How To Know You’re Choosing The Right Licensed Installer For Your New Hot Water System

Are you concerned about picking the right hot water system for your home or office?

There are a lot of considerations when choosing a new system, like size, price, type, and whether or not the installer in licensed to install your hot water system.

What is the right type of hot water system for me?

When selecting the correct type, brand, and size of hot water system for your home or office there are some considerations to think through first.


It’s important to get it right at the start as the new unit is going to be a long term investment.

Things to consider when choosing the right system for you:

  • What energy source is available? Gas, electricity, or solar? 
  • What size unit is best suited for your family or workplace? How many people will use it? And how often will it be in use?
  • Where will the new unit be located vs. the distance of pipework to run to the furthest hot water outlet?
  • Do you have any mandatory electrical, plumbing, or gas safety upgrades required for a new installation?

How do I know I'm getting my hot water system installed at a fair price?

There’s no doubt the hot water industry is a competitive marketplace, however it’s not uncommon to hear about customers paying too much or too little for a hot water heater installation. 


A good and fair price for a hot water system that is installed correctly will generally be between $1500 and $2000 depending on the brand, type, and size of hot water heater. 


Owners should be wary when selecting a licensed plumber to install their new hot water heater. Installing it in the correct and compliant way has a price.

Things to consider when choosing the right price:

Too cheap could mean:

  • Not a licensed plumber
  • Form 4 notifiable works are not being submitted to QBCC
  • Illegal installation (non-compliant, could void HWS or homeowner insurance/warranty)
  • Cheap and poor quality valves or parts are being used
  • Cheap and poor quality hot water system is being used (unfortunately, they are out there)
  • Rushed job with poor attention to detail
  • Not upgrading electrical circuits or installing an RCD

Too expensive could mean:

  • Not an honest or fair company
  • Third-party kick backs are involved
