3 - Would it run the hot water heater?
1. The usual way via a regular plug to a 3 prong Marinco dealie. Be aware that it only supplies 10 amps or so (13 amps momentarily). I know this because I've had it cut out using a Makita circular saw with intent on some knot-filled lumber
. Slowing down a bit caused no further issues.
The only question is the term "floating ground". There's some question in my mind about how to ground these units when using them as a charger
into a three-prong set up. Two prong power tools? They work fine.
2. A qualified "maybe". I have a Marine
Air 12,000 BTU AC/heat pump system, that eats DC amps to run but needs a AC-driven March pump to circulate sea water to either cool or heat the boat. From the numbers, a Honda 2000 may
have enough "surge" amps to kick off the AC side plus the initial surge on the DC side, which drops to six/seven amps when actually running, but my instinct is to acquire a second Honda 2000 and to couple them together to remove all doubt. Also, having two gives me about 25 amps in total, enough to run the boat in econo mode and keep the batteries charging
at the same time. Your mileage, etc.
3. Depends on the hot water heater, doesn't it? I have an Atlantic T6 something, a six-gallon unit plumbed for heat exchanger
(preferred) or "dock kettle" AC use. Works like a charm, and draws (I think) 10 amps, which is close to the limit of the Honda in "econo" mode (which I recommend for the quieter operation and the increased run time).
I use my Honda as "supplemental" or tertiary power, after the alternators, and the solar
panel/wind generators are considered. Instead of firing up the 2000W inverter (notice that the inverter/charger and Honda are sized the same), I fire up the Honda if I want to use a power tool for 10 minutes (I have a steel
boat and use a lot of power tools). In some situations, I find it better to keep the inverter off and just run the Honda, like if I was running air tools and a compressor
...and a Koolatron...on deck
Lastly, of course, you can use them for general charging
or to avoid having a built in inverter. I found they compliment the inverter in the same way that AIS
...nice to have and gives you options!
