Key Takeaways

• Electric water heaters are generally more efficient, using less energy and offering on-demand hot water, leading to savings.
• Electric water heaters work with heating elements, and only one element operates at a time to heat water.
• Different types of water heaters are available, including tankless, storage tank, heat pump, condensing, and solar water heaters, each with its own benefits and considerations.

What Is a Water Heater?

In general, a water heater is a steel tank that has an electric heating coil at its lowest position that usually heats the water within immediately you plug into electric power. Typically, a thermostat regulates the water’s maximum temperature. Freshwater gets into the tank from outside, and eventually, hot water comes out of the tank whenever you turn on your sink hot water tap. Due to the cold water’s pressure, hot water comes out of the tank and through the hot water tap.

How Does an Electric Water Heater Work?

Typically, electric water heaters comprise two heating elements (although compact models might have only one). They’re just similar in operation and appearance to the heating elements that you find in an electric stove. Typically, they heat from inside the tank, however, while submerged in water. Close to the top of the tank, you’ll find one heating element while the other is close to the bottom. Every single element has its thermostat which you can adjust separately. At any time, only a single element is in operation.

Only the bottom element is on during the times of little or no hot water use. As required, you’ll introduce cold water close to the bottom of the tank, and then it’s heated by the bottom element. Through convection, the water rises to the tank’s top whenever it’s heated. The upper element won’t turn on since it’s surrounded by hot water. Once you open a hot water faucet, hot water will come out of the tank’s top at the hot water outlet while the cold water will come through the bottom, which continues the cycle.

What Is the Difference Between a Tank and Tankless Water Heater?

You commonly find tank water heaters in a lot of homes. They usually heat and store water in a reservoir. Usually, the insulated tank will store anywhere from 30 to 50 gallons of water. Typically, a pipe comes from the top to supply hot water. After using the water, water from your water source refills the tank. Next, there’s heating and storing of the new water, continuing the cycle.

When it comes to tankless water heaters, they make use of high-powered burners to quickly heat water as it passes via the heat exchanger, which is then supplied directly to the faucets with no storage tank. Typically, such heaters are powered by electricity or gas. What’s more, they’re relatively more energy-efficient since they only heat hot water when it’s being used.

How Much Electricity Does an Electric Water Heater Use?

A water heater typically heats water in your household to supply you with hot water for your usual daily requirements. Generally, electric water heaters run for 3 hours daily. However, new more efficient types might run for just half the time every single day. Typically, a water heater will use approximately 4000 watts.

Generally, the average use of a household’s hot water is approximately 45 gallons every day. You can reduce your hot water use to reduce electricity usage. You could use cold water to wash your laundry, invest in low-flow faucets and shower heads, take fewer baths and quick showers, and turn off the water while shaving or when brushing your teeth. For those who’re still using an older version, you can also look into purchasing a more efficient and modern water heater.

Types of Water Heaters

There are various types of water heaters in the market. Here are but a few you should consider:

Tankless (On-Demand) Water Heaters

Tankless water heaters never store water, but when you make a hot water demand, it rapidly heats the water that passes via the unit, hence allowing a constant supply of hot water. The point-of-use tankless water heater system makes use of multiple smaller units which you set up throughout the home or other structure. The whole-house tankless water heater system comprises a single water heater that supplies every hot requirement for a whole house.

Storage Tank Water Heaters

Storage tank water heaters are the most common type of water heater with units that have an insulated tank, which allows the heating and storing of water until it’s required. They’re available in liquid propane (LP), electric, and natural gas models. LP and natural gas water heaters are usually less expensive and use less energy to operate compared to electric models of similar sizes. Before you buy a water heater, ensure to check its cited energy efficiency and its annual operating costs.

Heat Pump (Hybrid) Water Heaters

A heat pump (hybrid) water heater is a hybrid unit that comprises an outdoor conditioner and an indoor air handler that reverse surrounding temperatures. Since the air always contains heat energies, a heat pump will draw out those energies and then funnel them indoors during cold days.

Condensing Water Heaters

Like traditional heaters, condensing water heaters comprise a tank. Rather than allowing hot exhaust gases through the flue, and end up losing energy, the condensing heater blows them via a coil at the tank’s bottom. Consequently, they allow up to 96% thermal efficiency.

Solar Water Heaters

Solar water heaters absorb heat directly from the sun and utilises it to heat water. It comprises a solar panel for absorbing the rays of the sun and heating the water, as well as a storage tank. Sometimes, higher-end models have circulation features.

What Are the Benefits of an Electric Water Heater?

Instant Hot Water Supply

They supply hot water directly whenever you want to use them. There’s no need to draw pre-heated water from a storage cylinder, thus eliminating heat losses and saving on electricity usage.

Energy-efficient

You don’t want your utility bills going too high. The water heater’s respective energy factors (EF) determine its effectiveness at producing hot water, identifying the amount of electricity or fuel required to heat your water. Generally, higher EF numbers translate to higher efficiency heaters.

Safe and Environmentally Friendly

They avoid the problems and hazards associated with heating water through a combustion process.

Small and Compact Shape

Their small, compact design enables them to fit in small spaces.

Stable Water Temperature

There’s a maximum temperature setting in your home’s heating, which controls the temperature of the water in your faucets at any given time.

Long Life Expectancy

Typically, gas water heaters last around 8 to 12 years. However, electric water heaters have a relatively long experience, which ranges from 10 to 15 yrs.

Features to Look for in a Water Heater

Capacity-Energy Rating

Considering the tank size is vital with tank-type heaters. To make sure that your home has adequate hot water, it’s crucial to determine the amount of hot water you require on average. For a larger household, you’ll require a larger tank unless you buy a tankless water heater.

First-hour Rating (FHR)

The number determines the number of hot water gallons the unit can supply in one hour. So, if your peak hour demand and FHR match, then your water heater will satisfy your hot water requirements.

Dimensions and Space Required

With a properly sized water heater, you can meet your home’s hot water requirements while running more efficiently. Before buying a water heater, therefore, ensure it’s the right size.

Under-sink or over the sink

Under-sink are made for regions where there’s a cold-water supply through a tap. Under-sink options can often be ideal with more demanding environments, and some can supply hot water to more than a single sink.

Safety Features

There are lots of accessories available that can help in improving the efficiency and safety of your water heater. These include water heater stands, water heater pans, water heater blankets, water alarms, timers, and expansion tanks.

Anti-scale Technology

Some brands have features that lower the accumulation of mineral scale at the tank’s bottom by swirling the water. Although scale can reduce the heating element’s life, you don’t have to go for the fancy features to acquire a lasting water heater. Go for one that has a 12-year warranty, which generally includes a thicker or longer element.

Digital Displays

Assists you in customising operation and monitoring levels. Certain heat/electric pump hybrid water heaters allow you to set a certain vacation mode that makes use of only the heat pump for extra efficiency if you’re away.

Warranty

3-12 years is typically the water heater’s coverage. Often, you will incur a little more for relatively longer-warranty models; they usually have thicker insulation for significantly less heat loss and larger burners or elements that can quicken water heating. It’s prudent that you pick a water heater that has the most extended warranty available.
