How to Save Money on Heating in a Rented Apartment (12 Deposit-Safe Tricks)

Your heating bill climbs every winter, and as a renter you can't replace the furnace, the radiators or the single-pane windows that determine most of it. Here's the good news: learning how to save money on heating in a rented apartment doesn't require touching anything your landlord owns. The drafts, the windows, the thermostat and the daily habits are yours to manage — and together they can take a real bite out of the winter bill without risking a cent of your deposit.

Why Renters Overpay for Heat in the First Place

Heating and cooling account for nearly half of a typical home's energy use, and older rental buildings are where that number hurts most. Drafty window sashes, unsealed doors, radiators blocked by furniture and thermostats set once in November and never touched again — all of it forces your heating system to work harder than it should.

There's a second, quieter reason renters overpay: nobody reads the bill. A higher total doesn't always mean you used more energy. Before you change a single habit, compare the kilowatt-hours or therms on this winter's bill with last winter's, and check the number of billing days. If usage is flat but the bill jumped, your rate changed — and that's a different problem from a drafty window. Knowing which one you're fighting saves you from fixing the wrong thing.

How to Save Money on Heating in a Rented Apartment: the No-Permission Fixes

Start with everything that needs no landlord approval at all. None of these require tools, drilling or permanent changes, and all of them come with you — or peel off cleanly — when you move out.

1. Set the Thermostat Back — the Single Biggest Free Win

The US Department of Energy's guidance is simple and well tested: turning your thermostat back 7 to 10 degrees for 8 hours a day can cut your heating bill by up to 10 percent a year. Set it to around 68 degrees while you're home and awake, then drop it while you sleep and while you're at work.

Do the math on a $190 monthly winter heating bill: a 10 percent saving is $19 a month, or roughly $95 across a five-month heating season — for pressing two buttons. The old myth that reheating "uses more energy than you saved" doesn't survive the data; heat loss slows while the apartment is cooler, so the furnace genuinely runs less overall. Two exceptions: heat pumps should only be set back a couple of degrees (deep setbacks can trigger expensive backup strip heating), and a properly sized boiler system may recover slowly from a deep setback, so start modest and watch how yours behaves.

2. Window Insulation Film for Renters

If your apartment has old windows, this is the highest-impact $20 you'll spend all winter. A window insulation film kit — clear plastic sheeting, double-sided tape and a hair dryer — creates an invisible second pane that traps warm air inside. It goes up in about 15 minutes per window and peels off cleanly in spring.

Start with the leakiest windows only: hold a lit candle or a strip of tissue near the sash on a windy day and watch where it flickers. In many older apartments, sealing just two or three bad windows makes the whole room feel warmer, because the cold draft that used to roll across the floor is gone. Don't film windows you need as a fire escape route, and never block a window that must open for ventilation.

3. Draft Stoppers for Doors and Gaps

Cold air sneaks in under exterior doors, hallway doors and doors to unheated spaces — and a weighted draft stopper (sometimes called a draft snake) stops it in seconds. Slide-under models need no hardware at all; adhesive door sweeps work on high-traffic doors and peel off at move-out. Check the front door first: a half-inch gap under it is like leaving a small window open all winter.

While you're at it, run your hand along window sashes for rattles. Removable weatherstripping tape on a rattly sash is cheap, invisible and deposit-safe, unlike caulk, which you should not apply without written permission.

4. Thermal Curtains: Open by Day, Closed at Night

Heavy thermal or blackout curtains are a second layer of insulation you can hang on a tension rod — no drilling, no holes, no landlord conversation. The routine matters as much as the curtains: open them on sunny days to let free solar heat in, and close them the moment the sun sets to trap that warmth overnight. On north-facing windows that never see sun, just keep them closed all winter.

Layering helps too. A sheer curtain behind a thermal panel looks better and insulates slightly better than either alone, and it costs nothing if you already own both.

5. Rugs, Reversed Fans and Clear Vents

Three free moves that people forget every year. First, rugs on bare floors: cold floors pull heat from your feet and make the whole room feel colder than the thermostat says, so cover the floor you actually walk on. Second, reverse your ceiling fan to run clockwise on low in winter — it pushes warm air that pools at the ceiling back down to where you sit. Third, move furniture off radiators and vents. A couch parked against a radiator is heating the back of your couch; pull it six inches out and the room gets that warmth instead.

6. Close Off Rooms You Don't Use — Carefully

Shutting the door to a spare room and partially closing its vent can trim the space you're paying to heat. But keep two safety rules. Never close a room completely in a freezing climate without checking its pipes — a room that drops below freezing can split a pipe, and that repair dwarfs any heating saving. And never shut off a radiator entirely in winter; turn it low, not off, and keep the room above about 50 degrees.

