Latest posts by Erin Jamieson (see all)

I love attending weddings and following wedding trends. I also love spending time outdoors. What do these two things have to do with each other, and what do they have to do with patio heaters? The truth is many outdoor events- from weddings to gatherings- can quickly go from enjoyable to something to endure when there isn’t ample heating. And for small backyards or more intimate gatherings, one of the best solutions is a patio heater.

Pros and Cons: 48,000 BTU Stainless Steel Patio Heaters

There’s a reason why you’re here. Maybe you’re reading this guide because you’re determined to buy a 48,000 BTU stainless steel patio heater. In that case, feel free to scroll through to my top picks. But if you’re on the fence and still trying to figure out if this is the best patio heating solution for you, here’s my honest opinion.

Reasons to Buy…

48,000 BTU is about as high of heat output as you can get from a standard patio heater. That’s a big plus if you live in a cooler climate. A patio heater with a mere BTU of 20,000 wouldn’t cut it for me on a chilly day in Ohio. Stainless steel is also an excellent choice. Stainless steel is lightweight and versatile but generally weather-resistant. It’s also less expensive than something like stone. 

Reasons to Buy Something Else…

Patio heaters, even at their best, often heat a smaller area than a fire pit. And of course, you can’t use a patio heater to cook or grill as you can with some fire pits. If you’re limited on space, a tabletop patio heater makes more sense. If you live in a climate that only gets slightly cooler, I also don’t think you need a BTU of 48,000. 

Bottom Line…

If you’re sold on a patio heater, 48,000 BTU is about as powerful as you can get, and stainless steel is a lightweight, strong material.

How I find the Best 48,000 BTU Stainless Steel Patio Heaters

Patio Heater

So how did I go about selecting the best value 48,000 BTU stainless steel patio heaters? With the same care, I put into any patio or outdoor upgrades. Here’s what I considered for durability, versatility, and safety. Since we’re focusing on BTU- the more standard unit of measure for gas heaters, the majority of my selections are propane patio heaters. 

Dimensions/ Heating Radius

You won’t find any 48,000 mini patio heaters or tabletop designs. The main options are regular freestanding designs, tall posts, and unique designs like those with side/ connecting tables. I considered all of these options and tried to represent a range of options. For heating radius, I’d expect around 200 square feet, depending on the model. 

Safety Features

I don’t know about you, but I can get forgetful, and I can also be a little clumsy. Those two things taken together, I love finding patio heaters- especially with a higher heat output- with safety features. Those include: 

  • Automatic Shut Off Systems
  • Heat Shields 
  • Anti-Tilt Protection
  • A Sturdy Base 
  • Safety Certifications, such as CSA/CE

None of these are musts- but they do grab my attention. 

Other Features

Other features I considered were all about either extending the use of the patio heater or adding to its aesthetic appeal. To be considered among the best, I wanted each 48,000 BTU stainless steel patio heater I selected to stand out in some way. That included easy transportation (wheels, lightweight design, easy assembly), unique style (bronze, glass tubes), accessories, and adjustable features (including variable temperature). 

I also took note of patio heaters that are easy to use and control, with electric ignition, adjustable knobs, easy access doors, and quick-connect technology. 

Patio Heater Quality and Reputation

To determine overall value, it was also important for me to consider the quality of the construction. While I expect less from budget options, I consider customer satisfaction, reviews, and the reputation of either the brand and/ or the store. Rather than remain brand loyal (though I did consider popular options like Mainstays, Hampton Bay, Living Accents, and Garden Treasures), I selected these patio heaters based on reviews, features, specifications, and even protection plans and warranties. Other features that spoke to me for quality standards included: 

  • Weatherproof Exterior
  • Rust Resistance
  • Blend of other Durable Materials 
  • Thoughtful Construction 

My Picks: Quality 48,000 BTU Stainless Steel Patio Heaters 

With that said, here are a few of my favorite stainless steel patio heaters with a heat output of up to 48,000 BTU. I’ve selected models for different price points, but my main focus was on overall value.

Frequently Asked Questions

Question: What are the hottest patio heaters? 

Answer: 48,000 BTU is about the maximum output you can expect from most commercial patio heaters. For comparison, this is a fair heat output even for a fire pit. Patio heaters with this output frequent best-of lists, but they aren’t always the best solution for every situation. Smaller areas and tabletop heaters are going to fare better with softer heat output. In addition, you should always pay attention to the listed radius of heat coverage to determine the best patio heater solution for your home. 

Question: Can you put a patio heater under a covered porch?

Answer: Patio heaters are often used under covered porches, but this statement requires some nuance. Just because some patio heaters will work safely under a covered porch, does not mean this is universally acceptable. Most patio heaters will include instructions in the manual indicating certain settings you can use under a covered porch- and some may advise against it entirely. You need ample clearance, and likely will need a lower setting. Never operate a patio heater on full heat without consulting the manual. 

Question: Are propane patio heaters worth it?

Answer: Propane patio heaters are efficient and generally easy to use. Over some time, propane patio heaters will save you money over both electric and natural gas heaters. That said, there are a few downsides. Propane patio heaters are generally not as safe as electric heaters- making safety standards and feature more important. They also heat a smaller area of space as opposed to a fire pit. If you want an energy-efficient way to heat a small patio area, then a propane heater is a reasonable option. 

Question: Can outdoor heaters be left out in the rain? 

Answer: Outdoor heaters are sometimes left out in the rain- either because someone forgets or just doesn’t think it will do any harm. Some patio heaters are waterproof, more are water-resistant, and others still will rust or corrode. My general rule of thumb is to play it safe. A simple patio heater cover is an easy solution and should increase the longevity of your patio heater, regardless of the materials it’s purportedly made out of. If you leave a patio heater out in the rain that isn’t made to be weather-proof, you risk ruining it. 

Final Thoughts 

If you’re looking for a patio heating solution, a 48,000 stainless steel patio heater is a wise choice. It’s a good solution for entertaining during cooler months. Stainless steels offer a modern, versatile and durable exterior. Of course, as I’ve discussed, it’s not the ideal solution for every circumstance. If you want to heat just a small area, sometimes a mini patio heater works. If you want a powerful heat source that doubles for entertaining, a backyard fire pit or a fire pit table could be a solution. If you do buy a 48,000 BTU stainless steel patio heater, just make sure you read the description carefully so you understand how large of an area will be covered.

Final Recommendations

If you’re like me, you may mull decisions over for a while before you make a purchase- and that’s fine! Finding the right patio heating solution can take time, and I’d rather you deeply consider it vs rush to buy something. That said, keep in mind that no one patio heating solution is perfect. 

If you’re settled on a 48,000 BTU stainless steel patio heater but just can’t select the best one for you, I recommend the Costway 48,000 BTU Patio Propane Heater if you have the money to spend. With anti-tilt technology, a reinforced base, CSA certification, and some excellent features for entertaining, it’s both versatile and safe to use. If you are on a tight budget, I do think that the Mainstays Large Stainless Steel Patio Heater is a good compromise.
