Other patio heaters we tested

How we tested patio heaters

All of the heaters arrived packed in boxes and required assembly. The level of difficulty was roughly on par with assembling Ikea furniture: there were manuals that occasionally needed a little interpretation. 

Of the traditional-style pole heaters, there was so little variation between the products — from assembly to operation to looks — that they might as well have all come from the same factory. Nevertheless, I followed each set of instructions as they were written to ensure testing accuracy. By the time I got to the last of the pole heaters, I was a pro and it was a breeze. Nothing about the assembly process really stood out, except for the fact that it highlighted the similarities between all of the traditional models. I was, however, pretty happy to see that Amazon sent not one, but two cheap wrenches to aid my efforts. The excitement was short-lived, though, because the pyramid-style heaters were a little trickier to put together.

None of the heaters I tested are going to sweat you out at long distances, but getting up next to one will certainly warm you up. Some manufacturers claim the heater will warm up to eight feet away from the heater, and the results prove that to be true — sort of. All but one heater showed an increased temperature at eight feet away. But keep your coat on, because at that distance we’re talking about only half a degree warmer than the ambient temperature. The warm glow on your face will be nice, but you’re going to need to move closer to the heater’s flame to keep warm on the coldest days. I took temperature measurements at four set elevations relative to the heater’s cap, and 11 equal distances from the heater for a total of 44 points of measurement. Because a patio heater isn’t necessarily made to warm at a distance, the useful range for most of them is about four feet. 

I measured each unit by recording temperatures with a one-dimensional, horizontal array of 11 thermocouples that I moved to four different elevations. The thermocouples, starting one foot away from the burner, are each placed in one-foot intervals. For test equality, the elevation of the thermocouples are determined by the height of the unit being tested: 10, 20, 30 and 40 inches below the unit’s cap. I then compared the temperature at each location to the ambient temperature (also recorded by a thermocouple removed from the reach of the heater’s effect). I don’t have a temperature-controlled environment here at my home in southern Indiana, so I tested all of the heaters in one session, to minimize the difference of the ambient conditions on the test results. In order to get through the tests as quickly as possible I put together a drill-powered system to raise and lower the array of thermocouples to premeasured elevations.

What to consider when buying a patio heater

Coverage area

Most outdoor patio heaters will heat an area to a radius of at least 10 feet, but some can blast warmth a bit farther than that. Determine how much or little space you need to heat on a regular basis. If the area you want to heat extends farther than 10 feet from the heater, you might consider purchasing two heaters.

Style: Pole or pyramid

The two main styles are traditional pole heaters and more modern pyramid-style patio heaters. This is more a matter of taste, but it’s worth noting that the pyramid heaters we tested were slightly more difficult to assemble.

Cost and pricing

Reliable patio heaters start at around $150 and go up from there. The more powerful patio heaters with sleek design elements will cost you closer to $400.

Real-world application

After crunching the data, the Hiland heater emerged as a strong contender. It was one of the hottest models I tested, and when you combine that with the cool visuals of a flame darting up a glass tube, it seemed like a no-brainer.

But then I added an additional step to the test: sitting outside beside each heater on a cooler evening. That revealed something that the thermocouples didn’t: the traditional pole-style heaters give off a much more concentrated heat. When I was sitting next to one, I felt comfortably warm. While the glass tube of the Hiland heater still performs pretty well — and looks neat — having the heat dispersed along the length of the tube simply didn’t warm me up as thoroughly. 

As I mentioned earlier, a lot of the heaters were similar. But when I tested them, it was clear that the Hiland and Amazon model 62516 — despite being nearly identical pyramid-style tube heaters — weren’t alike. The Hiland was one of the best-performing; the Amazon 62516 was one of the worst. Upon inspection, the reason was clear: the only difference was in the regulator controls. That simple variation made all the difference, and it proved true among several of the identical pole heater models, too. 

When all of these heaters appear so similar, it may also be tempting to choose one based on additional accessories. The model from HomeLabs had one that stood out: a table attached to the heater. However, I wouldn’t recommend putting your cold beer on a table attached to a heater.

While it varies by model, you should expect about 10 hours of patio heater use from a single 20-pound tank of propane.&nbsp;

Yes, but there are some clearance guidelines that must be adhered to to ensure safe use of any unit. Those specifications will vary based on the design and power of your patio heater, so be sure to consult the manual before igniting in a covered or enclosed space.

Can you use a patio heater in a covered area?

Yes, but there are some clearance guidelines that must be adhered to to ensure safe use of any unit. Those specifications will vary based on the design and power of your patio heater, so be sure to consult the manual before igniting in a covered or enclosed space.

A patio heater is limited in how large of an outdoor area it can heat. That said, a good patio heater can raise the temperature as much as 25 degrees in its&nbsp;immediate area.&nbsp;
