Storage tank water heaters are the most common type of water heater. Inexpensive and widely available in a variety of sizes. Cold water runs into an insulated holding tank where an electrical element heats the water. The water stays hot in the tank until you draw it out through the house’s plumbing system. Cold water enters the tank, as needed, where the heating cycle repeats.
Water heating systems are the second biggest user of electricity in the home, accounting for an average of 18 percent of electricity costs
For electric heaters, The amount of electricity used by an electric water heater depends on the size of the water tank, the amount of water used, the temperature setting of the water heater, and whether the tank is insulated.
Tanks now have to be better insulated to minimize heat loss. If your existing tank water heater is very old expect your next tank to be larger in size by at least 2” in height and 2” in diameter.
Almost every home has electricity, but not all homes have access to natural gas.
Electric heaters are easier to install and are generally safer since they don't have any fuel that could leak or explode and have no combustible byproducts.
Electricity is more expensive than gas, yet Electric tank heaters operate more efficiently than gas heaters because gas heaters lose heat through venting.
good alternative to tankless if the Another thing to consider is that conventional electric systems (that are not fed by an electric pump) will maintain heat and usefulness for an extended period of time, whereas tankless become useless.
Lastly, many electric tankless units cannot keep up with the demands of high-flow fixtures, such as rain shower heads and spa tubs as well as high volume usage.
If you choose a traditional electric unit, consider how many people live in your home the number of bathrooms within. Manufacturers provide information using an average calculation using this information.
