has to blow air (a couple of feet), it does fine, but considering the current draw it's pretty poor.

Kiteman gave me a demo of his wonderful heater upgrade at Vanfest, look elsewhere on the forum for his build details. He has successfully got hot air running to the screen vents. I'm seriously thinking of doing something similar (though less sophisticated myself).

I'd love to get a heater control working from the vertical slot in the dashboard - beam me up Scottie!

Quite agree regarding wiring. I traced it back to the fuse box and used high Amperage automotive cable to make the connections.

I'll be interested to see how people get on with those portable gas heaters. I too have looked at them. I guess you've just got to make sure that you've got plenty of ventilation! Shocked

From approx what date?

We picked up Tallulah in March this year and as with others, all of the ducting and controls has been stripped out.

The cab heater does a great job of warming the drivers legs but not a lot else, it woudl be graet to get some ducting put back in to spread it out a bit.

ok.

What happens (happenned) to all the stuff stripped out of vans up until now? I'm sure some of us without ducting coudl find a good use for it...

How about offering all the stuff that comes off the new builds that isn't required to Brazilian VW Bay.com members in return for donations to a chosen charity?

Can pre-2012 models be retrofitted?

It's great that everything now gets used and that new owners get vents that work etc, however there are lots of pre-2012 vans without these luxuries looking for a solution.

If you now know what bits are ne to make them work, maybe you could make them available to existing owners or at least point us in the right direction.
