Patio Heater


What is Patio?

Patio is an outdoor space for dining or recreation that adjoins a residence and is often paved.

What is Patio Heater?

A patio heater is an appliance for generating radiant heat for outdoor use. A burner on top of a post, burns liquefied petroleum gas (LPG), propane or butane or Natural gas and directs the flames against a perforated metal screen.

Almost all patio heaters are infrared. The sun is a great example of an infrared heater. Its rays travel through space and don’t heat it, but when it hits a solid object, Earth, heat is created. Infrared patio heaters don’t try to heat the air (like a convection heater) but instead heat the furniture, floor, objects, and people directly. That is in a covered area you will get some residual heat building in the air.

‘Heat Transfer through Radiation’ is the working principle of these devices. Every material, when heated to specific temperatures, emits heat in the form of electromagnetic waves in the infrared range.

Why Patio Heaters?

Patio is the best place to relax and to spend quality time with friends and family. But usually this pleasure is limited to certain seasons and times. This is because one cannot spend time in a patio when the weather is very cold. So, to enjoy every single second with loved ones and to relax every time in night, just need to get an outdoor patio heater.

Working Principle

A dome shaped patio heater is connected with a Natural Gas / Propane  Cylinder through a regulator mechanism. As soon as the heater is powered on and the regulator valve is opened, gas flows through the bottom inlet and into the burners placed at the top. The burners start operating, triggered by electric ignition, to heat up the radiant heating element placed above them. As the temperature of the element rises, it starts radiating heat in all directions. Since the dome is covered from the above and opens only on the sides, it is radiated horizontally and heat loss in the vertical direction is lesser.

This inventively designed mechanism ensures that most of the radiated heat is directed into a circular space around the heater. The heated element starts emitting infrared waves, which are absorbed directly by the human body, providing warmth. Through installation of multiple heaters, a large outdoor space can be kept warm quite easily. Thus, using a radiant heating element and a dome mechanism, these devices spread heat uniformly. They make for ideal installations to keep outdoor spaces warm in fall and winter.


Installation must be in accordance with local codes, or in the absence of local codes, with the latest edition of the National Fuel Gas code, NFPA 54/ANSI Z223.1 and National Electrical Code ANSI/NFPA 70, and for Canada, the latest edition of CAN/CGA – B 149.1 and Canadian Code, CSA C 22.1 part 1 and Part 2.

Each heater must be electrically grounded in accordance with the National Electrical Code ANSI/NFPA 70, when an external electrical source is utilized. In Canada, the CSA Canadian Electrical code C 22.1 part 1 applies.

Radiant Heat
The Commercial Outdoor Heater generates “Radiant Heat.” Unlike forced-air heat which goes up, radiant heat, like light waves reflect off of objects, warming the surface of the objects. This kind of heat is undisturbed by wind and ambient air temperatures.. Like light, radiant heat moves in waves. People absorb these waves creating a warming sensation on your skin and other surface objects. The more intense the BTU’s, the closer the radiant heat waves are, the more individuals will feel a warming sensation. The ambient temperature around the heater is equal to 50,000 BTU’s after burning for quite some time. The Commercial Outdoor Heater features an adjustable control valve, allowing for a desired heat output. Whether a cozy dinner on the patio or those large gathering, you’ll always have the right heat.

Burner Characteristics:

The Commercial Outdoor Heater burns with a blue flame being 2”-3” and a yellow/orange tip. The emitter will glow a red hot, radiating heat to the hood and down with warmth for you.


COMFORTING WARMTH from a single outdoor heater will cover 10” to 20 “ circle. It varies from person to person as some people require more warmth or less warmth than others to feel more comfortable and will either turn the heater up or down, or move closer or farther away as they desire.

Location of Patio Heaters

Our Outdoor Patio heaters by their fantastic infrared warm glow attract people. These patio heaters can be located in places where people can gather, sit or stand comfortably and where furnishings can be moved to accommodate the warmth.

Our Outdoor patio heaters can effectively operate to maintain a comfort level even in completely exposed areas. Weather protected area will be desirable for getting best warmth. Weather and wind protection allows the surrounding air to be warmed and used to enhance the direct radiant warming effects.

When adding heaters to existing construction, due consideration to be given to locating the heaters as near as possible to the gas supply line. Multiple heaters located on 8 to 10 “centers give overlapping heat patterns. This means more total heat reaches peoples in between units, and will provide comfort in weather even cooler than possible with a single heater.
