The best electric hot water heater depends on whether you need stored hot water for plumbing, on-demand hot water, or simply boiling water for drinks. The GE 18-gallon model suits buyers seeking a compact plug-and-play storage heater, while the VEVOR 12-gallon is sized for one or two outlets. For tankless options, the APUS offers higher stated flow capacity and the ThermoMate is designed for point-of-use service. The Chefman kettle is a countertop appliance, not a plumbing water heater.

GE Appliances 18-Gallon Electric Water Heater
Best for: Buyers who need a compact storage water heater that can serve a single hookup or potentially a small home, condo, or apartment. Its 18-gallon capacity is larger than the VEVOR model listed here, while its 120-volt connection may suit locations where that supply is available.
The product is described as plug and play, with an adjustable thermostat and standard 3/4-inch NPT-compatible water connections. Its compact design is intended for tight spaces such as kitchens, bathrooms, laundry rooms, cabins, garages, and sheds. The listed installation description says it connects to an existing plumbing setup and a 120-volt supply.
Why it was selected: The stated flexibility and 18-gallon storage capacity make it a useful comparison for shoppers who want a tank rather than an on-demand unit. Limitation: It stores a finite amount of heated water, and the listing does not provide a recovery rate or a detailed household-demand estimate. Confirm that the electrical supply and plumbing arrangement suit the installation.
VEVOR 12-Gallon Point-of-Use Heater
Best for: A studio, small apartment, or remote water point serving one or two outlets. VEVOR lists a 12-gallon tank and 1600-watt heating element, with uses including showers, handwashing, and dishwashing for singles or couples.
The heater has an LED display, knob control, side outlet, and 120-volt storage design. The listed features include a 20 mm foam insulation layer intended to reduce heat loss, an enamel interior, and built-in dry-heating, overheating, and overpressure protections. It also has an IPX4 waterproof rating and includes a temperature-and-pressure relief valve according to the product name.
Why it was selected: Its stated capacity and outlet range make it a direct option for localized hot-water demand rather than a large household system. The insulation and listed safety protections are useful comparison points. Limitation: The 12-gallon capacity is limited; buyers with multiple simultaneous demands should compare their expected use with the tank’s size.
APUS 27kW Electric Tankless Heater
Best for: Buyers considering a higher-output tankless unit. The product name specifies 27 kW, 240 volts, and up to 6.5 gallons per minute, with “3s instant” also stated in the listing title. Tankless designs heat water on demand rather than storing it in a reservoir.
Why it was selected: Its stated power and maximum flow make it the higher-capacity tankless comparison among the listed products. It may be worth evaluating when the goal is on-demand hot water and installation conditions can support the unit.
Limitation: The listing information provided does not specify required breaker size, wiring, or how the stated flow changes with incoming-water temperature. Do not assume the maximum flow will be available in every home. Check the installation requirements and household electrical capacity before choosing a 27 kW, 240-volt heater.
ThermoMate 8kW Point-of-Use Heater
Best for: A buyer seeking a smaller tankless unit for a point-of-use application. The listing specifies 8 kW at 240 volts, self-modulating operation, and 1.56 gallons per minute at a 35°F temperature rise.
Why it was selected: Its listed flow and temperature-rise figure give shoppers a concrete basis for comparing it with a larger tankless model. It is described as a space-saving, on-demand heater, so it may suit a specific fixture or localized hot-water need better than a storage tank.
Limitation: The stated 1.56 GPM is tied to a 35°F rise; it should not be treated as a universal flow figure for all incoming-water temperatures. It requires 240-volt service, so confirm electrical requirements and the desired hot-water flow before purchase.
Chefman 1.8-Liter Electric Kettle
Best for: People who want to boil water for tea, coffee, or other hot beverages. This is a countertop kettle, not a water heater for a shower, sink plumbing, or household hot-water supply.
The Chefman kettle has a 1.8-liter capacity and 1500-watt power rating. Its listed features include a removable lid for cleaning, a stainless steel filter, borosilicate glass, cordless serving from a plugged-in base, automatic shutoff, and boil-dry protection. The product description says it can boil water in about three minutes.
Why it was selected: It addresses the “hot water” part of the search for shoppers whose actual need is a small amount of boiled water at the counter. Limitation: Its small capacity and kettle design do not make it a substitute for a plumbing-connected storage or tankless heater.
Buying Guide: How to Choose an Electric Hot Water Heater
Do you need a plumbing heater or a kettle?
Start by identifying where hot water must be delivered. A storage tank or tankless water heater connects to plumbing and supplies fixtures. An electric kettle heats a limited volume of water for pouring and serving. The Chefman model belongs in the second category; it cannot supply a shower or sink through household plumbing.
Should you choose a tank or a tankless design?
A storage heater warms and holds a fixed volume. The GE model lists an 18-gallon tank, while VEVOR lists 12 gallons. A tank can provide stored hot water, but the available quantity is limited by capacity and replenishment. A tankless unit heats water as it flows and does not store a reservoir. Its usable flow depends on the unit’s output and the temperature rise needed.
How much capacity or flow do you need?
Estimate how many fixtures may use hot water at the same time and how long they will run. For a small space or one or two outlets, the VEVOR’s stated 12 gallons may be relevant. The GE’s 18-gallon capacity offers more storage among these two tank options. For tankless choices, compare the APUS listing’s “up to 6.5 GPM” with ThermoMate’s 1.56 GPM at a 35°F rise. These figures are not directly interchangeable because the conditions and product details differ.
What electrical supply does the heater require?
Check voltage and power before purchase. The GE and VEVOR listings specify 120 volts; the APUS and ThermoMate specify 240 volts. Do not assume that an existing outlet or circuit is suitable simply because the heater is electric. Review the manufacturer’s installation instructions and have a qualified professional assess the electrical and plumbing setup when needed.
Where will the heater be installed?
Measure the available space and consider access to plumbing connections, electrical service, and maintenance areas. The GE listing emphasizes compact installation in spaces such as kitchens, bathrooms, laundry rooms, cabins, and garages. The VEVOR is positioned for small apartments, studios, and remote water points. Tankless models can save storage space, but their electrical requirements may affect whether a location is practical.
Which safety and operating details should you compare?
Look for clearly stated protections and controls, then verify installation requirements. VEVOR lists dry-heating, overheating, and overpressure protections, an IPX4 rating, and a T&P valve in its product name. The Chefman kettle lists automatic shutoff and boil-dry protection. These features serve different appliance types and should not be treated as substitutes for correct installation or appropriate household electrical capacity.
Frequently Asked Questions
What is the best electric water heater for a small apartment?
The VEVOR 12-gallon heater is specifically described for studios and small apartments and is intended for one or two outlets. The GE 18-gallon model is another option if its larger tank and 120-volt requirements fit the space and installation.
Is a tankless electric heater always more powerful than a tank heater?
No. Tankless and storage heaters work differently, and their stated capacities use different measures. Compare a tank’s gallons with a tankless unit’s flow rate and temperature rise, then match those figures to your household’s actual demand.
Can the Chefman kettle replace an electric water heater?
No. It boils up to 1.8 liters for countertop use. It does not connect to household plumbing and is not designed to supply hot water to fixtures.
What does 1.56 GPM at a 35°F rise mean?
It is the ThermoMate’s listed flow rate under a 35°F water-temperature increase. The figure is tied to that rise; actual flow and delivered temperature can vary with incoming-water conditions.
Do 240-volt heaters need an electrical check before installation?
Yes. The APUS and ThermoMate listings specify 240 volts. Confirm the home’s electrical capacity and the manufacturer’s installation requirements before buying or installing either unit.
