40 Gallon Electric Water Heater Buying Guide
Buying the best 40 gallon electric water heater is easy if you know how to choose the right one. If you are unsure what to consider when choosing a water heater for your home, this buying guide is for you.
An electric water heater can put a considerable burden on your electric consumption if you do not choose wisely. Manufacturers typically add an Energy Guide label on their products.
As a general rule, you should get a product with a higher energy factor to reflect its water heating efficiency. Not only are these products more energy-efficient, they also have less impact on the environment.
First Hour Rating
In addition to an electric water heater’s energy efficiency rating, you may also want to check its First Hour rating. This parameter reflects the system’s ability to deliver hot water in the first hour of operation after fully heating the water.
For example, if the product has an FHR of 45 gallons, you can expect 45 gallons of continuous hot water for the first hour.
Water tanks store the heated water until you have a use for it. Unfortunately, heat also tends to move from a hotter area to a colder place. That is why it would be best to check the insulation of a water tank’s inner wall.
Some products come with a digital display to make operation and monitoring easy, even for beginners. The intuitive technology allows the system to adjust the water temperature and other operating parameters automatically, depending on your usage patterns and needs.
Some electric water heaters also have anti-scale devices in the tank. The technologies reduce limescale buildup, especially at the tank’s bottom.
Some high-end electric water heaters also come with a Wi-Fi module. This can help manage your water heating needs, even if you are not at home. Customization is more effortless this way.
A single 40 gallon electric water heater review is not enough to paint an accurate picture of a product. You need at least ten reviews to analyze the merits of the product. Pay special attention to negative comments as they can reveal a recurring issue in the water heater.
Always weigh the cons and the pros of the product. You can use your judgment in evaluating whether customer reviews are accurate or not. You can also try reading authoritative product reviews to make your decision-making a lot easier. Consumer reports water heaters reviews are a good place to start.
What brand of water heater is the most reliable? Reliability can partly be determined by warranty, as it shows a brand’s commitment to serving its customers.
Electric water heaters can come with a warranty of as short as three years and as long as 12 years. Most people will find products with extended warranties to be expensive. However, they do tend to have better insulation and the ability to heat water fast.
How Does It Work
Water heaters that use electricity are almost like gas-powered water heaters. They only differ in the source of heating. Whereas gas systems rely on propane or natural gas, electric water heaters connect to an electric outlet to heat an element inside the water tank.
An electric water heater consists of a tank, a heating element, and other components that work together to heat and contain the water until use.
The water enters the tank through a dip tube. Water fills the tank and gets heated by the heating elements. When someone opens a hot water faucet, hot water from the tank moves through the system’s heat-out pipe and the house’s water distribution line.
The system also features a T&P relief valve. One effect of increasing temperature is a commensurate increase in pressure. Because the water tank is a closed system, pressure can build up fast and cause the tank to break. The relief valve opens when the tank reaches a predetermined pressure level.
There is also a thermostat that maintains the ideal water temperature in the tank by monitoring temperature changes. If the water temperature is lower than the set parameter, the thermostat automatically adjusts the heating element’s power. Conversely, too hot, and the thermostat lowers the water temperature.
A drain valve at the tank’s bottom allows for more efficient tank maintenance. You can connect the valve to a hose to drain the water into a pool or a waterway.
The heating element is at the heart of the electric water heater. Without it, enjoying hot showers and warm kitchen sink water is impossible. The heating element draws its power from the house’s electric supply via an electric outlet.
Most homeowners have an issue with an electric water heater’s energy efficiency. Larger tanks tend to take more time to heat the water, translating to greater energy consumption. However, it is worth noting that many modern electric water heaters come with energy-efficient designs.
The water tank has several features that work to minimize energy dependency and optimize heating capability. The tank’s inner wall has an insulating layer that prevents heat from dissipating through the tank wall. There is also an anode rod that protects the tank’s inner wall against corrosion or even explosion.
A right water heater is not only energy-efficient. It also heats water fast to let your family enjoy warm showers, instant hot soups, and other hot water applications. It has excellent recovery times to give you a sufficient hot water supply without significant water temperature changes.
The best 40 gallon electric water heater is easy on the budget. Installing it is never an issue, and its durability and reliability are never questioned. While the operating costs are higher than gas-powered units, the right electric water heater can still provide you with exceptional savings for your family to enjoy. Buy one today!
