Selection note: For replacement, match the wattage and voltage on the existing unit's nameplate. For new installations, use the heater rating specified on the enclosure's data sheet, and consider the next capacity up for exposed, high-wind, or low-design-temperature sites. Confirm the branch circuit is rated for the unit's full-load amperage.
