Better insulation for ice/refrig boxe??

[EDDIE...@aol.com]

My biggest battery drain is my refrigeration system. It doesn't seem that there is any insulation around the ice box and it is right next to the engine. We would like to insulate the refrig . Has anyone had any success with this project?  Ed and Louise Smith "Allmand Joy" NPR, FL

Eddie,

I insulated my ice box from the inside. At Home Depot I bought the insulation with the highest R factor available. It has a foil surface on one side. Then I cut it with a razor knife to fit the surfaces in the box. I secured it with Aluminum Tape to the sides of the box and covered the seams with more tape. It improved the holding capabilities immensely. The size of the box was not affected substantially. This is the second time I have done this project on a boat and it worked extremely well in both cases.

Cheap and effective, and not overly time consuming,

Eddie, 

For comparison how long does a 10lb bag of ice stay frozen with the new insulation? 

Thanks

I'll try that next week and let you know. Ed

Thanks Ed. I have been looking at Yeti coolers and they say ice lasts a week in their coolers. It would be interesting to know if we could recreate that efficiency.

On a different note, I always cleaned and filled empty juice, soda, or box wine bags with water and froze at home. I used the containers as block ice. When it melts there is no water in the ice box. Also you can drink it when melted.

Good ideas. We do the same. Ed

We have had ice last a week in our cooler from Sam's Club and it cost  1/5 the price of Yetis. Ed

That is a good idea. I'll try it next time.

Eddie,

What brand of cooler did you have from Sam's?

Tom, I'm at the Grand Canyon right now but I'll be home in a few days. I'll check and let you know. Ed

Original specs states 3" of insulation which is usual refrig mfg recimmendation though more is always preferred. I'm investing in replacing the AdlerBarbour with higher effciency unit.

I did the same things, plus I caulked the insulation to be air-tight; then, to keep the insulation dry, I lined it with FRP board (from Home Depot) sealed with epoxy. It worked great, was easy to clean, and was watertight. I also installed a Nautic Cool Blue unit and a divider like they suggest so that I had a freezer and seperate fridge
