Better, Diesel-Fired Liquid Heater for 2011-2012 Leaf

Fri Jan 11, 2019 1:12 am

Winter on the 2011 and 2012 kills range, using the heater kills it even more.
I'm luck that I have at 2014 battery with all 12 bars so I'm not suffering too bad.

I had seen these before on the diesel truck forums but didn't know if they had been used on the nissan leaf.
Then I found this:
http://www.mynissanleaf.com/viewtopic.p ... 76#p545676

Paulsp looks like he is enjoying his diesel fuel fired air heater.

I was considering one of these or the diesel fuel burning coolant heater. One of the german made Eberspacher brand ones, not the cheap chinese knock offs. I don't want to fire bomb my own car, I actually like this car.

I mainly want the defroster to just be blasting heat. But that doing that in the leaf kills range bad.

I think the Eberspacher has a circulation pump built into it. I could plumb the coolant heater into the coolant loop and run it with the electrical heater. Hopefully the electric heater would barely draw any power.

If I use the air heater and stick it in back like paulsp did I just don't know if it will do much for defrosting.

What do you think?
Leave the coolant loop alone and just use the air heater or plumb it in?

Why do you think this should be a new topic, apart from the existing, informative topic on the same subject that already exists?

That post was specifically about the diesel fired air heater.
I am leaning towards using the diesel fired coolant heater, which it doesn't appear that anyone on here has tried to install. I would like to use the diesel fired coolant heater unless someone know of a good reason not to.
Then if I know the coolant heater won't work for some reason, abandon that idea and copy paulsp to the letter and call it a day.
So should I have just did a thread hyjack and started asking about coolant heaters on an air heater post?
Seems kind of like a jerk move.

That is the status quo here. combine a dozen topics into one thread then do a tour...

Using the existing coolant loops does sound like a good idea if it would work. The current heater must have some sort of thermostatic control so if an exterior heater was added that should reduce the electrical load.

A couple of questions though....

1) isn't the coolant used for the heater on the 11/12 models looped through the motor and charger as well? I was into Leaf's back then and have no knowledge about the 11/12 versions but I thought there was one coolant loop that combined the heater and the motor/charger so that the heater could use the heat output from the motor and charger. If that's the case, it might not be a good idea to heat the coolant too high since that coolant is being used to control the temperature of the motor charger. I guess if the temperature was set to the same level as the heater raises it to then there should be no problem.

2) is the plumbing accessible enough to make this work out? As long as no metal has to get cut to route coolant lines it sounds doable.

Not true. The "status quo" as you mistakenly call it, is to let people start multiple topics on the same subject, ask them if maybe that isn't the best move, and then be unable to locate all of the topics again in the future. Few topics actually get moved or combined.

The coolant loop for cabin heat is separate from the loops for cooling the onboard charger, motor, and inverter.

How about a slight but helpful title change? "Better, Diesel-Fired Liquid Heater for 2011-2012 Leaf"?

Do it.
Since I would like my install to be specific to the 2011 and 2012, focusing on the coolant heat loop.

If there is an "add a coolant heater to a 2011-2012 leaf" post I was unable to find it. My bad.
Remember I'm new, so I'm not going to remember a post from a few years ago like the old timers.

I have already determined that for me to upgrade to a 2013 or newer leaf would cost at least $3,000.
Because there are few to no leafs for sale here, the ones that are for sale almost always have battery degradation so I would have to have one shipped in from a cooler climate, like i did with my 2011, then my resale market here for the leaf sucks.
And I believe that this mod will be superior to the newer heat pump cars, you know, great hest with almost 0 loss in range.

So I got no problem spending $700 to $800 on a heater.
