G. BACKUP HEATING WITH THE EXISTING SYSTEM OR ELECTRIC
If the GARN® unit is being added to an existing building, the existing heating system will normally be used as a backup system. Off peak electric heating is available as part of the GARN® unit to serve as a backup to the wood heating. Some utility companies offer discounted electric rates to installations using electric heat with heat storage equipment. Contact your local utility about various programs. Then contact your GARN® dealer for electric backup heating options.
