Through-the-Wall Conditioning Units

What is a ‘through-the-wall’ air conditioning system?

A through-the-wall air conditioner, also known as a through-the-wall wine room cooling unit in this context, is a self-contained ductless cooling system designed for wine cellars. Unlike central air conditioning systems or split systems, through-the-wall units do not require duct-work for installation. Instead, they are mounted directly onto an interior wall, typically in a utility room adjacent to the wine cellar. There are some models that can be fitted to an exterior wall, yet they are more expensive. If this is what you’re looking for, look out for systems that have a ‘frost belt’.

Benefits of Through-the-Wall Air Conditioners:

  1. No Duct-work Required: These units eliminate the need for complicated duct-work installations, making them simpler and more cost-effective to install.

  2. Ease of Installation: They can be installed by a knowledgeable individual without the need for professional HVAC-R technicians, reducing installation costs.

  3. Cost-Effective: Through-the-wall units are generally cheaper to purchase and install compared to ducted or split systems, making them an affordable option for wine cellar cooling.

  4. Temperature and Humidity Control: These units provide precise temperature and humidity control, creating optimal conditions for wine storage.

Negatives of Through-the-Wall Air Conditioners:

  1. Noise: Some units may produce noise during operation, which can be a concern if the wine cellar is located near a living area or frequently used space.

  2. Aesthetic Appearance: They usually protrude from the wall, detracting from the overall aesthetic of the wine cellar and making them less visually appealing.

  3. Location Limitations: Installation requires a wall capable of withstanding high temperatures, enough space to allow airflow and the correct insulation, which may limit placement options in certain environments.

General Uses of Through-the-Wall Air Conditioners:

Through-the-wall air conditioners are well-suited for small to medium-sized home wine cellars, providing efficient cooling and humidity control without the need for extensive duct-work. They are ideal for homeowners seeking a cost-effective cooling solution for their wine storage needs. However, for larger wine cellars or commercial applications, alternative cooling solutions may be necessary to ensure adequate temperature regulation and efficiency.

Is a through-the-wall conditioning system right for you?

Before deciding if a through-the-wall air conditioning system is right for you, there are several key steps you should take:

  1. Determine the Purpose of Your Wine Cellar: Consider whether your wine cellar is primarily for storing and ageing wine or if you also want to use it for entertaining guests and showcasing your collections. Determine the quantity and types of wine you plan to store, as well as your preferences for racks and storage options.

  2. Identify the Location: Choose a location in your home for the wine cellar that is cool and humid, as these conditions are optimal for wine storage. Aim for a temperature range of approximately 13°C - 14°C and humidity levels of 55% - 75%. Keep in mind that higher surrounding temperatures may require a larger cooling system, potentially increasing costs.

  3. Determine the Size of the Wine Cellar: Estimate the size of your wine cellar based on the number of bottles you plan to store and any additional features, such as a centre island. Through-the-wall cooling units are well-suited to smaller wine cellars ranging from approximately 25m³ to 85m³.

  4. Consider your Budget: Through-the-wall systems are generally the more budget-friendly option, starting at £2929 for a Fondis Winemaster C25 cooling only unit.

  5. Add Critical Components: Ensure your wine cellar is properly insulated to maintain temperature and humidity levels. Consider using R-values of R19 for walls and R30 for the ceiling, and add vapour and moisture barriers to prevent water or moisture infiltration. Invest in an insulated exterior or solid interior door to minimise air exchange.

  6. Invest in a Quality Cooling System: Select a reputable wine cellar cooling system that suits your needs and budget. Look for brands like Fondis, Friax, or Thermocold known for their reliability and durability.

By following these steps and considering factors such as location, size, and components, you can make an informed decision about whether a through-the-wall air conditioning system is the right choice for your wine cellar.
