If you’re just looking at the bills each month, gas is definitely the cheaper option in terms of running cost. While the installation of a gas hot water system costs more than installing an electric system, based on the savings you’ll make you can typically get that extra money back in a year or two of use.

Also unlike electricity there are no time-of-day tariffs for using gas, meaning that it’ll cost you the same no matter when you want to take that shower or run the bath.


A gas hot water system uses either reticulated/piped natural gas or Liquefied Petroleum Gas (LPG) to heat water.

As mentioned a previously gas water heater is usually more expensive to buy and install than an electric hot water system, but it is generally cheaper to use. Another factor to consider is that a gas hot water heater also produces less greenhouse gas emissions than an electric hot water heater.






Continuous Flow Hot Water Systems

The most commonly preferred type of gas water heater is the continuous flow hot water system (also known as 'tankless', 'instantaneous' and 'on-demand' hot water systems). These are small wall-mounted units that heat water as you use it, rather than heating it slowly and storing it as a hot water storage tank does.

Gas Storage Hot Water Systems

Storage gas hot water systems use a gas burner located underneath the storage tank to heat the water. They usually have a continuously burning pilot flame that ignites the main burner when it is needed. Heat is then transferred from the gas burner through the bottom of the cylinder. Some heat also flows from the hot flue pipe into the water. When hot water is drawn off at the top of the tank, cold water enters the tank at the bottom.

Solar Hot Water Systems

Solar hot water systems consist of solar collector panels and a storage tank. As solar water heating is often not sufficiently powerful to deliver all the thermal heat necessary for a hot water heater in a standard Australian family sized home, a gas connected booster is used to ensure the water is always at the right temperature. A well-chosen solar hot water system may cost more to begin with, but for most homes they'll be significantly cheaper to run than a conventional electric or gas system.



Heating method, system type, size, cost and energy efficiency are the five main criteria to consider when purchasing a gas hot water system Each of these factors has an impact on energy use and utility cost. The better you understand each one, the easier it is to compare different models.

Heating Method

Most gas hot water systems use a storage tank, while others heat water “instantaneously” as water passes through the heater and out to the tap or shower. Between the two, continuous flow hot water systems provide hot water on demand in every sense. But the disadvantage is it will generally provide a lower water pressure, so it’s not always the best option for homes that will be using more than a few bathrooms at once.


Getting the right sized hot water system for your home is critical. The perfect size will mean rarely running out of hot water, never wasting money heating water you don't use, as well as potentially saving on the purchase price of your new system. Many factors need to be considered to ensure the water heater you choose is ideal for your home, family and lifestyle.


The first thing to consider is maintenance and the ongoing costs for each type of hot water system. For example, hot water heaters with storage tanks that are not heavily insulated waste energy because of standby heat loss, making it more expensive to run annually. Having a hot water heating and plumbing professional to guide you with the purchase of your new gas hot water heater can make all the difference. After all it’s a decision you’ll be living with for along time and it’s important you make the right one.

Energy Efficiency

Always check how energy efficient a hot water system is to maximise savings on cost and power consumption. Each model has different energy ratings based on recovery efficiency, standby losses, and cycling losses.

    Toilet flusher broke on me this morning. Communication with this company was great! Nick reached out to me first with a rough timeframe when someone would be around (same day). That someone was Gary, who first called asking for more details and I was I was able to provide photos. He gave me a more specific timeframe for his arrival, which he stuck to, and then he showed up with all the parts and tools he needed on hand, knowing exactly what needed to be done, no surprises. He was fast, professional, friendly, and cleaned up everything when he finished. Highly recommended! Cheers Gary!

    We called Pinnacle Plumbing when we discovered a very serious water leak at our house, and we happily recommend them to anyone in Brunswick East and the surrounding suburbs. Despite contacting them after hours, Jay arrived within half an hour of my call and was able to quickly identify the problem, prevent it from becoming a total disaster, and tell me what needed to be done. Jay and Gary were back at 7am the next day, and within a few hours they had found the source of the leak (which was hidden underneath concrete slabs) and fixed it. They also tidied everything up beautifully. They are both lovely, and we will definitely use Pinnacle for any future problems and will recommend them to our friends. Thank you Jay and Gary!
