Technical Under Dash Heaters

Discussion in 'Traditional Hot Rods' started by spillaneswillys, Nov 4, 2018.

  1. I am wanting to put an under dash heater in my 34 Dodge for driving on the decent winter days Speedway has a few different ones and j am just w/o daring if you guys have had any good or bad luck with these I expensive heaters. Not looking for a Vintage Air or anything like that.

    Roberts Motor Parts sells a 12V heater that resembles a vintage heater....

    I don't, I called them a few months back and they told me that it resembles the old square under dash heaters. Perhaps you can call them on Monday. They seem to be really good at describing their products.

    I bet Speedway doesn't have any heaters like these...

  7. In my roadster, I took one of those modern square box style auxiliary heaters (I think they were designed for use in the back of suburban type trucks in the '70-80's) that looked completely uninteresting (like it came out of the 70-80's) and made a couple simple changes to bring it into the era. I made a new front cover out of sheet metal...with rounded edges and corners, I added a trap door to the bottom of the new face (and used the original side vents that came on the heater), I painted the new front cover with rattle can hammertone grey, I added some art deco era type trim (made using 3 strips of stainless steel bars welded together with studs on the backside (I scavanged from old oven racks that I found at the dump)), and then added a reproduction trunk badge from a '40 ford trunk.

    The plus side of this heater was it was cheap, 12 volt, came with a new heater core and fan. Works great.

    got a old hadeez heater somewhere...
    my opinion is find one that uses an easy to find modern shape core, if you can't find a core try a power steering fluid cooler...
    maybe use spray expand-o-foam and some wax paper to make a mold to help anchor it... and a 12v computer fan or two, low voltage, quiet, and easy to find... $0.02...

    I found some nice ones off epay but you gotta be persistent
    Usually have to clean them good and find a little 12v fan motor to make em blow but no big deal
    Here’s the one I put in my 36 coupe
    It’s a Hadees for 36 found in dilapidated shape with no fan motor on epay
    Rewired, replated the doors, polished the frame(it’s gonna get plated too)
    I’ve got a nice Montgomery Ward with a chrome plated case I should prolly sell

    Could you show a pic of the heater you started with, or if it's too off topic, shoot me a pic in a PM?

    My favorite is the Harrison. I have two of them set aside for both '32 projects. 32road_bright6.jpg

  13. Thanks guys...I started with something that looked very similar to this:

    https://www.millsupply.com/auxiliar...y-12-btu-m503012v.php?p=97236&cs=1+5393+5394#

    It may not have been this exact unit. The one I used was a swap meet score a number of years ago (it was unused and still in the original box). You get the idea though....and within context. 20181104_110917_resized.jpg

    Dang, that is neat! A factory one would not look as good.

    Nothing looks better then a restored vintage heater. Wouldn't even think about an ugly looking repop.

    I have my original in my '41 but after seeing some of these heaters no doubt there are folks who collect vintage heaters exclusively. That Harrison heater is very unique, never seen that model.

    I have an old one I found in the trunk of a parts car. I don't know if it leaks or not. Might try it some day but I really don't have any use for it as of now. It could probably be made to look decent. IMG_7004.JPG

    A lot of those vintage heaters are cute but will cost far more to get working right than just buying a good heater. I full and understand the why and have several small under dash heaters in the shed but outside of one rig that having "correct" is a must I probably won't use any of them because of the expense to fix them.

    Traded an old Sun tach for this Hudson heater...put a new heater core in it from a Ford F150 100_8961.JPG and a 12v converter...
    I have used the box heaters from Yogi's and Speedway, Vintage air...they work fine but are a bit expensive...enjoyed scrounging an old one back to life for some time and 40 bucks...

  27. I have a couple of old heaters but they don't hold pressure. I might try and cover a new one with an the shell of a vintage heater but for this year just going to go new style. Any luck with the new ones or bad luck out there?

    I had a Vintage air heater under the seat of my '37 for years. It made great heat, actually to much, there was no control on the water flow, so I hat full heat or no heat. The cab is really small so I didn't take much to stay warm. I always drove with the cowl vent open to regulate the heat. I also added a second resistor to slow the motor down even slower to make more manageable. I recently added a A/C unit with heat with a variable water valve. Best move I made, you can have warm but not hot air.
    Something to think about when designing your system. Maybe a cable operated heater valve?

    I agree with you on the control valve...put one in line and use a choke cable to operate if you can't do it manually in the cab. I use a valve from ebay...old Dodge/Ford part about 7-12 bucks ..
