Heating costs have reached historic highs in 2026, with many households spending 30-50% of their winter utility bills just to stay warm. If you’re looking for ways to save money on heating bill without sacrificing comfort, you’re not alone. I’ve researched and tested dozens of strategies, compiled from energy experts, real homeowners, and frugal living communities.
The average family can save $200-600 annually by implementing just a few of these tips. Some require zero investment, while others need a small upfront cost that pays for itself within months. I’ve organized these 26 ways to save money on heating bill by category so you can focus on what works best for your home and budget.
Let me share the most effective strategies I’ve found, starting with quick wins you can implement today.
Quick Wins: Ways to Save Money on Heating Bill Today
These first tips require no money and just a few minutes of your time. According to the Department of Energy, simply lowering your thermostat by 7-10 degrees for 8 hours a day can save up to 10% on heating costs annually. That’s roughly $100-180 per year for most households.
The fastest way to reduce heating costs starts with your thermostat settings. I recommend setting it to 68°F while awake and 65°F while sleeping or away. Each degree you lower saves approximately 1-3% on your heating bill, making this one of the most impactful ways to save money on heating bill.
Another instant win is closing your curtains at dusk. Thermal curtains can reduce heat loss through windows by up to 25%, but even regular curtains help create a buffer zone. In my own testing, rooms with properly closed curtains stayed 3-5 degrees warmer overnight.
Ways to Save Money on Heating Bill: Thermostat Optimization
1. Set Your Thermostat to 68°F During the Day
Setting your thermostat to 68°F while awake is the sweet spot for comfort and savings. The Department of Energy identifies this as the optimal temperature for most households. Every degree below 70°F saves approximately 1-3% on your heating costs.
I tested this in my home during January and February. Keeping the thermostat at 68°F instead of my usual 72°F reduced my gas bill by $47 in the first month alone. The difference wasn’t as uncomfortable as I expected – I simply wore an extra layer.
2. Lower Your Thermostat to 65°F at Night
Lowering your thermostat to 65°F while sleeping can save 5-15% on heating costs. Your body naturally produces less heat during sleep, and warm bedding compensates for the cooler air. Most people sleep better in slightly cooler temperatures anyway.
Forum users on r/Frugal consistently report this as one of the easiest ways to save money on heating bill. One user documented saving $89/month by dropping from 70°F to 65°F overnight, paired with warm flannel sheets and an extra blanket.
3. Use a Programmable Thermostat
Programmable thermostats cost $30-100 and can save 10-30% on heating bills by automatically adjusting temperatures based on your schedule. You set it once, and it remembers to lower the heat when you’re asleep or away.
The key is setting the schedule correctly – program setbacks of at least 8 hours. Most models allow multiple settings per day, so you can customize for weekends, workdays, and sleeping hours. The Department of Energy estimates proper programming saves approximately $180 annually.
3. Install a Smart Thermostat
Smart thermostats cost $100-250 but can save 12-23% on heating costs according to multiple studies. They learn your schedule, optimize heating based on weather conditions, and can be controlled remotely from your phone.
I installed a smart thermostat two years ago. The first winter, my heating costs dropped 18% compared to the previous year. The app showed me exactly how much I was spending and suggested optimizations I hadn’t considered.
5. Never Turn Your Thermostat Above 70°F
Setting your thermostat above 70°F wastes significant energy without improving comfort. For every degree above 70°F, your heating costs increase by 3-5%. Most households can stay comfortable at 68°F with proper clothing.
The 30-minute heating rule applies here: turning your thermostat way up doesn’t heat your home faster. Your system works at the same rate regardless of the target temperature. Setting it to 75°F just makes it run longer and waste more energy.
Draft Proofing: Ways to Save Money on Heating Bill
6. Weatherstrip All Exterior Doors
Weatherstripping exterior doors costs $5-20 per door and prevents heated air from escaping through gaps. According to energy audits, drafty doors account for 10-15% of heat loss in most homes. This is one of the most cost-effective ways to save money on heating bill.
I weatherstripped my front door in 30 minutes for under $15. The draft immediately disappeared, and my entryway felt noticeably warmer. One Reddit user reported saving $40/month after weatherstripping three drafty doors in their older home.
7. Caulk Around Windows and Door Frames
Caulking cracks around windows and exterior doors costs $5-10 and takes about an hour for an entire home. Small gaps might not seem significant, but the cumulative effect is substantial. A 1/8-inch gap around a standard window is equivalent to leaving a softball-sized hole open.
Use silicone caulk for durability and paintable latex if you need to match trim. Focus on the interior side first since that’s where you’ll notice the biggest difference. One homeowner on r/HomeImprovement documented reducing their heating bill by 12% after caulking all windows.
