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 Your Installation Cost
In Lebanon, the main cost drivers are unit type (tank vs. tankless), new gas line installation ($275–$950), and permit fees.
