Types of Water Heaters
Storage Tank Heaters
Traditional units like Rheem’s XR90 hold 40–80 gallons, with prices from $500–$1,800. They’re affordable but lose heat over time (“standby loss”). For lifespan tips, read AO Smith flushing frequency.
Tankless (On-Demand)
Navien’s NPE-A2 provides endless hot water at 11 GPM, but requires retrofitting for existing homes. Expect to pay $1,000–$4,500 installed.
Heat Pump Hybrids
Rheem’s ProTerra uses ambient heat, slashing costs. It works best in warm climates and costs $1,200–$3,000.
Installation and Maintenance Tips
Proper sizing is critical—oversized units waste energy, while undersized ones strain to meet demand. For gas models, ensure venting complies with local codes. Annual maintenance includes:
- Flushing sediment (tank models)
- Checking anode rods
- Inspecting for leaks
