My Journey Into The World of Water Heaters

When my old water heater started acting up—think lukewarm showers and a suspicious puddle in the basement—I knew it was time for a replacement.
I started researching, and RUUD and Rheem kept showing up as top contenders.
At first, I thought they were completely different brands, but I quickly learned they’re more like siblings under the same parent company, The Paloma Group.
This discovery made my decision both easier and harder.
Easier because they share similar tech and manufacturing standards, but harder because the differences are subtle and require some digging to understand.
I wanted a water heater that would last, save me money on energy bills, and fit my family’s needs without breaking the bank. I’m a practical guy, so I approached this like a puzzle, comparing features, costs, and long-term value.
Here’s what I found after weeks of research, talking to plumbers, and reading user reviews.
Understanding RUUD and Rheem: The Basics
Let’s start with the backstory. Rheem, founded in 1925, is a California-based heavyweight in the HVAC and water heating world. They’re known for their wide range of products, from traditional tank models to cutting-edge tankless and hybrid systems.
RUUD, established in 1897 by Edwin Ruud, was a pioneer in automatic water heaters. In 1959, Rheem acquired RUUD, and today, they operate as sister brands under The Paloma Group. Think of RUUD as the budget-conscious cousin and Rheem as the premium, tech-savvy one.
Both brands are manufactured in similar facilities, often in the U.S. or Mexico, and share core technologies like the EcoNet app for smart control and Rheemglas lining for corrosion resistance. But their marketing and product positioning differ.
RUUD targets affordability and reliability for residential use, while Rheem leans into innovation, offering premium features and commercial-grade options.
Key Features of RUUD Water Heaters
RUUD water heaters caught my eye because they’re often praised for being dependable without costing a fortune. Here’s what stands out:

- Affordable Pricing: RUUD models, like the Professional Achiever series, often cost $700-$800 for a 50-gallon tank, making them a go-to for budget shoppers.
- EverKleen System: This feature reduces sediment buildup, which means less maintenance and a longer tank life. My old heater had sediment issues, so this was a big plus.
- Guardian System: A safety feature that shuts off the heater if it detects flammable vapors, giving me peace of mind in my garage setup.
- EcoNet Compatibility: Some models let you control temperature and monitor energy use via the EcoNet app. It’s not as advanced as Rheem’s version, but it gets the job done.
- Variety of Models: RUUD offers gas, electric, tankless, and hybrid models, with tank sizes from 2.5 to 50 gallons. Their tabletop 40-gallon model is a neat option for small spaces like apartments.
- Warranty: Most RUUD heaters come with 6-10 years of coverage, with some models, like the Pacemaker, offering up to 12 years with a premium anode rod.
I liked that RUUD keeps things simple. Their heaters are built for the average homeowner who wants hot water without fuss. The copper pipes in RUUD models keep costs down, but I noticed they might not be as corrosion-resistant as Rheem’s aluminum pipes.
Pros And Cons of RUUD Water Heaters
Pros
- Cost-Effective: RUUD’s lower price point makes it easier to fit into a tight budget. A 50-gallon Professional Achiever model costs around $552-$800, compared to Rheem’s $799-$1,200 for similar specs.
- Reliable Performance: RUUD heaters are built to last, often running for 10-12 years with proper maintenance. The Guardian System and Rheemglas lining add to their durability.

