The Pros and Cons of Electric Hot Water Heaters

Choosing the right hot water system for your home is crucial, and electric hot water heaters are becoming increasingly popular.

As a fuel source, electric systems provide a reliable and efficient way to heat water, making them a favourite for many households. But of course, it won’t be the right solution for everyone.

Let’s take a look at the pros and cons of electric water heaters, so you can determine if it’s the best fit for your needs. You’ll learn how electric hot water systems work, their benefits, potential drawbacks, and why it’s essential to hire a professional plumber for installation and maintenance.

How Electric Water Heaters Work

Before we take a look at the benefits and drawbacks of electric water heaters, let’s first get to know how they work.

Electric water heaters operate by using electric elements to heat the water, either stored in a tank or heated on demand. Storage tank models keep a large volume of hot water ready for use, making them ideal for households with higher hot water demands. On the other hand, continuous flow or instantaneous systems heat water only when needed, offering an endless supply without the need for a bulky tank.

It’s worth noting that, like gas water heaters, each type has its advantages. Storage systems are great for large families, while tankless models provide efficient, on-demand heating.

Three Pros of Electric Water Heaters

So, with that in mind, let’s look closer at some of the key benefits of electric hot water systems.

1. Energy Efficiency

Electric hot water systems are known for being energy efficient. They often boast better insulation than their gas water heater counterparts. This means they typically keep heat loss to a minimum and use less energy to keep water hot.

Many modern electric models come with energy-saving features that reduce electricity consumption, making them an eco-friendly choice. They also convert almost all the electricity they use into heat, which helps to keep energy waste to a minimum.

2. Lower Initial Purchase Cost

One of the key benefits of electric hot water systems is their lower initial cost.

When compared to a gas water heater, an electric water heater is typically more affordable to purchase and install. This is largely due to the simpler installation process, which does away with the need for complex gas connections or a ventilation system.

For many households, especially those on a budget, the reduced upfront expense makes electric hot water heaters an attractive option. Additionally, the wide range of brands and models available on the market ensures that there is a suitable electric hot water system to fit various needs and preferences.

3. Easy Installation and Maintenance

Electric water heaters offer the advantage of easy installation and maintenance. Unlike gas water heaters, they don’t require complex ventilation systems or exhaust pipes. This dramatically simplifies the installation process and helps to reduce initial costs.

Maintenance is straightforward, as electric hot water systems have fewer parts susceptible to wear and tear. Regular checks mainly involve inspecting the heating elements and thermostat, which are easily accessible. This simplicity means fewer service calls and less downtime. Additionally, the absence of a pilot light in electric hot water systems reduces safety concerns.

Overall, their straightforward setup and minimal upkeep make them a convenient choice for homeowners.

Three Cons of Electric Water Heaters

Of course, an electric-powered system might not be the right new water heater solution for your home. They’re not without their possible drawbacks, which can include the following.

1. Higher Operating Costs

While the initial purchase and installation of an electric hot water system might be cheaper, it’s worth noting that the running costs can be higher over time.

Electricity in Australia is generally more expensive than natural gas, leading to higher operating costs for electric water heaters. This can significantly impact your household energy bills, especially if your hot water demand is high. Heat loss from storage tanks can also contribute to increased energy consumption, making these systems less energy efficient compared to their gas counterparts. Therefore, it’s essential to consider the long-term running costs when choosing the right hot water system for your home.

2. Vulnerability to Power Outages

Blackouts happen. We’ve all had our fair share in our lives. Electric water heaters are vulnerable to power outages, which can be a significant drawback.

Unlike gas water heaters, which can operate independently of the electrical grid, electric hot water systems rely entirely on electricity. During a power outage, you may find yourself without hot water, which can be inconvenient and uncomfortable. This reliance on electricity can be particularly challenging in areas vulnerable to regular power cuts.

Some homeowners get around this by using backup generators or solar-powered systems. However, if power reliability is a concern in your area, it’s worth considering this aspect when choosing an electric water heater.

3. Limited Hot Water Supply for High Demand

In larger households, electric hot water systems can struggle to meet high hot water demand.

Storage tank models have a finite capacity, and once the hot water is depleted, you must wait for the tank to heat up again. This can be inconvenient during peak usage times, like mornings or evenings when multiple showers and appliances are in use.

Continuous flow systems address this issue by providing hot water on demand, but they can still struggle if members of the household are using multiple outlets at the same time.

Assessing your household’s hot water needs is crucial to ensure your electric hot water system can keep up with demand.

Making the Right Choice for Your Hot Water Needs

Choosing the right hot water system is crucial for your home’s comfort and efficiency.

Electric water heaters offer many benefits, including energy efficiency, lower purchase costs, and easy maintenance. However, they also come with higher running costs and reliance on electricity. Understanding these pros and cons will help you make an informed decision.

Remember, installation and maintenance by a licensed plumber are a must for optimal performance. Consider your household’s hot water demands and consult with a professional to ensure you choose the best system for your needs.
