For Strong, Consistent Performance
Running out of hot water mid-shower is frustrating, especially in busy households where demand comes in waves. At Oxplumb, we work with gas hot water systems across the Sunshine Coast, helping homeowners, landlords and builders restore reliable hot water through repairs, servicing and new installations that suit the way a property is actually used.
Gas hot water systems are designed to deliver strong, consistent performance when they are selected and installed correctly. Gas systems can be storage or instantaneous, and each setup has strengths depending on household size, usage patterns and gas supply.
Storage units suit steady demand, while instantaneous systems heat water on demand and can free up space. Issues such as fluctuating temperature, ignition failure, low pressure or delayed heating are often linked to gas supply, sizing, ventilation or worn components rather than the unit itself.
A proper assessment checks flow rates, burner condition, gas pressure, flueing and compliance so the system operates safely and efficiently. The aim is to deliver hot water that feels consistent, dependable and cost-effective, without unnecessary upgrades.
All our installations meet Australian Standards and come with a certificate of compliance upon completion. If hot water performance has dropped or a system needs replacing, call (07) 2111 7471 to book gas hot water system repairs, servicing or installation on the Sunshine Coast.

Designed For Daily Demand
Gas hot water systems work best when the whole setup is balanced, not just the unit itself. Burner condition, heat exchangers, valves and regulators all influence how quickly water heats and how stable the temperature feels at the tap.
Ventilation and flueing are critical for safety and performance, and even small faults can lead to ignition issues, shutdowns or uneven heating. Routine servicing helps identify wear early, keeping components clean and allowing adjustments before problems become disruptive.
Choosing the right system also matters for long-term satisfaction. Undersized systems struggle during peak use, while oversized units can waste energy. Installation quality affects accessibility for servicing, noise levels and future compliance.
For ageing systems, planned replacement avoids sudden failure and reduces the risk of property damage. Explore the full range of hot water services to compare options, then get in touch to organise the right solution for your household.

FAQs
Everything You Need To Know
Are gas hot water systems cheaper to run than electric?
Running costs depend on gas pricing, household usage and system efficiency. Gas systems often heat water faster than electric storage units and can be cheaper to operate for larger households with high demand. Instantaneous gas systems avoid reheating stored water, which can reduce wasted energy when hot water use is spread throughout the day.
Why does my gas hot water temperature keep changing?
Fluctuating temperature can be caused by low gas pressure, incorrect sizing, blocked filters, scale build-up or worn valves. In instantaneous systems, sudden changes in flow from other taps can affect temperature if the unit cannot adjust quickly enough. Proper diagnosis checks gas supply, flow rates, burners and internal controls to stabilise performance.
Is gas hot water safe for homes?
Gas hot water is safe when installed and maintained correctly. Safety depends on proper ventilation, compliant flueing and correct gas pressure. Faults such as blocked flues or damaged components can create risks if left unchecked. Licensed gas fitting work and routine inspections help ensure safe operation and peace of mind.
Do gas hot water systems need regular servicing?
Yes, regular servicing helps maintain safety, efficiency and reliability. Servicing checks burners, ignition, valves, heat exchangers, flueing and gas pressure. It also confirms the system meets current safety requirements. Without servicing, minor faults can lead to poor heating, shutdowns or increased gas use over time.
Should an old gas hot water system be repaired or replaced?
Repair may suit newer systems with isolated faults, while older units nearing the end of their lifespan are often better replaced. Frequent breakdowns, rising repair costs, reduced efficiency and parts availability all influence the decision. Replacement can improve performance, lower running costs and reduce the risk of sudden failure.
