Those of you that have followed my build thread may recall the utility trailer that I modified to allow me to be on extended SAR searches and have a place to sleep and have everything I need to essentially live wherever I am at the time. I also use it for my yearly fall 2-week trip to explore the backcountry of British Columbia.
Last winter I decided to get one of these, and finally got around to installing it:
Amazon product ASIN B09C2Y88GF
It is basically a knock off of the webasto but at 1/10 of the price. Since this is not a "mission critical" item for me, and based on the reviews, I decided to give it a go. An 8kw heater is way overkill for a ~6x12 space, but I have found running an 8kw heater at 2kw is more efficient than running a 2kw heater maxed out. And at minimal setting, they claim one tank of fuel (10L) will last 100hrs. I assume this means running it constantly, which I will not be doing.
Install was relatively easy, but people complained the injection pump was noisy - a constant "tick, tick, tick, tick" so I built an insulated box for it, and stuck that inside my forward cabinets. So all I hear is the fan, and a really faint tick in the background.
What doesn't come included is any way to exit the exhaust, so I had to buy one more length of bendy exhaust pipe and I used a marine sump port as it is double walled. I also had to build a mounting bracket for it (I didn't want a big boxy one)
Installed up out of the way:
I still have to route the heater hose downward towards the floor, but you get the idea. You can't see it, but just behind the heater to the right is a vent to outside where it can pull in fresh air.
This heater REALLY puts out the heat... it comes with a panel that you can program for time, when to come on, when to shut off, thermostat controlled like a furnace, or just use a remote to kick it on when you want.
The specs on it, well, on anything really, is annoying. I realize they are provided a perfect lab environment and giving you specs under ideal conditions. However, it does draw a fair bit of amps on startup (glow plug) and I realized with my fridge/freezer in combination with this heater in fall/winter scenarios with limited daylight, I would really need to up my solar game. I ended up taking off my 2 100watt panels and putting up 2 200watt panels. I put in a decent charge controller originally in case I would need to do this, so it was an easy upgrade. My buddy wanted my old (3yrs old) 100watt panels so it was a no brainer for me.
The local truck shop had an insane sale on series 31 batteries which have about 100ah for only $100 so I bought 2 of them. The same bud that wanted my old panels said I should go 2 6-volt and run them in series, but I had to explain to him the difference. While I appreciated his point, I was going for ah increase, so to double my amp hours, I would need to buy 4 6-volt batteries, which incidentally were NOT on sale. Again, a no brainer for me. I am tempted to go back and get 2 more for the Land Cruiser, but I would need to measure and verify if they would fit.
A full on 2 week testing will commence this fall....
