If you are looking for a 38-gallon short electric water heater, the closest listed options are three 40-gallon short GE models; none of the products provided is an exact 38-gallon match. The GE models suit households needing a compact tank-style heater, while the two much smaller units are point-of-use alternatives—not replacements for a whole-home tank. Compare capacity, first-hour delivery, electrical requirements, and available space before choosing.

GE Smart 40-Gallon Short With Wi-Fi
Best for: Buyers who want a short tank-style heater with remote monitoring and controls. This model is a 40-gallon option rather than an exact 38-gallon unit, making it a close capacity alternative among the supplied products.
Listed features include built-in Wi-Fi through SmartHQ, temperature adjustment, tank hot-water monitoring, vacation schedules, and notifications. The product listing identifies a 10-year warranty and a 65-gallon first-hour rating. GE describes its capacity as a true 40 gallons compared with competitive electric steel tanks based on DOE-rated gallon capacity.
Why it was selected: It combines a short-format tank with connected controls and the highest listed first-hour delivery among these tank models. Confirm dimensions and installation requirements before purchase; the provided details do not state the unit’s measurements.
GE Smart 40-Gallon Short, 5500W
Best for: Shoppers seeking a connected 40-gallon short heater who want the listing’s stated 12-year warranty term. It is not a 38-gallon model, but it is one of the closest tank-style choices provided.
The listed features include built-in SmartHQ Wi-Fi, remote temperature adjustment, an estimate of hot water remaining in the tank, vacation scheduling, and notifications. Its stated first-hour rating is 65 gallons, and GE describes it as holding a true 40 gallons relative to competitive electric steel tanks by DOE-rated capacity.
Why it was selected: It offers the same stated first-hour delivery and smart features as the other GE smart option, with a different warranty term identified in its product name. Check that the home’s electrical service and installation space meet the product requirements; detailed installation specifications were not provided here.
GE 40-Gallon Short, 4500W
Best for: Households of two to four people looking for a conventional short tank and a stated 4500W heating setup. The listing gives a 63-gallon first-hour rating and identifies two 4500W elements operating at 240V and requiring 25 amps.
Why it was selected: Its listed household guidance and electrical details make it easier to compare with the smart GE models. It may suit buyers who do not need Wi-Fi features and prioritize the stated tank capacity and first-hour delivery.
Limitation: Its listed first-hour rating is two gallons below the 65-gallon ratings of the two smart models. Verify the electrical and space requirements for the specific installation.
KENUOS 2.5-Gallon Mini Tank
Best for: A sink or limited point-of-use application where a small tank is appropriate. The product name lists a 2.5-gallon capacity, digital display, 120V power, and 1500W rating.
Why it was selected: It is a compact electric tank alternative for localized hot-water needs when a whole-home 40-gallon tank is not the intended use. The name also identifies an updated pressure-release valve.
Limitation: At 2.5 gallons, it is not a substitute for a 38- or 40-gallon household water heater. Choose it only if its small capacity matches the intended use.
ThermoMate 3500W Tankless Mini Heater
Best for: Buyers seeking a compact on-demand unit for a kitchen or bathroom sink rather than a whole-home storage tank. The product name specifies 120V, 29.2 amps, 3500W, and a temperature display.
Why it was selected: It offers a different point-of-use approach from the 2.5-gallon mini tank: it heats water on demand rather than storing a stated tank volume. The listing also describes it as ETL certified.
Limitation: It is not a 38-gallon short water heater. The supplied details do not give flow-rate or temperature-rise figures, so confirm performance suitability for the intended faucet before buying.
Buying Guide: How to Choose a Short Electric Water Heater
Is a 40-gallon model close enough to 38 gallons?
These listings do not include an exact 38-gallon short tank. The three GE models are 40-gallon short heaters, which may be worth comparing if you can accommodate their actual dimensions and capacity. Do not assume that “short” guarantees a fit: measure the installation area and verify the manufacturer’s specifications.
How should I compare hot-water output?
Use the first-hour rating as one comparison point, not as the tank’s storage capacity. The two smart GE models list 65 gallons in the first hour, while the standard GE model lists 63 gallons. Household demand, incoming water conditions, and usage timing also affect whether a heater meets daily needs.
Should I choose Wi-Fi controls?
Choose a smart model if remote temperature adjustment, tank hot-water monitoring, vacation schedules, and notifications are useful to you. Choose the non-smart GE option if those listed connected features are not a priority and its stated electrical setup fits your installation.
What electrical details should I verify?
Compare the heater’s voltage, wattage, amperage, and required circuit with the home’s existing electrical service. The provided GE specifications identify 240V for the smart models and 240V with 25 amps for the 4500W model. Have a qualified professional confirm installation requirements where needed.
