Replacing an Electric Hot Water System: What You Need to Know
Replacing an electric hot water system can seem daunting, but it’s a step that eventually comes for every homeowner. Whether your water heater is struggling to keep up with daily demands, making strange noises, or just plain old, an upgrade can bring major benefits.
A new electric hot water system can mean greater energy efficiency, lower utility bills, and more reliable hot water. But how do you know when it’s time to replace it, and what factors should you consider when choosing a new one?
In this guide, we’ll walk you through the essentials, from spotting signs it’s time for a replacement to understanding the different options available. Let’s take the guesswork out of this important home upgrade, so you can enjoy worry-free hot water for years to come.
Signs It’s Time to Replace Your System
Here are some clear signs that it may be time to replace your electric hot water system:
- Inconsistent water temperature: If your showers suddenly switch from hot to cold without warning, it could mean the system is struggling to keep up or that the heating elements are wearing out.
- Reduced hot water capacity: Running out of hot water faster than usual? A dwindling supply often indicates an ageing system or sediment buildup in the tank, which reduces efficiency.
- Strange noises: Unusual sounds like banging, popping, or hissing often mean there’s a buildup of sediment inside the tank, forcing the system to work harder than it should.
- Leaks around the tank: Notice any water pooling near your hot water system? Leaks often signal a structural problem, and if left unaddressed, they can lead to water damage.
- Higher energy bills: An old or inefficient system may consume more energy to deliver the same results, leading to noticeable increases in your utility bills.
If you’re seeing one or more of these signs, it may be time to consider a replacement before a breakdown occurs.
Choosing the Right Replacement
When it comes to choosing a replacement for your electric hot water system, a few key factors can help you find the perfect fit for your home.
First, think about capacity − larger households usually need systems with a higher storage capacity or a more robust continuous flow system to meet daily demands.
Next, consider energy efficiency. Modern electric hot water systems are designed to be more energy-conscious, which can help reduce electricity bills. Look for systems with high energy ratings or advanced technology, such as smart thermostats, to boost efficiency.
Your budget is another important factor, as both the system’s price and installation costs vary widely. However, keep in mind that investing in an energy-efficient model may save you money in the long run. Lastly, think about installation requirements.
Some systems may need adjustments to your existing plumbing or electrical setup, so it’s wise to consult with a professional installer to get an accurate idea of what’s involved. Balancing these factors will help you find a replacement that best suits your household’s needs.
Storage Tank vs Continuous Flow
When replacing your electric hot water system, you’ll come across two main types: storage and continuous flow. Each has its pros and cons, so understanding the difference can help you choose the best option for your household.
Storage systems heat and store water in a tank, ready for use at any time. These are ideal for homes with high, predictable hot water demand, as you’ll have hot water available even if multiple people are using it simultaneously. However, because they keep water hot constantly, they can be less energy efficient.
On the other hand, continuous flow systems, also known as tankless systems, heat water on demand, so there’s no need to store hot water. This setup is more energy-efficient since it only heats water when needed.
The trade-off is that it may struggle to supply hot water to several outlets at once. Continuous flow systems are great for smaller households or those looking to reduce energy costs. Weighing these differences will help you decide which system fits your home’s needs best.
Steps Involved in HWS Replacement
Here’s an overview of the key steps involved in replacing an electric hot water system. These steps must be carried out by a qualified plumber − it is not a DIY job − but it can’t hurt to understand the procedure:
- Turn off power and water: Before starting, the power to the existing hot water system needs to be switched off to ensure safety. The water supply should also be turned off to prevent leaks during removal.
- Drain the old system: The old system must be completely drained to avoid water spillage. This step may involve connecting a hose to the drain valve and directing the water to a safe drainage area.
- Disconnect plumbing and electrical connections: A professional will carefully disconnect the existing water and electrical connections, ensuring that no live wires or water pressure remains in the system.
- Remove the old system: Once disconnected, the old system can be safely removed. Some installers will dispose of the old unit as part of their service.
- Install the new system: The new hot water system is connected to your plumbing and electrical systems, with adjustments made as needed to fit the new model.
- Test and inspect: After installation, the new system is tested for functionality and any potential leaks, ensuring it’s ready for use.
Hiring a licensed professional is absolutely necessary to ensure safety and compliance with local regulations.
Cost Breakdown of HWS Replacement
Replacing an electric hot water system involves several costs and knowing what to expect can help you budget effectively. The biggest expense is usually the new system itself, with prices varying based on size, brand, and energy efficiency.
Basic storage tank models tend to be more affordable, while tankless or high-efficiency systems may come with a higher price tag due to their advanced features.
Next, you’ll need to factor in installation costs. Hiring a licensed professional is essential for safety and compliance with local regulations, and this typically adds to the total. Installation fees can vary depending on your home’s layout and any adjustments needed to the plumbing or electrical systems.
Additional costs might include old system disposal fees, if not included by the installer, and any upgrades required to meet current safety standards. It’s also worth exploring any government rebates or incentives for energy-efficient models, which can help offset costs.
In the end, investing in a quality, efficient system can lead to long-term savings on energy bills and fewer repairs down the line.
Maintaining Your New Hot Water System
To keep your new electric hot water system running efficiently and extend its lifespan, regular maintenance is key.
Here are some simple steps:
- Flush the tank regularly: Sediment buildup can reduce efficiency and even cause damage over time. Flushing the tank every six months removes sediment and helps maintain heating performance.
- Inspect the anode rod: The anode rod prevents tank corrosion, but it wears out over time. Have a professional check it every few years and replace it when needed to protect the tank’s interior.
- Check for leaks: Regularly inspect around the tank and connections for any signs of leaks. Early detection can prevent more significant water damage and expensive repairs.
- Schedule professional maintenance: Yearly check-ups by a licensed technician can help spot issues early and ensure the system is running efficiently.
Following these steps can help you enjoy reliable, efficient hot water for years to come, with fewer unexpected breakdowns or repairs.
Maximise Your Investment
Replacing your electric hot water system may seem like a big task, but the benefits of a new, efficient model make it well worth it. A new system can provide more reliable hot water, lower energy bills, and peace of mind knowing you won’t be caught off guard by a sudden breakdown.
From recognising when it’s time for a replacement to understanding the types of systems available, you now have the essential knowledge to make an informed choice.
Remember, choosing the right model, budgeting for installation and staying on top of maintenance can help you maximise your investment. If you’re considering an upgrade, consult with a licensed professional to ensure a smooth, safe installation. With the right system, you’ll enjoy hassle-free hot water for years.
