WHAT IS A TANK WATER HEATER?
Tank water heaters have two jobs: to heat water and to store it. These two tasks allow you to have hot water when you turn on the faucet or the shower. Virtually every house in America has a water heater – whether gas or electric – although knowing which one is best is often difficult.
Our guide is designed to showcase the best one the market across a variety of different categories, so you can make the smart decision for you and your family. For more information on tank water heaters, visit our What is a Tank Water Heater page and the Average Cost of a Tank Water Heater page.
METHODOLOGY
We compared a number of different water heater models to select our picks. We compared based on the following criteria:
- Reliability
- Price
- Storage
- Energy Efficiency
- 'Smartness'
Although we compared across all of these features, extra weight was given to that of reliability – after all, a smart heater that connects with all your devices is useless if it doesn’t effectively heat water. This, therefore, became our ultimate priority.
OUR OVERALL WINNER
The Rheem Performance Platinum Hybrid High Efficiency Smart Tank Electric Heater took our overall prize. It is a quiet, reliable piece of machinery with high-quality elements that reduce the chance of maintenance issues over time.
It is Energy Star rated with an impressive energy factor of 3.55, allowing you to recoup hundreds in energy costs each year. In addition, this water heater comes with smart features like built-in leak detection and “Vacation Mode” so you can easily stay head of any maintenance issues, maximize efficiency, and cut costs.
Topped off with a significant 10-year warranty, this is a water heater that allows you to sleep soundly at night knowing that it is constantly working to save you money and that you are protected for a long time.

If you want a water heater that will do its job reliably and efficiently, you can’t go wrong with this model. It’ll keep working day in and day out. This model is a real value option with premium performance.

What People are Saying:
“Water heats up as quickly as expected and unit is relatively quiet when burner is ignited. Excellent replacement water heater with a solid construction.”– Geno, SupplyHouse reviewer
“Easy install, requiring minor modification to existing pipes in order to make it fit. Replacement of the exiting water heater took about three hours for two of us – from emptying the old water heater to pressurizing and leak checking the new one. For a family of four we keep it at the low temperature setting and water is always enough” – TJ, Lowe’s reviewer

Westinghouse 60 Gal
If you have a large family – or simply hate running out of hot water – then this is the 60-gallon model for you. Although it comes in at an eye-watering $2,655, it will not only heat large amounts of water but will keep it warm for you.

A. O. Smith Voltex® Hybrid Electric

This one has an estimated 73% lower running cost than traditional tank heaters, meaning that you’ll start to really notice the difference in your energy bills. At around $1,300, this represents an investment that should pay dividends.

- Running Cost. The efficiency means less money spent on heating water - an estimated 73% less in most cases.
CONS
- Climate. If you live in a warm climate, this model may be overkill as it’s unlikely you’ll need to heat water to the extent that this model does.
- Price. There are cheaper heat pump models on the market that offer a comparable service.
- Noise. Some people complain of noise levels, saying it sounds like an old refrigerator running.
What People are Saying:
“At times I have 4 adults taking (long hot) showers, doing laundry, washing dishes, and have never run out of hot water, even in the efficiency mode. Runs less than $0.50 “per day.” When placed in your garage you hear nothing in your house, and your garage cools down. These types of units are most advantageous in year round hot climates. I am also in West Palm Beach, Florida. This brand and this unit is a ‘no brainer!’” – SupplyHouse reviewer
“I installed the 50-Gallon, Tall, 4500-Watt Hybrid about six weeks ago. I’ve only received one electric bill so far. It was about $20.00 less than the previous month but we have also started into the winter heating period so I would say the water heater is doing a great job.” – Lowe’s reviewer
With the rise of smart heaters, there’s a whole other set of questions when it comes to buying a water heater.
However, at its core, you need a model that will heat your water efficiently and reliably, and provide enough water for your home and family. Hence why the A. O. Smith model was our overall winner – nothing does the fundamental job of heating water better at a better price point. You may need some slightly different features, but if you want an unfussy, solid heater, you can’t go wrong with that model.
