Choosing the Right Hot Water System: A Guide to Electric Hot Water Systems

Let’s face it – when your hot water system dies, it tends to die suddenly (and at the most inconvenient time, too). We use hot water for so many things around the home – from bathing to washing dishes – so the system often needs to be replaced quickly, which doesn’t leave much time for research. Most people just get a newer version of the one they already had. But what if you’re missing out on a better option? In this guide, we’ve taken a closer look at electric systems and how they can benefit you.

How do electric hot water systems work?

They might seem complicated at first glance, but electric systems are actually fairly simple. They operate on the principle of heating water via immersion elements and thermostats. When cold water enters the system, it passes through an immersion element. This element is heated up via an electrical current, then transfers heat to the surrounding water. When you turn on one of the hot taps in your house, the heated water is delivered to the faucet, ready for use. Meanwhile, the temperature of the water is regulated by a thermostat (to avoid it being too hot or too cold).

What types of electric system are available?

There are two types to choose from – storage and instantaneous (also known as continuous flow or tankless). Storage systems heat water and then store it in an insulated tank until it’s needed, whereas instantaneous systems heat water on demand as it flows through, eliminating the need for a tank.

Each system has its advantages and disadvantages, so there is really no wrong choice. Ultimately, the best choice for your home and family will depend on your specific needs.

  • Household Hot Water Needs

    The first step in choosing a system is to assess your household’s hot water needs. This will largely depend on the size of your household (as larger families will need more hot water), but may also be impacted by other factors (such as your profession, the amount of time you spend at home, and so on).
  • Balancing Cost and Efficiency

    While cost is important, you also need to consider the system’s efficiency. Keep in mind that a more efficient system will use less energy, which can lead to lower running costs. Highly efficient electric systems include heat pump (which use 30% of the energy that are conventional system does), solar, and tankless water heaters.

What are the advantages of modern electric systems?

Modern hot water heaters offer an abundance of benefits over their more traditional counterparts, which is why they’ve become such a popular choice for homeowners.

  • Energy Saving Features

    One of the biggest advantages to these systems is their energy saving features. Heat pump technology, for example, has helped to minimise wasted energy, while high-efficiency electric resistance water heaters are significantly more energy efficient than other models (saving households hundreds of dollars in running costs each year).
  • Enhanced User Controls

    Modern systems also offer advanced controls and settings, which provide you with the ability to conveniently manage your preferences. Some of these features include temperature adjustment, smart control panels or smartphone apps, and thermostat regulation (to maintain your desired water temperature).

How do running costs compare to energy savings?

It’s important to keep in mind that electric hot water systems can be more expensive to run over the long term (due to the higher costs of electricity compared to natural gas), however, there are ways to reduce their running costs. You can take advantage of off-peak tariffs (which is when cheaper energy prices are offered during specific periods, usually late at night), and you should ensure that your system is properly insulated to reduce heat loss. Foam insulation and pipe lagging are common types of insulation that contribute to energy savings.

Choosing the right electric hot water system is an important decision, not only for the comfort of your household but also for your bank account. By understanding the basics of these systems, the differences between storage tank and instantaneous styles, and how to properly assess your household’s hot water needs, you’ll be able to make an informed decision. When selecting a system, be sure to consider its efficiency, cost, and reliability – and take advantage of incentives and rebates!
