I am seriously looking into this part of the project finally.

I want to run one heater up the front in the belly pan area, and hot air up into the original vents.

I also want to run a supplementary heater under the back seat.

I would prefer to use new stuff like as shown in a Jayair catalogue. Anyone got any ideas on which model?

Also, as the heater circuit is a bypass for the Subaru engine, does this mean I won't need a heater tap?

Or is it a bypass/ close circuit type of tap?

Does anyone think I will need an electric heater circuit water booster pump? Does the original Subaru heater circuit flow well enough?

Ok I have just put a EA81 in the T3 and what we did for the heater is .
As you said the heater is on a bypass tap so when the heater is off it moves the water from side to side of the engine.
with the heater on the water goes through the heater as it goes from side to side, so we used the bypass tap from the Subie Leone donor car and set it the same has they had it.So when I want the heater on I turn the T3's heater on and then pull the cable to turn the Subie tap on and it works the same as in the Leone.
In a bay you would have only the cable to the Subie tap to turn the heater on.

I hope this helps

Have a read here about the cooling/heater circuit.

this is the unit I have in my buggy.



they are available aftermarket from;
The Ingram Group
Ingram Corporation Pty Ltd
1/8 cooper st
Smithfield NSW

I'm not sure if the details are right but look them up and you'll be able to get what I got. Mine does both aircon and heating. You just need to run lines for it. You can see how I did it here...

The next diary page also includes another mod I did to make it work well.

I got one for my race car out of a toyota coaster bus new from the guys that do conversions into campers . There are around three of them on the floor in these buses .

For the rear one I think I have a Nissan Vanette rear under seat heater unit sitting around somewhere if you want it. If I can find it.

Hi

I had a troop carrier one under the rear seat on my old bug, it didn't pump out a lot of heat at first, but I kept recycling the air and in a short while it made a quiet a difference.

You need to sort out the heater tap issue with a Subaru motor, maybe a 4 pipe one from a Commodore, but you would need to make it manual control?

Steve

I have a simple tap on mine, the water cycles round through a bridge in the heater pipes, when it's winter I turn the tap on so that allows some of the flow to come through the pipes that run to the heater and back. Lots of old cars did this. Tap on for winter/off for summer. My switch in on the fire wall in the rear of the car.



The great thing about this is, you can mount the heating unit wherever you want and all you need is a fan switch in the cabin. Afterall, in melbourne you only have cold and VERY cold, so you won't need to turn the tap off very often anyway.

Simplistically speaking, you don't really even need a proper heater element. an oil cooler with a small thermo fan on top of it would do just as good a job. You'd just want to make sure it was cover in a little so that busy fingers couldn't touch it if their hands went near it.

btw, this is the post from when I did it...

hey pete
give custom vw a call they where using troopy heaters mounted under the front of the car (modifying the outlets on the heater core) and then running it into the original kombi system.
not 100% sure if they are still doing them but worth a try.
cheers

Hi Pete...i know you have your radiator underneath but here is an alternative option to consider...just scroll down til you see my post... http://forums.aussieveedubbers.com/viewtopic.php?tid=70705  this works great even in this primitive form

not much rain gets in here pete

and it just goes out the bottom had a warm dry run home in pouring rain last night



[img][/img]

so how does your radiator work? how does the air get into it?

pete...air goes in the normal kombi ventilation grill but behind that everything has been removed...



[img][/img]


then there is a V6 holden radiator enclosed in a plywood box...



[img][/img]


fits in nice and snug and works extremely...air exits though the hole on the floor


[img][/img]



there is a ventury effect which sucks massive amounts of air thru....ask Wes to explain

when i first got it working i ran it woithout a thermostat but it would never warm up...so put it back in....even now the computer never starts the fan so i put a manual switch there just for peace of mind heheh

very cool. Never would have thought of that...I mean, I never would have thought that small vent would have been enough, but with the venturi effect it makes perfect sense. You should glass up a bunch of them and sell them as a kit. great idea there. I'll have to show this to my brother. He wouldn't mind a conversion but doesn't want to ugly the front up of his lowlight. I also like it much better than mounting it under the car where sticks and rocks can get it.

Hi

That radiator set-up is brilliant. Does it transfer much heat to the interior?

I only used the stock air conditioning front apron on my old bug for a radiator intake.

Steve

i had this setup going all last summer and no heat in the cabin. i have the subaru dash installed as well and the temperature gauge never ran above normal because i used a holden VN radiator which had a remote filler reservoir i just have an air bleed at the front and the radiator cap at the back...it all works great

Helbus, I am using this unit in my buggy. It is both a heater core and air con evaperator. It is a HOT rod air unit, but you can buy them through a distributer in Perth.

For the one under the rear seat, get one from a Type 25 Caravelle (might be called a T3 over there).
Squirrel caged fan a matrix (fairly small & compact) which you can shut down the coolant flow from - I think you're aware of the probs doing this on a Scooby lump.
My front heater is a total gash up! Alfa Romeo matrix, MDF box, 3" Blige blower & PWM module from Maplin (Radio Shack sorta place). This is hooked into the original VW heating system and works a charm.

Instead of using a switch, pop down your local plumbing supplies & get a room thermostat (for your house). Wire this in place of the switch on the relay. Job done for around 7UKP (over here, 14AUD)

I have to look into this now it is Winter again

I still have to make a camper floor so it's not mounted and I left space up to top compensate. Just the back so far. 60 series 'cruiser heater plumbed to an ea81.

I bought one of these for my bug. I'm going to put it under the back seat. It has a fan and is a pass through so it should not cause problems with the subaru.
