To heat a room cheaply, consider using a space heater, sealing drafts, insulating windows, utilizing thermal curtains, and maintaining your heating system for optimal efficiency.
Heating costs can drain your wallet fast. But you don’t need to break the bank to stay warm. From infrared panels to simple DIY tricks, here are the most cost-effective heating solutions backed by energy experts.
1. Infrared Heaters (Most Efficient)
Far infrared heaters use 40% less energy than conventional heaters. They work by warming objects directly instead of heating air. This makes them ideal for spot heating.
Why They’re Cheap:
- Use 500-1500 watts vs 1500-3000W for conventional heaters
- Heat persists even when turned off
- No heat loss from drafts
For small spaces, consider electric fireplace logs that combine infrared heating with ambiance.
2. Oil-Filled Radiators
These retain heat exceptionally well. Though slower to warm up, they continue radiating heat long after being turned off.
Cost Comparison:
| Heater Type | Avg. Cost/hr |
|---|---|
| Oil-filled | $0.18 |
| Ceramic | $0.22 |
| Fan heater | $0.25 |

3. Strategic Insulation
Stop heat from escaping before worrying about generating more. These cheap fixes make a big difference:
Window Solutions:
- Plastic shrink film ($0.50/sq ft)
- Thermal curtains ($20-50 per window)
- Bubble wrap (temporary fix)
Door Solutions:
- Install draft stoppers ($5-15)
- Apply weather stripping ($3 per door)
- Hang heavy curtains over exterior doors
4. Reverse Ceiling Fans
Running fans clockwise at low speed pushes warm air down from ceilings. This can make rooms feel 3-4°F warmer without extra heat.
5. Zone Heating Strategy
Only heat occupied spaces. Close doors to unused rooms and focus heat where needed. Pair this with programmable thermostats for maximum savings.
6. Ceramic Space Heaters
While not as efficient as infrared, ceramic heaters offer instant heat at moderate costs. Look for models with:
- Adjustable thermostats
- Tip-over protection
- Oscillation for even heat distribution
7. Thermal Mass Heating
Place heat-retaining objects near heat sources:
- Brick or stone behind wood stoves
- Water jugs near radiators
- Clay pots over candles (emergency heat)
8. Layered Flooring
Up to 10% of heat escapes through floors. Add:
- Thick area rugs ($50-200)
- Carpet padding under existing rugs
- Foam interlocking tiles in basements
9. DIY Heat Reflectors
Place reflective materials behind radiators to direct heat into rooms. Use:
- Aluminum foil ($5/roll)
- Radiator foil panels ($15-30)
- Mylar emergency blankets ($2 each)
10. Strategic Furniture Arrangement
Keep large furniture away from heat sources and exterior walls. This prevents heat blockage and reduces cold drafts.
11. Humidify the Air
Moist air feels warmer than dry air at the same temperature. Increase humidity with:
- Boiling water on stoves
- Open bathroom doors after showers
- Small humidifiers ($20-50)
12. Harness Solar Heat
Open south-facing curtains during sunny hours. Close them at night to trap warmth. Consider solar space heaters for sunrooms.
13. Layer Clothing
Simple but effective. Each clothing layer adds:
- T-shirt: 0.2 clo (warmth unit)
- Sweater: 0.4 clo
- Heavy coat: 1.5 clo
14. Cook at Home
Ovens and stoves add residual heat. Bake during coldest hours and leave the oven door open after use (if safe).
15. Seal Electrical Outlets
Install foam gaskets ($0.10 each) behind outlet covers on exterior walls. This stops cold air infiltration through small gaps.
