With so much discussion around heat pumps and energy efficiency, a lot of homeowners assume gas hot water systems are disappearing.
But across North Lakes and the wider Moreton Bay region, we’re still seeing plenty of households choosing gas hot water systems for one simple reason:
Performance.

For many families, especially larger households with higher hot water demand, gas systems still offer a level of recovery speed and consistency that works very well day to day.
One of the biggest advantages is rapid recovery.
Gas storage systems like Thermann are designed to heat water quickly, which means the system can keep up better during busy periods when multiple people are showering back-to-back.
For households with teenagers, larger families or high morning demand, that recovery speed can make a noticeable difference.
Another reason some homeowners stick with gas is mains pressure performance.
A properly sized gas storage system can maintain strong and consistent hot water pressure across multiple taps and showers at the same time. That becomes important in larger homes where bathrooms, kitchens and laundries may all be in use together.
For some homeowners, reliability and familiarity also play a role.
Many homes across Brisbane and Moreton Bay already have existing gas infrastructure in place, so replacing an ageing gas system with a newer, more efficient unit can be a straightforward and practical option.
Modern systems like Thermann also offer improved efficiency compared to older units, with 4-star energy ratings designed to help reduce ongoing gas usage while still delivering strong performance.
Durability matters too.
Thermann gas systems are built for Australian conditions with features like heavy-duty vitreous enamel lining and larger anodes to help protect the cylinder over time.
And while heat pumps are an excellent option for many homes, they’re not automatically the best fit for every household.
The right hot water system depends on:
- household size
- hot water demand
- available space
- existing infrastructure
- running cost priorities
- long-term usage patterns
At RJT Plumbing & Gas Solutions, we help homeowners choose systems based on what will actually suit the property and household long term, not just what happens to be trending at the time.
And just as importantly, installation quality matters.
Reece ensures every Thermann gas hot water system is installed with compliant valves, precision gas tuning and correct setup for safe, reliable performance.
