In hind sight, after reading my message today, I'm not sure if I can treat
it as an hourly unit. I have to find a better reference book and report
back on that part. The calculation of BTU's in that volume of water looks
fine though.
See what happens when you go out on a limb and type as you think! I'll do
my homework this weekend and get back with a short confirmation, or
correction, on my new units of "1500-Watt-heater-Hours".
