Gas VS Electric hot water Systems

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.

What is a gas hot water System?

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.

Types of Gas hot water Systems

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.

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.

Choosing the right water meter

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.

What are the advantages of a gas hot water system over electric?
Gas hot water systems offer several advantages over electric systems: Faster Heating, Cost Efficiency, Continuous Supply, Environmentally Friendly, Reliability, Longevity. Considering these advantages, a gas hot water system can be a reliable, efficient, and cost-effective choice for your hot water needs.
How can I tell if my gas hot water system is malfunctioning?
If you suspect a malfunctioning gas hot water system, watch out for these signs: 1. Insufficient Hot Water: If you’re experiencing a decrease in hot water supply or the water is not getting as hot as it used to, it could indicate a problem with the system. 2. Strange Noises: Unusual noises like banging, popping, or hissing coming from the hot water system may indicate a malfunction. 3. Pilot Light Issues: If the pilot light keeps going out or has a weak flame, it could be a sign of a problem with the gas supply or the ignition system. 4. Leaks or Water Damage: Any signs of water leaks or water damage around the hot water system should be investigated promptly. 5. Gas Smell: If you detect the smell of gas near the hot water system, it’s crucial to turn off the gas supply immediately and seek professional assistance. If you notice any of these signs, it’s important to contact a professional plumber or gas technician to inspect and diagnose the issue. They have the expertise to safely identify and resolve any problems with your gas hot water system.
