The Wine Guardian through-the-wall unit with heater will either cool or heat the air, but it is not designed to do both at the same time. The Wine Guardian electric heat option must be specified at time of order and is installed at our factory prior to shipment.

If your wine cellar features one or more glass walls and you are close to the maximum recommended BTU/h, consider purchasing the D025 with heater. Always run complete heat load calculations before purchasing a wine cellar air conditioning unit.
