Do Space Heaters Work? (Consumers Give Their Verdict About Them)

Do Space Heaters Really Work?

Space heaters are wonderfully affordable, compact, and many of them are also portable however how effective are they with heating a room?

Space heaters work exceptionally well for making a small to medium size room toasty and warm or for taking the chill out of a larger room.

Space heaters are a popular choice for heating small spaces such as bedrooms, living rooms, and home offices. These appliances can be very convenient because they’re portable and can be set up in any room of the house. While they’re typically used for smaller spaces, space heaters can also be used to supplement heat in larger areas.

By using a space heater you can delay starting your main heater as the weather starts to get colder and also turn your main heater off earlier coming out of winter to save wasting money on heating the entire house.

What are Space Heaters Used For?

Space heaters are used for several different reasons, including:

  1. To provide additional warmth to an area that isn’t receiving enough heat through another means (such as the heating system), or is receiving heat but not enough to keep occupants comfortable.
  2. To supplement existing heat sources when the temperature drops below the level that the supplemental heat can provide; and…
  3. To provide supplemental heat to areas where there is no other source of heat, such as basements or attics, which aren’t receiving any heating through other means.

For some people, space heaters can do more than simply make them feel warm; they can also reduce their energy bills. If you need to use your heater for two or more hours each day but don’t want to use more energy than necessary, you should consider purchasing a model with an automatic thermostat that will periodically turn itself off.

Does This Lasko Space Heater Work? Here is what consumers had to say about it…

Works great, excellent room heater! It is smart looking and fits nicely into any decor and does not draw attention to itself. Very quiet, and oscillates nicely and smoothly without any noise.

  • This heater has been with me to 3 apartments lol and has kept me warm every single winter.
  • It works (we used it in the bedroom when it was 15 degrees outside and it kept the bedroom to a nice 75 degrees)
  • Four years of use and the heaters still work just as well as the first day. Extremely energy-efficient, doesn’t make a big difference in the electric bill.
  • BEST HEATER EVER! We love this heater! Seriously, it works better than any others we have had before. Holy COW does it heat up a room!
  • None of the other many heaters I tried have come close to working as well as this particular Lasko model has.
  • One of the best in its class – works perfect right of the Box.
  • To reduce heating bills, this heater has worked great as I am the only one in the house for long periods so it doesn’t make sense to heat the entire house when this heater does a really good job of heating a single room.
  • I really can’t believe how well this works. Warms up our space of almost 600 square feet in no time. I would purchase it again!
  • It’s a small heater and works tremendously well! It’s also very quiet with a minimal amount of hum that emits from the heater. I’ve been using it for 2 years now.
  • I have had this heater for two years now. I use it frequently from November to March. It works flawlessly.

I normally have it in the room I use as an office and it is very quiet, sometimes I forget I have it there! Other times we use it in my daughter’s playroom, and it works great because it does not get hot to the touch, so I don’t have to be concerned about the kids hurting themselves.

  • It has a built-in thermostat.. so it keeps the room at a steady temperature.
  • The heat emitted from these is wonderful and the automatic setting keeps each room you have one in extremely comfortable.
  • This heater is absolutely fantastic. I leave it on all of the time in my nursery to keep the nursery a couple of degrees warmer than the rest of the house since my babies don’t use a blanket and their room doesn’t have as good of vents as the rest of the house.
  • Great heater for my garage, I use two of them in my two-car garage and they keep it nice and warm in the winter.
  • I live in a 40ft camper and bought this heater to use in my living room which is about 15ft x 18ft with the slides out. It will keep the entire area warm on a 40-degree night set at whatever temperature I set it at (normally 72 degrees).
  • My coworkers now migrate to my office to warm up! I am very cold intolerant and the place I work tends to be… cold. I got permission and bought a heater to keep my area warm so I could work without having to wear 2 jackets.
  • Passes the Toddler Test! I am a newborn photographer and use this to keep the area around the baby at a cranking 82 degrees F.
  • It keeps you warm. We have a 300 sqft master bedroom and the heater warmed up the room like a champ.
  • This is the best heater ever. Puts out heat better than any I have owned. I usually keep it by my couch to stay warm while relaxing and watching tv.
  • Great heater for the price. Remote and multiple settings. Keeps a medium to small-sized apartment room nice and warm.

