A patio, balcony, rooftop or garden can feel like your home’s got an additional room. With an outdoor heater, it’s a room you can use all year round! From heat output to fuel, here’s what you need to know.

The heat output of an outdoor heater is usually measured in BTU. This stands for British Thermal Unit—although is also used in the USA. Most outdoor heaters have an output that ranges from around 5,000BTU to over 40,000BTU and, as you might expect, the higher the output, the larger the space the heater can effectively warm.

The type of heater that you get will depend on the space that you have available to you and your needs. Many commercial spaces will use umbrella style heaters because the heating element is safely away from customers, but for smaller spaces and home use, you might find it more economical to use a floor-level heater. There are also models that fall somewhere in between, or are adjustable in height so you can put them right where you need them most.

Most outdoor heaters run from propane cylinders that are not usually supplied with the heater and have to be purchased separately. They’re connected to your heater via a regulator and tube that is usually supplied, but you should always consult the manual that comes with your heater to ensure that you’re using the correct regulator and fuel supply for the heater.
