Reliance Water Heaters: full buyer's guide
Reliance is AO Smith\'s hardware-store-channel budget brand — the badge AO Smith uses when it ships to Ace Hardware, True Value, Do it Best, plumbing wholesale distributors, and select non-Lowe\'s big-box outlets. Same manufacturing as State, Whirlpool, and AO Smith Signature; different distribution channel and different badge. If you\'re shopping for a water heater at your local Ace, True Value, or independent plumbing supply, you\'re almost certainly looking at Reliance.
The Reliance water heater lineup
Six product families cover the catalog, organized around AO Smith\'s warranty-tier naming convention. Model numbers begin with the warranty tier (6-, 9-, or 12-), then capacity, then platform code (NORT = natural gas, EORS = electric, PVRT = power vent, SOMS = small/point-of-use):
- Standard 6-Year Gas (6-NORT series) — entry-tier atmospheric gas tanks. 30-gal (6-30-NORT), 40-gal (6-40-NORT), 50-gal (6-50-NORT), 75-gal (6-75-NORT). 6-year tank warranty.
- Standard 6-Year Electric (6-EORS series) — entry-tier electric tanks. 30-gal, 40-gal, 50-gal, 66-gal, 80-gal.
- 9-Year Extended Warranty (9- series) — mid-tier with improved insulation and heavier anode rod. 9-40-NORT gas, 9-50-NORT gas (volume), 9-50-EORS electric. Equivalent of AO Smith Signature Select tier.
- 12-Year Premium (12- series) — top tier. 12-50-NORT 50-gallon gas with 0.65 UEF and heaviest anode rod. Equivalent of AO Smith Signature Premier.
- Power Vent (PVRT series) — fan-assisted PVC sidewall venting for chimneyless installs. 40-gal PVRT, 50-gal PVRT. 120V required.
- Point-of-Use Mini-Tank (SOMS series) — under-sink and supplemental electric tanks. 6-gallon, 10-gallon. 120V plug-in — no electrical work required.
- Hybrid Heat Pump (HPHE series) — AO Smith Voltex platform at hardware-channel pricing. 50-gal HPHE-50, 66-gal HPHE-66. 3.45 UEF, Energy Star, IRA $2,000 federal tax credit eligible. 10-year tank warranty.
Reliance, State, AO Smith Signature, Whirlpool — the family tree
AO Smith operates four brand badges in US retail and wholesale water heater distribution, all manufactured in the same AO Smith facilities (McBee SC, Ashland City TN, Juarez Mexico, Fergus Ontario) with the same engineering team and components. The differences are channel, warranty tier within channel, and badge.
| Brand | Primary channel | Positioning |
|---|---|---|
| AO Smith (Signature Select / Signature Premier) | Lowe\'s retail + plumbing wholesale | Mid (9-yr) and premium (12-yr) tiers at Lowe\'s and contractor channel |
| State (ProLine) | Lowe\'s retail + plumbing wholesale | Value tier at Lowe\'s; contractor-channel volume brand |
| Whirlpool | Lowe\'s retail (licensed brand) | Value tier at Lowe\'s leveraging Whirlpool appliance brand recognition |
| Reliance | Ace Hardware, True Value, Do it Best, plumbing wholesale | Hardware-store-channel value brand; non-big-box distribution |
The strategic intent: AO Smith Signature and State cover Lowe\'s. Whirlpool covers the brand-recognition cross-shop at Lowe\'s. Reliance covers everything that isn\'t Lowe\'s — Ace Hardware\'s ~5,000 US stores, True Value\'s ~4,500 stores, Do it Best\'s ~4,000 stores, and the contractor-direct plumbing wholesale channel that doesn\'t run through Ferguson (which carries State for AO Smith). If you have a Menards in your area you\'d see Richmond (Rheem subsidiary); if you have an Ace or True Value, you\'d see Reliance (AO Smith subsidiary).
Why Reliance dominates the hardware-store channel
Hardware stores have a different shopper than Lowe\'s or Home Depot. Ace, True Value, and Do it Best are independently-owned cooperatives concentrated in smaller towns and suburbs without nearby big-boxes. The shopper is typically a long-time local customer with a plumbing emergency who wants a tank water heater today, not a delivery in three days. The store needs a brand that supplies in tank-emergency volume.
Reliance supplies that channel exclusively for AO Smith. The pricing is competitive — sometimes Reliance at a local Ace prices below the equivalent State at Lowe\'s due to hardware-cooperative buying power on emergency-replacement SKUs. The 40-gal and 50-gal 6-year tier in particular is positioned as the local-hardware-store emergency tank-swap replacement.
