UNDERSTANDING THE CHALLENGES

Since an outdoor area is not a confined space by walls and roof structure, forced air systems are not effective in controlling the ambient temperature. In an outdoor environment, hot air rises and quickly dissipates. Even the slightest breeze will diminish the effect of heating system, making a forced air heating system impossible.

THE SOLUTION

The only way to heat an outdoor area is through radiant heat. Radiant heat warms objects, not the air, similar to the experience of the sun warming your skin.Because radiant heat focuses on objects and not air, radiant heaters are wind resistant and can still warm people even in mild wind conditions. This method involves projecting infrared heat radiation onto people rather than moving warm air into the outdoor patio. Radiant heating is the foundation for all Bromic heaters. When properly specified, Bromic can heat any outdoor space more effectively than many of our competitors because of this principle.

DEFINE YOUR OUTDOOR SPACE

Outdoor areas are defined as being least 30% open (front, back or side walls). If a patio is partially covered, then it can capture heat inside the structure, also known as a heat cloud, creating a convectional heating effect.Understanding the structure in design and engineering helps dictate the type and amount of heating required.Considerations to be aware of:

• Seasonal changes in your geography
• Proximity to water
• Proximity to air flow or wind direction
• New or existing construction
• Building Codes
• Clearances
• Energy sources

UNDERSTANDING THE TYPES OF HEAT

Manipulating direction of heat is a critical factor in designing your outdoor heating solution. The most effective heaters use directional heating elements for efficient energy usage and to avoid over-heating guests.

Outdoor heaters utilize one of two different methods to transfer thermal energy:

1.) CONVENTIONAL HEAT emits hot air that mixes with ambient air to raise the average temperature of an area.

2.) INFRARED HEAT heats target objects themselves as they come into contact with waves of infrared light. Note: Infrared radiant heat is considered the most effective and energy efficient heat source for alfresco areas. This factors into green energy and sustainable design considerations.
