Nobody wants to use more energy than is necessary because energy is expensive. Refrigerators are some of the worst culprits when it comes to using a lot of energy in the home, and kegerators fall into this category. Thankfully you can keep the cost of running one down if you know what to do.
Keeping your kegerator running as efficiently as possible is the key to keeping your costs down. You need to make sure that your beer keg dispenser isn’t working any harder than absolutely necessary.
Like most machinery, refrigerators give off heat as they are running. If they are enclosed in a space, the heat from the back and sides can’t escape. This can lead to the keg fridge overheating, which means it will work much harder than it has to, thus using more energy. You will want to try to find a spot for it that will keep it out of the way, but also giving it some breathing room. You’ll still be able to use mini keg tap handles with them no matter where you keep them.
The best place to keep your kegerator, or any other coolers for that matter, would be the basement or cellar. Underground rooms tend to have a constant temperature which is ideal for helping to keep your kegerator running efficiently.
Another way to keep it efficient is to open it as little as possible. You shouldn’t have to open it often since kegerators are usually tapped. Switching out kegs, hooking up kegs once the beer settles, and cleaning everything should be the only reasons for the fridge to be opened.
You may want to invest in other keg accessories to help keep your home kegerator in tip-top shape. Keep a refrigerator thermometer in your keg fridge as well. This will ensure that it stays at the correct temperature. The generally recommended temperature is about 38 degrees. If you notice that your keg fridge is getting colder than this, you can modify it as needed. Getting too cold isn’t good for your beer, and also costs more money, so it’s bad all around!
