Lower the Temperature on Your Water Heater
Want the easiest way to start saving on natural gas? Adjust your water heater's temperature setting. This simple change requires no special skills yet delivers immediate savings on your utility bills.
Water heater temperature savings
Your water heater is probably working harder than it needs to. Most households don't realize that water heating accounts for approximately 18% of the energy consumed in an average American home. Many manufacturers set water heaters to 140°F by default, which is often higher than necessary for typical household needs.
The savings potential is impressive when you lower your water heater temperature:
- Reducing temperature from 140°F to 120°F can cut your water heating energy consumption by 4-22%
- For each 10-degree reduction in water heater temperature, you'll save up to 5% on water heating costs
- The Department of Energy estimates that lowering your water heater temperature can save between $36 and $61 annually just from reduced standby heat losses
- When you consider additional savings from lower consumption across all home uses (showers, dishwashing, laundry), your total savings could exceed $400 annually
Here's an added bonus: maintaining a lower water heater temperature reduces the workload on your system, potentially extending its operational lifespan. This happens because lower temperatures slow the buildup of mineral deposits and corrosion in your water heater and pipes.
Recommended settings for 2025
The ideal water heater temperature balances energy efficiency, safety, and functionality. While many manufacturers have traditionally set water heaters at 140°F, the U.S. Department of Energy now recommends 120°F as the optimal setting for most households.
This 120°F setting offers several benefits:
- Provides sufficient hot water for daily activities including bathing, laundry, and dishwashing
- Minimizes the risk of scalding (water at 140°F can cause third-degree burns in just five seconds)
- Slows mineral buildup and corrosion, helping maintain efficiency and extending the lifespan of your plumbing and water heater
- Reduces standby heat loss (the heat that escapes from your water heater into the surrounding area)
Certain situations may warrant slightly higher temperature settings:
- If you have a dishwasher without a booster heater, you might need water temperature between 130°F and 140°F for optimal cleaning
- Households with members who have compromised immune systems or chronic respiratory diseases might benefit from higher temperatures (130-140°F) to minimize the risk of Legionella bacteria
Consider installing anti-scald devices or mixing valves at faucets in these cases to maintain safety while ensuring water is hot enough for specialized needs.
How to adjust your water heater
Adjusting your water heater's temperature is straightforward, though the exact process varies depending on whether you have a gas or electric model.
For gas water heaters:
- Locate the temperature dial on the gas control valve near the bottom of the tank
- Use a flathead screwdriver to adjust the dial to 120°F (sometimes marked as "warm" setting)
- Wait several hours, then test the water temperature at a faucet using a thermometer
- Make additional adjustments as needed to achieve your desired temperature
For electric water heaters:
- Turn off the power to the water heater at your electrical panel for safety
- Remove the access panels (typically there are two—one for the upper heating element and one for the lower)
- Gently pull back the insulation to reveal the thermostats
- Use a flathead screwdriver to adjust both thermostats to the same temperature (typically 120°F)
- Replace the insulation and access panels before restoring power
- Wait several hours before testing the water temperature
Since thermostat dials are often inaccurate, always verify the actual water temperature after adjustment. Wait at least two hours without using hot water, then run the hot water tap farthest from your water heater for 2-3 minutes and measure the temperature with a thermometer.
Going away for an extended period? You can save even more by turning your water heater to its lowest setting or completely turning it off. Just make sure you know how to safely restart it when you return.
Seal Air Leaks and Improve Insulation
Air leaks are like tiny money drains throughout your home. When warm air escapes through cracks and gaps, your heating system works overtime to maintain comfortable temperatures, pushing your natural gas bill higher than it needs to be.
