Picture this: I came home after a long day, ready for a hot shower, only to be met with lukewarm water that turned icy in seconds. That was the final straw. I knew it was time to ditch my outdated water heater, and after a lot of research (and more cold showers than I’d care to admit), I landed on Rheem. With over 100 years in the game, Rheem’s reputation had me curious. Here’s what you need to know based on my experience and the stories of other DIY-ers who’ve gone through the same journey.
Why Choose Rheem?
Rheem has a wide range of water heaters, from traditional tank to tankless, and even hybrid options. The company’s known for its energy-efficient models, reliability, and durable designs. But, not every model is perfect for every household. I’ll help you navigate through which Rheem water heater might be your perfect match.
1. Rheem Water Heater Types: A Quick Overview
Rheem offers several types of water heaters to fit different needs, budgets, and home sizes. Let’s break them down.
A. Tank Water Heaters
Pros:
- Lower upfront cost
- Easy installation
- Familiar technology
Cons:
- Limited hot water supply (depending on the size of the tank)
- Larger footprint
- Higher energy usage over time
Top Pick: Rheem Performance Platinum 50-Gallon
This model hits the sweet spot for a typical household. It’s energy-efficient for a tank heater and comes with a 12-year warranty—one of the best in its class.
B. Tankless Water Heaters
Pros:
- Endless hot water supply
- Saves space (mounted on the wall)
- Lower energy bills due to on-demand heating
Cons:
- Higher upfront cost
- Requires professional installation
- Maintenance is more frequent (annual flushing recommended)
Top Pick: Rheem Performance 27 kW Tankless Electric Water Heater
I’ve heard nothing but good things about this unit. It’s compact, works with electric power, and provides enough hot water for two bathrooms running simultaneously. If you’ve got a mid-sized household, this is a good option to avoid ever running out of hot water again.
C. Hybrid (Heat Pump) Water Heaters
Pros:
- Super energy-efficient (up to 4x more efficient than standard electric models)
- Rebates and incentives may be available
- Can lower your energy bills significantly
Cons:
- Higher upfront cost
- Requires more space for installation
- Slower recovery rate compared to traditional heaters
Top Pick: Rheem Performance Platinum Hybrid 50-Gallon
This is one of the most energy-efficient units out there, with an impressive 3.55 UEF (Uniform Energy Factor). You can save hundreds on your electricity bill each year. It even has a Wi-Fi feature, so you can monitor and control it from your phone.
2. Energy Efficiency: How Rheem Helps You Save
Rheem is big on energy efficiency, which is a key reason I went with them. For anyone tired of massive energy bills, their models offer significant savings over time.
Tank Models
- Look for ENERGY STAR ratings, especially in their Performance Platinum line.
- A Rheem tank water heater can have an energy factor (EF) of up to 0.67, which is solid for traditional models.
Tankless Models
- With a tankless Rheem unit, you’re not paying to keep a whole tank of water hot all day.
- Some units boast 0.92 UEF, which is among the best for tankless systems.
Hybrid Models
- These are the energy champions of Rheem’s lineup. With UEF ratings of up to 3.55, you can expect long-term savings that justify the higher initial cost.
3. Durability and Build Quality
Rheem is known for the quality of materials and build durability. Whether it’s a stainless steel heat exchanger in their tankless models or the glass-lined tanks in their traditional units, these heaters are built to last.
Warranty Options
Most Rheem water heaters come with strong warranties:
- 6 years on basic models
- 12 years on premium models, like the Performance Platinum series
In my experience, knowing you’re covered for over a decade gives serious peace of mind.
4. Installation: Is It DIY-Friendly?
If you’re wondering whether you can install a Rheem water heater yourself, here’s the scoop:
- Tank Water Heaters:
If you’re replacing an existing tank model, installation is fairly straightforward. A solid DIY-er can handle this, assuming you’re familiar with basic plumbing and electrical work. - Tankless Water Heaters:
These are more complicated. You need proper venting, and possibly new gas or electric lines, depending on your home’s setup. I would suggest leaving this to the pros. - Hybrid Water Heaters:
These are tricky. Heat pump water heaters require adequate space and ventilation, so it’s best to consult a professional.
5. Common Issues & Maintenance
I’ve used a Rheem tankless system for over a year, and while the performance has been fantastic, there are a few things to be aware of:
Common Issues
- Sediment Build-Up:
Like any water heater, sediment build-up can occur, especially if you have hard water. Flushing the tank annually helps prevent this. - Tankless Cold Water Sandwich:
With tankless systems, you might experience a brief rush of cold water when switching between taps. While rare with Rheem, it can happen. - Noise:
I’ve heard some Rheem users complain of slight noise from hybrid models due to the heat pump fan, but this has been minimal in my experience.
Maintenance
- Tank Models:
Flush the system annually to remove sediment and check the anode rod every couple of years. - Tankless Models:
Clean the air intake filters and flush the heat exchanger annually. - Hybrid Models:
Aside from cleaning the air filter periodically, it’s relatively low-maintenance.

Final Verdict: Should You Go Rheem?
If you’re looking for reliability, energy savings, and a range of options to fit your household’s needs, Rheem is a solid choice. Personally, I’ve been impressed with the performance of my tankless Rheem heater—it’s delivered consistent hot water without any dips in temperature, and my energy bills have dropped. If you’re more traditional, their tank models offer a great balance between performance and cost. For those focused on long-term energy savings, the hybrid models are unbeatable.
