Electric hot water systems have become a cornerstone of modern households, delivering unmatched convenience and efficiency. As one of the most widely chosen solutions in Australian homes, almost 50% of residential water heating relies on this practical option. Their ability to provide consistent hot water for everyday use has revolutionised how we think about water heating.
Unlike traditional gas storage or heat pump hot water systems, electric units excel in versatility, catering to various household needs. Whether it’s a hot water heater with a storage tank or an instant electric system, these options ensure reliable access to heated water without significant heat loss.
With advancements in technology, this type of hot water system has evolved to meet modern demands, offering energy efficiency and seamless performance. For households in search of dependable water heating, an electric system is a reliable and forward-thinking choice.
What Is an Electric Hot Water System and How Does It Work?
An electric hot water system is a reliable and efficient way to provide heated water for residential use. These systems operate using electricity to heat water, with an electric element warming the water to the desired temperature. Their flexibility makes them suitable for households of all sizes and varying water demands.
There are two main types of electric water heaters:
a. Electric Storage Tank Systems
Electric storage tank systems operate by heating and storing water within an insulated tank, ensuring a steady supply of hot water is readily available. These systems are designed to cater to households with higher water demands, offering tank capacities ranging from 25 litres to over 400 litres.
The water is kept at a set temperature by an electric element, ensuring it’s always ready for use. While these systems are incredibly reliable, they are better suited for homes with consistent water usage, as the stored water may cool over time, requiring reheating.
b. Electric Instantaneous Hot Water Systems
Electric instantaneous hot water systems, also referred to as on-demand systems, heat water as it flows through the unit. They don’t require a storage tank, making them compact and ideal for homes with limited space. These systems are energy-efficient, as they only use electricity when hot water is needed, eliminating standby heat losses.
Benefits of Electric Hot Water Systems
Electric hot water systems have become a preferred choice for many households. They offer solutions that cater to a variety of needs, from energy efficiency to reliable performance, making them an excellent alternative to gas storage systems or heat pump water heaters.
1. Reliable Hot Water Supply for All Households
Electric hot water systems deliver a dependable supply of heated water for households of any size. Unlike gas storage or instantaneous gas units, they maintain consistent water temperature during peak demand. Running a hot tap in the kitchen or taking a shower won’t interrupt their ability to heat water quickly and efficiently.
2. Wide Range of Models to Fit Every Budget
Finding the right hot water system is simple with numerous water heater types available. From traditional hot water storage systems to continuous flow electric systems, there’s a model to suit every requirement. New hot water systems come in various capacities, ensuring the right fit for small homes or large families.
3. Simple Installation and Maintenance
Electric systems are easier to install compared to heat pump systems or instantaneous gas systems. Maintenance is straightforward, as most components, such as the element and thermostat, are easy to service.
4. Energy-Saving Potential with Modern Systems
Modern continuous flow water heaters, especially continuous flow electric models, are designed to reduce energy usage. Unlike off-peak systems or gas storage systems, which can suffer from standby heat losses, these systems heat water only when needed. A study revealed that modern electric instantaneous systems can significantly cut standby energy losses, saving households both electricity and money.
5. Compatibility with Solar Systems for Efficiency
Electric water heaters can seamlessly pair with solar energy setups, including PV systems, to reduce reliance on the grid. Combining a solar system with a new hot water system ensures maximum energy efficiency. For larger homes, placing a solar-compatible system at the top of the tank allows for faster energy transfer, further reducing costs.
Electric hot water systems are versatile, offering everything from traditional hot water storage systems to advanced heat pump water heaters, making them an ideal choice for reliable, energy-efficient water heating solutions.
Comparing Electric and Gas Hot Water Systems
Electric and gas hot water systems are two of the most common hot water units in Australian homes. Each has unique advantages based on installation costs, energy efficiency, and climate performance.
Electric Hot Water Systems
- Standard electric hot water systems are easier to install and maintain, making them ideal for most households.
- These systems are usually more energy-efficient when paired with renewable energy sources like solar panels.
- Continuous flow or instantaneous electric units heat water on demand, reducing standby energy losses.
Gas Hot Water Systems
- Gas water heaters are often preferred in areas with limited electricity availability.
- Gas systems are usually more effective in colder climates, ensuring consistent performance.
- Many gas hot water systems use a gas or electric booster for additional heating, especially in high-demand situations.
Both types of water heaters sold in Australia cater to varying needs. Electric systems excel in convenience and maintenance, while gas systems may be better suited for homes aiming to balance water and energy costs in specific climates.
Choosing Between Storage Hot Water and Continuous Flow Systems
When selecting a hot water system, it’s important to weigh the benefits of storage and continuous flow options. Each type is designed to cater to different water usage patterns and household needs.
a. Storage Hot Water Systems
Storage systems heat and store water in an insulated tank, ensuring a steady supply for multiple hot water outlets.
- Popular tank sizes in Australia include 25L, 50L, 125L, 250L, and 400L, with larger tanks suited for households requiring significant hot water per day.
- These systems are ideal for families with high simultaneous water demands, such as running showers, taps, and appliances simultaneously.
- Over time, storage systems lose heat, requiring additional energy to maintain water temperature. Selecting the right tank size is crucial to avoid overuse or shortages.
b. Continuous Flow Hot Water Systems
Also known as instantaneous hot water systems, these units heat water only when a hot tap is turned on.
- Water is only heated as needed, making them energy-efficient and reducing standby energy losses.
- Compact in design, they’re an excellent option for homes with limited space.
- They are considered an efficient form of electric heating and can integrate with heat pump or solar hot water systems for added efficiency.
Comparison: Households with high water demands often benefit from storage systems, especially with larger tanks like the 250L or 400L sizes. In contrast, instantaneous systems suit smaller homes or those prioritising energy efficiency and space-saving solutions.
Installation and Maintenance Tips for Electric Hot Water Systems
Proper installation and routine maintenance are essential for the safety and longevity of electric hot water systems. These systems are ideal for households seeking reliable and efficient water heating, but ensuring they function optimally requires attention to detail.
Installation Tips
- Always go for professional installation to guarantee safety and compliance with regulations.
- Ensure the system is placed in a location where water will be pushed efficiently to all outlets.
- Electric systems are available in various models, so choose one that aligns with your household’s water usage and space requirements.
Maintenance Tips
- Regularly check for leaks around the tank, pipes, or fittings to prevent water damage.
- Inspect the heating elements periodically to ensure they’re functioning correctly.
- Make sure the water temperature is controlled properly by testing and adjusting the thermostat if needed.
- Turn the hot water system off during extended absences to conserve energy.
