Buying Guide: What to Look For in an Electric Tank Water Heater
Capacity and Size
Before you buy, think about how much hot water you use daily. A small 8-gallon unit, like the ThermoMate Electric Tank Water Heater, is perfect for a single sink or a small RV. But if you need to supply a whole bathroom or kitchen, an 18-gallon model, such as the GE Appliances 18 Gallon Versatile Plug and Play, offers more reserve.
Also, consider the physical footprint. Compact units can be mounted under a sink or in a cabinet, while larger tanks need floor space. Measure your available area before committing to a purchase.
Heating Power and Recovery Rate
The wattage of the heating element determines how quickly the water heats up. Higher wattage means faster recovery, so you won’t run out of hot water as quickly. For instance, the VEVOR model features a 1600W element, while the ThermoMate offers 1440W. Both are adequate for light to moderate use.
If you have a larger household, look for a unit with a higher wattage to keep up with demand. For more insights on tankless options, see our best electric tankless hot water heater picks.
Installation Flexibility
Ease of installation can save you time and money. Many electric tank heaters are designed for simple plug-and-play setup, connecting to standard 120V outlets. The GE model, for example, installs in minutes with existing plumbing. Others may require hardwiring or professional help.
Also, check the water connection type. Most use standard 1/2-inch or 3/4-inch NPT fittings, which are common in most homes. If you’re comfortable with basic plumbing, you can likely handle the installation yourself.
Durability and Safety Features
A water heater is a long-term investment, so look for models with corrosion-resistant tanks and quality heating elements. The ThermoMate features a fused porcelain enamel glass lining and an Incoloy 800 stainless steel element, which resists corrosion and extends the unit’s life.
Safety is also critical. Check for UL certification and pressure relief valves to prevent accidents. For more on reliable brands, read our top electric tankless water heater brands guide.
Final Thoughts
Choosing the right electric tank water heater depends on your specific needs, whether it’s a compact unit for a tiny space or a larger tank for a small family. For a versatile and easy-to-install option, the GE Appliances 18 Gallon Versatile Plug and Play is a fantastic choice, while the ThermoMate Electric Tank Water Heater excels in durability and safety for point-of-use applications. Both offer reliable performance and convenience.
