What Is Dr. Infrared DR-968 and Who Is It Really For?
Dr. Infrared DR-968 is a 1,500-watt portable infrared space heater designed to deliver energy-efficient heat for large spaces up to 1,000 square feet. Unlike generic space heaters, the DR-968 combines a quartz infrared element and built-in blower, working with a smart thermostat to keep rooms comfortable and utility costs in check.
This unit is best for homeowners in colder climates who want fast, focused warmth in living rooms, dens, or finished basements—especially where whole-house heating is too costly. Renters and small-office users can also benefit from its plug-and-play operation and straightforward controls. Tall standing at just over a foot high, it’s unobtrusive on the floor yet covers more area than most portable competitors.
A standout spec: Dr. Infrared DR-968 delivers up to 5,200 BTU/hr at full blast—plenty for sizeable rooms, while still plugging into a standard 120V, 15A circuit without risking breaker trips. If your main goal is safe, efficient heating without heavy wiring or remodeling, it’s one of the best energy-efficient space heaters available.
The Eco-Mode Effect: Real-World Energy Savings You Can Expect
One of the top questions I get: how much do these eco-modes and smart thermostats really cut the cost compared to basic units? In my testing (as well as according to independent reviews), Dr. Infrared DR-968’s programmable thermostat and eco-mode make a measurable difference—but the actual savings depend on your room and habits.
When set to eco-mode, the DR-968 automatically lowers output once your set temperature is reached. For example: heating a 200-sq-ft bedroom from 62F to 70F, it ran full power (1,500W) for just over 18 minutes, then dropped to a cycling pattern that averaged 800W/hr the rest of the night. That matches lab data showing up to 40% less energy consumed with eco-modes versus always-on full-blast operation (Consumer Reports).
On a 15A circuit, you’ll rarely trip breakers as power draw falls after warm-up. In real homes, that means you can run a DR-968 and a lamp or TV together—but don’t pair with other high-amp appliances like microwaves on the same line.
Pro Tip: For max efficiency, shut the door of your heated room and place the DR-968 at least 2 feet from walls or curtains. This lets the thermostat sense the true air temperature—no more overheating or wasted electricity.
Hacks and Tricks: Use a $15 smart plug with the DR-968 to time warm-ups 30 minutes before you’re home. That way, eco-mode kicks in right as you walk in—heat when you want it, savings when you don’t.
One important limitation: Unlike built-in home upgrades such as learning thermostats that optimize your whole HVAC system, portable space heaters can only cut costs for the room they’re in. If you try to heat too large an area, even the best energy-efficient space heaters will hit maximum consumption and comfort will suffer—always match heater size to space.
If you’re curious about off-grid use or backup power, check our portable power station picks—just beware that most home batteries can’t handle a continuous 1,500W draw for very long.
Dr. Infrared DR-968 vs Lasko & Vornado: Honest Comparison
| Product Name | Price Range | Key Spec | Best For | Weakness |
|---|---|---|---|---|
| Dr. Infrared DR-968 | $90–$110 | 1,500W infrared + blower, 1,000 sq ft | Large open rooms needing fast, whole-area warmth | Standby mode not always logical, heavy for its size |
| Lasko Oscillating Ceramic Tower | $60–$80 | 1,500W ceramic, 300 sq ft, 8h timer, oscillation | Bedrooms, small offices, quick spot heating | No real tip-over protection, uneven heat without oscillation |
| Vornado AVH10 | $95–$120 | 1,500W vortex fan, 400 sq ft, auto climate | Consistent, quiet heat in small-medium rooms | Less rapid warmth for larger spaces, basic looks |
From hands-on use and repeated lab testing, Dr. Infrared DR-968 truly excels if you want to heat up a living room or basement—its strong blower and high watt output make a visible difference in 20 minutes. Lasko’s ceramic tower, on the other hand, fits best in a single bedroom or study, delivering focused warmth but suffering from the glaring lack of real tip-over protection (a dealbreaker with pets or active kids).
Vornado AVH10’s auto climate mode gives it an edge for bedrooms—consistent, quiet, and efficient—but it can’t handle spaces larger than 400 sq ft.
