Water Heater Installation in Boise & Treasure Valley
New tank water heater installation for Boise homes — 40 to 75 gallon capacity in gas and electric models. We remove your old unit, install the new one with all necessary connections, and handle permits and inspection. Same-day installation available for most standard replacements.
Boise's hard water shortens tank water heater lifespan to 8-10 years instead of the typical 12. Most Boise homes with 2-3 bathrooms need a 50-gallon tank minimum. We see a lot of premature failures from neglected anode rods — a $30 part that protects the entire tank from corrosion.

We assess your current setup, recommend the right size and fuel type, and schedule installation — often same-day for emergencies. We drain and disconnect the old unit, install the new one with proper connections, set the thermostat to 120°F, check for leaks, and handle the permit inspection. Old units are disposed of responsibly.
Water Heater Installation Cost in Boise
Typical water heater installation costs in the Boise area: $800-$2,500. We provide upfront pricing before starting any work.
Cost factors: Tank size (40 vs 50 vs 75 gallon), fuel type (gas vs electric), whether code upgrades are needed (expansion tank, earthquake straps, drain pan), and accessibility of the installation location.
Water Heater Installation Considerations for Boise Homes
Ada County building code requires a permit for water heater replacement. Expansion tanks are now required on most new installations. If your home is on a well (common in rural Kuna and Star), water pressure may affect tank performance and an expansion tank is critical.
Frequently Asked Questions
What size water heater do I need for my Boise home?
For 1-2 people, a 40-gallon tank is sufficient. For 3-4 people, go with 50 gallons. Families of 5+ should consider a 65-75 gallon tank or a tankless unit. Most Boise homes we install are 50-gallon gas units.
Is gas or electric better for a water heater in Boise?
Gas is more cost-effective to operate in Boise since Intermountain Gas rates are lower than Idaho Power electric rates for water heating. Gas units also recover faster — a 50-gallon gas tank delivers hot water about twice as fast as an equivalent electric model. However, electric is simpler to install if you don't have a gas line.
Do I need a permit to replace a water heater in Boise?
Yes. Ada County requires a plumbing permit for water heater replacement. We handle the permit application and schedule the inspection as part of every installation.
How long does water heater installation take?
A standard tank-for-tank replacement takes 2-3 hours. If code upgrades are needed (expansion tank, new gas line, venting changes), it may take 4-5 hours. Same-day installation is available for most emergency replacements.