Common sources of air leaks
Air leakage happens when outside air enters and heated air leaves your house through various openings. During cold or windy weather, this forces your heating system to consume more natural gas. The biggest culprits hide in predictable spots:
- Attic penetrations: Plumbing pipes, light fixtures, chimneys, soffits, and areas where ceiling joists meet walls
- Wall openings: Electrical outlets, switch plates, window and door frames, baseboards, and where utilities enter the home
- Basement areas: Rim joists (where foundation meets wood framing), plumbing penetrations, and floor joists
- Living spaces: Fireplace dampers, recessed lighting, and around HVAC ducts
Most homeowners check windows and doors first, but the largest air leaks actually hide in the attic and basement. These overlooked areas offer the greatest savings opportunities.
Here's a simple way to spot problems: dirty spots on your insulation signal air movement. If you can see daylight around a door or window frame, you've found air leakage that needs immediate attention.
Insulation upgrades that reduce natural gas usage
Proper insulation works hand-in-hand with air sealing to create an efficient home envelope. Skip either one, and you'll miss substantial savings opportunities.
The Energy Star program shows homeowners can save approximately 15% on heating and cooling costs (roughly 11% on total energy costs) by properly air sealing their homes and adding insulation in attics, floors over crawl spaces, and accessible basement rim joists. For natural gas users, this directly translates to reduced consumption and lower bills.
Energy savings ranging from 10% to 45% can be achieved in existing homes that are properly air sealed and have insulation added to levels prescribed by the 2021 International Energy Conservation Code. This upgrade typically includes:
- Ceiling/attic insulation to recommended R-values
- Floor insulation above unheated spaces
- Wall insulation where feasible
Building envelope insulation serves as your primary defense against energy waste. A well-constructed and insulated envelope delivers numerous benefits, including lower operating costs and reduced environmental impact.
Pay special attention to fireplace flues—one study found that a household heating bill was 30% higher when the home had a missing or broken fireplace damper. Consider installing an inflatable chimney balloon when the fireplace isn't in use.
DIY vs professional sealing options
You can handle many air sealing projects yourself with basic materials and tools. Some situations, though, benefit from professional expertise.
DIY air sealing approaches:
Start by identifying leaks on a windy day. Shut all windows, doors, and fireplace flues, turn off combustion appliances, and turn on all exhaust fans. Use an incense stick to detect air movement around potential leak areas. Try this trick: shine a flashlight at night over suspected gaps while a partner observes from outside—large cracks will appear as rays of light.
Once you've found the leaks, seal different types using:
- Caulk: Perfect for gaps less than ½ inch wide around window and door frames
- Weatherstripping: Best for movable components like doors, windows, and attic access panels
- Foam gaskets: Effective behind outlet and switch plates on exterior walls
- Spray foam: Ideal for larger gaps around windows, baseboards, and pipe penetrations
For attics, focus on areas where pipes, wires, or ductwork penetrate the ceiling. Seal around recessed lights and fill spaces between chimney framing and ceiling joists with proper fire-resistant materials.
When to consider professional help:
Professional expertise makes sense in these situations:
- If you find wet or damp insulation (indicating leaky roof or condensation issues)
- When dealing with a history of ice dams in winter (sign of serious air leaks)
- For homes with little or no attic ventilation
- When you want precise measurement of air leakage through blower door testing
A professional energy assessment with blower door testing can locate air leaks that might otherwise go undetected. This approach identifies leakage points and assesses overall air tightness of your home.
Remember that balancing air sealing with proper ventilation remains crucial—a completely sealed home without adequate ventilation can lead to moisture problems and poor indoor air quality. The goal is reducing uncontrolled air leakage while ensuring your home can still "breathe" through planned ventilation systems.
Use a Programmable or Smart Thermostat
A programmable or smart thermostat gives you powerful control over your natural gas consumption. This small upgrade automatically adjusts temperatures based on your daily routine, delivering consistent savings without any effort on your part.
