Hot water not working? Replacing your hot water system might not seem like a big deal, until it suddenly is. Most people don’t give it a second thought until they are staring down a cold shower or a leaking tank. That’s when the pressure kicks in, and too often, we see rushed decisions that end up costing more in the long run.

At ABA Plumbing & Gas, we have been called out to fix more than our fair share of hot water dramas many of which could have been avoided with the right advice upfront. If you are considering a hot water replacement in Adelaide, here are six traps we see all the time (and how you can steer clear of them).

1. Going for the Cheapest Option Without Thinking Long-Term

We get it that nobody wants to spend more than they have to. But when it comes to hot water systems, the cheapest option on the shelf can come back to bite. It might lack efficiency, be made with cheaper parts, or need replacing again sooner than expected. In the end, paying a bit more for a trusted brand and solid warranty usually saves you money (and headaches).

2. Underestimating How Much Hot Water You Actually Use

It’s easy to assume any system will do the job, but your household’s size and daily routines make a big difference. A couple living in a unit has very different needs compared to a family of five with two bathrooms. Too small, and you’ll be racing the clock for a hot shower. Too big, and you are wasting money heating water you don’t need. It’s worth getting this part right.

3. Thinking You Can DIY the Installation or Get a “Mates Rates” Job

We have lost count of how many DIY or cheap installs we have been called in to fix. A proper installation isn’t just about connecting a few pipes – it’s about making sure the system runs efficiently, safely and within warranty guidelines. When it comes to gas, electricity, or even just long-term performance, don’t take risks. A licensed installer gives you peace of mind and the paperwork to back it up.

4. Ignoring Energy Efficiency Ratings

A hot water system is one of the biggest energy users in your home, second only to heating and cooling. Choosing an energy-efficient model isn’t just good for the planet – it directly affects your bills. It might cost a little more upfront, but if it saves you month after month, it’s a smart move. Ask us about the best options for your home and budget.

5. Installing It in a Tight Spot Without Thinking About Future Access

This one’s often overlooked until it’s too late. We have seen systems jammed into corners, under stairs, or behind walls that make basic maintenance a nightmare. If a plumber can’t reach it easily, that simple fix you will need in five years might turn into a full-day job. When replacing your system, think ahead. Make space for future-you and your plumber.

6. Forgetting That Your Life Might Change

Maybe you are renovating soon. Maybe your kids are getting older and taking longer showers. Or maybe you’re planning to rent out your property down the track. Don’t just replace your system for today….think about what life might look like in a few years. A little planning now can save you from replacing it all over again.
