BTUH Rating


The BTU/h value shown here is a theoretical number. There are often circumstances under which a cellar design may require a larger unit due to variables not accounted for in the formula. For example, these variables could be building materials (such as glass, stone, concrete, etc.) that do not offer the insulation capacity required to maintain the optimal cellar environment. We recommend purchasing a unit with a larger capacity to compensate for these unaccounted-for variables. An undersized unit can lead to premature failure and will most likely prevent the cellar from reaching your desired temperature.

24V Thermostat Conversion Kit

Introducing our new 24-volt thermostat conversion kit for WhisperKOOL split systems!

Utilize industry-leading technology from major manufacturers to monitor the environment of your cellar. (See individual thermostat manufacturers’ websites for details.)

  • Connect your thermostat to Wi‑Fi to control the temperature from your phone, tablet, or laptop.
  • Monitor run time and energy usage.
  • Set alarm notifications.
  • View your cellar conditions from your mobile device.

The use of the 24-volt thermostat conversion kit eliminates the thermostat normally included with the system and allows your contractor to select, purchase and install the thermostat technology of your choice, including but not limited to Nest, Ecobee, and Honeywell.

By selecting the 24V Thermostat Conversion Kit, you have acknowledged that the system will not be built with the standard WhisperKOOL control or liquid measuring bottle probe. You will have to source and purchase your own 24V thermostat to run the equipment.
