Is the ENT-50 130 right for your replacement?
The A.O. Smith ENT-50 130 is a conventional electric storage-tank option for a home considering a 50-gallon replacement. At Water Heating Experts, we start with how your current heater performs: whether you run out during back-to-back showers, how often appliances overlap and whether your hot-water needs have changed.
A matching gallon label does not guarantee a matching installation. We review the available height and width, access to the heater, existing water connections and electrical supply before recommending equipment. If your current heater is in an attic or another difficult location, we can also discuss whether moving it to the garage makes sense for your project.
Hot-water delivery and electrical requirements
A.O. Smith lists a 62-gallon first-hour rating for this model. That is a standardized delivery rating, not the amount physically stored in the tank or a promise of uninterrupted shower time. The listed configuration uses 240-volt power and two 4,500-watt elements; the manufacturer lists a maximum input of 4,500 watts, not 9,000 watts.
We confirm the supplied unit’s data plate and existing circuit as part of equipment selection. If lower operating energy use is your main priority, compare the installation requirements of a hybrid heat-pump water heater before settling on a conventional electric tank.
What affects the installed price?
The estimate depends on more than the heater. Access, removal of the old unit, changes to piping or shutoff valves, drainage, expansion control and any necessary electrical work can affect the scope. We review the installation before confirming equipment, availability and price.
For a useful starting point, send a clear photo of the existing model label and a wider photo showing the heater, connections and surrounding space. Tell us about any leaks, hot-water shortages or planned changes in location.
Warranty and ongoing care
A.O. Smith lists a six-year limited tank and parts warranty for this model, subject to its written terms. Manufacturer coverage and installation labor are separate; the product warranty should not be read as six years of free service calls or replacement labor. We explain the applicable installation coverage with your estimate.
Keep the model and serial number, installation paperwork and maintenance records. Follow the manufacturer’s care instructions for the equipment and water conditions. Tank-protection features do not eliminate the need for maintenance.

ENT-50 130 questions
Why is this called a 50-gallon heater if its rated storage is 46 gallons?
A.O. Smith identifies the model as 50 gallons nominal and lists 46 gallons of rated storage. We show both so you can compare models using the same type of measurement.
Will it fit where my current 50-gallon heater sits?
We need to check the actual space and connections. The tank dimensions alone do not include every access or service requirement, and another 50-gallon model may have a different shape.
Is this a tankless or heat-pump water heater?
No. The ENT-50 130 is an electric resistance storage-tank model. We can help compare other equipment types when your priorities include space, hot-water delivery or operating costs.
Can you install it in Palm Beach Gardens or Jupiter?
