Gold Coast Gas Hot Water Systems Repairs, Servicing and Installation

First and foremost, we deeply understand gas hot water systems and recognise the importance of a well-functioning system for your family’s comfort and safety.

Although gas hot water systems may have higher initial installation costs, they offer lower running expenses and increased energy efficiency compared to electric alternatives, heating water more effectively and rapidly.

Gas hot water systems, utilising either natural gas or LPG bottle gas, are available in two distinct types:

Storage Gas Hot Water Systems

Gas storage hot water systems store preheated water in an insulated tank, maintaining a constant, ready-to-use temperature with the help of a continuous gas pilot light. The pilot light activates the main burner beneath the tank to heat water as needed.

Gas storage systems resemble electric storage systems, but they reheat water more quickly, providing a faster recovery rate for hot water availability.

One downside to gas storage systems is that it takes time to reheat additional water once the stored hot water is depleted. However, this issue can be minimised by selecting a storage unit with the appropriate rating and recovery capacity for your household’s requirements.

  • Available as either natural gas or LPG
  • Range of storage tank size units depending on the manufacturer – 90L, 130L, 135L, 155L, 160L, 170L

Instantaneous Continuous Flow Gas Hot Water Units

Gas instantaneous, continuous flow, endless on-demand, or tankless hot water units are different names for the same type of gas hot water system. These systems only heat water when you turn on a hot water tap, providing an efficient and virtually limitless hot water supply.

Instantaneous gas hot water units offer high efficiency and a constant stream of hot water, making them an attractive choice for many households.

Instantaneous gas hot water units are standard on the northern Gold Coast from Hope Island north, with natural gas supply to these suburbs.

Gas hot water systems are NOT suitable for DIY work of any kind.

To ensure the safety and well-being of you and your family, it is crucial to exclusively rely on licensed gas professionals for all installation, maintenance, and repair tasks. Failure to do so may result in severe consequences, including personal injury or property damage.

Please prioritise your safety and the safety of others by always choosing qualified experts for any gas hot water system work.

Replacing Your Gas Hot Water System

Selecting the suitable gas hot water system from the vast array of options on the market can be challenging, but ensuring the system is correctly sized for your needs is crucial.

Gas hot water systems offer several advantages over electric alternatives:

  • Lower running costs for heating water.
  • Increased energy efficiency with new 4-star and 5-star rated models.
  • Consistent gas pricing without time-of-day cost fluctuations, unlike off-peak electric rates.
  • Availability of both natural gas and LPG versions for all models.
  • Reduced greenhouse gas emissions.

When replacing “like for like” storage gas hot water systems or instantaneous gas units in Queensland, it’s legally required to upgrade all valves, insulation, and overflows to comply with current standards set by the Plumbing and Drainage Act 2018, which incorporates the relevant Australian Standards AS/NZS 3500.4:2021 and AS/NZS 5601.1:2022.

Natural gas units are the most eco-friendly hot water systems compared to electric or LPG options. Remember that the higher the star rating of the gas hot water unit, the greater its efficiency and cost-effectiveness.

When a gas hot water system fails, it often does so with a bang or a flood, typically due to gas faults, blown valves, or holes in the tank—leaving you with little warning.

At Whywait Plumbing, we can provide same-day “like-for-like” gas hot water system replacements to minimise disruptions.

When a Whywait Plumbing Technician is dispatched to replace your hot water system, they will:

  • Recommend a suitable system for your home and your family’s needs.
  • Ensure compliance with relevant Queensland legislation.
  • Offer a range of solutions along with guaranteed upfront pricing.
  • Upgrade all valves and fittings to AS/NZS 3500.4:2021 requirements.

Maintenance and Servicing of Gas Hot Water Systems

Working on gas hot water systems legally requires a licensed Plumber and Gas Fitter, as gas—much like electricity—can be dangerous if not handled correctly.

Although gas can often be detected by its smell, the risks of improper installation and maintenance of gas hot water systems on the Gold Coast can lead to potentially catastrophic consequences.

Don’t gamble with your safety by opting for a substandard installation. Instead, choose Whywait Plumbing for maintaining, servicing, or installing your gas hot water system, and ensure the job is done correctly and safely.

Avoid putting yourself or your family at risk with DIY repairs. Both gas and electricity can cause severe injuries or even death when mishandled.

Remember, there are no DIY options for gas hot water systems. Always rely on licensed professionals to keep you and your family safe.

Google Review

“Had the hot water system blow on our 20 year old property, called why wait and had a professional on our door within an hour. System needed a complete replacement due to its age and had a great recommendation from Gary that’s been going great ever since.

Just had the toilet system reach it’s end of life as well so called WhyWait and exact same great experience again. Response within an hour, inspection and advice on solution, came out the very next day with the systems and replaced them in time fro Christmas. Can’t recommend Gary and WhyWait enough if you’re ever stuck and need a professional, quick resolution to your plumbing needs.”
