If you’ve been browsing State Water Heaters, you’ve probably seen those labels sprinkled across product names. But what do they actually mean for your comfort, bills, and long-term peace of mind?

This guide breaks it all down—side-by-side. By the end, you’ll know:

• How each series is built and who it’s meant for

• What you get in efficiency, warranty, and recovery speed

• Which models qualify for rebates or ENERGY STAR® perks

• Which one truly fits your household

Let’s dive into the details that matter.

🧩 1. The Quick Lineup Overview

UEF = Uniform Energy Factor, the modern DOE metric for measuring water-heater efficiency—higher = more efficient .

⚙️ 2. State ProLine® — Tried, True, and Reliable

The State ProLine series is the brand’s foundation: dependable, affordable, and built to last.

Highlights

• Available in both gas and electric versions (30–80 gal).

• Glass-lined tanks resist corrosion and extend lifespan.

• Thick foam insulation minimizes standby heat loss.

• Standard 6-year warranty on tank and parts.

Real-World Fit

If you want straightforward hot-water reliability without the bells and whistles—and your household uses moderate daily water—this is your sweet spot.

Example: A family of four using a 50-gal gas ProLine with 40 k BTU input easily handles two morning showers and a dishwasher cycle.

Average UEF: 0.62–0.65 (gas), 0.92 (electric)
Installed cost range: ≈ $600 – $1,100

DOE field testing shows that upgrading even from a decade-old standard heater to a new 0.65 UEF ProLine can reduce annual energy use by about 10–15 percent .

⚡ 3. State ProLine XE® — High-Performance Efficiency

The ProLine XE line builds on the ProLine foundation with more efficiency, smarter technology, and extended warranty protection.

What You’ll Notice

• Higher-input burners or dual-element designs boost recovery speed.

• Energy Star® certified models available in both tank and tankless versions.

• Select gas models achieve 0.95 UEF via condensing technology.

• Optional Wi-Fi modules let you track usage or vacation-mode remotely.

• 8- or 10-year limited warranty, depending on model.

Ideal For

Households with heavier water demand or homeowners who care about long-term savings and connectivity.
Think of it as the “executive-class” version of the standard line.

Installed cost range: ≈ $1,000 – $1,800

According to the EPA’s ENERGY STAR Market & Industry Data 2023, certified condensing water heaters like ProLine XE models use about 25–35 percent less energy than baseline gas storage types .

🌿 4. State Hybrid (Heat Pump) — The Future of Water Heating

The Hybrid Electric Heat Pump series represents the State’s most advanced efficiency tech.
Instead of generating heat directly, it moves heat from surrounding air into the water tank—like a refrigerator in reverse.

Why It Shines

• UEF 2.75–3.70 + ENERGY STAR® Certified

• Can reduce energy use by up to 70 percent vs. standard electric models

• Multiple modes: Efficiency / Hybrid / Electric / Vacation

• Smart Anode Protection extends life and prevents corrosion

• 10-year warranty standard

Perfect For

Eco-conscious households, all-electric homes, or anyone chasing maximum rebate dollars.

Installed cost range (after rebates): ≈ $1,200 – $2,000

A 2023 NREL study on residential electrification found that heat-pump water heaters can save the average U.S. household $250–$350 per year while cutting emissions by 50 percent or more.