Tier-to-tier mapping
| Warranty tier | Reliance | State | AO Smith | Whirlpool |
|---|---|---|---|---|
| 6-year tank | Standard (6-NORT / 6-EORS) | ProLine | — | Standard NU/EU |
| 9-year tank | Extended Warranty (9-) | ProLine Master | Signature Select | Energy Smart |
| 12-year tank | Premium (12-) | ProLine XE | Signature Premier | — |
| 10-year heat pump | Hybrid (HPHE) | Premier Hybrid | Voltex Hybrid | Hybrid Heat Pump |
| Power vent (6-yr) | PVRT | ProLine Power Vent | — | Power Vent |
| Point-of-use mini-tank | SOMS | — | — | — |
Same product across the four brands at equivalent tiers. The choice is which retailer + channel you prefer.
Which Reliance is right?
- Gas, electric, or heat pump? Gas for fast recovery and lowest operating cost where natural gas is plumbed. Electric for simpler install. Hybrid heat pump for dramatic energy savings and IRA $2,000 federal tax credit
- If gas: which warranty tier? 6-NORT for emergency same-day swap or budget priority. 9-NORT for mid-tier value. 12-50-NORT Premium for long-term ownership
- Atmospheric or Power Vent? Atmospheric (6-NORT / 9-NORT / 12-NORT) for chimney installs. Power Vent (6-PVRT) for chimneyless installs needing PVC sidewall venting
- Electric capacity: 30-gal for 1-2 person, 40-gal for 2-3, 50-gal for 3-4, 66-gal for 4-5, 80-gal for 4-5+ when gas isn\'t available and heat pump install space isn\'t feasible
- Need a small tank for a remote sink? 6-6-SOMS (6-gal) or 6-10-SOMS (10-gal) plug into a standard 120V outlet — no electrical work, mounts under-sink or in a closet
Hybrid Heat Pump — Reliance\'s value play
The HPHE line is Reliance\'s value play in heat pumps. Same AO Smith Voltex platform — 3.45 UEF, 10-year tank warranty, Energy Star certified, IRA $2,000 federal tax credit eligible — at Reliance pricing that often beats equivalent State Premier Hybrid or AO Smith Voltex by $100-200 at the same nominal capacity.
Availability is the catch: HPHE-50 and HPHE-66 are stocked at a fraction of Reliance dealers. Larger Ace and True Value stores in heat-pump-incentive markets (CA, MA, NY, OR, VT, WA) carry them; smaller hardware stores often don\'t. Call ahead. In IRA + state/utility rebate-stacking markets, the HPHE-66 at $1,599-1,999 minus rebates can net the install around $500-1,000. See our rebates and tax credits guide.
Point-of-Use mini-tank — the Reliance specialty
Reliance is one of the few major brands that still carries a residential point-of-use mini-tank line at hardware-store distribution. The SOMS-100 series (6-gallon and 10-gallon) plugs into a standard 120V outlet and installs under-sink or in a closet — no electrical work, no permit in most jurisdictions. Common use cases:
- Distant kitchen sink — main water heater takes too long to deliver hot water
- Wet bar / coffee station — supplemental hot water for one fixture
- Garage utility sink — no need to extend hot water lines
- Bathroom remodel — booster behind a recirculation pump for instant hot water
- RV / tiny home / ADU — primary water heater for a single bathroom
The 6-gallon at $199-279 and 10-gallon at $249-349 are competitively priced vs Bosch Tronic mini-tanks and Bradford White SUVT residential point-of-use.
Error codes — same as AO Smith family
Reliance shares the AO Smith family LED flash code system on gas tanks. The status LED is on the gas valve. Flash codes translate directly across the family — same codes mean the same things on State, AO Smith Signature, Whirlpool, and Reliance.
| LED flash code | Meaning |
|---|---|
| 1 flash | Normal operation |
| 2 flashes | Thermopile low voltage |
| 3 flashes | Excess temperature (ECO trip) |
| 4 flashes | Faulty temperature sensor |
| 5 flashes | Vent obstruction or back-drafting |
| 6 flashes | Flammable vapor sensor lockout |
| 7 flashes | Gas control valve failure |
| 8 flashes | System or wiring fault |
See the Reliance error codes hub for troubleshooting steps. Electric tanks use ECO (Emergency Cutoff Off) red-button reset on the upper thermostat — same as State and AO Smith.