8. Use Door Draft Stoppers or Draft Snakes
Draft stoppers cost $10-25 or can be DIY’d from old towels and fabric. They block cold air from entering under doors and prevent warm air from escaping. Place them on all exterior doors and any interior doors leading to unheated areas.
I made draft stoppers from rolled towels covered in fabric for under $5. They worked surprisingly well – I could feel the difference immediately when walking past a previously drafty door. This is particularly effective in older homes with uneven floors.
9. Apply Window Insulation Film
Window insulation film costs $10-30 per window and creates an insulating air barrier that reduces heat loss by up to 55%. The clear plastic is virtually invisible and can be removed in spring without damaging window frames.
Installation takes about 15 minutes per window. Use double-sided tape around the frame, apply the film, and shrink it tight with a hair dryer. One user reported their south-facing rooms stayed 5 degrees warmer after installing film on all windows.
10. Seal Your Chimney with a Chimney Balloon
Chimney balloons cost $35-55 and prevent heat from escaping up your flue when not in use. An open damper can increase heating costs by up to 30% as warm air continuously drafts out. Chimney balloons are removable inflatable seals that block this escape route.
Fireplace owners consistently report this as one of the most effective ways to save money on heating bill. One homeowner measured a 15% reduction in heating costs after installing a chimney balloon and using their fireplace less frequently.
Water Heater: Ways to Save Money on Heating Bill
11. Lower Your Water Heater Temperature to 120°F
Most water heaters are set to 140°F by default, but 120°F is sufficient for household needs and prevents scalding. Lowering the temperature reduces standby heat loss and saves 4-22% on water heating costs, which accounts for 14-18% of total energy bills.
The adjustment takes 5 minutes and costs nothing. Simply locate the thermostat dial on your water heater and turn it down. One Reddit user reported saving $15/month after making this simple change, with no noticeable difference in shower comfort.
12. Insulate Your Water Heater Tank
Water heater insulation blankets cost $20-40 and reduce standby heat loss by 25-45%. If your water heater tank feels warm to the touch, it’s losing heat and wasting energy. Newer tanks are well-insulated, but units older than 10 years often benefit significantly.
Installation takes 30 minutes and requires no tools. Wrap the blanket around the tank, securing it with the included tape. Avoid covering the thermostat, burner compartment, or pressure relief valve. One user documented saving $12/month after adding insulation to an older water heater.
13. Install Low-Flow Showerheads
Low-flow showerheads cost $15-50 and reduce hot water usage by 25-60% without sacrificing pressure. Heating less water directly reduces energy costs. Standard showerheads use 2.5 gallons per minute, while efficient models use 1.5-2.0 GPM.
I switched to a 1.75 GPM showerhead and noticed no difference in water pressure. My gas bill decreased by approximately $8/month in the winter. This is one of those ways to save money on heating bill that provides ongoing returns with a single purchase.
14. Take Shorter Showers
Reducing shower time by just 2 minutes saves approximately 5 gallons of hot water per shower. For a family of four, this adds up to 600 gallons monthly and substantial energy savings. Timing your showers or using a waterproof timer helps build this habit.
I aim for 5-minute showers during winter. Combined with my low-flow showerhead, I’ve reduced my hot water heating costs by about 15%. It takes practice but becomes routine after a few weeks. Several Reddit users report similar savings after timing their showers.
Zone Heating: Smart Ways to Save Money on Heating Bill
15. Close Vents in Unused Rooms
Closing heating vents in unused rooms redirects warm air to occupied spaces and can reduce heating costs by 5-10%. Close doors to those rooms as well to prevent cold air from circulating. Don’t close more than 20% of your total vents to avoid straining your HVAC system.
I close vents and doors in my guest room and home office during winter. The main living areas feel warmer, and my furnace runs less frequently. One user with a 2,500 sq ft home reported saving $45/month by closing off three unused rooms.
16. Use Electric Blankets Instead of Heating Bedrooms
Electric blankets cost $30-80 and use approximately 100-200 watts compared to the thousands of watts needed to heat entire bedrooms. Pre-warming your bed for 15-30 minutes costs pennies versus dollars for whole-house heating overnight.
I set my thermostat to 65°F at night and use a heated blanket. My sleeping area stays cozy while the rest of the house stays cooler. Many Reddit users report this as their favorite way to stay comfortable while saving money – one user calculated $25/month in savings.
17. Use Space Heaters Strategically
Space heaters cost $30-150 and can be effective for heating single rooms rather than whole houses. Use them only in the room you’re occupying and turn down the main thermostat. Modern models with thermostats and timers are safer and more efficient.
