Bradford White vs. Navien — McCorry's Preferred Brands

Bradford White (Tank)

Bradford White is McCorry's preferred tank water heater brand. Unlike brands sold at big-box stores, Bradford White units are sold exclusively through licensed contractors — meaning better quality control and parts availability. Known for durability and strong warranty support.

Navien (Tankless)

Navien's condensing tankless water heaters are among the most efficient available — 0.96 UEF rating. The NPE-S2 series is our go-to for Philadelphia rowhomes and homes with high hot water demand. Navien also offers a 15-year heat exchanger warranty, the longest in the industry.

What Affects the Price

Tank size: Standard 40-50 gallon is most common. Households of 4+ often need 50–75 gallon.
Fuel type: Gas units typically cost more than electric but are cheaper to operate in Pennsylvania.
Venting changes: Switching from tank to tankless often requires new direct-vent PVC — add $200–$800.
Gas line upgrade: Tankless heaters need higher BTU input — existing ½" lines sometimes need upsizing to ¾".
Expansion tank: Required in closed systems (most Philadelphia-area homes) — add $150–$300.