Smart thermostat savings you can count on
The numbers speak for themselves when it comes to smart thermostat benefits:
- ENERGY STAR certified smart thermostats save approximately 8% on home heating and cooling bills annually, amounting to roughly $50 per year
- You can save up to 10% on heating costs by lowering your thermostat 7-10 degrees for eight hours daily
- Some homeowners see savings between 10-30% on annual energy expenses through smart thermostat usage
What makes these devices so effective? Smart thermostats include features that traditional models simply can't match:
- Remote control capabilities: Adjust your home's temperature from anywhere using your smartphone
- Geofencing technology: Detects when you've left home and automatically adjusts temperatures to save energy
- Learning algorithms: Many models learn your preferences and create energy-efficient schedules automatically
- Energy usage reports: Monthly reports help you track performance and spot additional saving opportunities
Unlike basic thermostats that require constant manual adjustments, smart models maintain consistent temperatures by learning your patterns and optimizing heating cycles. You get better comfort and lower natural gas usage at the same time.
Optimal temperature settings for maximum savings
Getting your thermostat settings right makes all the difference:
- When home and awake: Set your thermostat to 68°F (20°C)
- When sleeping: Program temperatures between 60°F and 67°F for better sleep quality and energy savings
- When away: Lower temperatures by 7-10°F for savings of up to 10% on heating costs
Smart programming around your daily routine maximizes savings without sacrificing comfort. If you leave for work at 8 AM and return at 6 PM, programming a lower temperature during those hours creates substantial annual savings.
Smart thermostats can warm your home shortly before you arrive, so you walk into comfort every time. You might need to adjust these recommendations based on your specific comfort preferences and local climate.
Simple installation and setup steps
Installing a smart thermostat typically takes 30-60 minutes with basic DIY skills. First, make sure your system works with your chosen smart thermostat model.
Installation steps:
- Turn off power to your heating system at the circuit breaker
- Remove your existing thermostat cover and photograph the current wiring
- Label each wire with its terminal connection letter (wire color doesn't matter)
- Disconnect wires and remove the old wall plate
- Mount the new wall plate, keeping it level
- Connect wires to appropriate terminals following manufacturer instructions
- Attach the thermostat to the wall plate and restore power
- Connect to your home's Wi-Fi network following setup instructions
Proper programming is essential for maximizing gas savings:
- Set the correct date and time first so your schedules work properly
- Create different schedules for weekdays and weekends based on your routine
- Use vacation mode when away for extended periods
- Make manual adjustments until the thermostat learns your preferences
- Set temperatures back 7-10 degrees for eight-hour periods to achieve that 10% heating cost savings
Many utility companies offer rebates for ENERGY STAR certified smart thermostats, making this upgrade more affordable. With proper installation and strategic programming, you can reduce natural gas usage significantly throughout winter.
Schedule Regular Furnace and HVAC Maintenance
Here's something most homeowners don't realize: neglecting your furnace is like ignoring your car's oil changes. You might get away with it for a while, but eventually, you'll pay—big time. Regular furnace maintenance often gets overlooked as a money-saving strategy, yet it delivers some of the most impressive results for your natural gas bill.
The numbers are eye-opening. A poorly maintained heating system uses up to 20% more fuel than a well-maintained one. That's like throwing money directly out your window every month!
Your Furnace is Secretly Wasting Money
When your furnace doesn't get proper care, several things happen behind the scenes:
Dirty components restrict airflow, forcing your system to run longer cycles just to heat your home. Dust and debris build up on critical parts, preventing efficient heat transfer. Worn components work harder to achieve the same heating output, burning extra gas in the process.
But here's the kicker: your furnace accounts for approximately two-thirds of your winter energy bills. When it's running inefficiently, that's a massive chunk of wasted money every single month.
There's also a safety factor many people miss. A neglected furnace can develop cracked heat exchangers, potentially allowing carbon monoxide to mix with your home's air. Annual professional inspections catch these dangerous issues before they become health hazards.
Warning Signs Your System Needs Help
Your furnace actually tells you when something's wrong—you just need to know what to listen for:
Strange noises like banging, whistling, or grinding usually mean mechanical problems that need immediate attention. Hot and cold spots throughout your home suggest your system isn't distributing heat properly.
Notice your gas bill creeping up without using more energy? That's often the first sign of declining efficiency. Poor air quality—more dust or humidity changes—can indicate filtration problems.
