How Much Does it Cost to Replace a Hot Water System?

Replacing a hot water system is a big decision, and understanding the total cost can feel overwhelming. The price of installation isn’t just about the hot water unit itself - it also includes the work of qualified tradespeople, electrical requirements, and any extra parts needed to get your system up and running safely.

What’s Included in Hot Water System Installation Costs?

When budgeting for a new hot water system, it’s important to consider:

Plumbing and electrical labour - both a licensed plumber and an electrician may be required, depending on your system.

The hot water unit itself - electric, gas, solar, or heat pump.

Additional fittings or parts - such as new valves, tempering valves, or pipework.

Compliance and paperwork - such as lodging QBCC Form 4 (or similar forms depending on your state or territory).

System relocation - extra costs apply if your unit needs to be moved.

Removal and disposal - safe disposal of your old hot water system.

Factors That Affect Hot Water System Prices

Installation costs will vary depending on:

- The type of hot water system (electric, gas, solar, or heat pump).

- Whether you’re replacing an existing system or installing one for the first time.

- The complexity of the installation (e.g., relocation, tricky access points, or major electrical upgrades).

Getting the Right Quote

Because every home is different, the best way to know the true cost of hot water system installation is to get a quote from a licensed plumber or gasfitter. For electric systems, you may also need a qualified electrician to ensure everything is wired safely and correctly.

Frequently Asked Questions

What size hot water system do I need?

While the size of the hot water system will more than likely vary depending on your specific needs, the average 4-person Australian home will need at least a 160 litre tank for a continuous electric system, or a 250-315 litre off-peak system. If you’re in the market for a gas tank, a 4-person house averages a 170 litre tank. 270-315 litre tank should be sufficient for heat-pump users. 

Why is the right size hot water system so important?

If your hot water heater is too small for your needs, you will find yourself continually run out of water. On the other hand, if your hot water system is too large for your needs, you are going to spend an unnecessary amount of energy (and therefore money) heating it. This is because your hot water system will keep maintaining the heat of your water, even when you are not using it.

Can I install the system myself?

You will need a licensed plumber to install your new hot water system.

I'm not in SEQLD - how do I choose a plumber?

It's important to ensure you choose the right plumber to install your hot water system. The last thing you want is a non compliant install on your brand new hot water system, which could shorten the life of the new hot water system and even void the warranty. We are often asked if a customer can install a hot water system...in all honesty the risks aren't worth it - and it's illegal! Best to call a licensed plumber to ensure it's done right.

How do I calculate my hot water usage?

The first step to take in choosing a new hot water system is to calculate the hot water usage in your home. The amount of hot water each household uses will vary depending on lifestyle, appliances, and water fixtures throughout the house.
