What Information Do You Need to Choose the Best Gas Hot Water System?

When it comes to gas hot water systems for domestic use, three main options ensure you stay out of a cold shower:

• Storage Systems

• Continuous Flow Systems

• Instantaneous (Instant) Gas Hot Water Systems

Before selecting a system, it’s important to understand what you are purchasing, the research and data behind the system, and why these factors matter.

Understanding Compliance & Standards

All domestic gas hot water systems from major brands comply with the Plumbing Code of Australia (PCA) and carry WaterMark certification. Your plumber acts as the link between these regulations and your installation. Choosing a PCA and WaterMark-approved system ensures the highest standards of safety and performance.

How Gas Hot Water Systems Work

A basic understanding of how hot water systems operate can empower you to make informed decisions rather than relying solely on salespeople or installers.

Storage Gas Hot Water Systems

• Function similarly to a boiling pot on a stove.

• A burner inside the tank heats a large volume of water.

• A thermostat regulates gas flow to maintain the set temperature.

• Works independently of electricity, making it reliable during power outages.

Continuous Flow & Instantaneous Gas Hot Water Systems

• Do not store hot water; instead, heat water on demand.

• Large burners rapidly transfer heat to flowing water.

• Operate similar to a hose left in the sun where heat is absorbed instantly.

• More energy-efficient than storage systems.

• Electronic controls and fan-forced combustion deliver cost-effective operation.

Choosing the Right Gas Hot Water System

Once you understand the differences, consider how these factors impact your decision:

1. Installation & Running Costs

• Natural Gas: Affordable over 10 years, including installation and maintenance.

• LPG Gas: Higher running costs, comparable to peak tariff electric systems.

• Solar Hot Water: Higher upfront installation costs but significant long-term savings.

2. Environmental Considerations

• Highly efficient options: Solar, heat pumps, and natural gas.

• Less efficient options: LPG, which is petroleum-based and relies on coal-fired power in Queensland.

• Sustainability: Solar and natural gas systems help reduce your carbon footprint.

3. Finding a Reliable Installer

• Read reviews on Google, Product Review, and trade websites.

• Consider both positive and negative customer feedback.

• Look into staff turnover and how the company handles customer questions.

• Avoid installers who push a single brand instead of providing options tailored to your needs.

4. Selecting the Right Size System

• Work with your plumber to choose the optimal size.

• Refer to a hot water help guide for general sizing recommendations.

• Household size and water usage patterns will determine capacity requirements.

Why Timing Matters

Gas fitting and plumbing systems may look simple in principle but are complex in design and operation. Doing your research before your current system fails ensures you make a well-informed decision rather than rushing into an expensive, impulse purchase when faced with an unexpected cold shower.