Reliance warranty
| Product tier | Tank / Heat Exchanger | Parts | Labor |
|---|---|---|---|
| Standard 6-Year Gas / Electric | 6 years | 6 years | 1 year |
| 9-Year Extended Warranty | 9 years | 9 years | 1 year |
| 12-Year Premium | 12 years | 12 years | 1 year |
| Power Vent | 6 years | 6 years | 1 year |
| Point-of-Use Mini-Tank | 6 years | 6 years | 1 year |
| Hybrid Heat Pump | 10 years | 10 years | 1 year |
| Commercial application | 3 years | 3 years | 1 year |
Tier-for-tier identical to State, AO Smith Signature, and Whirlpool equivalents. See the Reliance warranty hub.
How old is my Reliance?
Reliance serial numbers use the same encoding as the AO Smith family (same factories). First two characters encode year and week. See our Reliance age lookup guide for full decoding by serial format.
Parts directory
Reliance parts interchange with State, AO Smith Signature, and Whirlpool parts on equivalent products (same factories, same engineering). Available through Reliance dealer counter, AO Smith distribution, and Amazon:
- Anode rod — replace every 4-7 years; aggressive water 3-4 years
- Heating element — electric tanks; upper/lower 4500W standard
- Thermostat — electric upper/lower
- Gas valve — gas units; dealer-only replacement for warranty
- Thermocouple — older standing-pilot Reliance tanks
- Dip tube — broken = hot water runs out fast despite good thermostat
- Drain valve — replace plastic valve with brass ball valve after first flush
Install requirements
Reliance install requirements are identical to the AO Smith family for equivalent product types. See the Reliance install guide. Key points:
- Atmospheric gas (6-NORT / 9-NORT / 12-NORT): existing B-vent chimney with adequate draft
- Power Vent (6-PVRT): 120V outlet + PVC sidewall venting (10-40 ft typical run)
- Electric (6-EORS / 9-EORS): 240V dedicated 30A circuit
- Point-of-Use (6-6/10-SOMS): standard 120V outlet, under-sink or closet
- Hybrid Heat Pump (HPHE): 240V + 700+ cubic feet unconditioned air space + condensate drain (gravity or pump)
Maintenance
Standard tank water heater maintenance. Annual tank flush, anode rod inspection at 4-7 years, element resistance test if recovery slows. See Reliance maintenance hub.
Reliance vs competitors
- Reliance vs AO Smith — same manufacturer, hardware-channel vs Lowe\'s/wholesale
- Reliance vs State — same manufacturer, hardware-channel vs Lowe\'s
- Reliance vs Whirlpool — same manufacturer, hardware-channel vs Lowe\'s
- Reliance vs Rheem — AO Smith hardware-channel vs Rheem Home Depot
- Reliance vs Richmond — AO Smith hardware-channel vs Rheem Menards-channel
- Reliance vs Bradford White — budget hardware vs premium plumber-only
Where to buy
Reliance sells primarily through:
- Ace Hardware (~5,000 US stores) — emergency tank-swap volume
- True Value (~4,500 US stores) — same role as Ace
- Do it Best (~4,000 US stores) — primarily Midwest hardware cooperative
- Plumbing wholesale — independent wholesale distributors outside the Ferguson/State channel
- Amazon — limited but growing Reliance listings, mostly the SOMS mini-tank line
Not at Lowe\'s (State / Whirlpool / AO Smith Signature there) or Home Depot (Rheem there). See Reliance dealers hub.
Customer service
Reliance customer service: 1-800-365-4054. Hours: Monday-Friday, 7 AM - 7 PM Central. Same AO Smith corporate support team that handles State, AO Smith Signature, and Whirlpool inquiries. Hold times typically 10-20 minutes; longer Mondays. Have your serial number ready — first two characters encode manufacture week and year.
Owner reviews
Reliance reviews skew positive on emergency-swap value through Ace and True Value. Reliability matches State and AO Smith Signature equivalents (same manufacturing). Mini-tank SOMS owners are the most enthusiastic — the under-sink 6-gal and 10-gal models punch above their price for distant-fixture and supplemental applications. The 6-year warranty on Standard Gas draws the most complaints — homeowners who want longer warranty should step up to 9-Year Extended or 12-Year Premium. See Reliance owner reviews.
Bottom line
If you shop at Ace Hardware, True Value, or Do it Best, Reliance is the obvious AO Smith-manufactured choice. 6-NORT for budget tier and emergency same-day swap. 9-NORT for mid-tier value. 12-50-NORT Premium for long-term ownership. HPHE-50 / HPHE-66 for the heat pump IRA-credit-stacked play where dealers stock them. SOMS mini-tanks for distant-fixture point-of-use. For Lowe\'s shoppers, the equivalent tiers carry State or AO Smith Signature badges; for contractor wholesale, AO Smith Signature; for hardware-store and emergency-swap retail, Reliance is the badge — same product, different channel.
