What's the Real Cost
THE REAL COST OF A TANKLESS UPGRADE
Homeowners in Phoenix, Scottsdale, and the surrounding Valley usually ask the same first question: what does a quality gas tankless water heater actually cost installed?
​
For a typical job that can use the existing gas line and replace the tank in the same location, here is what we see most often:
​
Gas Tankless: for a typical 2-bath home
150,000 BTU · 8.4 GPM · with built-in hot water recirculation
Average installed cost: $3,900–$5,000
​
Gas Tankless: for a typical 3-bath home
180,000 BTU · 10.1 GPM · with built-in hot water recirculation
Average installed cost: $4,500–$5,500
​
Gas Tankless: for a typical 4–5 bath home
199,900 BTU · 11.2 GPM · with built-in hot water recirculation
Average installed cost: $5,900–$6,000
​
Those ranges include the unit, standard installation in the same location as the old water heater, rerouting the piping, isolation valves, removal of the old heater, and our workmanship guarantee. These are averages prices not a bid.
​
When the gas line has to be upgraded
With today's condensing technology and in the Phoenix, and Scottsdale AZ area, it's rare to need to increase the existing gas line. Code or safety requirements sometimes call for a larger gas line, a longer vent, or an outdoor conversion. That added cost is real. We put it on the written quote before any work begins. That is how some jobs land above $7,000 - $12,000 range.
​
Quality is not optional
THE REAL COST OF A STANDARD TANK REPLACEMENT
Not every home needs a tankless upgrade. A quality tank-style water heater — gas or electric — is still the right choice when the budget is tighter, the existing hookups are already in place, or the household is happy with a traditional tank.
​
For a typical replacement in the same location, here is what Valley homeowners usually pay. These ranges include the new tank, the parts needed for a standard install, installation labor, and free haul-away of the old unit.
​
30-gallon gas or electric replacement
Best fit for a small home, condo, or light-use household.
Average installed cost for a 6-year factory warranty: $1,700–$2,000
​
Average installed cost for a 12-year factory warranty: $2,000–$2,200
​
40-gallon gas or electric replacement
The common size for many 1–2 bath homes.
Average installed cost for a 6-year factory warranty: $1,700–$2,000
​
Average installed cost for a 12-year factory warranty: $2,100–$2,300
​
50-gallon gas or electric replacement
The size most Phoenix and Scottsdale families replace.
​
Average installed cost for a 6-year factory warranty: $1,800–$2,100
​
Average installed cost for a 12-year factory warranty: $2,300–$2,700
​
75-gallon gas replacement
For larger homes that still want a tank. This size is gas only.
​
Average installed cost for a 6-year factory warranty: $3,400–$3,800
​
Average installed cost for a 12-year factory warranty: $3,700–$4,100
Those ranges include the water heater, standard installation parts, labor to set the new tank in the same location, and removal of the old unit at no extra charge. They also include our workmanship guarantee on the installation. These are average prices, not a bid.
​
What can move the price
The numbers above assume a straightforward swap: same fuel, same spot, existing vent or electrical already usable.
​
The written quote will be higher if the job needs a drain pan, expansion tank, new venting, a gas-line correction, an electrical upgrade, a stand or platform, a permit, or a move to a new location. We put those items on the quote before any work begins.
​
In Valley hard water, a standard tank is often due for replacement in 8–12 years. That is why some homeowners compare this one-time tank price with a Navien tankless that is built to outlast a second tank. Both options are legitimate. The right one depends on the house, the family, and the budget.

THE REAL COST OF AN ELECTRIC HEAT PUMP WATER HEATER
A heat pump water heater is the efficient choice for many all-electric Phoenix and Scottsdale homes. It still stores hot water in a tank, but it pulls heat from the surrounding air instead of running expensive electric elements all day.
​
We install the Navien NWP500 series in 50-, 65-, and 80-gallon sizes. For a typical replacement in the same location, here is what Valley homeowners usually pay. These ranges include the new heat pump tank, the parts needed for a standard install, installation labor, and free haul-away of the old unit.
​
50-gallon electric heat pump
Typical 2-bath home. 50-Gallon, Electric 220V heat Pump (Hybrid).
Average installed cost: $4,800–$5,300
65-gallon electric heat pump
Typical 3-bath home. 65-Gallon, Electric 220V heat Pump (Hybrid).
Average installed cost: $5,300–$5,700
​
80-gallon electric heat pump
Larger family or high-demand home. 80-Gallon, Electric 220V heat Pump (Hybrid).
​
Average installed cost: $5,800–$6,300
​
Those ranges include the water heater, standard installation parts, labor to set the new unit in the same location, and removal of the old unit at no extra charge. They also include our workmanship guarantee on the installation.
These are average prices, not a bid.
​
What can move the price
The numbers above assume the existing electric service can handle the unit and the tank is going in a space with enough air, clearance, and a place for condensate to drain — often a garage.
​
The written quote will be higher if the job needs a new 240-volt circuit, a panel upgrade, extra clearance or ducting, a drain pan, an expansion tank, a stand, a permit, or a move to a new location. In an Arizona garage, airflow and condensate routing have to be right or the unit will not run in its efficient heat-pump mode. We put those items on the quote before any work begins.
​
How this compares on the same page
A standard 50-gallon electric tank is the lower day-one price. A heat pump costs more to install and usually costs less to run — often several hundred dollars a year versus a conventional electric tank, depending on APS or SRP rates and household use.
​
The old federal 25C tax credit ended on December 31, 2025, so a 2026 installation does not qualify for that credit. Utility rebates still change by city and power company. We will tell you what is current for your address before you buy.
