You can’t stop the seasons from changing, but you can make your outdoor space enjoyable year-round with the help of our outdoor patio heater buying guide.
Patio heaters are useful outdoor accessories that can make your patio nice and toasty even during cold autumn and winter months. They also serve a decorative purpose, giving your outdoor setup a cozy flair and romantic ambiance.
But with so many patio heaters out there, deciding which type is best for your needs isn’t easy. In this guide, we break down all the important selection criteria to which you should pay attention when selecting your first patio heater.
Before we tell you what styles of patio heaters are available, we want you to understand how patio heaters work and what makes them different from household radiators and electric space heaters.
Patio heaters produce radiant heat, which warms people and objects the way the Sun warms the Earth. Rather than heating the air, infrared waves heat everything in their path. On the other hand, household radiators and electric space heaters rely on the movement of air molecules to transfer heat from one place to another, a process known as convection.
Radiant heat is great outdoors because it basically makes you feel as if the Sun was shining directly at you, gently showering you with rays of warmth. Because it doesn’t rely on air movement to spread the warmth, it works even without a ventilator, which is why most patio heaters don’t have one in the first place.
Patio heaters are typically categorized by the type of fuel they use:
The heat output of patio heaters is measured in British Thermal Units, or BTUs for short. This traditional unit of heat is defined as the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit.
To calculate how many BTUs you need, multiply the volume of your space, measured in cubic feet, by the desired temperature rise. For example, it takes 25,000 BTUs to raise the temperature of an area that measures 10 x 10 x 10 feet from 60 degrees Fahrenheit to 85 degrees Fahrenheit.
Patio heaters produce anywhere from 10,000 BTU to 70,000 BTU and more, and you can, of course, place more than one in the same space. Keep in mind that manufacturers always measure the efficiency of their products under ideal conditions, which means low humidity and little to no wind, so don’t forget to take your local weather conditions into consideration as well.
Different styles of patio heaters are suitable for different applications:
Modern patio heaters are equipped with many safety features that keep them safe:
Patio heaters with a powder coating require minimal maintenance, apart from the occasional wipe down. Stainless steel patio heaters are best cleaned with a stainless steel cleaner and a gentle brush. From time to time, you should remove dead insects from your patio heater and check for mechanical damage.
Outdoor patio heaters come in many shapes, sizes, and types. In this guide, we’ve explained all the important selection criteria to which you should pay attention when selecting your first patio heater, including heat and fuel types, heat output, patio styles, and safety features.
