Your faucets, showerheads and plumbing appliances consume plenty of hot water. In fact, the Department of Energy states that water heating is the second-largest utility cost behind space heating and cooling, accounting for about 18% of your monthly bill. Learn how much energy the average water heater uses and helpful tips to reduce your water heating costs.
The exact cost to run an electric water heater depends on the size of the unit, how much you use it, its power draw and what you pay for electricity. As an example, a medium-sized, 40-gallon water heater that draws 4500 watts and is active for two hours a day at a rate of $0.13 per kilowatt-hour (kWh) costs about $1.17 to run per day, which comes to $35 per month or $426 per year.
If your water heater runs on natural gas, you must consider the size of the unit, how much you use it, its power draw and what you pay for natural gas. As an example, a medium-sized, 40-gallon water heater that uses .205 therms per hour and is active for two hours a day for a price of $1 per therm costs about $0.62 to operate per day, which comes to $18.60 monthly or $226 per year.
As you can determine from the examples above, gas water heaters typically cost less to run than equivalent electric models because natural gas prices tend to run lower than electric prices. Refine the calculations with your exact energy usage and rates to create a more accurate picture of gas vs. electric water heater costs.
Whether your water heater runs on electricity or gas, you can cut your utility costs with these money-saving tips.
Keep in mind that every time you turn on a hot water tap, you have to pay to heat it. Modify your day-to-day habits to lower your bills. Here’s how:
Leaky faucets, showerheads and pipes can waste significant amounts of hot water. For instance, one drip per second can waste as much as 1,600 gallons per year. Eliminate this waste by repairing plumbing leaks as soon as you notice them.
Modern regulations require new showerheads to consume 2.5 gallons per minute (gpm) or less while kitchen faucets are limited to 2.2 gpm. New bathroom faucets must have flow rates below 1.5 gpm.
You can purchase quality, low-flow kitchen and bathroom fixtures for about $10 to $20 each, resulting in approximately 60% savings on water use. Look for the ENERGY STAR® WaterSense label to maximize efficiency without negatively impacting performance.
The default setting is 140 degrees. Lower this to 120 degrees to save on water heating costs and minimize the risk of scalding at the tap. Just don’t go any lower than 120 degrees to prevent microbial growth in the tank.
If the water heater doesn’t have a temperature readout, determine the setting with a thermometer at the bathroom or kitchen faucet. Adjust the water heater’s dial, wait two hours and check the water’s temperature. Repeat this process until the thermometer reads 120 degrees.
Both electric and natural gas water heaters can be insulated with special jackets available at home improvement stores. Be careful to install the jacket correctly to avoid creating a dangerous operating situation. If you’re not sure how to proceed, ask a professional for help. Once the tank is insulated, add insulation to the hot and cold pipes coming from the water heater to help things heat up faster at the tap.
If the water heater is nearing the end of its life span, consider replacing it with an ENERGY STAR-rated model. A tankless water heater is a good option. This upgrade can save approximately 34% on your water heating bills by generating hot water on demand and eliminating standby heat loss. Save even more by replacing your hot water appliances with high-efficiency models, including your dishwasher and washing machine.
