Overview

A buyer with an under-counter niche or a crawl space can fit this A. O. Smith ProMax Specialty Electric water heater, which has plumbing and electrical connections on the side. The unit holds a modest volume, and the drain valve is tamper-resistant brass.

Side connections and a compact body make it workable where a standard tank will not fit, which is the reason to buy it. The limitation is that electrical ratings, recovery data and warranty are not listed.

Who it's for

Homeowners replacing or adding a compact heater in a cramped area will find the side connections help. Large families and anyone who wants listed wattage, voltage and warranty figures should look at a bigger or better documented model.

Pros and cons

Pros
  • Compact space-saving design
  • Tamper-resistant brass drain valve
  • Energy-efficient feature listed
Cons
  • Voltage and wattage not listed
  • Modest tank capacity
  • Warranty not given

Performance notes

Capacity and element rating together set how much hot water is available and how fast it recovers, and the electrical side is not documented here. Side connections shorten the plumbing run in tight spaces. The tamper-resistant brass valve drains the tank for service.
