Tankless water heater cost with installation — Manchester, NH
Last updated: September 24, 2026
What affects the price
Replacing your water heater involves several variables that change the final bill. The biggest factor is the unit type—tankless models usually cost more upfront than traditional tank-style heaters due to installation complexity. You also have to consider the fuel source, as switching from gas to electric often requires electrical panel upgrades. Size matters too; a larger home needs a unit with higher recovery rates. Finally, local building codes might require additional safety equipment, like expansion tanks or updated venting.
About this service
When you bundle the unit and the labor, the total investment fluctuates based on the model’s flow rate and the amount of pipe relocation required. Upgrading your venting system to meet safety codes for high-efficiency units is a primary factor in the final bill. We help you choose the right capacity for your household size.
