Gas Water Heater Installation in Nampa
Gas water heaters remain the most popular choice in Nampa and the Treasure Valley, offering fast recovery times and lower operating costs than electric units in Idaho's natural gas market. Whether you're replacing a failed unit, upgrading to a higher-efficiency model, or making the switch to tankless, our licensed installers handle the complete job.
What's Included in Our Gas Water Heater Installations
- Old Unit Removal — We drain, disconnect, and haul away your old water heater. No disposal headaches.
- Gas Line Inspection & Connection — We inspect the existing gas flex connector for age and condition, replacing if needed. Tankless installations may require gas line upsizing.
- Proper Venting — Standard tank units use B-vent or direct-vent configurations. High-efficiency and condensing gas units require PVC venting. We ensure proper draft and code-compliant termination.
- Seismic Strapping — Required by Idaho code and the IRC. All units are strapped to wall studs per current standards.
- Permit Management — We pull the permit and schedule the required inspection with the City of Nampa or Canyon County.
- Testing & Commissioning — We light the pilot, set the thermostat to 120°F (safe household default), check for leaks at all connections, and confirm proper hot water delivery before we leave.

Yes. The City of Nampa and Canyon County require permits for water heater installations. Permit requirements include inspecting the gas connections, venting, and seismic strapping. All installations we perform include permit management and inspection scheduling.
Standard tank-for-tank gas water heater replacement takes 2–3 hours including draining the old unit, disconnecting gas and water lines, installing the new unit, and testing all connections. Tankless installations or gas line upgrades take longer—typically 4–8 hours.
For most Nampa single-family homes: 40-gallon for 1–3 people, 50-gallon for 3–4 people, 75-gallon for 4–6 people. For tankless, the right BTU rating depends on simultaneous demand and Nampa's cold groundwater temperature (approximately 55°F in winter). We'll size the unit correctly during your estimate.
