So as the weather gets cold again, I realize that with my increasing age I need to do something about heat in the 914 if i want to drive it comfortably.

I'm running a header and most all the ducting on the car has been pulled out.

I've been researching all the threads on here about electric heaters and the Webasto heaters, etc.....I found this!

Thinking I can maybe mount inside or in place of the cowl airbox and run a couple hose into the cabin.

What y'all think?

Gary...
That's an interesting unit...
sort of a new Webasto heater.
Did you get one yet?
I think many here would be interested as to how it works out.
Maybe some how placed in the from trunk and the heater hose routed into the front ventilation box...
Here's hoping you get to ride in the warm again...
Good luck on the project...John

Why not get a modern Eberspächer unit that runs on gasoline?

I used to have one of those in my old VW Beetle. The car went from -20C to Sauna in about 15 minutes.

It can be used but I don't think like you said, it only has one outlet. Front trunk or maybe in the rear or engine bay then tapped into your heater channels (longs).
You would need a small tank for the diesel. You also have to cut a hole in the tub for an exhaust.

16"X 5"X 5-1/2" is a pretty small footprint. A lot smaller than an Espar bunk heater.
Price is damn good, looks like it must be china made though.

If you do go for it please write up a report on this.

I like the price compared to the Eberspächer. I am also thinking diesel will burn slower than gas; could be wrong. Less flammable?

It comes in a 2K and a 5K unit for almost the same price. A 5K blowing into a tee into the front openings could work. It would be great if I fit in the cowl....I don't have a washer bottle.

If it blows through the longs will it cool down? If hot enough this could work too.

Cool little thing comes with the tank...see in the picture? Looks like a whisky flask!

Either would be very interesting for non-air-cooled motor conversions.

A few feet of hose and heater core would be cheaper (IMG:style_emoticons/default/smile.gif)


I have an Eberspächer unit for my car, but as normal for me it is shoved away in a box someplace unknown.

This seems like it would be a slick option. You might even be able to get creative and stub it into the stock system as a replacement for heat exchangers, but using stock controls. And it would keep all the stink makers in the engine bay where they belong.

I purchased an old Eberspacher gas-fired heater to install in my conversion car. It could be done, but I eventually went with heat exchangers as I know they’ll bake you in a -6 if properly working. Now that they’re available through Porsche for the -6 (or some beautiful stainless ones through mb911), I don’t know if it’s worth the hassles of designing and installing a gas or diesel heater. Used SSIs are seen often enough for the -4s as well (though do need to be tested for cracks). There are photos of a system installed in the front trunk of a 914, but I’ve never heard of anyone that actually has seen one.

No matter what system you choose, be sure to keep a CO detector in the car as any leaks could kill you.

I know espar makes a diesel version for transport truck bunks, a D2 will fry you out of the bunk no problem. This looks like a copy of the D2.
Search "truck bunk heaters" or "espar D2".

Correct Mark my friend is fitting the diesel version in his boat,5kw unit which is generally fitted to motorhomes,something like .5 litre/hour consumption,he laughed @ the running cost compared to his 260hp main engine.
Personally I like this for a heating system and would be great to see someone get it setup and working in a 914.

Replace your header for a Tangerine header with heater boxes (IMG:style_emoticons/default/confused24.gif)

Been enjoying my car top down this week with a nice leather jacket and my regular SS heat exchangers. (IMG:style_emoticons/default/driving.gif)

Yes, I did google that before I asked the question. They don’t seem to have a dealer network in the U.S. so the question remains...

I had a friend that had a brother get killed in a motor home from a heater. Went to sleep and never woke up.
Family was never the same.
