6 Through-The-Wall Wine Cellar Cooling Units

How to Build a Wine Cellar

Thinking of having your own wine cellar in your home? We listed the things you need to consider when you are planning to construct your own wine cellar for your place.

We already know what self-contained, ducted, and ductless split wine cellar cooling units, but what are through-the-wall cooling systems? Through-the-wall cooling systems are basically self-contained which are compared to air conditioners that cannot vent outside. They can only vent into an adjacent room bigger than the maximum cooling capacity of the specific unit. 

The upside of getting a through-the-wall wine cellar cooling unit is you do not have to hire a professional HVAC-R technician to install them. A handy person who is knowledgeable about air conditioning installation will do.

Why do you Need a Wine Cellar?

First and foremost, you need to think about what is the main purpose of your wine cellar. Is it for storing and aging wine or do you want to entertain your guests and showcase your collections? How many bottles and what types of wine do you want to store in it? What kind of racks do you want --- the traditional wood racks or contemporary metal racks? 

If you want to entertain guests in your wine cellar, you might want to consider having a center island. If you have the budget and space, you can add your own personality or touch to your wine cellars.

Determine the Size of the Wine Cellar

This is step #2. In order to determine the size of your wine cellar, you need to know how many bottles you wish to store, if you have other things, like a center island, you want to add, and how much space you can devote to your cellar. 

Identify the Location

The most important part of planning for your own wine cellar for your home is its location. Basically, you can have your cellar anywhere in your home but the location you choose will have an impact on the cost you spend in maintaining your cellar.

Wine cellars should be places in the coolest and most humid part of your home. When the temperature is closer to 55°F - 58°F and the humidity to 55% - 75% the smaller the size of the cooling system you will need. Which means less money you will need to spend. 

The heat surrounding your wine cellar will affect it. If the surrounding environment is above 65°, you will need to get a much larger cooling system which is more expensive, to maintain the ideal temperature inside your wine cellar.

Add 3 Critical Components

Let's now talk about the 3 most important components of a wine cellar to properly store and age your wine.

Insulation

It's a great idea to insulate the ceiling and walls of your wine cellars. You can save some bucks when your cellar is properly insulated. We recommend a minimum of R19 batt insulation for your 2x6 walls and R30 for the ceiling, supposing you have 2x10 joists. 

If your cellar is located in the basement, you do not have to insulate your floors but otherwise --- for example, a closet or if it is on the second floor of your home --- it will be wise to insulate the joist bays as well. You can also add some thick carpeting to help with the insulation.

If you are converting a closet or an existing room into a wine cellar, you can also consider blowing insulation between the joist bays.

Vapor & Moisture Barrier

Vapor and moisture barriers are materials designed to prevent water or moisture from getting pass through the barriers. These are needed in your wine cellar to make sure you get the desired humidity and temperature to properly store and age your wine. The most common vapor barrier used for wine cellars is 6 mil polyethylene sheeting or Visqueen. It is wrapped around your entire cellar on the outside of the insulation.

The Door

Not just any door will do. You will need an insulated exterior door or a solid interior door to keep warm air from going in your wine cellar and cool air from escaping. If you are going for a solid door, you need to add a little weather stripping around the jamb and at the bottom sweep.

Airtight Seal

It is necessary that when the door is closed, no air should come in and out of your wine cellar. 

Investing in a Wine Cellar Cooling System

Select a wine cellar cooling system that can last for a long time and made by a known company to make sure you get what you paid for. Just like companies like Breezaire and WhisperKOOL!

Wine Racks

There are various wine racks you can have in your wine cellar but here are 4 popular types:

Individual Bottle Storage

This type cradles your bottles individually in their own cell, either single or double deep. The great part of having individual bottle storage is that the cradles can have various sizes perfect for storing various types and sizes of wines. It can be made from wood or metal, depending on your preference.

Diamond Bin Storage

If your aim is to store or age wines in bulk, diamond bins are for you. They are very flexible and can accommodate various-sized wine bottles. This type of rack is ideal for long storage or aging of wine because it will be difficult to access the wines at the bottom part. Careful and gentle handling is needed if you choose to store your wine in this type of rack.

Case Storage

This type of rack lets you store your wine in its original cases or boxes. There are wood and cardboard cases. Wood cases are wider and shorter while cardboard cases are narrower but taller. It is also great to have sliding shelves to easily access your wine.

Tabletops

Tabletops offer convenient and attractive cases great for opening and pouring wine. It can be made from wood or stone surfaces. This type of rack is great for displaying your wine and accessories.

Best Through-the-Wall Wine Cellar Cooling Systems

Through-the-wall wine cellar cooling units are great if you are looking for more affordable but effective cooling systems for your wine cellar. This type is also ideal for smaller wine cellars. They are very easy to install in a standard sheetrock wall.

However, many people with bigger and spacious wine cellar prefer ducted and split ones because they are quieter. Venting through-the-wall units into real living spaces are not ideal because they are louder.

If you can't have a wine cellar in your home, it might be a great idea to have a wine cooler instead.
