The Delonghi HMP1500 is the best spot and room heater

Best Overall
DeLonghi HMP1500

If you want a space heater that does it all, this mica space heater is the one for you. The Delonghi HMP1500 aced our spot-heating and room-heating tests. Our thermal sensors recorded the HMP1500 outputting a maximum temperature of almost 95°F. This Delonghi also raised the temperature of a 1350-cubic-foot room six degrees in an hour, more than enough to warm a chilly room.

Performance aside, the HMP1500 also has design elements that can fit any lifestyle. Users that want their heater to follow them from room to room can install the included wheels. Where stairs are a concern, a handle on the back lets you easily lift the 8-pound frame anywhere. If you have one room in your home that needs supplementary heating, the HMP1500 can be mounted to a wall as a permanent fixture.

Type: Mica

Quick Facts: Wall mountable, wheels included

Safety features: Automatic shut off if tipped over, overheat protection, power/caution indicator lights

Pros

  • Can be wall mounted

  • Easy to move

  • Powerful

Cons

  • Expensive

Best Value
Lasko 754200

When you think personal space heater, the Lasko 75420, a ceramic heater, is what most people typically imagine. It's compact, light, and relatively powerful. However, its power is highly directional. When it's on, you can only heat part of your body. While this Lasko does not have the versatility of our top pick, it's still a good value.

Type: Ceramic fan-forced

Quick facts: Retails for around $30, weighs less than four pounds, has a fan-only setting

Safety features: Automatic overheat protection

Pros

  • Affordable

  • Easy to move

Cons

  • Only works as spot heater

How We Tested

The Tester

Hi, I'm Jon Chan, senior lab technician at Reviewed. The testing team—Kyle, Julia, and I—put all the space heaters through their paces. I first cut my teeth testing heaters on the Dyson Hot+Cool. Playing around with such an expensive heater made me think about what kind of value you can get out of a machine that essentially blows around hot air. My testing philosophy is about finding out which products give the best value.

The Tests

In nutshell, to find the best space heater, we broke down our testing into two categories: performance and usability. To test performance, we placed each heater into a temperature-controlled room, which stayed at 72°F and 50 percent humidity. We know that's not necessarily like your living room or the ideal room you'd heat, but that room is the most temperature stable in our entire laboratory and could help us best test whether or not the room would heat to a desired temperature. During setup, each heater was placed in the center of a 180-square-foot chamber with a 1,350-cubic-foot volume, and plugged into a watt meter.

We then placed two rings of temperature sensors at varying heights to simulate feet and torsos at different distances. These sensors were used to determine spot heating and overall room temperature changes.

Each heater was placed on its highest heat settings and left to run for an hour. After that, we gathered the data from the sensors. Heaters that could evenly heat both the inner and outer rings of sensors received the highest ratings.

What About Safety?

While space heaters are compact and cost-efficient, there is a need for concern. According to the National Fire Protection Association, space heaters are the leading cause of house fires.

All the space heaters we tested had a mechanism built in to shut the device off if it got too hot. Nevertheless, it's recommended to always have a 3-foot radius between a space heater and anything even remotely flammable–including blankets and upholstery.

Also, never plug a space heater into an extension cord. Portable space heaters draw up to 1500 watts of power, more than enough to cause a dangerous spark.

Finally, be sensible and don't touch a space heater when it is in operation. Some portable heaters have a cool exterior when they are running, but that doesn't mean they aren't dangerous. You wouldn't pick up a toaster when it's on, you shouldn't do that with a space heater.

Types of Space Heaters

Space heaters have various heating methods that can affect the size, weight, and other aspects of the product. There are ceramic heaters, fan heaters, oil-filled convection heaters, and some rely on infrared technology. But which one is best for your home? Here's a breakdown of the types we reviewed:

Mica: Thin, energy-efficient, and frequently wall-mountable, mica heaters are part radiant and part convection. They operate silently.

Ceramic Fan-Forced: Convection heaters that blow warm air out from a fan; ceramic space heaters are good for spot heating but not for large rooms. Expect some fan-noise. The plastic shell may be safe to the touch in some models, but the grill is always very hot.

Oil-filled convection: Reminiscent of oil-filled radiators you find in old homes, oil-filled convection heaters work well for entire rooms. They're quiet operation makes it great for living rooms, but they're very hot to the touch on all sides and maybe not the best choice for houses with young children.

Infrared: Sometimes known as "quartz" heaters, these devices don't actually heat the air so much as beam heat directly at you. This is why infrared heaters are often used outdoors, because they are unaffected by wind. Their tops and sides are usually cool to the touch.

Convection Only: Everyone knows hot air rises. Convection heaters simply have a heating element inside a grate. While they are not good for spot heating, they are virtually silent when in operation.