The infrared heater is a more convenient way to heat your home or office without turning on the central heating.
This is one of the most energy-efficient ways to heat your home or business because the heat generated by the unit is directed at people. It doesn’t need vents to release the hot air throughout your home. This means that there is no wasted energy heating empty spaces.

It has been working well all winter. I use it to heat up the bedroom at night, the bathroom when I shower, and take it out to the garage when working in there to warm up the area. So this is great for keeping a single room warm without having to heat the whole house.

  • It is perfect for a bedroom while sleeping at night. No reason to keep the whole house toasty when asleep or at work.
  • I really love this heater! Compared to other heater types I’ve had, the infrared heating element works the best and the blower circulates the warm air very well, even in a space as large as my living room and kitchen.
  • They are smaller than the old-style heaters but throw much more heat. I’ve had them going continuously for months now and they are working great.
  • It’s attractive and it WORKS.
  • Works for us. Saves us lots of bucks, and we stay comfortable up here in cold old N.W. Indiana in our drafty old farmhouse.
  • October to April…it keeps our sleeping area warm and cozy all winter! I thought I’d write this because when I turned it on after sitting all summer, it worked like a charm, and I was reminded how much I love this little heater! Well worth the money!
  • This heater is a workhorse and manages to keep my downstairs very warm. I also found the price to be very reasonable.
  • The Infrared heater works like a charm. The blower is very quiet and sends heat 20 – 30 feet. You can feel the warmth from the heater through our living room/dining room (just one long room, really, about 700 square feet).
  • Have had it for a full year while building & living in my cabin. Works like a champ.
  • Loved this heater so much, we bought another! The one in our great room worked so well (we’ve had it for a long time…want to say a year but don’t recall the exact duration) that we bought one for our master. It works just as well there.

The 1500 watt power rating of this unit means that it can produce sufficient heat in every room of your house or office building without consuming too much electricity. This is one of its main advantages over other units currently available in the market as those typically consume more electricity than portable units due to their higher power ratings compared to those units.

The master bedroom Which we use as an office, not a bedroom, is always FREEZING! I mean attic chill cold. My husband is always wrapped in a blanket while trying to do his job. So, I decided to get a heater for him. Now, for the price, I thought, it will at least heat him right at his seat, which is all he really needs. Uh….. no. This little guy heats the entire room!

  • Bought this for my fiancé who’s a school teacher and is often freezing in her classroom. I tested this heater out before giving it to her and I can tell you this bad boy throws out some heat.
  • Works great and keeps my kid’s room toasty warm!!
  • I have an office that’s around 300 square ft and this heater is ideal, even if I leave my office door open to the hall. I turn it on high and leave it on the first setting for several hours.
  • Great heater for camping and I can definitely see this working for a bedroom or even an office. Easy to carry too.
  • I purchased this to blow hot air at my feet from under my desk while I work, and it’s maybe overkilled for under a desk, even on low. But when positioned 5 or 10 feet away it covers me with an endless supply of wonderfully hot feeling air, feels sorta like sitting in front of a big indoor campfire.
  • Very lightweight and takes up very little space in my work cubicle. I cranked it on high full blast this morning but within an hour or so I had to turn it to a lower setting. I have to say I feel amazing and my quality of life/productivity has improved tremendously at the office.
  • LOVE this one because of the handle at the top. Makes it easy to move around. This one has every feature you could want in a heater and works perfectly!
  • Generates lots of heat! Use it in the bathroom on cold days. Also have used it in the bedroom when watching a movie or hanging out and don’t want to heat the entire house.
  • Even used it as an addition to my regular house heating to heat up the living room quicker. Works great and is super powerful for its small size.

In summary, space heaters certainly do work when using them the way they are designed to be used. Space heaters heat the air around them, and this warmth then radiates throughout a room or house. This means that they should be placed where they can radiate heat away from walls and other obstacles, such as furniture and carpeting.

If you put a space heater in the middle of a room, for example, it will heat the floor and walls, which will then reflect the heat back into the room rather than letting it escape into another part of your home or office.

They are not meant for heating your house but are very effective in smaller rooms such as offices, bedrooms, small apartments, garages, etc.

You can select a personal space heater that is ideal for sitting on or under your office desk or from a space heater that is powerful enough to heat most rooms.

Nonetheless, they do an excellent job!
