How to Choose the Best 40 Gallon Electric Water Heater
Finding the perfect 40 gallon electric water heater for your home can seem like a daunting task. With so many models and features to consider, it's hard to know where to start.
An electric water heater can provide an efficient and low maintenance way to keep your household supplied with hot water. Choosing the right size and model for your home's requirements will ensure you get optimal performance.
Key Factors to Consider
When evaluating 40 gallon electric water heaters, here are the most important variables to examine:
- Capacity and household size
- Energy efficiency ratings
- Warranty coverage
- Installation requirements
- Budget
Capacity and Household Size
Consider how much hot water your household uses to determine the right tank capacity. 40 gallons is a common size for 3-5 people. For smaller households, a 30 gallon heater may suffice. Larger families may need a 50 gallon or higher capacity.
Take into account the number of bathrooms, showers, sinks, dishwashers, and washing machines using hot water. Will usage be staggered throughout the day or concentrated at peak times? This will impact the first hour rating and recovery rate you need.
Energy Efficiency Ratings
Electric water heaters carry an Energy Factor (EF) rating to compare efficiency between models. The higher the EF, the more efficient the heater. Look for options with an EF of 0.93 or greater.
You'll also see heaters marked with the Energy Star logo indicating they meet strict energy standards set by the EPA and DOE. Energy Star certified heaters have an EF of 0.95 or higher.
Warranty Coverage
Water heater tanks come with limited warranties typically ranging from 6-12 years. Models with longer warranties often cost more but may be worth the extra investment.
Also check what parts are covered beyond the tank, such as parts, labor, the anode rod, leaks, etc. Better warranties protect against corrosion and defects.
Installation Requirements
Before purchasing a unit, confirm you have adequate space with proper electrical connections and venting. Most 40 gallon electric heaters are around 61-67 inches tall. Make sure yours will fit in the installation location.
240V electrical service is usually required, involving a double pole circuit breaker. Your electrician can handle wiring the new circuit.
Budget
Higher efficiency, better warranties, and advanced features impact cost. Budget-friendly 40 gallon electric water heaters run $400-$600. Higher-end models cost $800-$1200+. Determine how much you can spend before shopping.

Compare Tank Construction and Insulation
Look for heaters with stainless steel or coated glass-lined tanks that resist corrosion. Foam or polyurethane insulation improves efficiency. Compare warranty terms on tank leaks.
Examine Energy Efficiency Ratings
Contrast the EF, First Hour Delivery , and estimated yearly operating costs. Remember higher EF numbers represent better efficiency and lower energy bills.
Check Warranty Terms
Make sure the warranty adequately covers parts and labor for the tank, leaks, and key components. Protection lasting 9-12 years is ideal.
Determine Right Capacity
Consider the Rated Storage Volume and Nominal Capacity . These indicate the realistic supply of hot water for your household's usage. Size appropriately.
Installation Needs
Confirm the heater dimensions fit the space, electrical service is sufficient, and venting needs are met.
Smart Controls and Settings
Look for user-friendly electronic controls and wi-fi app connectivity for managing settings and monitoring performance.
Installation Tips and Requirements
Proper installation is critical for energy efficiency, safety, and longevity. Here are key steps:
Electrical Requirements
240V electrical connections are needed, involving a 40 amp or 50 amp double pole circuit breaker in the main service panel. Hire an electrician if your home lacks 240V service.
Venting Needs
Most 40 gallon electric tank heaters require 4-inch PVC, CPVC, or stainless steel venting to the outdoors. Follow manufacturer instructions for venting specifications.
Plumbing Connections
Flexible water lines simplify connections to plumbing. Ensure inlet and outlet pipes are properly sized. Include shutoff valves.
Professional Installation Recommendations
While DIY installation is possible, it's best to have a licensed plumber or contractor handle the electrical and plumbing work. This ensures proper permitting, codes compliance, and safety.

Taking care of your new electric water heater helps optimize its performance and lifespan. Recommended maintenance includes:
- Flushing and draining tank annually to remove sediment
