Buying a water heater involves five decisions. Make them in the right order and the choice gets easy. Here's the framework.
Shopping for a water heater can feel overwhelming—tank or tankless, gas or electric, what size, which brand, how efficient. Take the decisions in order and it gets simple. Here's the framework we walk customers through.
Decision 1: Tank or tankless
Start here. Tanks cost less upfront and handle big simultaneous draws; tankless costs more but delivers endless hot water, lower bills, and double the lifespan. (See our full tank vs tankless guide.)
Decision 2: Fuel type
Usually dictated by what your home already has. Gas is typically cheaper to run in NJ; electric is simpler; a hybrid heat-pump (electric) is the most efficient if you have the space.
Decision 3: Size
Match the unit to your household's peak demand, not just headcount. For tanks, that means the right gallon capacity and First Hour Rating; for tankless, the right flow rate for NJ's cold winters. Getting this wrong is the #1 regret.
Decision 4: Efficiency
Look at the energy rating. A more efficient unit costs more upfront but less to run. Energy Star and hybrid models may qualify for rebates that close the gap.
Decision 5: Brand
- Tanks: Bradford White (best build), Rheem (best value), A.O. Smith (heavy duty)
- Tankless: Navien (efficiency + recirculation), Rinnai (reliability)
The most expensive mistake isn't picking the 'wrong' brand—it's wrong sizing or a poor install. Get those right and any quality unit will serve you well.
Don't forget the install
Even the best unit fails early if installed poorly. NJ requires a permit and inspection for good reason. Choose a licensed installer who includes code upgrades, an expansion tank where needed, and proper venting.

Frequently Asked Questions
What's the most important factor when buying a water heater?
Correct sizing and a quality installation. A right-sized, well-installed mid-tier unit beats a premium unit that's wrongly sized or poorly installed.
Should I get tank or tankless?
Tankless if you'll stay long-term and value efficiency and endless hot water; tank if you want the lowest upfront cost or expect to move soon.
