# Electric Water Heater (Tankless) Energy Calculator (Cost and kWh Usage)

Electric water heaters have become increasingly popular in recent years, and for good reason. They are more energy-efficient than traditional water heaters and can save you money in the long run. However, it is important to understand the energy consumption and costs associated with using an electric water heater (tankless).

## How To Use This Calculator

Using this energy calculator is a simple and will help you determine the costs of running your appliance. Click on ‘Calculate’ to use the predefined values, or enter your daily usage in hours, appliance watts, and your current energy costs in dollars. The calculator will provide you with the daily, monthly, and yearly results. It’s important to ensure the accuracy of the information entered to get the most accurate results.

### Hours Used Per Day

Enter the number of hours you estimate the appliance will be on throughout the day. To use fractions of an hour please use a decimal point in the form.

For example: 1 hour and 30 mintes would be 1.5, and 3 hours and 15 minutes would be 3.25

### Power Used in Watts

The calculator already includes a default average wattage. If your appliance uses a different wattage then enter it in the calculator.

### Your Energy Rate in kWh

The calculator includes an average energy rate (price in \$/kWh) to use for the calculation. This may not be the exact price that you’re currently paying for electricity. If you know your energy rate please enter your price per kilowatt-hour.

## Energy Consumption

An electric water heater (tankless) uses 6600 watts of energy to heat water as it passes through the unit. This means that the heater is constantly using energy, even when there is no demand for hot water. While this may seem like a waste of energy, it actually saves money in the long run by reducing standby energy losses.

To put this energy consumption into perspective, let’s compare it to other household appliances:

• Microwave: 1000 watts
• Hair Dryer: 1600 watts
• Space Heater: 1500 watts
• Electric Water Heater (Tankless): 6600 watts

As you can see, an electric water heater (tankless) uses significantly more energy than other household appliances. However, it is important to note that the water heater is not always in use and only heats water on demand.

## Importance and Relevance

The importance of understanding the energy consumption and costs associated with using an electric water heater (tankless) cannot be overstated. With rising energy costs and a growing concern for the environment, it is important for individuals to make informed decisions about their energy usage.

Furthermore, the impact of electric water heaters (tankless) extends beyond the individual. By reducing energy consumption, we can collectively reduce our carbon footprint and contribute to a more sustainable future.

## Cost in Dollars of Energy Usage

To calculate the cost of using an electric water heater (tankless), simply multiply the energy consumption (in watts) by the cost of energy (in dollars per kilowatt-hour).

## Money Saving Tips

There are a number of ways to save money when using an electric water heater (tankless):

• Lower the temperature: Lowering the temperature of your water heater by just a few degrees can save you money on your energy bills.
• Use less hot water: Take shorter showers and wash your clothes in cold water to reduce the amount of hot water you use.
• Install a timer: Install a timer on your water heater to only heat water during peak usage times.
• Insulate your pipes: Insulating your hot water pipes can reduce standby heat loss and save you money on your energy bills.

By implementing these money-saving tips, you can reduce your energy consumption and save money on your electricity bills in the long run.

In conclusion, electric water heaters (tankless) are a more energy-efficient alternative to traditional water heaters. While they may use more energy than other household appliances, this energy consumption can be reduced through informed decisions and energy-saving practices. By understanding the energy consumption and costs associated with using an electric water heater (tankless), individuals can make informed decisions about their energy usage and contribute to a more sustainable future.
