Foils for boat

Additional insulator in the icebox

On a sailboat, the electrical energy is limited. Who wants to be self-sufficient long so sparingly to deal. The biggest power consumption has the refrigerator, especially older models make themselves noticeable. Instead of wrapping the cooler with additional insulating material from the outside, they can be lined on the inside with self-adhesive aluminium foil. The approximately 0.100 mm thick aluminium layer is very resistant and reduces power consumption considerably, as it reduces the heat radiation.

Principle thermos

Article from the sailing magazine “Palstek 6/09”:

Everyone knows the principle of the thermos, with which you can not only keep hot drinks warm for a long, but also cold drinks cold long. To effectively save power, you could wrap the outside with his refrigerator additionally insulating material or install a new fuel-efficient refrigerator. An effective alternative is, however, in the lining of the existing refrigerator with adhesive aluminium foil, for example, 0.1 millimeters thick. Aluminium has the property of emitting, with its high reflectance of heat radiation from wherever up to 95 percent as a mirror. Wherever cold shouldn’t get warm, aluminium foil or aluminized plastic sheets are used; in outdoor sleeping bags, cold as protector for injured, in space, as a heat protection areas behind stoves or heaters and so on. My fridge in the boot (mediterranean) is stuck since early 2008 inside with aluminium and consumed to my delight far less energy than before the measure.
