What are the best patio heaters? Propane models are more economical and portable in comparison with electric ones. There are freestanding heaters that you can place wherever you want as they do not require a power outlet. The downside is that they run out of fuel so you should have an extra tank at hand. Opt for the models with the heat output of approximately 40,000 BTU’s per hour. They are powerful enough to warm up an area of 20 feet, but not too much to make the device run out of gas very quickly. We believe that Fire Sense Patio Heater meets all these criteria best.

We all know lots of people who love spending their leisure time in their patio and read their favorite books there, spend time with their guests or throw BBQ parties there.

The summer is about to be over, a warm blanket is not going to be helpful in a while, so you are probably looking for patio heater.

We have selected 9 best outdoor patio heaters, ranging from compact designs for 1-2 persons to more powerful ones for a large company or bars and restaurants. Which one will you pick: a portable or full size one, table, floor, or hanging, electric or propane powered heater, or maybe even, patio fire pit?

Best Patio Heaters: Types | How it Works

To pick a proper patio heater you have to first figure out how heaters work in general. Space heaters, including pation heaters specifically are classified in two types based on the heating method:

  • convection (they use air surrounding the device for heating) - propane patio heaters;
  • radiant heating (infra-red radiation directly heats objects and people within the device’s action radius) - electric patio heaters.

Gas (propane) heaters lead the outdoor heaters market while the electric patio heaters follow them.

All of the propane heaters are rated with an AFUE. This efficiency rating indicates the percentage of the useful heat generated from 100% of fuel consumed. The greater the heat output (Btu / hr) is, the greater is the efficiency.

Another measurement that you have to consider when choosing a patio heater is the BTU (British Thermal Unit) per hour that’s used to describe the power capacity of heating appliances. BTU, in its essence, measures the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit. To determine BTU/hr of a particular space, you have to multiple 20 BTU by one square foot. For ease of use, hereinbelow, you’ll find a table with calculations of BTU for the most standard areas.

BTU will help you determine how much heat is needed for your particular space: it’s important to choose a patio heater that has an adequate heat output for the space that you have. In simpler terms, you wouldn’t want to buy something that doesn’t heat up all the area, just as you wouldn’t want to buy something too huge for a small space. Bear in mind, that if you live in a windy area, the inflow of cold air can affect the patio heater’s efficiency. With that being said, you would want to consider a higher BTU for a climate like this.

Propane heaters are handier for long-term heating, while the electric models are more effective when used only for several hours, as the University of Alaska Fairbank scientists claim. In any case, it’s up to you to choose, we’ll only describe you the best models we’ve studied and will help you pick a powerful heater for a large patio as well as a portable patio heater for 1-2 persons.

3 Best Floor Standing Heaters for a Large Patio and Your Entire Squad

To heat a large patio, you need to choose a powerful floor model with high thermal power output, preferably from 40,000 Btu/hr and up. This ensures that the rate of the heat generated will be sufficient to keep warm even a big company chilling on a large patio. Only propane devices marked "commercial" will cope with the task as they can also be used in outdoor cafes and restaurants.

Still, bear in mind that there is a relationship between the heat output (Btu/hr) and the operating time of the heater on a standard 20lb gas tank. The more the heater’s Btu/hr is, the greater the heating area is and the sooner you’ll be running out of gas.

«I work from my home office that's my garage and been freezing..space heaters didn't not work so I stepped my game up! My space is 24x22 and now it's almost to HOT! It's WELL».

«This thing is really tall. I cut 12" off the upper steel support post, re-drilled holes, and it now puts out at least 10x more heat on me where before it was almost useless in sub-zero temperatures. Installation is easy and common sense, there are only like 10 parts, I have no idea why people are complaining about this».

«I decided to lower the top tubing by 4 inches. Holy Mother - what a difference, easily twice as warm. Keeping the unit at the open front created a kind-of heat wall that really slowed the cold from getting in. Sitting in chairs the whole space started warming up. (10x12). I own the tools to cut the steel tubing and redrill the mount holes. The conclusion is get the shorter version unless it's used for a "standing" only area. I'm 6' 2" and this one 4" shorter is perfect now».
