Heaters?

[keith oh]

My 35 has a manifold heater much like the Model A heater that uses the engine fan air blowing over a exhaust manifold heat exchanger directly through a hole in the firewall. I have not seen any others like it. It does take the edge off if its not to cold out. Has anybody else have one like it?

My 47 tonner has Ford hot water heater that looks just like the one in Dick Webber's picture. Only mine is not as pretty. Mine looks like it was added by the way the holes are cut thru the firewall.

I have a 40 heater that came with my 40. I am trying to restore it. Need a motor and trim clips to finish things off. I hope to install it this winter if I find the parts and get the time.
Merry Christmas!!

My 38 parts car had that exhaust manifold type heater on it. I likely still have it somewhere but would have a hard time locating it as I removed the engine over 30 years ago.

Southwind Jr. in my 35 pickup. All NOS guts. Still needs a little tweaking, but heats things up very well.

Have the stock Ford hot water heater in my '46 Tudor. Had the core cleaned out and it works pretty well. The defroster is a little "iffy" but better than no defroster.

My `35 1-1/2 ton has a nice water heater, and appears to be factory or at least Ford. It is odd how it is plumbed, and has some plastic replacement tees and wrong clamps and such. I'd love to find out how it supposed to be plumbed.

This is the heater shown in the 46-48 sales literature:



This is the fresh air heater that became available at the end of '47 and is in my car:



And these are pictures of that heater in my car:

The inlet of the air duct that takes air from in front of the radiator:



That then goes along under the hood:



Meeting the fan on the firewall when the hood is closed. The cable going up over the duct controls the damper in the duct (bottom of pivot shaft seen near fan port) to control the air going through the duct.



Into the heater coil on the passenger side of the firewall.



To go out both sides of the bottom plus a slit along the bottom unless that damper is pulled up to divert it to the windshield.



Three dashboard controls. Left for defrost. Middle one direction two speed fan switch. Right controls the damper in the hood duct to control the outside air coming in.

My 41 has a switch that has high and low in forward or reverse. Does anyone know what the purpose of this is as I don't see the advantage of reverse.

Hey Old Henry - how well does that fresh ai heater work - that is some set-up!!

[Blu Dice]

My 1st car was a '41 Plymouth coupe (with a back seat)that had a hot water heater under the driver seat (disconnected) - I've never seen another one and always wonder how they functioned.

Has anyone tried the approximate 7 X 7 X 7" hot water heater sold by Summit Racing ? looks like an easy mount and fit. Don't know about output listed at 12,000BTU. Zeke

This is a box-type heater I bought twenty-plus years ago from J. C. Whitney for my Model A but was never installed. It looks to be the same one you are describing. It did not come with heater hose or shut off valve. It is designed so that a defroster could be hooked up with a bit of duct hose and other items. The fan is two speed and it came with the switch. I used it in my '32 and it does a good job.

Oh yeah, I paid about $70 for it back then.

My 48 had a heater in it one stage ( square Ford thing with the flaps). I came with the parts for my car. It is still boxed away. I never bothered to install it as we have a temperate climate here.....anyway I have a "dirty great big heater" that radiates through the firewall and up through the toe board of my vehicle.

That switch was to control the stock recirculating heater I showed in Post # 28. If you read the description of that heater you'll see that the fan could blow forward through the coils and into the passenger compartment for more heat or backward, drawing air through the coil and blowing it against the wall for less focused heat. Plus you had two speeds each direction.

I think the heater works great. I get way more heat than I usually need and plenty on even the coldest drives (drove it down to 7° here: http://www.fordbarn.com/forum/showthread.php?t=93137). Plus, because it brings in fresh air the windows rarely fog up so better visibility all 'round and it pressurizes the inside of the car to keep drafts of cold air coming in any cracks or gaps. I like it. But, then, I've never had anything else.

The knob on the switch should say Indirect-slow & fast, Off, Direct-slow & fast. Direct heat blows air through the core and out the front of the heater. Indirect is reverse and Should be for Defrost, and as Old Henry says, for indirect heat, as it will suck air through the core and blows it out the back side of the heater against the firewall.

Thanks ,Old Henry and Dave. Mine is all there and works but it seems kind of pointless but it's nice to know what it's supposed to do.

Further to my post - my Coupe had a dealer installed gas fired heater installed back in teh 30s' (that was scarey!) which came with a nice factory match dash mounted heater push/pull knob and cable that went to an interior door flap to open and close the air. When I converted to the 1940 hot water heater I used a modern water shut off valve as you can see in the picture and re-purposed the heater cable to operate the valve. Click on picture to enlarge

It sounds like you might have a GENUINE FORD accessory heater. If it is like this one, you do. They are pretty scarce.
Also shown, is the original FORD adjustment device.
I believe the lower inlet tube, in the third photo, is the correct one.
