One of the most common questions Absecon homeowners ask. Both work fine — the right choice depends on your home and habits.
Upfront cost
Tank (40-50 gal): $1,400-$2,200 installed. Tankless: $3,500-$5,500 installed (gas line upgrades, larger vents, electrical work add cost).
Operating cost
Tankless uses 24-34% less energy. Annual savings: $80-$200.
Lifespan
Tank: 8-12 years. Tankless: 15-20 years.
Hot water capacity
Tank: Limited — 2 back-to-back showers, then recovery time. Tankless: Endless hot water but limited flow rate (can't always run shower + dishwasher together).
Space & reliability
Tankless mounts on a wall, saves floor space. Tanks are simpler with fewer failure points; tankless has computer boards that can throw error codes.
Our recommendation
Tank: 1-3 person household, budget-conscious, not staying 10+ years. Tankless: 4+ people, long-term home, want endless hot water.
