The performance of any outdoor heater can be affected by environmental factors such as wind. However Bromic heaters have the highest wind resistance of any outdoor heaters on the market and perform well at wind speeds up to 13mph, making them by far the best-in-class. While built from premium materials and engineered for longevity, we do recommend that our Smart-Heat gas, electric and portable outdoor heaters are best mounted undercover and not directly exposed to salt mist, rain or snow .
