jholland Posted October 19, 2011 Report Posted October 19, 2011 Bought a 4 door parts car to help figure out how the heck to put the 46 business coupe back together that I bought in pieces. Found heaters under each side of the front seat of the parts car when I got all the dirt and mouse you know what out of the way. Anyone know anything about these? No markings on either of them but they fit into the depresions in the floor pan like they were made for the car. Were they dealer ad on? Quote
greg g Posted October 19, 2011 Report Posted October 19, 2011 any patent numbers on them??? I know Studebakers use a similar system, and maybe Nash, probably seveal others also. Most mopars use a single unit model hung on the pass side inside firewall, or the dual heater system with one on each side. Later cars had a unit mounted to the radiator support, and using a plenum to feed the inside of the car. That said, heaters were still optional equipment, and there were several aftermarket suppliers. And folks think heated seats are something new. Can you put up some pictures of what you have? Quote
jholland Posted October 19, 2011 Author Report Posted October 19, 2011 no markings at all on either of them. I will get a photo of them and put it up tomorrow if I can. I cleaned the housing of one of them up already and had both checked out at radiator shop to be sure they held pressure. Not sure what to do with them but would like to know more. Thanks for the info. Quote
Vintage Metal Posted October 19, 2011 Report Posted October 19, 2011 floor heaters are great! I would use them if they are in good shape. My 51 Cadillac Coupe De Ville has them, and they work fantastic! There is almost 30 feet of 1" hose under the car just to get hot water to them.... I love little 'odd' things like these.... I would love to find a 46-48 Plymouth 2 door sedan and put a set in under the seat....maybe someday! Quote
Jim Yergin Posted October 19, 2011 Report Posted October 19, 2011 The double underseat heaters were an option on the Plymouths. Here is a picture from my 1936-1942 Mopar accessory parts list. I assume the same units were available 1946-1948. Jim Yergin underseat heater.pdf Quote

I assume the same units were available 1946-1948.Jim Yergin While I don't know for certain, but it wouldn't surprise me if some one retained them from their older Plymouth before buying a new P15 and installed them in their new P15. Having grown up on the frozen tundra, I can only imagine how precious some thing like that would be, and how much some one would want to keep that feature in their next car. Quote
jholland Posted October 21, 2011 Author Report Posted October 21, 2011 Looks very similar to the ones I have. Looks like the heater under the dash is part of it too. Mine has a heater but have not looked very close at it yet. How do you upload photos from your computer? I have some photos of the heaters before and after (cleaned one up already). Quote
jholland Posted October 21, 2011 Author Report Posted October 21, 2011 Maybe I figured out how to upload pictures on my own...not very likely but maybe. Here goes. Quote
Dodgeb4ya Posted October 21, 2011 Report Posted October 21, 2011 We have another winner of the very rare award! You have the very very hard to find MoPar factory under seat heaters models #40 and #41. They were an option in all 1946-8 Chrysler Corp. cars. Wish I had a set in my convertible! Quote
jholland Posted October 21, 2011 Author Report Posted October 21, 2011 What can you tell me about them? Were they just the heaters under the seat or were they matched with the heater under the dash (as in a set)? These came out of a 4 door parts car I bought that also has the other heater. Can't find anything on the internet. How hard to find are they? One of them cleaned up real nice and the metal looks good. The other housing will need some work (rust). Not sure how much work to put into it. Both of the heater cores hold pressuer and checked out fine at the radiator shop. Even more amazing the fan motors still run when you hook the up to battery.

Dodgeb4ya Posted October 21, 2011 Report Posted October 21, 2011 I have never seen a set in person! I have seen thousands of 1946-8 Mopars over the years at swap meets, tons of car shows and have never seen these under seat factory Mopar heaters- not even a NOS kit on Epay.. Have seen the GM under seat heaters in a lot of GM cars. I have no info on them-sorry I can't help.Maybe someone else has more info. Bob Quote
BobT-47P15 Posted October 21, 2011 Report Posted October 21, 2011 As I recall, that old P15 coupe we got parts off several months ago had an underseat heater. Thought I took a picture, but can't find one. That car had a regular heater also. Quote
jholland Posted October 22, 2011 Author Report Posted October 22, 2011 Thanks for the info. I will keep looking for some more information on them. I thought they were pretty cool but had know idea they would be this hard to find anything about. I do think they were made for these cars since the motor bumpout on the bottom of the heaters fit into depressions in the floor pan of the 4 door and the same depressions are in the business coup I am working on. Not sure what I will do with them. Still got a long way to go before I worry about how many heaters to install. Quote
RobertKB Posted October 22, 2011 Report Posted October 22, 2011 (edited) I live in the Great White North (aka Canada) and have never seen a pair of those in all the old Chryslers, Desotos, Dodges, and Plymouths I have seen. You would think that with our cold weather in the winter they would be more common than south of the border. My guess is that the under-the-dash heater put out lots of heat and the under-the-seat heaters were for those with very thin blood. I know my single dash heater in my Dodge D25 coupe is good for most cold weather as I have driven the car when the temp was 0 degrees Farenheit and colder. However, if you ever decide to sell them, I would love to have first choice on them. They would be a very interesting item to have and install. Edited October 22, 2011 by RobertKB Quote
jholland Posted October 22, 2011 Author Report Posted October 22, 2011 Ok. Not sure if I will use them or not but will let you know if I don't need them. Long way to go till I need to worry about any type of heater. Quote
