Built your own Manifold Heater
As long as we have not been seeing any snow or salt on the roads yet in the Midwest, I have still been enjoying some driving in my Model A's. The manifold heaters I have in my cars seem to make the interior temp comfortable enough to keep the wife happy.
We have all seen the Autolight and Otwell Manifold heaters that are made of cast iron. I am wondering if it would not be that hard to make your own manifold heater out of sheet metal for use over a standard manifold just to direct some warmed air inside of the Model A via a hole in the firewall. Please find attached a .pdf file of some old 1932 Patented ideas for yet another style of a Model A manifold heater. A_AUTOMOBILE_EEATER.pdf |

Re: Built your own Manifold Heater
I have one on my coupe that is similar to #3 PDF, except it has a round exit where it meets the firewall. It's made from 1/8" plate steel.

Re: Built your own Manifold Heater
Someone in our club had one in the original Ford script box that was tin and fit the stock manifold. It's the only one I've seen like it.
This is another one of those items that needs to be reproduced. |

Re: Built your own Manifold Heater
Tom,
I have a rusty one-half of a sheet metal heater which came with my 1930 Model A & was stored under the seat. Instead of horizontally surrounding the manifold, it was positioned vertically around the vertical part of the manifold "and" the vertical part of the exhaist pipe "including" the manifold/exhaust clamp. The two halves were bolted together, & one half branched off into an integral tee configuration, thus providing heat throught the fire wall to inside the car. Appears it could have heated quite well; however, for a "safety" announcement, it may be important to consider that "if" the manifold clamped leaked, the occupants would have entered into a very peaceful sleep. Another vintage accessory feature I still have installed is an interior flat, round sheet metal heater door. It rotates & slides up & down on a pivot pin on the inside of the vehicle with movement controlled by an enclosed heavy wire with an upper, attached handle located under the passenger side of the metal dash whereby one can regulate the amount of heat entering the car from the inside; or turn the heat all the way to OFF. Have no idea where this came from, but this interior pivoting manifold heater door accessory works very well. |

Re: Built your own Manifold Heater
Do any of these, even the most common one, actually produce enough heat to be worth it? Or would an extra pair of underwear and socks produce the same amount of warmth?

Re: Built your own Manifold Heater
Mine work pretty well in the coupe and pickup because the passenger areas are small; the tudor is just OK, not great, better thannothing.

Re: Built your own Manifold Heater
I have the cast iron Autolite heater with a rotating cover on the inside of the firewall. I am in restoration phase now but the mechanic that worked on my car (Fordor sedan) said the heater would drive you out if opened all the way. I think if that is true the metal cover will get too hot to handle . I am going to rig a bowden cable to work from the dash area. Bill G

Re: Built your own Manifold Heater
Last month I rode in the rear seat of a 31 Town Sedan with a manifold heater and on a 27* day it was very warm inside the car.

Re: Built your own Manifold Heater
If my wife's feet are kept warm then Mama's happy and when Mama's happy I get to keep happy. The exhaust manifold heater works good enough for this....
I googled the Internet on the Model A exhaust manifold heaters and found this very well done article in the Wichita A's newsletter from last year. http://www.wichitaas.com/newsletters...t%20Review.pdf Now I am curious as to how many manifold heaters were actually offered back in the day. I have started a collection of photos of what I could find so far.

I have never seen this one and didn't know of its existence until your mention. I found a picture of it and a great heater article at this website. It is from the Maple A News from 2006. I am greatly appreciatiating the great technical articles put out by the local clubs in their newsletters. http://www.vtmodelaford.org/manmarch06.pdf OK sheet metal guys Tom has put out the idea for this heater assembly to be made. Anyone want to take on a challenge to make this Official Ford Car Heater? |

Re: Built your own Manifold Heater
When my Dad was alive and owned the truck I have now, it got hot enough in the cab (in the summer) with the bypass door open but the connecting tube still installed that it started to melt the floor mat. I made him a bell cover that slips on the bell to stop the heat from coming into the cab.

Re: Built your own Manifold Heater
There is that trap door on top rear of the Otwell Health Heater that is supposed to be open for Summer. It looks just to be in the right spot to help boil the gas out right of the sediment bulb though.....

Re: Built your own Manifold Heater
I found a "Red Head" Manifold cover heater in a shed once while hunting for needed parts. It is cast aluminum. Red Head made aftermarket water heaters into the 40's but that one is the only hot air manifold heater by that brand that I have seen.

Re: Built your own Manifold Heater
At Hershey I saw a heater that was a large shell that fit over the entire muffler, it had a floor register for the rear seat floor.

Re: Built your own Manifold Heater
I think the funnel is off another heater. It would be redundant to the cover scoop. The flex tube at the bottom of the elbow was for pre-heating air into the carb. There would have been a fitting to attach, probably with a shutter, to the carb.
