Description
This MRCOOL 5 kW electric heat kit is made for Signature Series R-454B Multiposition Air Handlers. It ships as a single field-installed assembly measuring 14.13" D x 9.25" H x 10.38" W gross.
Highlights
- 5 kW electric heating element adds supplemental heat capacity to the air handler it is installed in.
- Built specifically for Signature Series R-454B Multiposition air handlers, so the fit and connections are matched.
- Compact 14.13" D x 9.25" H x 10.38" W gross size for installation inside the multi-position cabinet.
- Genuine MRCOOL accessory rather than a universal aftermarket part.
Details
Avermont Direct is an authorized MRCOOL dealer, and this heat kit ships as genuine MRCOOL equipment. On a heat-pump system, a 5 kW kit like this one supplies supplemental electric heat during cold weather, when the outdoor unit alone cannot meet the heating load. It is backed by the manufacturer's warranty — see product documentation for full terms.