Systems older than ten years need more frequent check-ups. You might also notice your furnace cycling on and off frequently or struggling to produce adequate heat. Address these issues quickly, and you can restore efficiency and reduce gas consumption.
Finding the Right Technician for Maximum Savings
The technician you choose makes all the difference in both service quality and potential savings.
Start with the basics: proper licensing and insurance as required in your state. Look for certifications like North American Technician Excellence (NATE) or HVAC Quality Installation—these show real expertise.
Don't skip the reference check! Previous customers can tell you whether the technician actually improved their system's efficiency and how thorough the inspection was.
Here's what separates great technicians from mediocre ones: they spend serious time examining your system rather than rushing through basic checks. During a quality evaluation, expect them to test supply air and exhaust gasses, inspect the heat exchanger for damage, clean components, check gas pressure and connections, examine the condensate line, and test all safety controls.
Price matters, but it's not everything. Consider efficiency improvements, warranties, and inspection thoroughness when comparing proposals. The cheapest option often costs more long-term if it misses efficiency issues.
Perfect timing? Schedule maintenance annually before heating season kicks in. This lets technicians fix problems before you need your system most, maximizing your natural gas savings all winter long.
Run Appliances Efficiently
The way you use your home appliances makes a bigger difference than you might think. Small changes to your daily habits can deliver substantial savings without spending a penny on upgrades.
Why full loads save energy
Here's something most people don't realize: your washing machine, dryer, and dishwasher use approximately the same amount of energy regardless of load size. This means running half-empty loads is like throwing money down the drain!
When you wait for full loads, you effectively cut the total number of cycles needed. For dishwashers especially, running only full loads significantly reduces hot water demand, which means less work for your natural gas-powered water heater.
Just remember to find the sweet spot—overloading can actually decrease efficiency and cleaning performance. Check your manufacturer's recommendations to get the optimal load size for maximum energy efficiency.
Cold water washing and drying tips
Want to hear some eye-opening numbers about laundry? Between 75% and 90% of all energy your washer uses goes toward heating water. That means you can reduce energy usage by up to 90% simply by switching to cold water!
Each household making this simple switch could eliminate approximately 1,600 pounds of carbon dioxide emissions annually. Plus, cold water washing brings bonus benefits:
- Keeps clothing colors bright and prevents fading
- Reduces fabric shrinkage
- Minimizes wrinkles, saving you ironing time and energy
For drying, air-drying cuts a load's carbon usage by approximately 75%. Can't always hang clothes outside? Use your washer's high-speed spin setting first to remove excess moisture—less water means shorter drying times.
Energy-efficient appliance usage
Smart appliance habits extend far beyond the laundry room. These simple practices can reduce natural gas consumption throughout your home:
For your dryer: Use moisture sensors when available—they automatically stop the cycle once clothes reach perfect dryness, preventing wasteful over-drying. Clean that lint screen after every load to keep air flowing freely.
For cooking: Cover pots and pans to retain heat, match pan sizes to burner dimensions, and look for blue flames in gas appliances. Yellow flames indicate inefficient burning that wastes fuel.
For refrigeration: Set your refrigerator between 35°-38°F and freezer at 0°F. Test door seals with the dollar bill trick—if you can easily pull it out, you need a new seal.
For dishwashers: Skip the heat-dry option, which significantly increases energy usage. Scrape dishes instead of pre-rinsing them to conserve both water and the natural gas used to heat it.
These practical adjustments work together to meaningfully reduce your natural gas consumption without sacrificing convenience or comfort.
Switch to High-Efficiency Appliances
Upgrading to high-efficiency appliances offers a powerful way to permanently reduce your natural gas bill. While the previous strategies focus on daily habits and maintenance, energy-efficient appliances deliver consistent savings throughout their entire lifespan.
What qualifies as high-efficiency
High-efficiency appliances meet strict energy performance standards established by independent certification programs. The most trusted standard comes from ENERGY STAR, a program run by the U.S. Environmental Protection Agency and Department of Energy.
