Our Verdict

Earning the Editors' Choice award for Best Tower Style, the Lasko 755320 is a fantastic option if you want a model that provides superb performance but also offers a variety of settings and features along with a sleek look. Its heating capabilities are phenomenal — this heater would be a great choice for under your desk or in your living room. We love how easy the remote is to understand and use, and as an added bonus it fits comfortably in your hand. A considerable element of tower-style space heaters is that they take up very little floor space as opposed to their wider, stockier cousins.

Our Analysis and Test Results

Above all, the reason that the Lasko 755320 laid claim to an Editors' Choice award is its ability to heat up a small area, and get it done fast. As soon as you turn this device on it begins raising the temps in the immediate vicinity, and before long it warms up the entire room at a rate on par with the best space heaters that we've seen.

Performance Comparison

Personal Heat

Because the most common use of a space heater is to warm up a small area in order to make a person more comfortable, the first assessment that we conducted was to see how well each model performed in this aspect. We subjectively judged each model warming capabilities both under a desk as well as in a living room 5 feet away from a recliner.

The Lasko 755320 was one of the highest performing space heaters for personal heating that we've reviewed. This model was even what we would consider to be a little too intense under a desk on its highest settings.

When we tested this model in a living room setting, it was easy to feel the airflow while sitting down several feet away.

Many factors play into how convenient a space heater is to use. These devices can come as simple and bare-bones as can be, or they can come with a multitude of features and settings. For this metric, we carefully studied every tiny detail of each model down to how intuitive the symbols on the buttons of the remote control are. The 755320 was one of our top-scoring space heaters for this assessment.

The Lasko 755320 comes with an oscillating feature that helps disperse heat throughout an area as opposed to a stationary style heater. This model also has a timer that goes up to 8 hours in 1-hour increments.

Several of the heaters that we've gotten our hands on have the option to crank the heat to 90 degrees or more, and the 755320 is no exception — however one thing that we found especially innovative about the Lasko is that it has temperature settings that go all the way down to 39 degrees. While it may not be intuitive to desire conditions with that low of a level of warmth, sometimes the only reason you need a space heater is to keep pipes, liquids, or other belongings from freezing. If that's the case it would be an awful waste of energy to be heating the area to anything much higher than a few notches above 32 degrees.

The remote included with the Lasko 755320 was one of our favorites in the review. It fits well in your hand, it's stylish, and it's fairly obvious what the symbols are trying to convey.

Small Room

For our next set of experiments, we measured how much each model could raise the temperature in a 161 square foot room, checking on the readings once every twenty minutes up to an hour. We were sure to start the assessment with the room temperature within a degree or two for each model. Also, we didn't want the temperatures outside the window of the room to affect the assessment, so we waited for a cold spell in order to make sure the outside temps were right around freezing.

This test showed fairly strong results for the 755320. This model was able to raise the temperature 6.4 degrees Fahrenheit in the first 20 minutes and produced a total of 10.8 degrees of increased warmth after a full hour.

Power Consumption

To calculate the dollar amount that it takes to run each heater we used a wattmeter to measure the amount of power the devices consumed per hour over a two hour period. We were then able to determine how much it costs to run each model for 10 hours, 24 hours, 30 days and so on using the national average price of kilowatts per hour.

Regrettably, the Lasko 755320 is not the most efficient space heater that we've tested. It uses a measured amount of 1.36 kilowatts per hour which translates to $1.79 over a 10 hour period to run this space heater on its highest setting at 13.17 cents per kilowatt-hour. That may not seem like much, but over a month of running the 755320 for 10 hours a day, it's going to cost more than $50 to run this space heater. That said, depending on your current heating system efficiency, it may save you money to run a space heater in the room you are using rather than heat the whole house or office.


The Lasko 755320 offers a great deal of performance at a moderate price. We think this model is well worth its price and is a good value, especially if you want a powerful heater.


The Lasko 755320 was one of the best all around space heaters that we have tested. It performed well when it came to heating an office space, a living room, and a small room. We found that many features included on this model add to its convenience including its digital display, ergonomic remote control, and oscillation setting. The only main drawback we could find with the 755320 is that it is a bit inefficient and expensive to run, but that's to be expected with a heater this powerful.
