Water heater installation is the from-scratch side of hot water: setting a new system where the decision is about what you're adding — a new build or remodel, a bathroom addition that outgrows the old capacity, or a conversion from tank to tankless or heat-pump. It involves gas or high-amperage electric, pressurized water, combustion venting, and a tank holding 40–80 gallons over a finished floor, so the stakes are code and safety, not just comfort. As an authorized Rheem and Navien dealer we design and install tank, tankless, and heat-pump systems to current code across Arizona, with the safety hardware big-box installs routinely skip.
Every installation starts with sizing, because the unit you pick is a 10-to-20-year decision. We calculate peak simultaneous demand — bathroom count, tub size, laundry habits — and match fuel type and capacity to the home: a Bradford White or A.O. Smith atmospheric tank where simplicity wins, a Rheem or Navien tankless when the family wants endless hot water and wall-mounted space savings, or a heat-pump hybrid where electric operating costs justify the up-front price. The install itself is finished to code in Arizona: a new cold-water shut-off, a properly sized thermal expansion tank on any closed system, a code-length T&P relief discharge, seismic strapping where required, and correct combustion or power venting for gas models.
Upgrades and conversions are where installation earns its keep across Arizona. Moving to tankless means a larger gas line, new venting, and a condensate drain; adding a recirculation loop means a return line and pump; relocating a heater out of a closet means rerouting water, fuel, and venting — all permitted and inspected where Arizona requires it. We handle the full scope in one job, commission the system at temperature, and back the workmanship for 10 years.

Water Heater Replacement — if an existing heater has failed or is past its 10–15-year life and needs swapping out.
A new bathroom, laundry room, or accessory unit raises peak hot-water demand past what the existing system was sized for. The addition is the right moment to install capacity that matches the new Arizona floor plan.
The household has outgrown its capacity
More people, a soaking tub, back-to-back showers — demand grows past what the original unit was ever sized for. An upsized or tankless installation ends the hot-water rationing in the Arizona home.
You're switching fuel or going tankless
A tank-to-tankless conversion or an electric-to-gas switch is a new installation, not a swap: larger gas line, new venting, and a condensate drain, all sized and run to code across Arizona.
The current setup was never installed to code
No expansion tank, an unstrapped tank in a seismic zone, a T&P line that dead-ends — we find it constantly in Arizona. A corrective installation brings the whole setup to current code before it becomes a claim.
New construction or a first-time install
A new build, garage conversion, or ADU needs a heater spec'd from scratch — fuel, capacity, location, and venting chosen once and done right for the Arizona inspection.
What causes it — and what we fix
Undersized for real demand
The most common install mistake: a tank matched to the closet, not the household. We size to peak simultaneous use so the system keeps up from day one in Arizona.
Venting shortcuts
Wrong vent material, illegal slope, or a shared flue starves combustion and can push exhaust back into the home. We run the venting the manufacturer and Arizona code call for.
Missing expansion control
A closed system with a PRV or check valve spikes pressure every heating cycle when no expansion tank was fitted. We add a correctly sized one on every install that needs it.
Starved gas supply
Tankless and high-BTU tank units draw more gas than an old half-inch line can feed, causing ignition faults and lukewarm output. We upsize the line as part of the Arizona install, not as a callback.
Skipped permits and inspection
An unpermitted install surfaces at sale time or after a loss claim. We pull the permit where Arizona requires one and leave you the passed-inspection paperwork.

Asked & answered: water heater installation
Top questions homeowners searching for Water Heater Installation near me ask us:
Do I need a permit for a water heater installation?
Most jurisdictions require one — it covers the venting, T&P discharge, seismic strapping, and expansion tank that make the install safe. We pull it and meet the inspector where Arizona requires it.
How long does a water heater installation take?
A straightforward tank installation runs 2–4 hours; a tankless conversion runs 4–8 because of the gas-line, venting, and mounting work. New-construction and relocation installs are scoped ahead with a firm timeline for your Arizona project.
Will you install a unit I bought myself?
Yes — we confirm it's sized and vented right for the space first, flag it if it isn't, and install it to code with a new shut-off and expansion tank for your Arizona home.
Tank, tankless, or heat-pump — which should I install?
Tank wins on up-front cost and simplicity; tankless delivers endless hot water and a ~20-year life but needs a larger gas line and venting; a heat-pump hybrid costs the most up front and the least to run. We size and price the options for your Arizona home so you decide.
What brands do you install?
We're authorized Rheem and Navien dealers and also install Bradford White and A.O. Smith. Rheem and Navien lead for tankless, Bradford White and A.O. Smith for tanks, and Rheem or Bosch for heat-pump hybrids across Arizona.
