Tankless electric water heaters are the newest craze in home heating. The idea is only to have one hot water tank that you can use and automatically switch to electricity when needed. This article will cover the basics of how much electricity a tankless electric heating system uses.
What is a tankless electric water heater?
A tankless electric water heater uses electricity to heat only the water. This means that you don’t have to wait for a water heater to heat up before using it, and you won’t have to worry about filling up your tank with water every time you shower.
Tankless electric water heaters can be installed in any room in your home and are often cheaper than traditional electric water heaters.
What are the key features of a tankless water heater?
Tankless water heaters are becoming more popular yearly because they use less energy than traditional water heaters. There are a few key features to look for when selecting a tankless water heater:
- Capacity: The size of the tankless water heater is important, as the larger the tank, the more water it can hold. Look for a model with at least 5 gallons of capacity.
- Efficiency: The efficiency of a tankless water heater refers to how much energy it uses per gallon of hot water produced. Look for models that have an efficiency rating of at least 90%.
- Design: The design of a tankless water heater is also important. Make sure to choose one with features like automatic shutoff and drain-back prevention to prevent clogs and overflows.
How much electricity does a single gallon of water use?
A gallon of water uses about 3,500-kilowatt hours (kWh) in an electric water heater. This is based on a typical U.S. household using around 8,000 kWh per month. If the water heater is used only for hot water, it will use less energy since hot water takes up less energy than cold water.
How many gallons of water can a single tankless electric water heater heat up?
Electric water heaters use a lot less energy than traditional water heaters. A tankless electric water heater typically uses between 0.25 and 2 watts of power, much lower than the average 110-volt electrical outlet’s 3.6-watt usage.
A tankless electric water heater can save you up to 75% on energy costs compared to a standard electric water heater.
Pros and cons of a tankless electric water heater
Tankless electric water heaters use less electricity than traditional electric water heaters. They can also be more efficient, using less hot water while providing the same level of convenience.
However, they can be more expensive to purchase and maintain than traditional water heaters and may require special installation or modifications to your home.
Anyone who has ever had to deal with a broken water heater knows how costly and inconvenient it can be. Luckily, there are solutions available that don’t require you to call in a professional plumber.
One such solution is a tankless electric water heater, which uses electricity rather than water to heat your home’s hot water.
Depending on your chosen model, a tankless electric water heater might use as little as 10 kWh or as much as 50 kWh per day. So if you’re looking to save money on your energy bill this winter, consider adding a tankless electric water heater to your list of options.
