Not just comfort. Yesterday it was 20F and I was driving around with out the heat like usual, hit a big puddle, water splashed up on the windshield and instantly froze over.
Fun times.

I had a similar experience early on with my volt. It was around 20 degrees outside, as usual at that time I didn't have the heat on. The windshield started to fog a little so I put the defrost on and a very mild 68. The windshield instantly fogged over completely at 60mph.

I no longer skimp on the HVAC settings. Save 50 cents to wreck the car because I can't see... yeah.


Is there any room to have a small honda generator to power an electric heater? Could also use it to add power to at least the 12v system and save energy from the dc/dc converter.

So we can agree that not running the heat to save range could be dangerous in the winter.

I just need a 40kwh battery and a diesel heater and I should be all set.

I'm not very familiar with these diesel fired coolant heaters. Will the stock heater also try and run or is there a way to defeat it?

On a bus, you don't get much btu heat on extended idle. So the webastos are plumbed parallel to the main system such that the kiddies dont whine they are cold. You switch off & on

The stock heater will only run if you switch it on, but if you need it to keep the windows defrosted,you should be able to rewire the heater away from the Leaf battery, and run it on an auxiliary generator, and if your aux gen is liquid cooled, you should be able to put it's radiator in the car for heat.

I actually want the stock electric heater to run on start up.
It would be a combined 32,000 BTU per hour. Then as the coolant loop temperature rises the electrical heat tapers off after about 2 or 3 minutes and the diesel fired heat should take over.
I found that if I turn the heat setting down to 60F and drive the car in eco mode it will only send like 300w to the heater.

Yes I can defeat the stock heater but in don't want to.

There are air heaters and hydronic heaters.
I want the hydronic heater.

then, you are talking about routing the coolant from a liquid cooled diesil engine into your cabin? So, it doesn't really matter how many KW you get from the ICE, just how many BTUs of heat? you could replace the ICE's radiator with a heater core, or you could move the ICE's radiator into the car, or with swithcing valves, you could vary between the two radiators. Beter to keep the exhaust outside.