Things to Consider When Purchasing a Space Heater

Before you put a space heater into your virtual or physical shopping cart, make sure that it's a good fit for you and your home by asking yourself these questions:

Location: Do you have an area in your home that is both three feet away from all flammable objects, and is not in the middle of a walking path? If not, see if you can clear a place in your home where the space heater can be safely operated.

Safety: Does part of the space heater get hot to the touch while in operation? If so, make sure that kids are aware of what areas are safe to touch on the space heater, if any. With little ones in the house, it may be best to choose a space heater with a protective grate covering the heating unit.

Floor plan: What is the layout of the room(s) you'd like to heat? If you have an open floor plan, and you'd like to heat more than one room, chances are that a single space heater won't cut it. Space heaters operate best in small spaces and rooms; for large spaces, you may need to safely deploy multiple space heaters in strategic locations throughout your home. If you don't want to buy multiple space heaters, think about picking a space heater that emphasizes whole-room heating over spot heating.

Outlet location: Is there an electrical outlet located near the spot you want the space heater to live? Most space heater power cords are not very long, and it is strongly recommended that space heaters should not be plugged into extension cords. As a safety precaution, do not plug anything into the same outlet into which the space heater is plugged. These heaters use a lot of electricity, so it's best not to overload the outlet.


Other Space Heaters We Tested

Honeywell HCE840B

When it comes to heating a room, we found the Honeywell HeatGenius to be a bit of a savant. Overall, it came in second place in our tests. This ceramic fan-forced Honeywell showed off its smart engineering with how well it utilized its 1500-watt coils. On the one hand, the HeatGenius brought all its air-warming prowess to bear during our spot heating tests. Up close it reached temperatures north of 96°F, hotter than any other heater we tested.

Should you not want to roast, the HeatGenius has phase heating—a feature that lets you bask in warm, moderate, and high heat in 30-minute chunks. We liked the HeatGenius’ performance, but its usability left something to be desired. The controls are bit clunky and complicated. We also found the Delonghi HMP1500 more versatile, able to be wall mounted or moved on wheels.

Type: Ceramic fan-forced

Quick facts: Can be set to warm gradually, 3-year warranty

Safety features: Automatic shutoff if tipped over or after two hours

Pros

  • Can be set to gradually warm

  • Powerful

Cons

  • Can be noisy

DeLonghi EW7707CM

The Delonghi EW7707CM came in third place. This oil-filled convection radiator-style heater had an output max temperature of around 83°F. Over the course of an hour, it brought the temperature in our testing room up three degrees. With these kinds of results, we found that the EW7708CM wasn't as good a personal space heater as the HMP1500. However, you'll sing its virtues if you place it in the basement. Its lowest setting places the EW7707CM on anti-freeze duty, keeping rooms at around 41°F—well north of pipe-bursting temperatures.

While other space heaters we tested could serve the same purpose, the EW7707CM was more energy efficient than the average heater. So, if you're going to keep a heater warming the pipes all winter, this one will dent your wallet the least.

Type: Oil-filled convection

Quick Facts: Has snap-on wheels

Safety features: Automatic overheat shutoff

Pros

  • Good for keeping pipes warm

Cons

  • Not very powerful

LifeSmart 6 Element Infrared

The LifeSmart we tested used six quartz-wrapped elements to produce infrared heat. Using this kind of system helps target the heat and maintain humidity. Our test results lined up with what LifeSmart claimed this heater could do. None of the sensors were directly in the path of the heat elements, so the max temperature recorded was around 77°F. Results like these show that the LifeSmart is good as a personal heater, but not for sharing the warmth.

During the hour we ran this heater, we did not calculate a decrease in the general humidity. You'll appreciate that in the wintertime, when the cold, dry weather is chapping your lips and giving you a sore throat.

While the LifeSmart has premium features like a remote control, its weak room-heating performance makes it hard to justify spending nearly twice what it costs for most other space heaters on the market. Still, if you want a personal heater that won't rob the room of all its moisture, the LifeSmart is worth your consideration.

Type: Infrared

Quick facts: Has a remote control, won't dry out a room

Safety features: Automatic shutoff if tipped over, overheat protection

Pros

  • Good for personal heating

  • Won't lower humidity of room

Cons

  • Does not heat rooms well

Lasko 6435

The Lasko 6435 was the most unique looking space heater we tested. It's only one of two models we tested that could sit on a window sill or a desk, and not look amiss. Where ever you place it, make sure it's close. The 6435 was a better spot heater than anything else. This model also oscillates, meaning it has a motor that waves back and worth, so it can warm up everyone sitting on your couch.

Type: Ceramic Fan-Forced

Quick facts: Looks like a vase, oscillates

Safety features: Overheat protection

Pros

  • Fun design

  • Oscillates

Cons

  • Not very powerful

Delonghi Capsule

The DeLonghi Capsule made the list of Oprah’s favorite things, so we just had to check it out. Compact, well designed, and powerful, the Capsule nearly toppled our old pick for best value. However, it’s about 30 percent more expensive than the Lasko 754200, but only 6.5 percent more powerful. We’d suggest that you get this one if you constantly moving your heater from place to place. We found the Capsule’s strap handle very comfortable to use.

