Conserve Energy with a Converted Chest Freezer
Refrigerators use more energy than any other appliance in a household. The US has over 200 million refrigerators running at this time. The temperature controller that I designed combined with a chest freezer will out perform any energy star refrigerator by a factor of 2 per cubic foot. Shrinking the size of the chest freezer will increase efficiency even further. In our case we switched from a upright energy star refrigerator to a small chest freezer and reduced our refrigerator energy usage by a factor of 8.

THANK YOU! I live off-grid as well and have been searching high and low for greater efficiency in refrigeration. Your solution is saving me hours/days of time (not to mention many hundreds of precious kilowatt-hours...)
I just posted an article about chest freezer conversions over at EZine Articles, under the title "Money-saving kitchen tip: turn an old chest freezer into a high-efficiency refrigerator." It links to HSHS and promotes your invention. Hope it helps. Happy Thanksgiving! Rick, TaylorSprings.blogspot.com
Got it! Thanks!!!
Hope you can get comments from older blog posts..but I have a question.
What sort of energy demand would a smaller, say 5CF "new", chest freezer conversion to frig, have with one of these devices?
Looking for a very low energy usage frig for an off grid cabin in far west TX.
Would this set be better than a Sundanzer 12V DC powered frig?
Thanks and we check your blog daily...very informative.
@littlefoot: Good questions.
The 5CF sundanzer retails for $1150 which is $1,000 more than a ordinary chest freezer. It's draw is about 1/3rd of what a converted chest freezer will draw which is impressive.
Personally I would still go with a converted chest freezer because the compressors on any modern freezer tend to die within 5-10 years. This means you will be regularly replacing the units so a expensive one will not have time to pay for itself.
