All the parts and pieces finally fell into place for us to setup our Chest Freezer as a Fridge. For those new to this thread, we had purchased a new Energy Star Chest Freezer from Lowes, an external Thermostat Control from Amazon, and put them together to have a super-efficient refrigerator.
We hooked the thermostat up in about 5 minutes. It consisted of unwinding the semi-stiff metal thermostat probe wire, running it up over the back of the freezer, down into the freezer, and across the back. We hid ours underneath a built-in rail used for hanging baskets, so it’s not visible or in danger of getting damaged.
Once installed, we simply turned the built-in thermostat to it’s max setting, then plugged the freezer into the external thermostat, and then the external thermostat into the wall. The Johnson Controls Thermostat’s plug has a female receptical for the freezer to plug into.
It ran for about 3o minutes to reach our desired temperature of about 37℉, then shut off the power. From then on, it’s run less than 10 minutes per hour.
This AM, with the Kill-A-Watt attached for 12 hours, the unit has used .22 kWh of power. That’s quite impressive and at today’s prices equals a few nickels over $15 for the year if this stays consistent! That’s a whopping big difference from our old fridge which cost $115-$120/yr! We had thought that we’d save up to 95% from what we’ve seen others achieve and we’re currently realizing a savings of 87%. That’s acceptable 😉
How does it work for the family?
So far, everyone really digs the setup. At 14.5 cubit feet, it’s quite a lot of space, it has way more room in it than our previous fridge, and everything is very easy to get to, except by our 4-yr old, which is a bonus since we are always telling her to get out of the fridge! We could literally store twice as much food as previous and still pay 80% less for the power. Not bad, eh? Looking and reaching top-down into the fridge is nice too. We have a bird’s eye view of everything and it’s all easy to reach. Hopefully the pictures give some idea of the setup.
Is it worth it?
A few people have commented that this is not much of a savings. If you just bought a brand-new Energy Star fridge, that might be the case. I wouldn’t go this route had we had a new, efficient fridge (at least not yet). However, if you’re in need of a new fridge, consider this for a minute.
|New Energy Star Fridge||New Chest Freezer as Fridge|
|Cost of Unit||$900||$450**|
|Electric Cost 5yr.||$275||$75|
The above prices for the fridge are based on what we’ve seen available in the size range that we would need. **Price includes extended warranty of 4 years and price of thermostat!
That should put things into perspective. Perhaps some people don’t care about saving $750, but we do! Further, our savings will continue year after year. So if you already need a new refrigerator, consider this option, otherwise, find another way to save $30-50/yr.