Type: Ceramic Fan-Forced

Quick facts: Strap handle, one of Oprah's favorite things

Safety features: Overheat protection, automatic shutoff if tipped over

Pros

  • Easy to carry

  • Powerful

Cons

  • Expensive

Dr Infrared Heater DR-968

The Dr Infrared uses the same quartz heating elements as the LifeSmart. While the doctor was more powerful, it didn't do as well at spreading the heat around the room. During testing, we also noticed that this model dried out the air more than the other infrared heaters. When you combine these two negatives, even the lower price tag keeps the Dr Infrared from claiming a top spot.

Type: Infrared

Quick facts: Has wheels, uses radiant heat

Safety features: Automatic shutoff if tipped over, overheat protection

Pros

  • Good personal heater

Cons

  • Does not heat rooms well

Lasko 5622

As wide as the Lasko 5622 is, the path of its warmth isn't actually that great. The outer ring of our sensors barely registered any heat. The sweet spot is dead center, and you could get smaller space heaters for that. The 5622's saving grace is that it works right out of the box. Most space heaters in this size range require you to install legs or wheels.

Type: Convection

Quick facts: No assembly required, also comes in black

Safety features: Automatic shutoff if tipped over, overheat protection

Pros

  • Low-to-the-ground design is unobtrusive

Cons

  • Not very powerful

  • Difficult to move

Dyson Hot+Cool Jet Focus AM09

The Dyson AM09 Hot+Cool impressed us with its design. In our usability tests, the AM09 blew several competitors out of the water. First, it was the most pet and kid friendly heater we tested. This Dyson has no exposed heating element, making way safer for tiny hands and paws. We also like the magnetic remote that sticks to the top of the unit so you never loose it. Finally, the Cool part of Hot+Cool comes from the fact that it also acts as a powerful fan in the summer time.

As much as we liked the AM09’s design, we felt much more lukewarm about its heating performance, especially in light of its large price tag. Its spot-heating capabilities proved adequate, but its ability to heat a room fell behind the pack. After an hour, it turned a 72°F room into a 74°F room.

Type: Ceramic Fan-Forced

Quick facts: Has a powerful fan, oscillates

Safety features: No exposed heating elements, automatic shutoff if tipped over

Pros

  • Pet and kid friendly

  • Also works as a fan

Cons

  • Expensive

Lasko 755320

Where the 5622 was the widest heater we tested, the Lasko 755320 is the tallest. Standing nearly 2-feet tall, the 755320 is known as a tower heater and boasts the same design as a tower fan. It oscillates like one, too.

During testing, we liked how the handle on the back made it easy to move this Lasko from room to room. However, its performance is lackluster compared to other heaters on this list. Even with the oscillation on, we found that the sides of our testing room did not get warm.

Type: Ceramic Fan-Forced

Quick facts: 23 inches tall, oscillates

Safety features: Overheat protection

Pros

  • Easy to move

  • Oscillates

Cons

  • Not very powerful

Honeywell HCE200B

With a heater as small as the Honeywell UberHeat spot heating is a must. While, this little heater didn’t stack up as well as the Lasko 754200, it did alright, raising the temperature a foot away to 74°F.

Where the UberHeat lagged behind in performance, it made up for in looks. A lot space heaters out there look bulky and misshapen, but this Honeywell’s design makes sit appear that it belongs on a tidy desk or nightstand.

Type: Ceramic Fan-Forced

Quick facts: Looks like a radio, 3-year warranty

Safety features: Overheat protection

Pros

  • Fun design

Cons

  • Not very powerful

Mill SG1500LED

Mills makes some of the best-looking space heaters around. The SG1500LED is no exception. Its excellent design went beyond looks: The Mills also has good controls. Our favorite aspect was the ability to set two temperature settings, one for day time and the other for when the sun goes down. However, its performance disappointed us. After an hour, the SG1500LED barely raised the temperature of the room two degrees. Our couch-height sensors also registered little to no change.

Type: Convection

Quick facts: Very elegant looking, some assembly required

Safety features: Automatic shutoff if tipped over, overheat protection

Pros

  • Elegant design

Cons

  • Not very powerful

Mill AB-H1000DN

The oil-filled Mills AB-H1000DN suffers from the same problems as its electric cousin. This heater is a better looker than performer. While it was energy efficient, it barely produced enough heat to register on any of our sensors.

Type: Oil-filled convection

Quick facts: Very elegant looking

Safety features: Automatic shutoff if tipped over, overheat protection

Pros

  • Elegant design

Cons

  • Not very powerful
