As the temperature starts to take a dip, there are some simple things you can do to cut back on heating bills. Beyond replacing old windows and increasing insulation, here are 20 unexpected ways you can keep your house warm this winter.

1. Check the Radiators

If you have furniture blocking the radiators, you’re blocking heat from getting into the room. Move the couch away from the radiator and the room should warm up faster.

2. Use Rugs

Rugs not only work to style a room, but they also do a good job of keeping your feet toasty if you have tile or hardwood flooring.

3. Are the Dampers Open?

Some ductwork contains dampers to adjust airflow. Look for handles and markings on the ductwork such as ‘summer’ and ‘winter.’ Set the damper handle parallel to the duct line for maximum airflow.

4. Use Foil

If you have a radiator attached to an external wall, use some aluminum foil behind the radiator. The reflective nature of the foil will prevent heat from disappearing through the wall and instead will reflect it back into the room.

5. Try a Fireplace Plug

You can lose up to 20 percent of your home’s warm air through leaks in a loose fireplace damper. A fireplace plug can help you seal the flue to keep that warm air in. Fireplace plugs come in different sizes so be sure you know what size you need before purchasing.

6. Is the Furnace Filter Filthy?

This is the most common cause of heating (and cooling) troubles. Change the filter and the problem usually disappears.

7. Grab a Hot Water Bottle

Tired of getting in a cold bed at night? Fill a hot water bottle (with hot water, of course!) and place it at the foot of your bed, underneath the blanket. It will help keep your feet warm.

8. Let the Sun Shine

During sunny days, open the curtains and let some sunlight in. The rays will help warm you up even on the coldest days.

9. Duct-Booster Fans

If you have forced-air heat, you can take advantage of several types of duct booster fans that are designed to increase the flow of warm (or cool) air through your ducts into a problem room. In-line duct booster fans fit inside standard-size metal ducts. You mount the blower near the outlet end of a duct and then install a pressure switch (some models have one built-in), which senses air pressure from the furnace and turns on the booster fan whenever the furnace or A/C blower turns on. Some in-line duct boosters simply plug into an available outlet, while other models are hard-wired. Cheaper units can be noisy, so it’s worth buying a quality model with a powerful motor and heavier gauge housing.
A ‘register’ booster fan is much easier to install. Depending on the model, it either sits on top of or replaces a floor or wall register grille, and plugs into an outlet. A built-in thermostat switches on when the furnace operates. Register duct boosters cost $40 to $70. Many different manufacturers make duct booster fans of both types.

10. Close the Curtains during the night

If you open the curtains to let the sunshine in during the day, close those curtains at night. This will help you trap the heat inside your home.

11. Leave the Oven Door Open

When you’re done baking and turn the oven off, leave the oven door open. The heat will flow into the kitchen and help warm up the room. Of course, don’t ever do this if you have children, pets or elderly house guests unless you can securely close off the kitchen.

12. Ceiling Fan Heater

This combination light, ceiling fan, and space heater pump out warm air through the ceiling-mounted heater, and the fan blades circulate it throughout the room. During the summer, the unit functions as a conventional ceiling fan.
It’s available in manual and remote control units and can be wired to an existing circuit. The unit is available in a variety of finishes.

13. Try Plastic Wrap with Air Pockets

This plastic wrap is more than just a packing material. Place a sheet on windows you don’t need to see out of to help keep some of that warm air in and cut down on your energy bills.

14. Use Shower Steam

If possible, leave the door open when you shower. This allows all that hot steam to travel through the house. It can also help cut down on dry winter air.

15. Reverse Ceiling Fans

If you have ceiling fans, reverse the motion so they are moving clockwise. This will help move warm air downward where it’s needed to keep you warm.

16. Try a Terra Cotta Heater

Make a terra cotta heater. Just place a terra cotta flower pot upside-down over candles. You’ll need to prop the pot up a little with a couple small rocks or something similar so air can get underneath. Keep the heater out of the reach of children and pets and never leave candles unattended.

17. Cut Down on Mini Drafts

You can lose a lot of warm air through mail slots and doggy doors. When possible, keep these areas covered. You can use a wool blanket to plug an animal door or even an old towel to close up a mail slot when the temperature really drops.

18. Radiant Floor Heat

If you’re already in the market for a remodel, think about radiant floor heating, whether electric or hydronic. Because floor heating has a constant output, you don’t have the large swings (and increased bills) caused by appliances designed to turn off and on again when the temperature drops.

19. Boil a Pot of Water

Whether you use a tea kettle or an open pot, boiling water will help warm up your kitchen. And, when you’ve got that piping hot water, make your favorite tea and warm yourself from the inside.

20. Try a Shelf

If you have adequate open wall space, place a floating shelf above a radiator to help stop the hot air from rising upward too quickly. Just be careful not to put anything on the shelf that could be damaged by the heat.
