Overview
Not a tankless unit or a full-size heater, the A. O. Smith ProMax compact is a small electric tank designed for tight spots. Side connections let it slide under a counter or into a crawl space, and it runs on standard household voltage.
A small tank that fits where full heaters cannot is the reason to fit it, with plumbing and wiring on the side to save clearance. The brass drain valve resists tampering. Recovery rate, temperature limits and warranty are not listed.
Who it's for
Point-of-use jobs, small offices and garage sinks are its target. Families wanting whole-house supply need a far larger tank.
Pros and cons
- Fits under a counter
- Side-mounted connections save space
- Brass drain valve
- Runs on household voltage
- Small capacity for whole-house use
- Recovery rate not listed
- Warranty not stated
- Battery power listing looks wrong
Performance notes
Hot water supply depends on tank size and the element's wattage, so long draws empty the stored hot water before it reheats. Side connections cut the height needed above the unit. Incoming water temperature affects how fast it recovers.