To earn ENERGY STAR certification, products must:
- Undergo testing by independent third parties
- Meet strict efficiency specifications that exceed minimum federal standards
- Perform equally or better than standard products
- Deliver measurable energy savings
For example, ENERGY STAR-qualified refrigerators use approximately 15% less energy than the minimum federal standard. Similarly, ENERGY STAR-certified freezers consume 10% less energy than non-qualified models.
ENERGY STAR appliances to consider
Focus on replacing natural gas-consuming appliances for maximum bill reduction:
- Furnaces: High-efficiency condensing models are installed in 75% of new construction homes versus just 8% for comparable electric heat pumps
- Water heaters: Options include high-efficiency gas storage, tankless systems, heat pump, and solar water heaters
- Cooking equipment: ENERGY STAR certified cooking products are approximately 18% more efficient than non-certified options
Here's what makes natural gas appliances particularly attractive: households using natural gas for heating, cooking, and clothes drying save an average of $1,132 annually compared to all-electric homes. Natural gas is currently about 3.5 times cheaper than electricity and projected to remain significantly more affordable through at least 2050.
The overall efficiency of natural gas delivery systems reaches 92% from source to home, versus just 38% for electricity. This higher efficiency means using less energy for the same performance.
Rebates and incentives in 2025
Financial assistance makes upgrading to high-efficiency appliances more affordable:
Check manufacturer and utility company rebates on ENERGY STAR certified products. Many local utilities offer substantial rebates to encourage energy efficiency upgrades.
Government programs like the Inflation Reduction Act's Home Energy Rebates are expected to begin in late summer or early fall 2025. These include:
- Home Appliance Rebate Program (HARP) - Provides point-of-sale rebates for income-eligible consumers on efficient electric equipment
- Whole Home Efficiency Rebates (HOMES) - Offers rebates based on energy savings achieved
Households earning up to 150% of Area Median Income will qualify for these programs. Remember that rebates aren't retroactive - you must apply and receive approval before purchasing appliances or completing upgrades.
Change Air Filters Frequently
Here's a simple task that takes five minutes but can cut your gas bills significantly. Changing your air filter might seem minor, yet it plays a crucial role in keeping your furnace running efficiently throughout the heating season.
How dirty filters waste your money
When your furnace filter gets clogged, your heating system works overtime—and that shows up on your gas bill. A dirty filter restricts airflow, forcing your furnace to run longer cycles just to maintain the temperature you want. This restriction can force your system to consume up to 10% more fuel than necessary.
Think of it this way: a clogged filter creates a chain reaction. Less air flows through the system, the air-to-fuel ratio gets thrown off, and your furnace burns extra gas to compensate. This inefficiency doesn't just cost you money—it can also lead to:
- Premature wear on system components
- Incomplete combustion that creates more pollutants
- System overheating from poor air circulation
When to change your filter
Most furnace filters need replacement every 1-3 months, depending on your specific situation. Here's what works best:
- Standard fiberglass filters: Replace every 1-2 months
- Pleated filters: Change every 3-4 months
- HEPA filters: Replace annually
Check your filter monthly during heavy heating periods. Some homes need more frequent changes:
- Pet owners should change filters more often
- Dusty environments require more regular replacement
- Systems that run continuously need frequent filter changes
Quick filter replacement steps
Changing your furnace filter is straightforward:
1️⃣ Turn off your furnace at the thermostat or electrical panel 2️⃣ Find the filter compartment (usually at the air return duct or blower entrance) 3️⃣ Remove the cover to access the filter 4️⃣ Slide out the old filter carefully with both hands 5️⃣ Check the size printed on the frame for replacement 6️⃣ Insert the new filter with the arrow pointing toward the blower motor 7️⃣ Replace covers and restore power
A clean filter doesn't just reduce your natural gas consumption—it also extends your heating system's life, potentially saving you hundreds in repair costs. Small effort, big savings!
