Hi,
New to the forum, but have some questions coming up in regards to Our bolt/nut restoration / rebuild.
We're wondering if anyone have experience With installing a electrical heating system instead of the original ?

Welcome to the forum, Kaw.
I have no experience with electric heating that you ask about.
However, as an engineer, I have to ask why you would want to do that? The stock system uses heat that has to be taken out of the engine anyway.
Electric heat would be very inefficient, also add complexity and weight.
It could be done, I suppose. I just see little to no benefit.

Kaw,
Are you referring to an electronic heater control valve?

Electric resistance heating would probably consume 70 to 100 amps from the electrical system.
500 watts (1,706 BTU) / 14 volts = 35.7 amps
1,000 watts (3,412 BTU) / 14 volts = 71.4 amps
1.200 watts (4,095 BTU) / 14 volts = 85.7 amps
1,500 watts (5,118 BTU) / 14 volts = 107.1 amps

1.200 watts (4,095 BTU) / 14 volts = 85.7 amps
1,500 watts (5,118 BTU) / 14 volts = 107.1 amps

Yep, just what I was thinking. I don't think the stock alternator would hack it
Plus 1500 Watts is a typical hair dryer. I can't imagine that heating the car too well on a chilly day, let alone truly cold one.
Maybe no heater at all? My Pantera is a California car where previous owner took heater out. I considered installing heater, but while driving it in 0C temperatures, the engine in the back and the coolant pipes below kept me nice and warm. I only need heat to keep windshield defogged in certain rare conditions. Just my $0.02
or use heat from the exhaust as on air cooled engines ? ( Porsche 911...)
a bit casing around part of the headers, a little fan and duct to the interior ?

Thanks for all the posts
A little bit envy on those who can drive such a car on a daily basis vs. the weather here in Norway. But then again, I somewhat appreciate the Seasons...
That leading to that we usually just have such cars out and running in weather conditions (Seasons) that permit it.
Have understood that the heat from the engine bay is to be reconed with (toying with some solutions here...), but the most irritating problem for us here in Norway is the moisture due to that it rains quite often. So, as we see it, we need something to keep the windshield defogged (as Mikael from Denmark points out).
OK, we'll take the different posts into condsideration, before we do something stupid...
Liked the "vitality" of the Forum !!

Hi Kaw, to install electric Heater would be a bit like crossing the River to find Water ;-) When I got my Pantera the Heater and A/C was a mess. Most of it was missing. I had a friend in US help me to find a used Condenser scroud with Fan which I installed etc. But that is a diffent story. The Heating system is really simple incl. the Heater valve. It is easily replaced with an after marked or even to rebuild it is just replacing the O-ring ;-) the challenge is to get the cable to work smooth so that the valve can close fully. To bring the system up and running would be much less effort that converting to electric. You have a massive source of heat just behind the firewall ;-)
I decided to drop the A?C since I never use it. The weight savings of everything removed was about 100lbs. I made a box with electric motor and servos to control several things.
I have a circuit driving a mixing solution slightly different then conventional controls. For instance I can control the vent and floor in any mix combination. The Defog is completely separate. The fresh air or recirc is completely mixable.
I made a P2 T2 valve for the cooling tubes so no pump is needed. I use an electric valve to turn on the heat. No I don't recommend someone going through all of this but it is an example:

Hi again,
forgot to mension in my 1st post that we in our rebuild going to (don't read this "purists"
) try to clean it up a little bit, and get rid of some of the tubes and hoses, along with the A/C and some other bits and parts.
comp2; Your solution is to high-tech for my IQ, but loved Your gauges and alu. We're planning on something similar; with a alu dash and some Upgrade on the switches, etc. Pretty sure You've been fiddling With some electrical solutions too
, and that have we also some plans on, but that I have to make another post on.

good idea for extra Amps
What option did you end up going with? If you’re still in need of any assistance, I’d definitely recommend checking out a Sacramento heating system repair company like https://alphamechanicals.com/heating-repair/. These guys have helped me out a couple of times with my own heating issues, and I’ve been really impressed with their work every time. They’re quick to respond, thorough in their repairs, and always explain what’s going on in a way that makes sense, which I really appreciate.
I’m originally from Germany and I had a 1974 Porsche Carrera as my daily driver..The heater I had was a gasoline powered unit from Webasto pretty much like what is shown in the pic… fantastic unit, set timer and get in a warm and defrosted car….
if I would live in Norway… This would be what I would do‼️‼️

Have you considered nuclear for the heat source?

I think the shut down procedures are rather long…. But the automotive model “Chernobyl 5000” is cheap..
Tap the brakes… this thread was from 2014…
OMG
LeMans…. You (re-) started it!!!
