The Dangers of Installing a Hot Water System Yourself
Installing a hot water system yourself can lead to serious problems. If set up incorrectly, it may fail and cause costly damage. A professional ensures safe installation and prevents unnecessary repairs.
Choosing the Wrong Size System
Buying the wrong-sized system leads to higher bills and frequent hot water shortages. A system too small will struggle to keep up, forcing it to work harder and wear out faster.
The right size depends on household water usage. A 3-4 person family needs:
- Electric models: 182-400litres
- Gas models: 151 litres (low use) or 189-227 litres (high use)

Legal Requirements for Installation
In Australia, only a licensed plumber can install a hot water system. While no special permit is required, the plumber must register a notifiable work form with the QBCC.
This rule applies to replacing, removing, or installing a system in existing homes or extensions. Installing a system without the proper knowledge can lead to serious damage and safety risks.
Difficult Installation Locations
Some hot water systems are installed in tight spaces like attics or under floors. These locations make replacement difficult, even for professionals.
A hot water system weighs 55-70 kilograms, making it dangerous to move alone. Attempting this without help risks injury and system damage.
The Danger of Dry Firing
Hot water heaters must be filled before turning on power. Running dry can overheat copper elements and destroy them.
With water, elements stay 1°C above water temperature. Without water, they heat to 1035-1100°C. This extreme heat can cause immediate or delayed failure.
Signs of Dry-Fired Elements
You can check for dry firing in three ways:
- Soft, easily bent tubing (annealed metal).
- Burned or melted zinc plating exposing copper.
- Melting near the screw plug on Sandhog elements.
