Cellar Insulation - walls, ceiling, floor. If your cellar is constructed with glass, or has uninsulated walls, or does not have a vapor barrier, the thermal load will be much higher than what's shown in the table. In this case, please visit our Thermal Load Worksheet to request a customized calculation for your cellar.

Cells shaded blue indicate loads that exceed the capacity of the cooling units shown in this table.

Each of our cooling units includes sizing guidelines that are based on R19 insulation throughout the cellar and 85°F peak ambient temperatures outside the cellar. To find the BTUH output for the 1800XTSr cooling unit at 55°F and 60°F, and the thermal loads for various-size cellars, refer to the table. In order to maintain your desired cellar temperature, the cooling unit's BTUH output (at 55°F or 60°F inside the cellar) must be greater than the load of your cellar, as shown in the table.
