Recommended unit for Lebanon
Given New Hampshire’s cold northern climate and electric water heating, heat-pump (hybrid) is the sensible default for most Lebanon homes. Winter inlet water runs cold here, so recovery rate matters — size up a tankless or favor a high-recovery tank. A pro can confirm the right size and fuel for your home.

What affects water heater replacement cost in Lebanon?
Prices vary by unit type: tank gas ($750–$1,850), tank electric ($850–$2,000), tankless ($1,400–$3,200+), and heat pump ($1,650–$3,700). Labor and permit fees add $200–$500.