Cons
- Higher Cost: Rheem’s premium features come with a premium price, often $200-$400 more than RUUD for comparable models.
- Mixed Reliability: Some users report issues with newer models, like faulty thermistors or gas valves, though Rheem’s support often resolves these quickly.
- Complex Installation: While straightforward, some Rheem models (especially hybrids) require professional installation to meet warranty terms, adding to costs.
- Noise Concerns: Hybrid models like the ProTerra can be noisy (around 58 dB), which might be an issue in a quiet home.
Where RUUD And Rheem Water Heaters Differ?
Now, let’s break down the key differences that shaped my decision. First, there’s the price. RUUD’s affordability is hard to beat. For a 50-gallon gas heater, I could spend around $700 on a RUUD Professional Achiever, while a Rheem Performance Platinum might set me back $1,000.
If budget is your main concern, RUUD is the clear winner.
But then there’s durability. Rheem’s aluminum pipes and non-metallic tanks (in models like the Marathon) are designed to outlast RUUD’s copper pipes. In my area, where hard water is a problem, corrosion resistance is a big deal.
Rheem’s materials gave me more confidence for long-term reliability, especially since I’ve dealt with rusty tanks before.
Energy efficiency is another battleground. Rheem’s hybrid models, like the ProTerra, achieve UEF ratings of 3.88-4.07, compared to RUUD’s 0.51-0.83 for most models. For a family like mine, with high hot water demand, Rheem’s efficiency could translate to $300-$500 in annual savings.
RUUD’s Ultra Series is efficient, but it doesn’t match Rheem’s top-end hybrids.
Smart features also tip the scales. Rheem’s EcoNet app offers advanced controls, like leak detection and integration with utility programs for rebates (one user mentioned earning $5/month). RUUD’s EcoNet is simpler, focusing on basic temperature control.
If you’re into smart home tech, Rheem feels more future-proof.
Installation and maintenance are fairly similar, but Rheem’s lightweight designs and included accessories (like NPT adapters) make DIY setups a bit easier. RUUD’s EverKleen system reduces maintenance, but Rheem’s non-metallic tanks require even less upkeep.
Both brands are widely available, though Rheem’s presence in big-box stores like Home Depot gives it a slight edge for convenience.
Ownership Experience: What Users Say
I dug into user reviews to get a real-world sense of ownership. RUUD owners often praise the brand’s reliability and value. One user on a plumbing forum said their RUUD Pacemaker lasted 12 years with minimal maintenance, thanks to the EverKleen system.
But others mentioned leaks after 8-10 years, especially in areas with hard water. This matched my concern about copper pipes.
Rheem’s reviews are a mixed bag. Many love the energy savings and smart features. A GreenBuildingAdvisor user raved about the ProTerra’s efficiency and Rheem’s responsive support when a thermistor failed. But some reported issues with newer models, like defective gas valves or noisy compressors.
A ConsumerAffairs review mentioned a Rheem tank failing just before the 9-year warranty expired, though Rheem replaced it promptly.
Plumbers I spoke to had opinions too. One swore by RUUD for its affordability and ease of repair, while another preferred Rheem for its durability and commercial-grade options. Interestingly, some plumbers warned against buying Rheem from big-box stores, claiming those models use cheaper components than those from professional suppliers.
Life Expectancy And Reliability

On average, RUUD water heaters last 10-12 years, with proper maintenance extending that to 15 years in some cases.
Their magnesium anode rods and Rheemglas lining help, but copper pipes can wear out faster in harsh water conditions.
Rheem heaters, especially the Marathon and ProTerra models, can hit 15 years or more, thanks to corrosion-resistant materials. However, some users report issues with newer Rheem models, like leak detection devices or thermistors, which can dent reliability.
In terms of reliability, both brands are solid but not flawless. RUUD’s simpler designs mean fewer parts to fail, but Rheem’s advanced tech can be a double-edged sword—great when it works, but frustrating if a component like a thermistor acts up. If you maintain your heater (flushing annually, checking the anode rod), either brand should serve you well.
My Decision-Making Process
Choosing between RUUD and Rheem came down to my priorities. I needed a 50-gallon gas heater for my family of five, with a focus on energy savings and durability. My budget was around $1,000, but I was willing to stretch for long-term value. Here’s how I weighed the options:
- Budget: RUUD’s lower price was tempting. I could get a Professional Achiever for $700 and stay under budget. Rheem’s Performance Platinum, at $1,000, pushed my limit but promised better efficiency.
- Efficiency: Rheem’s higher UEF ratings and hybrid options could save me $300-$500 a year, which adds up over a decade. RUUD’s efficiency was decent but not game-changing.
- Durability: Rheem’s aluminum pipes and non-metallic tanks felt like a safer bet for my hard water area. RUUD’s copper pipes made me nervous about corrosion.
- Features: I liked Rheem’s advanced EcoNet features, especially leak detection. RUUD’s simpler app was fine but less exciting.
- Warranty: Both offered 6-12 years, but Rheem’s reputation for responsive support edged out slightly.
After much back-and-forth, I leaned toward Rheem. The higher upfront cost stung, but the potential energy savings, durability, and smart features felt worth it. That said, if my budget was tighter, I’d have gone with RUUD without hesitation—it’s a solid choice for the price.
