No, but close to it.
In regards to just the heating of the water, Tank-type, and tank-less, electric water heaters are about 99% efficient* because the heating elements are immersed in water, and little energy is wasted between heat source and water.
However, all tank-type water heaters loose heat from their reservoirs (tanks). This heat loss lowers the overall efficiency.
Most electric heaters fall between 90-95% total. This is the number that is usually reported by the manufacturers.
* Efficiency is not the same as cost savings. For example electric heaters have higher efficiency, but cost more to operate than same-size gas water heater. Also tankless gas heaters, gas water heaters with blowers, and gas heaters with high recovery may claim higher efficiency, but they consume more fuel per hour of operation.
Additional Information:
Efficiency of heating elements does not consider inefficiencies in production, transmission, refining, and delivery of electricity. Estimates say coal-fired power plants waste half the energy of coal during electric generation. However hydroelectric power plants are very efficient.
Tank-type gas water heaters are 69% efficient, since hot combustion gas escapes out the flue after hydrogen content of fuel is burned. This number does not consider inefficiencies during production, transmission, refining, and delivery of gas.
Tank-less gas water heaters are 79% efficient, but tank-less burn more gas per gallon of hot water than tank-type heaters. Hot combustion gasses are released out the flue and are not actively recycled without slowing combustion which turns off unit. Newer type tank-less with blower recycles heat into a tank operate at 96% efficiency, and are made for oversize consumption of both energy and hot water.
High efficiency tank-type gas heaters operate at 96% efficiency by using blowers to circulate hot combustion gas through coiled tube located inside tank. Same amount of combustion gas is released since only heat is recycled. The use of electric blower affects overall cost.
Environmental efficiency: Electric water heater does not release CO2 at each home, instead CO2 is localized at power plant. Gas water heaters release CO2 at each home which factor in environmental efficiency.
Efficiency of all gas water heaters falls and cannot be fully restored if untreated hard water deposits sediment over heat transfer surface. Generally, gas heaters exposed to hard water require softener which affects overall efficiency.
Efficiency of tank-type electric water heater remains at 99% until sediment reaches element, causing element to burn out. Full 99% efficiency is restored by cleaning out tank and replacing element. Generally, tank-type electric heater does not require water softener.
Downsizing water heater, reducing consumption, selecting water heater with fewer parts, reading the manual, and draining tank each 6 months to avoid sediment are key to saving energy.
No, an electric hot water heater is not 100 percent efficient. Some of the energy can be lost through heat dissipation or during the heating process, resulting in less than 100 percent efficiency.

What is electric water heater which used in house?
An electric water heater in a hot tank is called an immersion heater and many of those run at 3 kW with a thermostat to control the max temperature. Power showers use a type of water heater that heats the water at the point where it is used, without a tank. They run at 6-8 kW and are also controlled by a thermostat.
Who makes General Electric water heater?
Rheem
What is the difference between an electric mobile home hot water heater vs a regular electric hot water heater?
Not much actually,a Mobile Home water Heater has the water connections going into the side where as a Regular Water Heater has the connections at the top. So if you have enough room above a mobile home water heater you can install a regular water heater no problem.However a lot of mobile homes do not have room above the water heater so your forced to use a Mobile Home water heater instead. Which usually costs about a hundred more than a regular one.
Why does my gas water heater need to be hooked up to a 30 amp breaker with 220 volts?
A gas water heater doesn't use electricity to heat water like an electric water heater does. The electrical connection is typically for powering the ignition system or other electronic components on the gas water heater. The 30 amp breaker with 220 volts is required to safely supply power to these components.
I want to go on vacation and turn off my electric water heater using the switch on my fuse box My question is is it bad for an electric water heater for the electric power to be cut off?
No, turning off the electric power to your water heater temporarily should not harm it. Just remember to turn it back on when you return to avoid issues like freezing pipes or electrical problems.
Is a tankless electric water heater more efficient than a gas water heater?
Normally NO
What is the most efficient method Water heater?
One of the most energy efficient water heating methods is the heat pump water heater. This method is proven to be two times more efficient over the standard electric water heater.
Electric Hot Water Heater?

What are the advantages of the GE water heater?
The advantages of the GE water heater are that it is more energy efficient and is more generally environmentally friendly as it lowers the amount of Carbon Dioxide emissions. It will also lower electric heating and water costs for your home.
Water Heaters ?
Water heaters are devices designed to heat water for domestic, commercial, or industrial use. They come in various types and are chosen based on energy efficiency, cost, space, and specific needs. Here's a breakdown of water heaters: Types of Water Heaters Storage Water Heaters How It Works: Heats water and stores it in a tank until needed. Key Features: Continuous supply until the tank is empty. Sizes vary (30 to 100+ liters). Pros: Affordable upfront cost. Easy to install. Cons: Limited hot water supply. Higher energy consumption due to standby heat loss. Tankless (On-Demand) Water Heaters How It Works: Heats water directly as it flows through the unit. Key Features: No storage tank. Compact design. Pros: Energy efficient (no standby heat loss). Provides endless hot water. Cons: Higher upfront cost. Limited flow rate; may struggle with simultaneous high-demand usage. Heat Pump Water Heaters (Hybrid) How It Works: Uses electricity to transfer heat from the air or ground to water. Key Features: Energy-efficient alternative to electric heaters. Pros: Environmentally friendly. Long-term energy savings. Cons: High initial cost. Slower heating process. Solar Water Heaters How It Works: Uses solar panels to capture sunlight, heating water stored in a tank. Key Features: Requires sunlight and a backup system for cloudy days. Pros: Renewable energy source. Minimal operating costs. Cons: High installation cost. Location dependent. Electric Water Heaters How It Works: Uses electrical heating elements to heat water in a tank or on demand. Key Features: Common in urban areas. Pros: Easy installation. Low upfront cost. Cons: Higher operating costs due to electricity prices. Gas Water Heaters How It Works: Burns natural gas or propane to heat water. Key Features: Available as storage or tankless models. Pros: Lower operating costs compared to electric models. Heats water quickly. Cons: Requires gas line installation. Potential for gas leaks. Factors to Consider When Choosing a Water Heater Energy Source: Electric, gas, solar, or hybrid. Capacity: Choose based on household size and water demand. Efficiency: Look for energy ratings and technology that minimizes operating costs. Space Availability: Tankless models save space, while storage heaters require more room. Budget: Consider upfront and long-term costs. Maintenance: Some types require more upkeep, like descaling for hard water areas. Would you like advice on selecting a water heater for a specific use or location?
