The Alpine branded heater coils can be manufactured either by Goodman or by Warren. They are designed to install in and work perfectly with the Goodman models that they are accessorized to. 

This 240 volt heater coil can be added to a Goodman self contained air conditioner to provide winter-time heating capabilities or in a self contained heatpump as an auxilary heat source.

Produces 51,150 BTUs of heat.

Controlled by sequencers for optimum temperature balance. Completely assembled and tested. Built-in overcurrent protection on all units as indicated in electrical data chart (see spec sheet). Multiple branch circuit capability. High temperature limit controls for safe operation. Plug-in wiring harness for easy installation into self contained air conditioners and heat pumps. Rust-resistant nickel chromium heat elements.
If you are installing the heater coil in a packaged air conditioner or heat pump, another circuit in addition to the heater coil circuit(s) is still required to operate the packaged unit
Depending on the heater coil size being installed, one or two circuits to the heater coil will be necessary (see the Specifications tab above for quantity and amperage of circuits required for this heater coil.) At your home's circuit panel, individual 220 volt double-pole circuit breakers are required for each circuit.
