Well, when the list was mulling this over,
I didn't have much to say.
Mostly, because I have just bought the 12,000 BTU Suburban heater.
And I don't have any practical experience yet to report.
I have just wired, plumbed, and run it for about an hour.
It seem to work very well, and I feel I'm going to be very happy with it.
Someone on the list said they are 5 amp?
This may be true of the larger ones, but the 12,000 Btu
Label says 2.8 Amp. 50 W.
The Battery that I have is the Everstart Marine 1-n.
Cranking Amps 1000. Cold Cranking Amps 875.
I don't know how to figure Amp Hours from this,
unless this is the amp hour designation.
Also I usually sleep with the heater off, unless were talking sub freezing
temps.
So the heater actually would be on mostly in the evenings,
Extending the life of the battery.
And a Second, Extra battery could be added
along side the 1st extra battery.
under the sink.
Using the above Information,
could the list's Electrical Guru's
please refigure Battery Life for me,
so I Can know what to expect
from this heater?
best,