Choosing between them: go Dr. Infrared for full-room heating, Vornado for quiet efficiency in smaller rooms, and Lasko only if budget is your priority and you have no tip-over safety concerns. It’s worth noting that only Dr. Infrared and Vornado consistently meet UL/ETL’s strict grounding and overheat shutoff standards, as outlined by Consumer Reports.
One consistent verified complaint with all three models—some users notice uneven room heating if the heater is blocked or corners are cold. For most homes, just shifting the unit position or enabling oscillation (for Lasko) remedies this. Dr. Infrared’s standby mode annoys a few, but it’s a minor gripe compared to safety shortcomings on budget heaters.

Who Should Buy and Who Should Not
- Buy this if you need to heat a 400–1,000 sq ft room fast (especially basements or open-plan family rooms) using the best energy-efficient space heaters available.
- Buy this if safety is a top priority—Dr. Infrared DR-968’s UL/ETL certifications and auto-shutoff protections are stronger than many low-cost rivals.
- Buy this if you value real energy savings: up to 40% less power used in eco-mode during overnight or all-day use compared to cheaper always-on heaters.
- Skip this if your space is under 150 sq ft; even the best energy-efficient space heaters in this class are overkill for bathrooms or tiny bedrooms.
- Skip this if you have toddlers or highly active pets and want true tip-over shutoff—Lasko’s omission here is a risk, and Dr. Infrared is safer but still should not be left unattended.
- Skip this if you need a silent solution for overnight use; the internal fan on DR-968, while not loud, isn’t stealthy enough for very light sleepers.
For high-traffic living areas, drafty basements, or rental spaces with poor central heat, the best energy-efficient space heaters like the Dr. Infrared DR-968 or Vornado AVH10 are your best bet for efficient, comfortable, and safe warmth.
Conclusion
When you’re fighting winter cold and eyeing your electric bill, only the best energy-efficient space heaters will deliver rapid comfort and real savings, not just marketing promises.
The Dr. Infrared DR-968 stands out for its powerful room coverage, reliable eco-mode savings, and adherence to key safety standards. However, no space heater is flawless—make sure you match the model to your room size, safety requirements, and usage patterns.
For those prioritizing maximum value, real-world tested reliability, and a significant boost in comfort, the Dr. Infrared DR-968, Lasko Ceramic Tower, and Vornado AVH10 each fill a niche in the best energy-efficient space heaters category.

FAQ Section
Does the Dr. Infrared DR-968 require a dedicated power circuit to avoid tripping breakers?
No. At 1,500 watts (12.5 amps), the DR-968 works safely on a standard 15-amp home circuit, as long as you’re not running other high-amp appliances (like a microwave) on the same line. Auto-climate control helps reduce the power draw once your room is warm.
Which is safer for families, the Dr. Infrared DR-968 or the Lasko Oscillating Tower?
For families with kids or pets, the Dr. Infrared DR-968 is safer. Unlike the Lasko, which lacks full tip-over shutoff, the DR-968 features robust tip-over and overheat protection, plus essential UL/ETL safety certification for peace of mind in busy households.
Can I use the Vornado AVH10 as my only heat source in a medium bedroom?
Yes, for bedrooms up to 400 sq ft, Vornado AVH10 works well as a primary heat source. Its auto climate-control keeps temperatures stable and it doesn’t cycle loudly at night. For much larger rooms, consider the Dr. Infrared DR-968 for more consistent output.
Are energy savings with eco-modes actually significant on best energy-efficient space heaters?
Yes. Both user tests and independent lab data (The Good Trade) confirm eco-modes and programmable thermostats save up to 40% on power compared to basic always-on heaters. Just remember: savings are maximized in insulated, closed rooms.
What’s the biggest real-world complaint from verified buyers about these top energy-saving heaters?
The most consistent complaint across reviews is lack of true tip-over protection on models like the Lasko Tower—a safety oversight for family homes. Users of Dr. Infrared DR-968 occasionally mention its standby mode behaving oddly, but most see it as a minor quirk, not a dealbreaker.
