Idea for heater

Post by HowardT64 »

Got this crazy idea. I take the blower motor, heater core, shroud... all off and put a cover over the hole. Instead go with electric heat. This will allow me to get to the passenger side spark plugs easier and clean up the clutter under the hood a bit.

Any thoughts?

Like the idea but you still need a way to direct the heat to windsheild and some method to move it. :idea:

not a great idea in my opinion, i sure it can on occasion get very cold there and anything electric will not supply the BTU's you are going to need, if you did find something you probably need a extra battery and a killer alternator.

If you were dying to do this perhaps re-routing the tranny lines and put some tranny coolers in the rear with a electric fan?....only shortfall is that the tranny takes a long time to heat up

I used to run a school bus heater in my commando. The type of dual fan heater that is under one of the passenger seats.Mounted it behind the seats and ran plumbing to it. It put out so much heat even on the low fan setting that I could roll the windows down in a blizzard and still sweat. it did save my butt one summer day when I lost the fan in the middle of nowhere. Turned it on hi and the temp actually went below normal all the way home. I bet I lost five pounds during that ride too.

Electric heat is not practical for a car.

Look at the BTUs delivered by, say, the Mojave aftermarket heater. They say 12,000 BTU, which is unfortunately meaningless without some time frame. BTUs are like calories ... 2000 calories a day is enough to live on, but at 2000 calories a year you'll starve. This must be BTU-hours, which is the same measurement as watts but in different units. 1 BTU-hr is 0.293 wattts, so to make the same heat electrically at 100% efficiency requires 3515 Watts. Watts are Volts times Amps, so if your alternator makes 14 volts when running, you will need a constant 251 amps to equal this aftermarket heater - and this is at an impossible 100% efficiency. You can see the problem here.

How often do you tackle that spark plug? once every 5 years... laying on my back it is an easy task... In fact the worst one is #7 because of the brake booster and hydraulic lines.

As Tim said, the BTU are keys, you may need to upgrade your alternator... and wiring to power such a beast of a heater.

This is all for changing spark plugs?
Didn’t have to do that when doing plugs and wires but did have to disassemble the heater box to remove a mud wasp nest blocking the plenum door in order to get heat during the winter.
