How old is your 82V80-2?

Letter-month + 2-digit-year decode in the serial number. See our Rheem age-by-serial-number page.

80G tanks are typically deployed in larger homes with predictable replacement cycles. Most 82V80-2 units in service are 12–20 years old at this point — past expected tank life. If yours is still running well, treat it as living on borrowed time.

Common parts

• Thermocouple — SP12090A, ~$25–$40
• Pilot assembly — SP12176C or SP15013, ~$60–$120
• Gas control valve — SP21176A (higher-BTU variant), ~$220–$320 (more expensive than 40G/50G valve)
• Anode rod — 48" or 54" hex-head aluminum-zinc, ~$50–$60
• T&P relief valve — 3/4" 150 psi 210°F, ~$25
• Drain valve — replace with brass at $25

When to replace

80G tanks at year 12+ are in the high-risk zone. The thermal cycling across 80 gallons creates more anode-rod consumption, more sediment accumulation, and more shell stress than 50G tanks. End-of-life indicators are the same as the 40G/50G but tend to appear earlier in the 80G's lifecycle.

If the tank itself is leaking — even a slow drip from the shell — replace immediately. 80G shell failures can flood basements in hours.

Modern Rheem equivalents

For atmospheric 80G replacement, Rheem's current lineup tops out at 75G — see Performance Platinum 75G or Performance 75G Atmospheric. Five gallons less capacity but modernized burner and EcoNet WiFi.

For larger capacity at higher efficiency, the RTGH-95DVLN tankless at 9.5 GPM continuous flow handles equivalent or higher peak demand than an 80G tank, with operating cost cut in half.

For all-electric high-capacity replacement, ProTerra 80G Heat Pump matches the 80G capacity at one-third the operating cost.

Bottom line

The Rheem Fury 82V80-2 is the legacy high-capacity Rheem residential gas tank. Most units in service today are at or past expected end of life. Use this page to plan replacement: modern equivalents are Performance Platinum 75G (tank), RTGH-95DVLN tankless (high-efficiency), or ProTerra 80G HP (electrification).
