Continuous Gas Hot Water Systems

Continuous Gas Hot Water Systems

If you’re tired of running out of hot water halfway through a shower, a continuous gas hot water system may be one of the most reliable upgrades you make.

At Hot Water Boss, we supply high-quality continuous flow gas systems from leading brands including Rheem, Rinnai, Thermann, and Vulcan - giving you access to proven systems that deliver consistent performance for Australian households.

How Continuous Gas Hot Water Systems Work

A continuous flow (instantaneous) gas system heats water only when you need it.

There’s no storage tank and no waiting for reheating. Instead, cold water passes through a heat exchanger and is instantly heated by gas, delivering endless hot water on demand.

This makes them ideal for:

• Larger households
  
• Homes with multiple bathrooms
  
• Families using hot water at the same time
  
• Properties already connected to natural gas or LPG
  

Choosing the Right Continuous Flow Gas System

Getting the right system size and configuration is critical. The two most common mistakes are choosing the wrong flow rate and the wrong gas type.

Flow Rate (Litres Per Minute)

Continuous gas systems are rated by how much hot water they can deliver at once.

• Too small → pressure drops when multiple taps are used
  
• Correct size → consistent temperature across showers, sinks, and appliances
  

For most homes in South-East Queensland:

• 20–26L/min suits families of 3–5 with simultaneous usage
  

Gas Type: Natural Gas vs LPG

Gas systems are not interchangeable between natural gas and LPG.

Before purchasing, you must confirm your property’s gas supply. Converting later is not a simple or cost-effective option.

Other Key Factors to Consider

• Temperature controllers
  Some models include them, others don’t - check before purchasing
  
• Energy efficiency (star rating)
  Higher star ratings mean lower long-term running costs
  
• Installation location
  Internal vs external units depend on ventilation, clearance, and compliance requirements
  

Continuous Gas vs Other Hot Water Systems

If you’re comparing options, here’s how continuous gas stacks up:

Simple rule of thumb:

• Running out of hot water? → Continuous flow solves it
  
• Want to reduce power bills? → Consider a heat pump system
  

Supply vs Installation (Important)

At Hot Water Boss, we specialise in the installation of electric and heat pump hot water systems across South-East Queensland.

For gas hot water systems:

• We supply the unit and accessories
  
  
• Installation must be carried out by a licensed plumber and gas fitter
  
  

This ensures your system is installed safely and complies with Australian standards.
