Key Facts About Fountain Hills and Tankless Water Heaters
Fountain Hills was designed by Robert McCulloch — the same developer behind Lake Havasu City — and built as a master-planned community from 1970 through 2000. The town centerpiece is the Fountain Hills Fountain, historically the tallest fountain in the world when dedicated. Original 1970s-1980s homes from the McCulloch era used construction methods similar to Lake Havasu City, including copper pipes now 40-50 years old and approaching comprehensive repiping decisions.
Fountain Hills sits 25+ miles from central Phoenix on the northeast fringe of the metro. The McDowell Mountain Regional Park and Fort McDowell Yavapai Nation border the community. This distance means longer response times for plumbing emergencies — a factor that makes choosing reliable, long-life equipment more financially consequential than in closer suburbs.
Eagle Mountain and FireRock Country Club represent the premium hillside luxury development in Fountain Hills. These properties have multi-level plumbing systems with significant elevation changes between fixtures — creating water pressure management challenges not found in flatland homes. A tankless unit on the ground floor of a three-story Eagle Mountain home must push water upward against gravity while maintaining the pressure required for proper operation.
