Design and Build Quality
The first thing to notice about the Rheem tankless water heater is its sleek gray exterior. It may not win any beauty pageants, but it knows its purpose well. The unit’s compact design allows it to fit neatly in tight spaces—think closets, laundry rooms, or even the garage. It’s as if it understands the modest aesthetics of modern living.
Exterior Features
Upon closer inspection, the external digital thermostatic control with an LED display catches the eye. This feature not only looks modern but also boasts +/- 1 degree accuracy. It’s like having a hot water concierge right in your home, ensuring the perfect temperature for every whim. The interface is user-friendly, meaning even the most tech-challenged individuals can manage it without throwing a tantrum.
Internal Components
Inside the unit, the Rheem features durable copper immersion heating elements that are also field-serviceable. This means a skilled handyman can replace them without calling in an army of professionals. The self-modulating technology is another crowning achievement for the Rheem; it adjusts power to meet hot water demands seamlessly. For those who run multiple faucets simultaneously, this feature can be a game-changer.
Performance and Efficiency
Now, let’s get to the heart of the matter: performance. The Rheem 18 kW can deliver an impressive flow rate of up to 4.4 gallons per minute (GPM). This rate serves half the neighborhood’s hot water requirements with ease. Perfect for anyone who finds themselves taking romantic showers while wondering if the dishwater will drain cold.
Daily Usage
To further illustrate the tankless magic, consider this: running a dishwasher, washing machine, and taking a shower simultaneously is no longer a recipe for disaster. Each component works together harmoniously thanks to the Rheem’s ability to provide consistent and adequate hot water. No more spilling secrets about cold water mess-ups after a lovely long Sunday bath—those days belong to yesterday.
Flow Rate Breakdown
| Activity | Average GPM |
|---|---|
| Shower | 2.0 |
| Dishwasher | 1.5 |
| Washing Machine | 2.0 |
| Kitchen Faucet | 1.5 |
| Total | 7.0 |
In the above chart, it becomes evident that two or three of these activities can overlap. While the Rheem can achieve a staggering 4.4 GPM, knowing the needs of one’s household all together becomes crucial for maximizing its benefits. This heat hero does its job well, but understanding the flow is key!

Simple Installation
The installation process can be a daunting task for many homeowners. However, the Rheem has designed the unit to include bottom 3/4 inch NPT water connections, making it a breeze for those who dare. Threading the connections prevents unnecessary leaks and headaches during setup.
Installation Process
- Site Assessment: Ensure you have enough space and access to the water supply and electrical connections.
- Shut Off Water Supply: Before the installation, turn off the main water supply to avoid any flooding incidents.
- Position the Unit: Ideally, it should be placed near the main water supply.
- Connect Water Lines: Attach the bottom water connections.
- Connect Power Supply: Follow electrical guidelines or consult with a licensed electrician.
- Test the System: Turn on the water and power supply to make sure everything is functioning as expected.
For those who prefer to let a professional tackle the job, the unit’s simple design makes it easy for experienced installers to set it up quickly and efficiently.
Energy Efficiency
In an age when everyone seems to care about their energy bills more than their daily coffee fix, the Rheem shines brightly as an energy-efficient option. Utilizing a tankless system means heating water only when it’s needed, which can significantly reduce energy costs over time.
Cost Savings
In many reports, tankless units like the Rheem typically offer savings of anywhere from 25% to 50% on water heating costs compared to traditional storage tank models. Of course, the additional upfront cost might make some raise an eyebrow, but over the lifespan of the unit, these savings can make a considerable difference.
