In this article, we’re going to be talking about the best 30-gallon electric water heaters that are available on the market. Some of these are considered short and mid-sized units.
✅Why use an electric water heater?
According to this study carried out by Consumer Reports, electric water heaters are an energy-efficient way of getting hot water.
Electric hot water heaters are generally easier to use when comparing to an equivalent gas unit.
Due to them being shorter in size than other units, the installation and maintenance costs of these units are often lower in comparison to larger units and gas-powered ones.
Additionally, electric water heaters can be used in any home that simply has electricity, whereas not every home has gas, with apartment buildings often only having electricity available for safety reasons.

FAQ
🚰Is a 30-gallon capacity electric water tank enough?
The “draw efficiency” of both gas or electric heaters is generally calculated at approximately 70% of the overall tank storage size.
This is because as a tank is being emptied of hot water, it is also being filled with cold water, so approximately 70% of it is usable hot water.
This means that a 30-gallon unit has a draw efficiency of around 21 gallons.
This is enough to simultaneously maintain one or two bath residence.
💧How long does it take a 30-gallon electric water tank to heat up?
There are a few different factors that come into play when talking about this, including the type of heating element inside the tank and the temperature of the water that is entering the unit.
However, hot water heaters will have two ratings that will help you determine the answer to this question, and these are:
First Hour Rating: The total amount of water in gallons that the heater can supply per hour, starting with a full tank of hot water.
Recovery Rate: The total amount of water in gallons that the heater can supply per hour, starting with an empty tank.
🚰30-gallon electric water heater cost
These units vary in price, ranging from around $500 to $2500.
As we mentioned at the beginning of the article, we have listed the water heaters in order of cost, from the lowest price at the top ($) to the largest price ($$$$$) at the bottom.
