Recent thread re someone using 8 amps continious 24 hours per day and having battery
North USA currently has a "heat wave". (Well, if it was Australia
95deg F/35 deg C is just a normal warmish summers day... )
One of the big users of electricity is the fridge and freezer
, but you may be able to cut usage down substantially.
The Dometic freezer
I have is rated to -18c/0F BUT the minimum temperature cant be attained "if the ambient temperature is above +32C / 90 F". So on these 95 D days you are stuffed by at least 5 degrees (more as your air intake probably has a higher ambient temp due to the proximity of the compressor).
So a freezer striving for the recommended freezing temp for frozen food storage
will run 24/7 and still not get down to -18/0.
I dont set it that low... Mine is about -7deg C / 20F and everything is solid as a rock. Meat will still keep for 6 months if I dont already fang it. Water
, of course, starts freezin, in practice, at -.5c/30F.
So why do we need those very colds temps? ICE CREAM! The freezing point of liquid sugar and High Fructose Corn Syrup is much lower, and when you consider that ice cream is about 50% air the freezing point is lower again. Technically ice cream is a 'frozen foam'. Its just firm at -12C/10F and melts bloody quick in the the cockpit
when its 95F outside.
To save a lot of electricity dump anything with sugar, HFCS, air, processed ingredients and stick with water
intense foods like meats.
Meat will be quite solid at -4C/25F and will be quite safe to consume, no freezer burn etc for at least a few weeks.
The bad news maybe no icecream on the boat until the weather
cools, but the good news is theres an ice cream shop not far away....
