Aftermarket heater blower

I have run into space constraints with my electric 109 and need to find a smaller blower motor for my heater. I plan to use a Mark IV distribution box on the inside which can house the heating elements so all the under hood side needs is a blower. Does anyone have any experience with these and or better ideas?

I am thinking I need something like this:

However in an idea world the intake will be on the opposite side as shown and have a flange that I can connect a tube to. 3 speed preferred, and as powerful or more powerful than the original .

Another very similar one:

Use a blower fan from a RRC aircon unit. I have a couple. I can bring you one at HH if you want. Fan speed is determined by a resistor. Use a generic AC Delco three speed one they have 1/4 inch spade connectors.
There are also in line 3" bilge blower fans, 3" vent blower fans and the mac daddy PAR/Jabsco 4" blower. Those are available flange mount or freestanding with hose barb in and out.
Spal makes a nice single squirrel cage fan.

Do you have a picture of the RRC aircon blower? It would certainly be fitting to have one from an RRC!

Is it like this? http://www.landroversonly.com/forums...-burned-48960/

I have seen lots like that but was ignoring them. I guess I can make a custom box myself and use any of these.

Will search for the others thanks. I looked a few weeks back but wasn't getting great hits.

So just need the blower in format that I can fit in the engine compartment side of the footwell with a big ass battery box limiting the size and position.

Are you planning on using electric resistance heating elements? If so, I suggest you do some calculations about how many Amps you're going to need for heating. Much better to go to diesel or even fire wood.

Yes all electric. I have 800W (60A) at my disposal for 12V which should be plenty and it has very low draw from anything else on the 12V side. I have considerably more at higher voltages

The RRC one is a self contained flange mount blower. Does not need a box.

800 wats will give you about 2700 BTU of heat. Pretty pathetic IMHO. A standard heater on a vehicle puts out ten times that much heat. Even more in many cases.

I'd be willing to be a dollar that Charles will not drive the EV when it's balls cold weather.

Keep in mind it really doesn't get that cold here, and it will be wearing a pickup cab in the winter, so not a lot of area to heat. The bar is pretty low in terms of the original heat, and really I just need to make sure I can defrost the windows (for safety). Everything else is gravy.

Bill, why do you think I won't drive it in the cold? I drive my 88" in the cold, and the defender too, both of which have larger areas to heat and marginal heaters.

I can't make happy hour this month. Could I bother you for some pics and dimensions? I don't want to wait a month and find I need a different plan.
