⚖️ Side-by-Side Comparison
Tank vs Tankless Water Heater
Tank water heaters install for $600-$1,800; tankless runs $1,800-$4,500 installed. Tanks win on upfront cost and simpler retrofit; tankless wins on lifespan (20+ years vs 10-15), energy savings (8-34%), and endless hot water. Tankless pays back in 5-10 years depending on usage; needs a 3/4-inch gas line and venting upgrade in many homes.
