Imagine living a life without one of the greatest luxuries: the miracle of modern invention, which runs throughout the home, hot running water. Does the hot water that you use to bathe, wash the dishes and clothing, the dog, sterilize the jars for pickling, the baby bottles, and relieve nasal congestion, and so much more, come directly from natural hot springs in the backyard? If so, then for one thing, you’re lucky, but chances are, your home relies on a water heater.
Over the last 60 years, trusty water heater tanks have been constructed in about the same fashion: a stainless steel or zinc plated copper sheath, a layer of glass insulation, the anode rod, a dozen or anti-corrosive parts and a temperature, pressure release, and electric heating element.
50-gallon water heaters are great for a family of 4-5 people, and the dog! It’s well equipped to deliver hot water to a 1-2 bathroom home, too small and meets the Goldilocks standard of being “just right.” 50-gallon electric water heaters heat enough water so the last person to take a shower isn’t standing in ice-cold water. And a 50-gallon electric water heater isn’t too big. Larger tanks tend to heat water, which is never utilized. This causes the water heater to function at a higher rate and produce a more expensive energy bill.
What is the best 50-gallon electric water heater to buy in 2021? The AO Smith ENS-50 ProMax Short Electric Water Heater. A.O. Smith knows how to build strong, durable, long-lasting water heaters.

Reviews of the 4 Best 50-Gallon Electric Water Heaters, Plus 1 to Avoid
1. AO Smith ENS-50 ProMax Short Electric Water Heater Review
A global leader in hot water tank production, A.O. Smith has been manufacturing quality water heater tanks for 80 years for millions of happy customers. The ProMax series is a part of the family of an innovative commercial-grade residential product line. A host of quality, tested parts make up the ENS-50 Promax. Boasting a 6 year limited tank and parts warranty, the tank alone features A.O. Smith’s unique CoreGuard technology. An outer layer of aluminium, extending the life of the water heater, protects the stainless steel core tank. Inside the aluminium shell, a Blue Diamond glass coating ensures superior performance and an extra layer of corrosion protection.
The most important part to consider when purchasing a water heater is the anode rod. The anode rod, sometimes referred to as the “sacrificial rod”, chooses how long the life of the water heater will function, and keeps the internal parts of the tank from corroding. Like the outer tank, the ENS-50 anode rod has a core of rust-fighting stainless steel. An easy-to-operate enhanced-flow brass drain valve makes for easy draining and maintenance of the tank.
The A.O. Smith ENS-50 comes with an impressive list of accolades. It meets all code compliances, is approved for manufactured housing, is CSA- and ASME- rated, and is certified and design-listed by the Underwriter’s Laboratory for 300 psi test pressure and 150 psi work pressure.

2021 Buyers Guide to the Best 50 Gallon Electric Water Heater
It’s natural to assume that the hot water flowing from the tap and through the pipes is always available, because that’s what the handle on the faucet with the red dot indicates. A little touch of science, some cutting edge technology, plus hundreds of years, and many experiments have occurred to deliver hot water to the tap. In other words, don’t take hot water for granted!
The journey of heating water for the home and its many uses spans centuries. The discovery of hot water delivery to pipes, sinks, showers and appliances has seen many incarnations; from wood fires, to Bunsen burners, storage-type gas powered heaters to today’s modern day tank systems. Most homes secretly conceal a hot water tank, bolted tight to a wall in an out-of-the-way closet, or tucked away in a basement.
The three most important things to remember when shopping around for an electric water heater include the safety features, the overall durability, including what is and isn’t included in a limited lifetime warranty, and the anode rod, and other anti-corrosive features to keep the electric water heater running efficiently for the lifetime of the home.
3 Main Points to Consider:
- Safety first: Plain and simple. An electric hot water heater needs as much TLC as the espresso machine. Regular low-cost maintenance should always include a regular clear passage for cold and hot flowing water, drain valves and temperature release valves, to clean the water heater and check for corrosion or blockage, and earthquake straps to prevent the heater from tipping or releasing from the wall if too much pressure builds in the tank. Read about ALL of the safety features and the materials used to build them. When in doubt, ask, and never attempt to clean or mount an electric water heater without education or hiring a professional.
- Durable construction: There is no need to feel the frustrations of electric water heater replacement and repair costs if the construction and durability of the water heater is solid and dependable. Look for glass-lined and fused insulation features, and solid brass release valves. These features significantly lengthen the life of the water heater. Well-insulated electric water heaters drive energy costs down, and parts made with quality metals won’t bend or break at the juncture points.
- Corrosion is the enemy: Most electric water heaters look the same on the outside, and solid construction is very important. But it’s the anode rod that should be one of the, if not the most important factor when choosing an electric water heater. Anode rods work to keep the inside of the tank and the parts that heat the water from corroding. Look for aluminium, magnesium and zinc anode rods. Expect the best anode rod, ask questions to the retailer or contact the manufacturer, so you can expect the very best lifetime performance from the electric water heaters.
How many gallons of water heater do I need?
For a family of 4-5, a 50-gallon electric water heater should do the trick. It’s important the first-hour flow and refill rates are consistent with the heating element, and that the scheduling of bathing and showers and running water-powered electronics are timed so that the hot-water flowing into the tank is sustained throughout the day.
Electric tankless water heater vs tank?
Upfront, the tankless water heaters can run hot water through the home indefinitely and on-demand. Tank water heaters need time to reheat the unused water and refill time to produce a full tank of hot water. The drawback is that tankless water heaters cost significantly more than electric tank water heaters. And so does the installation. In comparison, a tankless hot water heater with installation can cost between $1,500 and $2,000, whereas a tank system can run up to $600 installed and tank systems are much more DIY friendly. But make sure to read all the instructions and call an expert or the manufacturer when in doubt about any of the installation processes.
Gas vs propane vs electric water heater?
Propane water heaters cost about one-third less to run than electric water heaters, however, having a propane water heater comes with some risks. If the propane ruptures or leaks, it can cause the propane system to sink and leak gas into the ground. Any enclosed area proximal to a propane leak can be triggered by combustible explosion. A well-equipped propane water heater can save on average of $80 per year versus an electric water heater. Propane powered hot water heaters must pass inspections and come with higher maintenance and repair costs.
