I put an isotherm in, but that's a different story as I added batteries
where the old water heater was and thus reengineered the boat to move
the water heater to a spot were the boat would be in balance and on its
lines.
The point of this email, though, is that if you're replacing the water
heater you should also replace the wires. Wiregets old. And I recently
had an idea I've never heard before, but wish I'd thought of it when
doing the wiring. If possible, on the AC run, add a junction box with
one of those 'switch/timer' things. You know, you turn the dial or push
the button and set it for 30 to 60 minutes, and then it shuts off. I
haven't rewired a house in 20 years, so I don't know what's currently
available.
I've noticed that it only takes 30 minutes for the AC system to bring my
tank up to temp, and thatwill last all dayunless I have guests or decide
to clean the galley. Leaving the AC heater on just wastes money. Now,
you rich folks up there in the US and Canada probably don't care, but
these Mexican marinas make more money on electricity than they do on
slip fees. If you're not paying attention, you can actually spend more
money on electricity than the actual slip.
