This through-the-wall wine cellar cooling system with a heater is ideal for small residential wine cellars and wine cabinets. WG15H units are best suited for rooms up to 20 m3 with limited glass and very good insulation. You should select the version with the heater if the ambient air will be lower than 55 °F or 12 °C, such as in some second homes that are not heated year round or in some cool climates.  This unit is easy to install and can be installed without the support of a contractor. The max capacity of the WG15H is 0.22 Kilowatts. Note: not rated for exterior use.

The Wine Guardian heater option acts to warm the air entering the wine cellar in order to maintain a constant set point.
The electric heat option includes the following:
-500-watt integral heater
-Thermal overload protection device and controls

The Wine Guardian WG15 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.

The WG15 can be equipped with other options and accessories including remote sensors.
