I think the ice will radiate cold and the Styrofoam will radiate nothing. The ice will help keep the unit from running so often.
IF you own a freezer......

My thinking is the styrofoam would fill unused space and therefore require less cooling needs and shorter cycles. Or maybe too many cycles? Inquiring minds....

At the end of the day, how many hours/day the freezer runs is a function of how much heat flows in. Adding mass, like milk jugs of water reduces how often it cycles, but not the running hours, to a first approximation.
I added two inches of polyurethane foam to the lid of my chest freezer, and it significantly reduced the power use. Unfortunately for me, the condensing coils are wrapped around the walls of the freezer, (putting more heat into the freezer) so the walls can't have extra insulation. I would much prefer to have one with exposed coils on the back.
I have seen vacuum insulated freezers, but $$$ doesn't even begin to describe it. Even the SunFrost freezers are $3-4,000, to use perhaps 25% of the energy of a normal appliance.
Yes, California imports a lot of power, most of it is hydro from the PNW, although the per capital energy usage is the fourth lowest in the country. There is a huge DC power line that runs from Washington to LA, with the return power flowing through the ground (saves wire). The power flows south in warm months, north during the winter. More here, if you are interested. By 2019, solar made up 20% of all power generated in California
Household batteries are the big thing in California at the moment; battery installations have six to nine month waits. In addition to running homes through outages, they also push solar energy out after dark, as it were, as most installations are on homes that have solar as well.
The ROI on solar in California is 5-7 years for most folks; batteries are more variable, ranging from 1yr to 20, depending on lots things.
All the best,
Peter

The instructions say display first, then the sensors. I tried it the other way and sensor, display, sensor. Nothing worked. I am using both sensors in freezers and setting the limits accordingly which the instructions say you can do. For grins I just reset the display and cycled the batteries and left the limits factory. Then put one in a fridge and one in a freezer. I will give it a few hours and check on it.

Well look at this... it seems to be acting better with one sensor in the fridge and one in the freezer. Have not tested alarms yet, don't want to rock the boat to quick. One step at a time. Both high alarms were set the same and both low alarm were set the same before, maybethat confused it. I noticed that fridge reading started higher than the freezer like it was biased somehow or had a different start temp. Everything is slow acting so hard to tell

Went and got lithium batteries (since Amazon left me high and dry) and then had enough batteries to get both setups powered up at the same time. Reset both displays and all 4 sensors once putting new (incl lithium) batteries in. Put all sensors in the same fridge and freezer for this test. I had to reset the one on the left to get it to start responding. Long story short I now think I have one dead setup. Not that the one on the left will not function, but that it is unreliable. Functions sometime.

Irks me that cities are wanting 'clean injection sites' to save those druggies useless lives.
Heck I suggest they install them at the cemeteries and maybe they'll get the message.

Natural and saturated fats are not necessarily bad for you; just another form of energy with the bonus of not spiking your insulin levels.
Your body produces about 85% of the total cholesterol in your blood. Your body uses cholesterol in the manufacturing of new cells, so cholesterol is needed.
I have my C-reactive protein checked when I have my bloodwork done, usually once every 8 months or so. That test will show how much inflammation you have going on in your body which, coupled with high LDL and high triglycerides, is cause for concern. High cholesterol with low CRP and low triglycerides is not necessarily a cause for concern.
Drug manufacturers make a lot of money on statin, or cholesterol lowering, drugs.
Ancel Keys, the doctor who came up with the whole low fat/high carb diet craze, has turned this country into a bunch of overweight diabetics.
