Which one is right for you?
Choose Bradford White if…
- Your plumbing contractor is already in Bradford White's contractor-exclusive network and carries its tank, tankless, and combination parts.
- You need an oil-fired or electric water heater, fuel types Navien does not publish in its mainstream catalog.
- You want a standard tank replacement rather than a condensing tankless or combination system.
Choose Navien if…
- You want one unit to supply both domestic hot water and hydronic space heating.
- You have already ruled out Bradford White's tank-centric catalog and your contractor is a certified Navien installer for condensing tankless or combination units.
- For the specific models you were quoted, the published warranty terms favor Navien's heat exchanger coverage over Bradford White's tank warranty tier.
Choose neither if…
- Nobody has evaluated your gas line, venting, or electrical service for switching from a Bradford White tank to a Navien tankless or combination unit.
- Your current Bradford White tank is still under warranty and the issue traces to a thermostat, element, or anode rod rather than the tank shell.
- You have not yet gotten a written quote from a licensed local plumber or HVAC contractor for either brand.
The short answer
Bradford White sells tank, tankless, and combination products only through licensed contractors, with no published retail pricing. Navien's narrower published catalog centers on condensing tankless and combination boiler-water heater units, with a longer published heat exchanger warranty on some models. Neither company publishes installed pricing or independent reliability data.
Cost breakdown
| Line item | Bradford White | Navien |
|---|---|---|
| Condensing tankless unit, mid-capacity residential | Not published; contractor quote only | Not published by the manufacturer |
| Combination boiler-water heater unit | Not published in Bradford White's standard water heater lineup at the same scope | Not published by the manufacturer |
| Installation labor | Set by the contractor | Set by the contractor, often higher for combination units due to added hydronic piping |
| Permits | Set by your jurisdiction | Set by your jurisdiction |
Neither brand publishes equipment or installed pricing. Combination units that also serve space heating typically involve more piping and controls work than a standalone water heater, which a licensed contractor should itemize separately.
Decision framework
Bradford White publishes tank, tankless, and combination products; Navien's mainstream catalog is tankless and combination units only.
Navien publishes combination boiler-water heater models; Bradford White does not publish a comparable combination product.
Bradford White publishes oil-fired models; Navien's published lineup does not include oil-fired units.
Bradford White's contractor-exclusive policy and Navien's reliance on certified installers both mean parts and warranty service hinge on the installer's supplier relationship.
- Assuming Bradford White's tank or combination units are listed anywhere online; its contractor-exclusive distribution policy means pricing is set only at the contractor level.
- Assuming Navien sells a mainstream electric or oil-fired water heater; its published US lineup centers on gas tankless and combination units.
- Comparing a Navien combi unit's installed cost against a standalone Bradford White tank without separating out the hydronic piping work.
- Assuming every Navien model sold against Bradford White carries the same heat exchanger warranty term; published terms vary by model line.
- Not confirming that a licensed plumber or HVAC contractor, not a handyman, handles gas line, venting, or hydronic piping work on a Bradford White to Navien switch.

Frequently asked questions
Can I buy a Bradford White water heater without a contractor?
No. Bradford White publishes a contractor-exclusive distribution policy and does not list its products at retail. Navien's condensing tankless and combination units are also typically sold and specified through contractors.
Does Bradford White make combination units like Navien?
Bradford White publishes combination water heating products, but Navien's published combination boiler-water heater line has a track record specific to condensing tankless technology serving both domestic hot water and space heating.
Which brand has the longer tankless heat exchanger warranty?
Navien publishes a 15-year heat exchanger warranty on some residential condensing tankless models. Bradford White's published tankless warranty terms vary by model tier. Confirm the exact tier for the model quoted.
Is one brand more reliable than the other?
We found no independent public dataset ranking Bradford White against Navien for reliability or repair frequency, so we do not publish a ranking.
Why doesn't Bradford White show prices online?
Bradford White's stated distribution model sells only through licensed contractors and wholesalers, not retail or e-commerce, so pricing is set at the contractor level rather than published for comparison against Navien.
Is gas line, venting, or hydronic piping work involved in either installation safe to do myself?
No, whether you go with Bradford White's tank line or Navien's tankless or combi unit. Gas line, venting, and combustion-related work should be evaluated and performed by a licensed plumbing or HVAC contractor in accordance with local plumbing and mechanical codes. Do not attempt gas line, flue, or venting modifications yourself.
