Which Gas Water Heater Is Best For Your Home

Are you in the market for a gas water heater? Choosing the right one for your home can be a daunting task. In this blog, we’ll address common FAQs and provide expert advice to help you make an informed decision.

Tank Type Gas Water Heater

When it’s time to replace an old water heater, you’ll need to decide which type of new gas water heater best suits your home and lifestyle. There are several factors to consider, such as size, energy efficiency, installation requirements, and operating costs.

You’ll also need to choose a size - usually 30, 40, 50, or 80 gallons. Larger homes or those with more bathrooms may need a 50-gallon or larger model. Energy efficiency is another key factor, as more efficient heaters can save on utility bills in the long run.

Consult with plumbers and research professional reviews to determine which type of gas water heater works best for your specific needs. The right choice will provide years of hot water on demand.

Gas Water Heater Basics

Gas water heaters are the unsung heroes of many households, silently providing hot water for showers, laundry, and dishwashing. Understanding how they work can help you appreciate their efficiency and reliability.

At their core, gas water heaters use a gas burner to heat water stored in a tank. When you turn on a hot water tap, cold water enters the tank, displacing the hot water and causing it to rise to the top. The gas burner ignites to maintain the water temperature within the tank, ensuring you have a constant supply of hot water on demand.

One of the key advantages of gas water heaters is their rapid heating capabilities. Unlike electric heaters, which may take some time to warm up, gas heaters provide hot water almost instantly. This quick response time is particularly valuable in busy households where multiple hot water demands can occur simultaneously.

Gas water heaters are also energy-efficient, as they only use energy when heating water, reducing standby energy losses. In addition, they tend to have a longer lifespan compared to electric heaters, making them a cost-effective choice in the long run.

In Sydney’s climate, where cold winters and fluctuating temperatures are common, gas water heaters are a practical choice. They can efficiently provide hot water even when the incoming water is quite cold, ensuring your family’s comfort year-round.

Gas vs. Electric Water Heaters

When choosing between gas and electric water heaters for your home, several factors come into play.


They heat water faster and are generally less expensive to operate than electric heaters. This efficiency is particularly beneficial in Sydney, where the cost of electricity can be relatively high.

Environmental Impact

Gas water heaters are also considered more environmentally friendly than their electric counterparts. They produce fewer greenhouse gas emissions, contributing to a greener and more sustainable home.

Initial Cost

Electric water heaters tend to have a lower upfront cost compared to gas heaters. However, as mentioned earlier, gas heaters are more cost-effective in the long term due to their lower operational expenses.

Size and Space

Gas water heaters typically have a smaller footprint compared to electric ones. This can be advantageous if you have limited space in your utility area.

Availability of Energy Sources

Consider the availability of gas and electricity in your area. In most urban areas of Sydney, both energy sources are readily accessible. However, gas may not be available in some remote or rural locations, making electric heaters the only viable option.

Gas water heaters require regular maintenance, including checking for gas leaks and ensuring proper ventilation. Electric heaters are generally lower maintenance in this regard.


While gas water heaters are safe when correctly installed and maintained, they carry a potential gas leak risk. Electric heaters are considered safer in this regard.

The choice between gas and electric water heaters depends on your specific needs, budget, and environmental considerations.

Tankless vs. Tank-Style Gas Water Heaters

When choosing a gas water heater for your home, you’ll encounter two main options: tankless and tank-style heaters, each with its benefits.

Tankless heaters prioritise energy efficiency, providing hot water on demand to lower energy bills. They offer continuous hot water, save space, and have a longer lifespan.

In contrast, tank-style heaters are budget-friendly upfront, allow simultaneous use, and offer straightforward installation. Your choice depends on usage, space, and budget.

Proper Maintenance for Your Gas Water Heater

Ensuring your gas water heater’s efficient and reliable performance in your Sydney home is crucial. Consider these key maintenance tips:

  • Annual Inspection: Arrange for an annual check-up by a qualified technician to spot potential issues and maintain your heater’s functionality.
  • Flushing: Regularly flush your water heater to remove sediment buildup, prolonging its lifespan and preserving efficient heat transfer.

Tankless Water Heater

  • Temperature Settings: Set your thermostat to around 50 degrees Celsius for safety and energy efficiency, preventing overheating and reducing energy consumption.
  • Check for Leaks: Routinely inspect for gas or water leaks around the unit. If you detect any, promptly turn off the gas supply and seek professional plumbing assistance.
  • Ventilation: Ensure proper ventilation around the water heater to prevent carbon monoxide accumulation, adhering to local safety standards.

Energy Efficient Water Heater

  • Pressure Relief Valve: Annually test the pressure relief valve to ensure it functions correctly by gently lifting the lever to release a small amount of water.
  • Professional Service: If you notice any irregularities or problems with your gas water heater, don’t delay—call a professional plumber for timely repairs to prevent safety hazards and major issues.

Following these maintenance tips guarantees your gas water heater’s efficiency and safety in your home. Regular upkeep extends its lifespan, leading to lower energy bills and a consistent hot water supply.

Energy Efficiency

In pursuing an environmentally conscious and cost-effective solution, the importance of energy-efficient gas water heaters cannot be overstated. These appliances are designed to maximise energy utilisation while minimising waste.

Energy-efficient gas water heaters achieve this through innovative technology. They often feature improved insulation, reducing heat loss from the tank and conserving energy. Additionally, some models use advanced combustion systems, optimising the heating process for increased efficiency.
