Auxiliary heat, often called "heat strips," is a backup electric heating element used in Ducted Heat Pump Systems. It provides extra warmth during the coldest days when the heat pump alone might struggle to keep up. While our Hyper Heat mini-splits rarely need backup, it is a common addition for whole-home central units. We offer these Heat Kits as an optional accessory for our larger Central Condensers. It ensures that your home stays warm no matter how far the temperature drops. You can find technical wiring info for these in the Technical Data section. Auxiliary heat is a great insurance policy for homeowners in the coldest northern climates. It’s all about providing year-round peace of mind.
