Three large panels measuring 83.8 x 38.1 cm form a heat focusing reflector designed for round natural gas and propane patio heaters. An improved mounting method keeps the reflector securely attached to the heater even after long use. Energy efficient design: An adjustable heat spread area expands the heating zone and prevents heat from being wasted on walls, trees, or other non target surfaces. This helps focus warmth where it is needed and may extend propane usage. Increased safety: The thermal focusing reflector directs heat away from surrounding objects, reducing the risk of accidents. The shielding acts as a protective barrier, guiding heat to the required areas and minimizing damage or incidents. Stable and durable: Made of metal that is break and rust resistant for long term durability. The weight is appropriate to prevent bending or instability of the heater. Use scenarios: - Outdoor dining or lounge areas near walls or landscaping where heat loss is a concern, concentrating warmth toward guests. - Open patios with round gas heaters, directing heat toward seating for efficient comfort and energy savings. - Windy or cluttered spaces where shielding helps keep heat focused and away from obstructions.
