Woodbridge 7.5 GPM Condensing Gas Tankless Water Heater
Woodbridge 7.5 GPM Condensing Gas Tankless Water Heater Review
The Woodbridge 7.5 GPM Condensing Gas Tankless is a smaller-capacity variant of Woodbridge's 9.5 GPM tankless. Sized for 1-2 bathroom homes with sequential demand. Direct-to-consumer brand sold primarily through Amazon.
Specs: 160,000 BTU input, UEF 0.93 condensing, 7.5 GPM at a 35°F rise, stainless steel heat exchanger, PVC venting, WiFi connectivity. 12-year warranty on heat exchanger.
The Woodbridge positioning is value — about $900 unit versus $1,400-$1,800 for established competitors (Rinnai RL75iN, Navien NPE-180, Rheem RTGH-72) at the same capacity class. The trade-off is service network and brand history. Woodbridge is a relatively new entrant with parts and service handled through manufacturer customer service rather than dealer networks.
About $900 unit, $2,700 installed. The price advantage over major-brand equivalents is meaningful for the install scenario.
Right buyer: DIY-savvy homeowners or installations where the cost difference matters and the buyer is willing to manage service support independently. Wrong buyer: homeowners wanting traditional dealer-network service, anyone whose installer is unfamiliar with Woodbridge units. Most plumbers haven't worked on these — verify your installer's comfort with the brand before committing.
- Condensing modulation (UEF 0.96) — recovers exhaust heat; 15–30% lower gas bill vs non-condensing tankless
- UEF 0.96 — top-tier efficiency; qualifies for Inflation Reduction Act §25C residential credit
- 10-year warranty — solid above-average coverage for this class
- 7.5 GPM flow rate — sized for 2-bath simultaneous demand in warm-climate installs
- Requires dedicated 140K BTU gas supply line — undersized gas piping is the leading cause of flow-rate shortfalls
