How many SUNPAK units do I need?

Coverage is relative to climate. Our experience has been that in warm climates (Southern California, Arizona, Florida, Texas) an S34 mounted between 8-9 feet, will cover a 12’x12′ area and the S25 a 10’x 10′ area. In cooler climates such as (Colorado, Utah, Idaho, Washington, Michigan) the coverages are more like 10’x 10′ for an S34 and 8’x 8′ for the S25. Wind is a big factor in any outdoor heating project. A continual breeze (20+ mph) will make heating any patio very difficult. We encourage patio owners to use natural windbreaks were possible.