7. The Space Heater Cost-Per-Hour Trap

A space heater feels cheap because it's small. It isn't. A standard 1,500-watt space heater costs roughly 25 cents an hour to run at average US electricity prices — that's $6 a day, or $180 a month, if it runs around the clock. It only saves money when it lets you turn the main thermostat down: heat the one room you're sitting in, drop the rest of the apartment to 62 or 63 degrees, and the math works. Run it alongside full central heating and you've simply bought yourself a second heating bill.

Safety matters as much as savings here. Keep space heaters three feet from anything flammable, never leave one running while you sleep or while you're out, and never plug one into a power strip — plug it directly into a wall outlet.

8. What to Ask Your Landlord — in Writing

The fixes above are yours. The next tier belongs to your landlord, and the trick is asking the right way. A vague complaint ("it's cold") gets ignored. A specific written request gets answered. Try this: "The front door has a half-inch gap letting in cold air; could maintenance add weatherstripping before December?" Ask about furnace filters (a clogged filter makes the system work harder and is usually the landlord's job), about gaps around pipes and windows, and about whether the thermostat can be upgraded — a programmable thermostat pays for itself fast, and many landlords will approve it if you offer to leave it installed when you move out.

Put every request in writing — email or a tenant portal message, not a hallway conversation. If a repair drags on, you have a dated record, and that record is worth more than any argument. If bills are your weak spot generally, our guide to negotiating your bills down uses the same script-and-paper-trail approach for phone, internet and insurance.

9. Energy Assistance Programs for Renters

If the bill is already hard to pay, don't wait for a shutoff notice — help is much easier to get while the balance is small. The federal LIHEAP program (Low Income Home Energy Assistance Program) helps eligible households with heating and cooling costs, and many states and utilities run their own assistance funds on top of it. Dial 2-1-1 to find programs in your area, and call your utility directly to ask about budget billing (which spreads winter costs evenly across the year) and hardship payment plans.

Many renters assume assistance is only for homeowners. It isn't — renters who pay for heat directly, and even some who pay heat through rent, can qualify depending on the state. A ten-minute call to 2-1-1 is worth more than a winter of $200 bills you can't afford. The Consumer Financial Protection Bureau also publishes guidance on handling bills you can't pay and dealing with debt collectors if a utility balance has already gone to collections.

10. Read Your Meter and Catch Billing Errors

Estimated bills are a quiet money leak. If your utility estimates usage for a month or two and then "trues up," you can get a shocking catch-up bill in February. Submit an actual meter reading through your utility's app or website when you can — most utilities accept customer readings — and compare the therms or kilowatt-hours on each bill against the same month last year. A sudden usage jump with no lifestyle change usually means a leak, a stuck heater or a billing error, and all three are worth a phone call.

11. Lower the Water Heating Bill While You're at It

Water heating is the second-biggest energy cost in most homes, and renters control it more than space heating. Set the water heater to 120 degrees if you can access it (many landlords will do this on request), wash clothes in cold water, and take shorter showers — a five-minute shower instead of a bath saves both water and the energy used to heat it. These are small numbers individually, but they land on the same utility bill as your heating, so they add up in the same place.

12. The $30 Weekend Plan: What It Actually Saves

Here's the whole plan in one weekend, for about $30 out of pocket:

• Window film kit for the two worst windows: ~$18
• Door draft stopper for the front door: ~$10
• Thermostat setback routine (free): up to 10% off heating
• Thermal curtains on a tension rod (if you don't own them): ~$25
• Furniture moved off radiators, vents cleared, fan reversed: free

On a $190 monthly winter heating bill, the thermostat setback alone is worth roughly $19 a month. Add the draft sealing and the warmer-feeling rooms — which make a 68-degree apartment feel like a 70-degree one, so you stop nudging the thermostat up — and a realistic winter saving is $25 to $40 a month, or $125 to $200 across a five-month heating season. Not life-changing money. But it's money you were previously paying to heat the outdoors, and the fixes cost less than one month of the saving.

If winter bills are squeezing a budget that's already tight, pair this with our silent money leaks checklist and a free budget planner session: the heating bill is one leak, but most tight budgets have four or five, and plugging them together is how a month stops feeling like an emergency. For the bigger picture, our guide to stopping the paycheck-to-paycheck cycle shows how to turn freed-up money into a buffer instead of letting it evaporate.