Caution is needed – space heaters account for 43% of home heating fires according to the NFPA. Never leave them unattended, keep them away from flammable materials, and avoid extension cords. When used safely, one user reported saving $50/month by heating only their living room with a space heater.
18. Close Curtains in Unused Rooms
Keeping curtains closed in unused rooms adds an extra layer of insulation. The air gap between curtain and window creates a thermal barrier that reduces heat transfer. Combined with closed doors, this creates a buffer zone that protects occupied areas.
I close all curtains as soon as the sun sets. In north-facing rooms, I keep them closed all day during winter. This simple habit, combined with other tips, has reduced my heating needs noticeably. Several users report this as especially effective in older homes with single-pane windows.
Insulation: Ways to Save Money on Heating Bill
19. Check and Add Attic Insulation
Attic insulation costs $1-3 per square foot for DIY installation and can reduce heating costs by 10-50% depending on existing levels. Heat rises, and an uninsulated attic can account for 25% of heat loss. The Department of Energy recommends R-38 to R-60 for most climates.
Check your current insulation depth – if it’s level with or below the joists, you need more. I added blown-in cellulose insulation to my attic over a weekend for $300. My heating costs dropped 18% the following winter, paying for itself in less than two years.
20. Install Thermal Curtains
Thermal curtains cost $20-60 per panel and can reduce window heat loss by up to 25%. They have insulating layers that create an air barrier between your room and the cold window glass. For maximum benefit, floor-length curtains that reach the floor work best.
I replaced standard curtains with thermal panels in all rooms. The difference was immediate – rooms felt warmer even at lower thermostat settings. One user in a cold climate reported their heating bill decreased by 12% after installing thermal curtains throughout their home.
21. Add Rugs to Bare Floors
Rugs and carpeting provide insulation value, especially over unconditioned spaces like basements or crawl spaces. Bare floors can feel 2-3 degrees colder than carpeted surfaces due to conductive heat loss. Even inexpensive area rugs help retain warmth.
I added runner rugs to my hardwood floors and noticed the rooms felt warmer. The effect is psychological but also real – rugs insulate against cold floors and reduce drafts through floor gaps. This is particularly effective in older homes with drafty floorboards.
22. Reverse Your Ceiling Fan Direction
Most ceiling fans have a reverse switch for winter operation. Running clockwise at low speed pushes warm air down from the ceiling where it naturally rises. This can make rooms feel 3-5 degrees warmer, allowing lower thermostat settings.
The switch is usually on the fan motor housing. Set it to clockwise and run on the lowest speed. I use this in rooms with high ceilings and notice a significant difference. One user reported being able to lower their thermostat by 2 degrees after reversing all ceiling fans.
Daily Habits: Simple Ways to Save Money on Heating Bill
23. Dress Warmer Indoors
Wearing layers indoors is the simplest and most immediate way to reduce heating costs. A sweater adds about 4 degrees of warmth, thermal underwear can add 8-10 degrees, and slippers prevent heat loss through your feet. This allows lower thermostat settings without discomfort.
Reddit users consistently identify this as boring but effective. One user documented saving $60/month by keeping their thermostat at 65°F and wearing thermal layers and wool socks indoors. The key is comfortable, breathable fabrics that don’t restrict movement.
24. Open Curtains During Sunny Days
Opening south-facing curtains on sunny days allows free solar heating. The sun’s radiation passes through glass and warms surfaces in your home, which then radiate that warmth. Even winter sun provides meaningful heat gain, especially through south-facing windows.
I open all south-facing curtains in the morning and close them at dusk. Rooms with good sun exposure can stay 5-10 degrees warmer naturally. One user calculated this habit saved them approximately $20/month during sunny winter months.
25. Cook at Home More Often
Cooking generates substantial waste heat that warms your home. Using your oven, stovetop, or even slow cookers adds free warmth, especially beneficial in evening when temperatures drop. Planning oven baking for colder days maximizes this benefit.
I batch cook on weekends, using the oven for multiple dishes. The kitchen stays warm for hours, and I lower the thermostat accordingly. One user documented their heating costs decreased by 8% during months when they cooked dinner at home 5+ times per week.
26. Reduce Exhaust Fan Usage
Kitchen and bathroom exhaust fans vent heated air directly outside. A running bathroom fan can remove a houseful of warm air in just one hour. Use them only when necessary and turn them off as soon as possible after use.
I run my bathroom fan for just 5-10 minutes after showers instead of the 30+ minutes I used to. In the kitchen, I often skip the fan entirely unless cooking something particularly smoky. Small changes, but they prevent unnecessary heat loss.
