Pack Your Freezer – Daily Financial Tip

By , April 26th, 2006 | 10 Comments »

pack your freezer - hear sinking and freezer blockingUnlike your refrigerator, your freezer runs more efficiently when it’s tightly packed. That means if your freezer isn’t completely full, you should place something inside the freezer to fill up the empty space and that is exactly what we’re going to do today.

One way to accomplish this by placing bottles of water in your freezer when it isn’t full. This is referred to as “heat sinking.” When the freezer shuts off, the the frozen bottles will help keep the food frozen. The frozen bottles will also slow down the natural heat transfer between the freezer walls and the food meaning that the freezer doesn’t have to power on again as quickly as if there weren’t there. These frozen water bottles can also help in a number of other ways.

  • As mentioned above, they will help your freezer run more efficiently by making sure it’s always full.
  • If for some reason the power happens to go out, the frozen water bottles will help preserve the food in the freezer longer than if they weren’t there.
  • After you go shopping and need to remove the frozen water bottles from the freezer to make room for food you purchased, you can place them in your refrigerator. They will help cool and reduce the cost of running your refrigerator.
  • In the summer the frozen water bottles can also be used to help cool ice-chests when not needed in the freezer.

    When filling your freezer with water bottles, remember to not fill the bottles completely full when placing them in the freezer. Water expands about 10% and you don’t want the bottles bursting in your freezer.

    The other method that can be used is called “freezer blocking.” The concept is the same as filling the freezer with water bottles, but this time you use boxes filled with insulation. As with the water bottles, less electricity will be required to freeze the food since there is less air in the freezer and thus the freezer won’t have to work as hard.

    For the boxes, you can use any type of insulation to fill them – regular household fiberglass wall insulation will work just fine which is fairly inexpensive and easily purchased at any home improvement store. Another options would be using shipping and packaging insulating peanuts. Try to get a variety of box sizes as this will make filling the freezer much easier. Once the boxes are filled with insulation, you’ll want to tape them shut since you don’t want the insulating material mixing with your food.

    Whichever of the two methods you choose, you’ll want to place the insulated boxes or water bottles in the open spaces on either side of the food and not on top. Placing it on top will make it much more difficult to reach the food that you want when opening the freezer and in shuffling everything around, you’ll likely leave the freezer door open longer which will waste energy. Placing the packing material on either side will allow you to get to your food quickly without moving everything all around.

    By taking the time to make sure that your freezer is packed tight, you’ll ensure that it is running as efficiently as possible and you are saving money.

      This does work well. I would like to add 2 additional comments on this.

      1. Use old bleach bottles if you can for freezing the water in. Often times milk and water bottles can split at the seams. The bleach bottles are much sturdier.

      2. Also check with some moving and storage facilities. They sell off their old packing blankets very cheaply. If you lose power cover the freezer (except the motor area) with the blanket(s). This will help the freezer to insulate itself from warming conditions outside. When not in use just put the blankets in a box on top of the freezer in order to locate easily.

      Well, after I go shopping, the fridge is packed as well. Damn kids eat too much.

      Thank you for all the good tips. I may have missed it but have you published tips for the best way of getting rid of old cellphones ?.

    • Maira,

      Many stores, such as the Body Shop, will hold annual cell phone collection drives. You can start up one yourself. Check out the following link. http://www.shelteralliance.net/cell-phone-donations/index.cfm#

      If you collect 20 phones, they’ll pay for shipping. If not, click on the donate less than 20 button. You’ll have to pay for shipping, but they’ll take care of recycling it for you.

      I haven’t, but will put that on my list. If the model is fairly recent, you can sell them on ebay fairly easy and if you don7t want to go through that trouble, you can also get paid for them as well as the above mentioned donation possibility.

      Lol, great tip. I never thought of saving money like that. My freezer is generally pretty full most of the time though, I buy a couple of bags of fresh pasta from my local supermarket when it’s on special and just throw them in the freezer. When it’s on special it works out less expensive than dried pasta, cooks quicker and now I guess, saves me electricity too!
