Was thinking outside the box and figured I'd share my thoughts on a possible heater option...

I wonder if a tankless, indoor, propane water heater could be used, along with radiant heating mats:

I'm thinking the tankless heater could be vented through the floor of the trunk space...

If you want to go to that much trouble you could use that water heater, and look for a fan/radiator unit so you get real heat inside the cabin.

I wonder if your propane heater is cost efficient. My diesel heater set me back 140 euros or 160 usd.
A broken ptc heater could set you pack a couple of thousands!

There are liquid diesel heaters, they are to be set up in line with the normal water circuit. If you're looking for a more discrete installation that is the way!

My tank less water heater I installed in my rental house cuts off if the inlet temperature goes above 90F.

The Eberspacher hydronic heater is exactly what you need and it is a lot smaller than any tankless heater I have seen.

I have not even bought it yet.
My hope is that they go on sale when it warms up. Plus I have been so busy with work I doubt I will have time to install it before spring.

Looks like a good product, but too pricey for me.

Sooooo i used about 1 liter per 300km.
Aka 1 gallon for 700 miles. And used during freezing temps and including preheat (by the diesel heater)

Quite satisfied. As i dont have to fill it on a regular basis

Excellent...
I was figuring 300 miles to a gallon, unrealistic, worst case scenario.
I was expecting at least 500 miles to the gallon.

But 700 miles to the gallon!
I would only have to refill a 1L tank roughly once a week.
Where I am it will get cold for 2 or 3 weeks then warm up to where it's bearable for a week or so. Then back to being cold again.
So probably use 1 gallon per month or less.

My tractor uses diesel fuel so already have it on hand.

Keep in mind i have the 2kw version not the 5kw. The 5kw will use more.

I also calculated it is actually cheaper to heat the car with diesel thsn with electricity.

I use about 1kwh per 40km.
So per 300km ~7.5 kwh.

7.5kwh at 23 eurocent cost me 1.7 euro
A liter of diesel is about 1.30 euro.

This is correct.
Exception is solar energy. But that is hardly available in winter.
