Having a reliable hot water system is essential for keeping your home comfortable, yet it's something that is often taken for granted, not until something goes wrong. Whether it's the shock of stepping into a cold shower or hearing odd noises coming from your water heater, these may be signs that it’s time to opt in – change of hot water system.
Understanding when to replace hot water systems can save you from the inconvenience of a total breakdown and even lower your energy bills in the long run. Let’s explore the key signs that indicate it might be time for an upgrade and help you find the perfect system fit for your home. Keep reading to learn more!
Thinking about replacing your hot water system? It’s good to know what options are available, especially since choosing the right one can make a big difference in your comfort and utility bills. Let’s dive into the four main types of hot water heaters available in the Australian market:
Gas heaters are powered by natural gas and LPG are typically efficient, especially in homes that already have a gas line. These systems heat water quickly, making them a reliable option for larger households.
These are among the most common hot water systems used in Aussie households. While they can be a bit pricier to run compared to gas systems, they are easy to install just about anywhere since there’s no need for a gas connection.
If you’re keen on being eco-friendly, solar hot water systems are a brilliant option. They use the sun's energy to heat water, which can slash your carbon footprint and energy bills. These systems also come with backup electric or gas boosters to keep the hot water flowing during those cloudy days. However, Eze-Flow Plumbing does not install solar hot water systems.
These systems pull heat from the surrounding air and are known for their energy efficiency. However, we don't install or recommend heat pumps due to their poor quality and high cost. In fact, you're likely to pay four times more than you would for a high-quality, reputable regular system.
When it comes to hot water systems, aside from the fuel source, there are two main categories to choose from. These are:
These heaters only heat water as needed, making them super efficient. They provide a continuous supply of hot water, which means you’ll never run out mid-shower! On the downside, they do come with higher installation costs compared to traditional storage systems.
It’s also important to note that they require an outdoor GPO for the auto-ignition. At Eze-Flow Plumbing, we work closely with a trusted electrician and can arrange for the GPO to be installed at the same time as your new hot water system to make the process seamless and hassle-free for you.
Storage heaters have a tank that stores a set amount of hot water. These systems can sometimes be a bit less efficient because they keep heating the water even when not in use, but they are often more affordable upfront.
It’s also worth noting that gas storage tanks will reheat in about an hour once empty, whereas larger electric models typically only heat up once a day, which may not suit households with high hot water demand.
It’s important to keep an eye on your hot water unit’s health. If you notice any of the following signs, it might be time to consider the option involving a change in hot water systems:
Water pooling around your hot water system is a clear sign that something's wrong. Leaks are often a result of internal corrosion or faulty parts. If left unaddressed, leaks can cause significant water damage to your home and increased water bills.
If the water coming from your hot water taps looks orange, rusty or smells off, it could mean your tank’s corroding from the inside. Over time, rust can build up and mess with your hot water supply.
Hearing strange sounds like popping or rumbling from your hot water system? That’s usually a sign of sediment build-up. As the sediment hardens, it hardens, it not only makes noise but also reduces your system’s efficiency and potentially leads to damage.
If your water temperature is inconsistent or you’re suddenly without any hot water, it could mean that your system is struggling. This might be down to a failing heating element or thermostat.
Like most appliances, hot water systems have a lifespan. If yours is hitting the 10-year mark or more, it’s more likely to fail and is probably less energy-efficient than newer models. If it's getting on in years, it may be time to replace the hot water unit before it gives up completely.
Each type of hot water system comes with an expected lifespan, though actual performance may vary on the type and proper maintenance. Here’s a general idea of how long each system should last:
Gas Hot Water Systems: Typically last 8-12 years.
Electric Hot Water Systems: Generally last 10-15 years.
Solar Hot Water Systems: Expect about 12 years of service.
Heat Pump Hot Water Systems: Can last up to 10 years.
Tankless or Continuous Flow Water Heaters: These systems can last 15 years or more.
Keep in mind that these are rough estimates. How long your hot water system lasts really comes down to how well it's looked after, along with factors like water quality and pressure. Regular servicing can make a world of difference in extending the life of your hot water system.
Picking out a new hot water system is a big decision, so there are a few things you’ll want to think about before jumping in:
The size of your household affects what kind of system you need. A family of five is going to use a lot more hot water than someone living solo. Make sure you choose a system that can keep up with your daily hot water demands.
Depending on your hot water usage, the location of your hot water system and how much space you have available in your house or unit, you’ll need a system with a capacity that suits your needs. Bigger households should opt for larger tanks or continuous flow systems to avoid running out of hot water during those busy mornings.
Take time to explore the types of hot water systems available. Gas, electric, solar, or heat pump—each has its pros and cons. Consider what works best for your home, location, and budget.
Always go with a licensed professional to install your system. Poor installation can lead to inefficiency and safety issues. It’s worth investing in professionals that can get the job done right the first time.
Upfront costs can vary significantly depending on the system you choose. Consider both the initial purchase price and the long-term savings on energy bills when making your decision.
Storage systems require more room than continuous flow systems. If space is limited in your home, a tankless system might be the better option as it takes up less room.
Energy efficiency is a big deal these days, and for good reason. Choose a system that works efficiently to save on energy costs and reduce your environmental footprint.
