I'm curious if anyone here has ever put some sort of electric heater into their 914. 914-6 heat exchangers, or equivalent, are $1500+. A header can be had for $400 and increases performance. (IMG:style_emoticons/default/biggrin.gif) I can live without heat per se, but I will really need a defog option in my car for rainy days. Anyone rigged something up? Care to share?

Chuck,
I have heard of but never seen anyone do the VW gas heater thing... Some headers do come with heat exchanger for 4 cylinders. Not sure about sixes. If you really are just looking for a good functional street car, you can go with SSI heat exchangers instead of headers. Great performance and great heat. In Minnesota you would need at the least a defroster as the windows go fog city with the slightest touch of rain combined with closed windows and breathing occupants.

A really big Jacket (IMG:style_emoticons/default/biggrin.gif) I just use the rain-x no fog on the inside and rain-x on the outside. I have yet had a problem with it fogging up on me. I have no heat or blower motor anymore. It doesnt get as cold here as it does there though. I don't really drive it in the pouring rain either.

Chuck. My daily driver is a smart car - super efficient little diesel but so little waste heat that it is pretty cold in the winter. They have a little electric heater that cuts in as a booster but it really doesn't do a lot. Might take the mist off the windscreen on a cool day but I wouldn't hold out a lot of hope for it.

There was a gas heater available on the original bugs that would probably be a better answer. Mind you they had a bad rep for fires.

I seem to remember the guys on the smart forum talking about an auxilary heater from across the pond. I'll do a search and see what I can find.

Why would that be bad (IMG:style_emoticons/default/blink.gif) (IMG:style_emoticons/default/poke.gif)

It could be interesting to hear about the other heaters though.

Put two 12 volt hair blow dryers in the front trunk, duct taped to your defroster vents. (IMG:style_emoticons/default/biggrin.gif)

Eberspacher.

Check both the Samba and your FLVWPs (That's friendly local VW Parts)

A rebuilt unit can be had for 450 here in Colorado in the summer. I assume demand goes up in the winter-> prices up.

Seems like JC Whitney used to offer a gas heater sytem for bugs. Don't know if they are still in business?

The Corvair also had a reliable gas heater that may be available for less.

That is EXACTLY what I am trying to avoid. I may just need to bite the bullet and spend the $$ on the SSIs.

After the day I've had, that sounds like a helluva good idea. Simple, effective, inexpensive.

I am from MN. and when visiting my family one winter, had the heater core in my camaro fail. 55 mph in 20 below weather. Imho there is no way a couple of hair dryers would get the job done. Although, with this global warming I could be wrong. (IMG:style_emoticons/default/screwy.gif)

When it gets that cold,your 914 should be parked - heat or no heat! Use your beater, and save the 914 for nicer days.

You misunderstand. My car will only be taken out once the salt is off the roads in the spring and will be put away by November. But, I would still like to be able to drive it on rainy days and around here, that means defrost.

I know that they make small square space heaters that sit under a desk and plug into the wall. I have seen many in offices where the desk jockey gets cold.

You may be able to power one of those with an inverter to warm up the cabin.

Where does the defroster air get returned to the blower? Duct the heater there and you would get heat out of the defrost vents.

JC Whitney (yes they are still in business) used to sell a 12v heater that was essentially a hair drier mounted in a different plastic case and could be used as a defroster. They were ugly and bulky, but with a creative mind and some work, I'm sure it could be modified to provide heat to the blower plenum.

I think in the end, it may be easier to simply put a box around a set of headers and blow air through the box. That is the basic concept of the stock heat exchangers.

Good luck with your project.

No electric heater will work effectively, the alternator cannot supply enough power!
SSI heater boxes along with a functional stock heating system both works effectively and is cost effective with all alternatives I know about.
