Whirlpool* does not market water heaters 2023
Today's 'energy smart' models from AO Smith have electronic thermostat

*Whirlpool energy smart was made by Craftmaster. 
2023

*First hour delivery numbers seem optomistic, and might represent ideal condition.
First hour is amount of usable hot water from one continuous draw. It doesn't mean hot will last an hour, it's just what happens when you start with a fully heated tank ... it delivers maximum amount of usable hot ... before it must re-heat.

This page covers 5 different models
1) Smart Electric with iComm wifi, and leak protection/ 55 gal
2) 2022  Grid Capable/ no wifi/ 55 gal
3) 2020 Energy Saver with leak protection/ no wifi/ 55 gal

4) 2020 Grid Capable/ currently only available in 80 gal ... (not shown above)
5) 2016 Energy Smart electronic water heater 40-50 gal... (not shown above)

When considering a purchase,
Remember there might be shortages of electronic repair parts.
Electronic thermostats can be replaced with ordinary thermostats and heater converted into ordinary electric water heater ... requires some wiring changes. How to convert to ordinary water heate

1) Top line model:
Smart Electric with WiFi leak protection and wifi
2022 version

Features with iComm wifi
1) Smart Electric Control Assembly, located on front of heater has push button temperature setting and status reading, plus iComm wifi options.
2) AO Smith's iComm wifi will control heater via phone app ... iComm has been available for some commercial gas heaters for several years. iComm pdf
3) It appears the heater will operate if Control Assembly is unplugged from upper thermostat, but not wifi.
4) Flash code error display to help diagnose problems Error code pdf
5) Leak detection sounds alarm .... and shuts off water to heater via wired connection to optional AO Smith water shut off valve ... if it works when needed 10 years from now.

6) 8 year tank and parts warranty is good value.
7) 92-93%  efficiency is same as any ordinary electric water heater.
8) Smart Electric Electronic upper and lower thermostats give 'more accurate temperature reading' vs ordinary mechanical thermostat, but have higher replacement cost.
9) Choice of 55-50-40 gallon tank. Tall or short models
10) Two generic 5500 watt elements for faster recovery, give maybe 7 more gallon of hot per tank vs 4500 watt elements. Requires 30 amp breaker and 10 ga wire.

11) 75 gallon first hour delivery for 55 gallon tank, 72 gal for 50 gallon tank, 63 gal first hour for 40 gallon tank ... numbers seem exagerated but might indicate thermostat setting above 130°?.
12) 3/4" Ball type brass drain valve for easy draining, flushing and clean-out.
14) Standard 100,000 BTU rated TP valve.
15) Standard hex head aluminum anode rod prevents tank from rusting. If heater rusts quickly, then turn down water softener, and try installing power anode rod in place of standard anode. This alteration might void product warranty.

16) This heater can replace any ordinary residential electric heater, must use 30 amp breaker and 10 ga wire, and set in drip pan for leak detection.
17) Residential installation. Not rated for commercial application.

These 208V-240V electric water heaters can be installed by homeowner without loss of 6 year or 10 year warranty. They do not have built-in timers, wifi, electric usage monitor, etc. All models require 10 gauge wire and 30 amp breaker.

Current Energy Smart has non-generic electronic upper thermostat, generic elements, generic aluminum hex anode, with shorter nipples on top of heater to 'reduce heat loss' and meet government energy standard, same efficiency as ordinary electric water heater (92% overall efficiency), and 6 or 10 year warranty models, both 40 and 50 gallon, tall and short, with one 55 gallon model. Difference vs ordinary electric heater is electronic thermostat gives more accurate water temperature and blinks diagnostic codes. The 10 year warranty model has additional features: a leak alarm that sounds, 5500 watt elements to increase hot water, plus display module or ESM located on front for ez temperature change, operation status, and choice of modes that might save energy. Go to current models

Energy Smart might cost more to repair than ordinary heater because of electronic thermostat vs generic thermostat.

Whirlpool energy smartElectronic thermostat
Same electronic thermostat installed on all models.
To access electronic thermostat, take off upper metal cover or display module located on side of tank.
Non-CFC foam insulation.
The insulation must be lifted, and then put back in place so thermostat reads correct temperature.
I cut off insulation to get better photo.
Diagnostic LED indicator blinks status code.  Error codes
If power is NOT turned off, the wires on element are live, but power must be ON if diagnostic code is needed. Recommend caution.
If the 10 year warranty model is installed, then code blinks on the display module located on front of tank.
If electronic heater is converted to ordinary heater, then regular thermostat can be installed in place of electronic thermostat

The lower 'thermostat' is a thermistor

The thermistor produces electric current that varies as water temperature changes. The small current is sent to upper thermostat, where the electronic thermostat switches the lower element on-off based on temperature of water in lower part of tank.

Quote from product manual:
According to the Department of Energy (DOE), since 1982 the growth in peak electricity demand has exceeded power transmission growth. This has caused more frequent blackouts and service interruptions, as well as an increase in the costly reserve capacity the power grid requires to meet higher peak demands.
The increased demand for electrical power across the nation has also led to higher peak utility costs.
Smart appliances are one way to help mitigate this problem. By using advanced digital communication technologies, smart appliances will be able to communicate with local power company or home energy management systems, and react accordingly to save energy and money.

Back of EMS Module

When contacting Whirlpool about smart-grid connections
, Whirlpool asks that you contact local electric provider.
Manual says EMS module will be 'able to communicate with local power company or home energy management systems.'

As of Jan 2012, there is no remote connection available between Whirlpool products and power company's smart-grid.

2021, ask power company about demand response program if available.
In 2021, add a meter to water heater for accurate energy tracking.

Multiple uses
Ideal for the newest energy smart with the ball-type brass drain valve
Honeywell mixing device Whirlpool manual suggests mixing valve
Why?
The newest energy smart has 5500 watt elements for higher first hour delivery.
First hour means the amount of usable hot water from a single continuous draw.
You can further increase first hour delivery by setting the thermostat higher.
The risk of high temperature water coming from tank can be solved by using a mixing valve.
For example the tank is set to 145°F, but mixing valve is set to 120°F...
... then the mixing valve adds cold water to the line...
... and maximum water temperature at any tap is safe 120°F

This means more hot water is stored inside tank so you get higher first hour ...
... without risk of scald.
