Choosing the Right Plumber for Hot Water System Installation

  • By Hot Water Boss

Published: Tuesday, June 17, 2025

When it comes to installing a new hot water system, choosing the right plumber is essential. A poor or non-compliant installation can shorten the lifespan of your system, cause ongoing performance issues, and even void your warranty.

 

At Hot Water Boss, we’ve been installing hot water systems in Jimboomba and surrounding areas for nearly 15 years. Here’s why it’s so important to use a licensed plumber - and what to look for when choosing one.

Can You Install a Hot Water System Yourself?

We’re often asked whether customers can install a hot water system themselves. The short answer? No - it’s illegal.

 

Only a licensed plumber is legally allowed to install hot water systems in Australia. Attempting to do it yourself could:

- Breach local plumbing and safety laws.

- Void your hot water system warranty.

- Lead to leaks, electrical faults, or costly repairs down the track.

 

The safest and smartest option is always to hire a qualified professional.

What to Look for in a Hot Water Plumber

Not all plumbers are the same. When choosing a plumber for your hot water system installation, here are the key things to check:

 

✅ Licensing is a Must

Always ask to see a plumber’s license. A reputable professional will be happy to provide proof.

 

✅ Gas Fitting Endorsement (If Needed)

If you’re installing a gas hot water system, your plumber must also hold a valid Gas Fitting License.

 

✅ Experience with Your Type of System

Some systems - such as solar hot water systems and heat pumps - require additional training and license endorsements. Make sure your plumber has specific experience with the system you’re installing.

 

✅ Good Communication and Customer Service

Technical skills matter, but so does customer service. Look for a plumber who is:

- Responsive and easy to contact.

- Respectful of your home and time.

- Clear and upfront about pricing.

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.
