Should Decision-Makers Think About Residential Infrared Gas Heaters In Terms of Rectangles & Circles?
5 minute read | Heaters

With so many heater options and aggressive marketing campaigns, choosing the right commercial or residential infrared gas heater for patio comfort can be overwhelming. The promise of a wide heat coverage area often makes it hard to decide between a portable LP heater or a natural gas model. Comparing heat output and square footage numbers can leave homeowners and business owners feeling lost in the details.
If you're looking to simplify your decision-making process, consider that most heaters fall into two basic shapes—rectangular or circular. While this might sound like an oversimplification, it’s actually a useful way to understand how different models work and where they are best suited.
Take a look around any restaurant patio or backyard deck, and you’ll likely spot the iconic mushroom-shaped heater. These round, portable LP heaters are among the most popular for outdoor use. On the other hand, rectangular suspended heaters are commonly found above verandas, patios, and open-air spaces. Whether you’re looking for a compact solution or something more permanent, understanding these design differences can help you make a better choice.
The key is not just the shape but also how each heater functions in its environment. Rectangular heaters are ideal for fixed installations, while circular models offer flexibility and portability. Let’s dive deeper into both types and see which one might suit your needs best.
Why Choose a Rectangular Infrared Heater?
Rectangular infrared heaters, often referred to as box heaters, are a popular choice for semi-enclosed spaces such as verandas, patios, and even indoor areas. Their design allows for various mounting options, making them versatile for both residential and commercial use. They are especially effective when installed overhead, on walls, or even flush with ceilings or walls, offering a clean and efficient heating solution.
These heaters typically use quartz or ceramic elements to generate heat and come in a variety of colors and finishes, allowing them to blend seamlessly into different settings. They can run on LP, natural gas, or electricity, giving users more flexibility based on their available infrastructure. Some models even allow for multiple units to be controlled from a single panel, making them ideal for larger spaces.
One of the biggest advantages of rectangular heaters is their ability to provide consistent warmth over a targeted area. Unlike traditional heating systems that warm the air, infrared heaters directly heat objects and people, making them more energy-efficient and cost-effective in the long run.
Why Choose a Circular Portable LP Heater?
Circular or mushroom-shaped heaters are known for their 360-degree heat distribution, making them perfect for open areas where flexibility is key. These heaters are often used on patios, decks, and outdoor gathering spots, thanks to their portability and ease of repositioning. Many models feature a base that houses the fuel tank, making them easy to move and refill as needed.
While they have fewer mounting options compared to rectangular heaters, they still offer versatility. They can be mounted on poles or suspended overhead, depending on the model. This makes them a great choice for those who want to adjust their heating setup based on the number of guests or seating arrangements.
Another benefit of circular heaters is their ability to provide immediate warmth without affecting the surrounding air temperature. This makes them ideal for short-term use or in areas where heating the air isn’t necessary.
How to Choose Between the Two
When deciding between a rectangular or circular infrared heater, consider your specific needs. If you need a permanent, space-efficient solution with multiple mounting options, a rectangular heater may be the way to go. However, if you prefer mobility and the ability to reposition your heater, a circular model could be more suitable.
Also, think about the fuel source. Rectangular heaters can often be powered by LP, natural gas, or electricity, while circular models are usually propane-based. Make sure you have the necessary infrastructure in place before making a purchase.
Ultimately, whether you choose a rectangular or circular heater depends on your space, budget, and usage requirements. Both types can be part of a larger heating system, offering comfort and efficiency in different ways.
