Where Lochinvar SQUIRE leads
- Longer SIT warranty (10-yr) vs PowerStor (6-yr)
- SSU lifetime warranty on stainless residential — strongest in the segment
- Pairs naturally with Lochinvar boilers for single-brand ecosystem
- Larger sizing available (SIT120)
- Wider contractor base not limited to plumber-only channel
Where Bradford White leads
- Premium tank construction — Vitraglas glass lining and heavy-gauge steel
- Aerostor 15-year warranty on stainless competitive with SSU lifetime
- Plumber-channel exclusivity — many plumbers strongly prefer Bradford White, easier to source through plumbing wholesale
- Reputation for tank longevity built over decades
Channel difference
Both are contractor-channel, but with different contractors:
- Lochinvar: plumbing-AND-heating contractors who do boilers
- Bradford White: general plumbers who do all water heating
If your installer is a plumbing-heating contractor specializing in boilers, they\'ll default to Lochinvar SQUIRE. If your installer is a general plumber, they\'ll default to Bradford White PowerStor/Aerostor.
