When outdoor temperatures drop or a heat pump enters a defrost cycle, supplemental electric heat can help maintain indoor comfort. The MRCOOL MCAEHFD20X1BA is a heat kit that provides additional heat during extreme winter weather and can serve as backup heating during transitional seasons.
The kit provides 20kW of supplemental heating capacity and operates on a 208/230V electrical configuration. Built-in overheat protection adds a safety feature to the heating system. The MCAEHFD20X1BA works with compatible Signature Series TruInverter air handlers and supported thermostats.
A User Noted: “It’s helpful to have the extra heat available when the weather gets really cold, especially when the heat pump needs a little additional support.”
