Making a Decision on Hot Water Systems

Thinking of replacing your hot water system? Discover the top 10 essential questions to ask before buying a new unit, and make a smart, long-term decision for your home.

Time to Upgrade Your Hot Water System?

There’s nothing quite like the shock of a cold shower to remind you how important hot water really is. We rely on it daily—for showers, washing dishes, doing laundry—and yet, we often don’t think about it until the system gives out.

If your current unit’s on its last legs or just not keeping up with your household’s needs, now’s the time to look into a replacement. But choosing a new hot water system isn’t a one-size-fits-all decision. The wrong choice could lead to high power bills, wasted water, and daily frustration.

That’s why we’ve put together this top 10 checklist to help you make an informed, stress-free decision that suits your home, budget, and lifestyle.

Top 10 Questions to Ask Before Buying a Hot Water System

1. How’s Your Shower Routine?

Think about how your household uses hot water. Is there a morning rush? Do you have teenagers who love long showers? Or is hot water mostly used in the evenings? Your usage habits will help determine the right size and type of system.

2. What Energy Sources Are Available?

Check what you’re already connected to—electricity, gas, or solar. Sticking with the same source may save on installation, but switching could mean better energy efficiency and long-term savings.

3. What Type of System Suits You?

There are a few types to choose from:

  • Storage Systems (keeps hot water ready to go)
  • Continuous Flow (Instant) (heats water as you use it)
  • Heat Pump Systems (energy efficient, works like an air con in reverse)
  • Solar Hot Water (great for reducing bills and your carbon footprint)

Each has pros and cons depending on your climate, budget, and water usage.

4. Which Brands Can You Trust?

Not all hot water systems are built the same. Some brands are better for certain systems—like solar or instant. Do a bit of research, read reviews, and ask your plumber which ones they recommend.

5. Keen to Go Green?

Water heating is one of the biggest energy users in Aussie homes. If sustainability matters to you, consider solar, heat pumps, or high-efficiency gas systems to reduce your environmental impact (and possibly earn government rebates too).

6. What’s the Total Cost—Now and Later?

Don’t just look at the sticker price. Some cheaper systems might cost more to run over time. Weigh the upfront costs against running costs, maintenance, and expected lifespan.

7. Got the Space?

Live in a unit or have a tight laundry or yard? No worries—there are compact models designed for smaller homes. Your plumber can help you find one that fits your space without compromising performance.

8. Is the Warranty Worth It?

Check the manufacturer and installer warranties. Look for systems that offer solid coverage—ideally 5+ years—and make sure the installer backs their work with a workmanship guarantee too.

9. Is Your Installer Reputable?

Choosing the right system is only half the battle—it also needs to be installed properly. Go with a licensed plumber who specialises in hot water systems and can tailor the setup to your home’s specific needs.

10. Have You Spoken to a Hot Water Specialist?

This isn’t a decision you want to rush. Chat to a professional who can assess your home, usage, and budget, then guide you through your options. It could save you heaps in the long run.
