Best Room Heaters 2025: Buyer's Guide & Picks

Looking for the best room heater to keep your space warm without blowing your budget?

You’re in the right place—below you’ll find our top picks across different heater types, plus a simple guide to choosing the right size, features, and safety protections.

How to Choose the Right Room Heater

Before you buy, match the heater to your space and needs. As a rule of thumb, a 1,500-watt portable heater can deliver roughly 5,100 BTU, which is typically enough for a small to mid-size room (about 150–250 square feet) when used as a spot heater. Larger rooms or poor insulation may require multiple units or a different heating approach.

Consider the heat delivery method: ceramic and fan-forced models heat up rooms quickly, oil-filled radiators provide quieter, more even warmth that lingers after shutoff, and infrared units warm people and objects directly with less air convection—useful in drafty areas.

Safety matters. Look for tip-over and overheat protection, a sturdy base, and if possible, a cool-touch exterior. For bedrooms or offices, check noise levels and seek models with thermostats and eco modes to avoid overheating and manage energy costs. For a refresher on safe use, see the U.S. Department of Energy’s guide to portable heaters.

  • Ceramic/fan-forced: Quick warmth, compact, often the best value.
  • Oil-filled radiator: Very quiet, steady heat, great for bedrooms and nurseries.
  • Infrared/quartz: Efficient for spot heating people and objects, good in drafty spaces.
  • Tower and panel heaters: Slim, space-saving profiles with widespread oscillation (tower) or gentle radiant warmth (panel).

Top Picks: Best Room Heaters for 2025

Vornado AVH10 Vortex Heater — Best All-Around for Most Rooms

The AVH10 uses Vornado’s vortex circulation to move warm air evenly without feeling like a direct blast. It heats small-to-mid rooms quickly, maintains steady temperatures thanks to an accurate thermostat, and includes a cool-touch exterior.

  • Best for: Bedrooms, living rooms, home offices up to ~250 sq. ft.
  • Why we like it: Even heat distribution, reliable thermostat, strong safety features.
  • Consider if: You want faster, room-wide warmth with fan circulation.

Lasko 755320 Ceramic Tower Heater — Best Budget Tower

This popular tower offers two heat settings, widespread oscillation, a built-in timer, and a remote—often at a wallet-friendly price. It’s lightweight, easy to move, and provides quick, even heating for small and mid-size rooms.

  • Best for: Apartments, dorms, and small living areas where floor space is tight.
  • Why we like it: Great value, oscillation, simple controls, remote included.
  • Consider if: You prefer a tall, slim heater with fast warm-up and handy features.

De’Longhi Oil-Filled Radiator (TRD series) — Quietest for Bedrooms

Oil-filled radiators like De’Longhi’s TRD series shine for whisper-quiet, consistent warmth that persists after shutoff. They’re heavier than fan heaters but excel in maintaining comfortable, stable temperatures overnight.

  • Best for: Bedrooms, nurseries, and anyone sensitive to noise.
  • Why we like it: Silent operation, steady radiant heat, built-in overheat protection.
  • Consider if: You can trade a slower warm-up for better comfort and quieter nights.

Dyson Hot+Cool AM09 — Premium Heat + Year-Round Fan

Dyson’s bladeless design is safe and easy to clean, offering focused heat in winter and smooth airflow in summer. The AM09’s precise thermostat and even distribution make it a luxe, do-it-all choice—though it’s priced accordingly.

  • Best for: Design-forward spaces where a single device serves multiple seasons.
  • Why we like it: Year-round utility, stable temps, quiet operation.
  • Consider if: You want premium build and aesthetics with versatile performance.

Dr. Infrared Heater DR-968 — Best for Drafty Rooms

The DR-968 uses infrared quartz elements plus a fan to warm objects and people directly, which helps in drafty rooms or larger spaces. It’s housed like a small cabinet on casters for easy movement.

  • Best for: Draft-prone living rooms or open floor plans needing targeted comfort.
  • Why we like it: Strong heat output with comfortable, less-drying warmth.
  • Consider if: You want a mix of infrared and convection that feels natural.

Slim Panel Heater (De’Longhi SlimStyle) — Best Low-Profile Heater

Slim panel heaters tuck neatly against a wall or baseboard and blend into decor. De’Longhi’s SlimStyle line offers gentle, even warmth with a shallow depth—great where space is at a premium.

  • Best for: Hallways, studios, and minimalist rooms.
  • Why we like it: Discreet profile, steady heat, simple controls.
  • Consider if: You prefer gentle background warmth over rapid heat-up.

Honeywell UberHeat HCE200 — Best Personal/Desk Heater

Compact and focused, the UberHeat is ideal for under the desk or at a reading nook. It’s simple, capable, and portable—perfect when you only need to warm yourself, not the entire room.

  • Best for: Personal warmth at a desk or bedside.
  • Why we like it: Small footprint, quick heat, easy to stash.
  • Consider if: You want targeted comfort without running whole-room heat.

Sizing, Efficiency, and Cost-to-Run

Match output to the room: Most portable space heaters draw up to 1,500 watts on high. For quick mental math, assume 10 watts per square foot in a reasonably insulated room. Example: a 180 sq. ft. office ≈ 1,800 watts equivalent; a single 1,500-watt heater will warm your immediate area but may not fully replace central heat.

Estimate operating cost: Cost ≈ (watts/1,000) × hours × electricity rate. If your rate is $0.16/kWh, running a 1,500-watt heater for 4 hours costs about (1.5 × 4 × $0.16) = ~$0.96. Use a lower setting or thermostat/eco mode to save.

Boost efficiency: Close doors, seal drafts, use a small fan to gently circulate heat, and place the heater on the floor in the coldest part of the room (away from curtains or bedding). For more tips, see the DOE’s portable heater guidance.

Essential Safety Tips

  • Keep a clear 3-foot zone around heaters; never drape clothing or towels over them.
  • Plug directly into a wall outlet—avoid power strips and extension cords.
  • Choose models with tip-over and overheat shutoff. Look for UL/ETL certification.
  • Place on a flat, stable surface; avoid thick carpets that can restrict airflow.
  • Turn off when you leave the room or go to sleep unless the manufacturer explicitly states it’s safe for unattended use.
  • Keep away from water sources; use bathroom-safe models only where permitted.

For authoritative guidance, check the Consumer Product Safety Commission’s portable heater safety center and the NFPA’s heating safety tips.

Quick Recommendations by Scenario

  • Fast warmth in a living room: Vornado AVH10 or Lasko 755320.
  • Silent overnight heat in a bedroom: De’Longhi oil-filled radiator.
  • Drafty, open areas: Dr. Infrared Heater DR-968.
  • Minimalist spaces: Slim panel heater (De’Longhi SlimStyle).
