1. Rheem: Most Trusted Tank Brand
Rheem controls 32% of the U.S. tank market thanks to its ProTerra heat pump line (saves $470/year) and durable Performance Platinum series. Their 40-gallon models average 10 years lifespan with proper maintenance. Avoid their budget lines—glass-lined tanks corrode faster in hard water.
2. AO Smith: Best for Large Households
AO Smith’s Vertex gas heaters deliver 100 gallons in 40 minutes—ideal for families of 5+. Their patented Blue Diamond coating resists sediment buildup 3x longer than standard models. Pro tip: Flush annually to maintain warranty coverage.
Tankless vs. Tank: Which Lasts Longer?
Tankless heaters from Navien/Noritz average 20 years versus 8–12 for tanks. However, they require annual descaling ($150 service) and higher upfront costs. Tank models work better for:
- Homes with electric-only hookups
- Areas with water hardness over 10 GPG
- Budget under $1,500
Installation Costs by Type
- Standard tank (gas): $900–$2,200
- Hybrid heat pump: $1,800–$3,500
- Tankless (gas): $2,500–$4,500
- Solar-assisted: $3,000–$7,000
