here is one way of boasting the stock heater on a bug. i got this way out of a hot vws mag a year or so ago. all you need is 2 bilge blowers avalible for most boat places for about $50-65 each. you then cut the housing from under the back seat and make some adaptor rings to taper it down to the housings like such.

heres a comparison between the stock and the modified

bear in mind they are no longer than stock but are missing the tension that holds them together

Any idea what the power rating of the motor is? Are you hooking them up with a separate control switch the turn them up/down.

i think about 5 or 6 amp at the most. i had them hooked up to a switchunder the dash cause i never got around to a 4 speed resistor switch. they push a lot of air though on full bore though. warmed the whole car up in about 3 minutes

Great in you live in the colder cliamites of the US....

or melbourne also helps the demister

here they are in the car

Where can you get the blowers from?

whitworths ,bias or any of the boatding warehouses

currently planning to wire in a resistor switch so it can be set for different speeds

Wish I'd seen that about 7 years ago. Would have been brilliant. On the colder months my hands would quite literally freeze to the steering wheel. Hmm...I wonder if they would work better than the booster in the 1800/2L vans.

Hooked mine up to a battery-it can really move some air and reasonably quiet.Good find.

not a problem mate. i think they might only cause of the amount of air they move
