Gas vs Electric vs Solar: Best Hot Water System for Cairns Homes
When considering your Cairns hot water replacement, the right system is crucial for comfort, efficiency and long term savings. The three main options being gas, electric and solar each come with their own advantages and disadvantages.
Gas systems are known for their reliability and quick heating, while electric hot water systems are often more affordable upfront. On the other hand, having solar hot water in Cairns may offer significant energy savings and environmental benefits but need a higher initial investment.
Making an informed choice ensures your home stays comfortable while reducing your energy bills and carbon footprint. Alfa provides this easy guide to help you choose the right hot water system.

Understanding Your Hot Water Options in Cairns
Within the three primary choices for your Cairns hot water upgrade, there are three primary options to consider, each with its own unique benefits.
Gas Storage or Instantaneous Systems
Reliable and quick heating, even in cloudy weather, but requires access to bottled or natural gas supply to be cost effective. Bottled gas is also an option, but can be less efficient. Having a quicker recovery time than electric makes them an efficient option, especially for families.
Electric Storage or Heat Pump Systems
Affordable upfront but may have higher running costs depending on the available tariffs on offer. They don’t require a gas supply, making them more versatile in terms of installation.
However, they may not be able to provide hot water as quickly as gas models due to slower heating times. Heat pump hot water in Cairns is far more efficient than traditional storage hot water, but has higher set up cost.
Solar Electric Systems
High upfront cost but offer long term savings on energy bills using the sun’s energy to heat up your water supply. Solar systems will need electricity backup for cloudy periods.

Gas Hot Water Systems: Pros, Cons and Best Uses
Pros
- Lower running costs – Natural gas is often cheaper than electricity, offering energy efficient hot water in QLD.
- Fast heating & constant supply – Gas systems heat water much faster than electric and provide a constant supply.
- Reliable – Unlike solar, gas systems work well regardless of the weather, ensuring consistent hot water.
- Longevity – Well maintained gas heaters can last over 20 years, often longer than other types.
Cons
- Higher Cost – Gas systems, especially instantaneous ones, often cost more to buy and install than electric units.
- Gas Supply – Available natural gas connection is far more cost effective than LPG storage.
- Installation – Requires a licensed gas fitter, new gas lines and proper ventilation, potentially increasing costs.
- Environment – Natural gas emits greenhouse gases, making it less eco friendly than solar or heat pumps.
Best fit
Generally, gas storage hot water systems are suited to large families. Whereas instantaneous systems are great for smaller properties and units, but the final decision depends on a range of factors. Alfa’s licensed gas fitter will fully assess and advise the best system for you!

Electric and Solar Hot Water: What Suits Cairns Climate?
When choosing between either electric or solar hot water systems for the tropics, here’s a simple comparison.
Electric
Electric hot water systems are suitable for all weather conditions and provide a reliable supply, though this convenience may lead to higher energy costs during peak usage. However, newer models for electric hot water have been specifically designed to achieve maximum efficiency, especially in our climate.
Also considering modern electric heat pump efficiency for tropical weather can be highly efficient and comparable in performance to both traditional storage systems and solar options.
Solar
Solar hot water systems are ideal for Cairns, thanks to the region’s abundant sunshine, making it a very environmentally friendly option. They will require an electricity backup during the wet season when continually cloudy and typically have higher upfront installation costs.
Fortunately, these solar installation costs are generally recovered over time because you will be generating your own electricity. Alfa Plumbing can discuss all these factors with you to find the best and most cost effective option for your household’s needs.

Key Factors to Decide: Cost, Efficiency and Household Needs
When thinking about installing tropical hot water systems and gas vs electric hot water, you’ll need to weigh up a few factors before you decide. Alfa offers a variety of choices and will discuss all available options that suit your own requirements. We understand that your property layout, space available for the hot water equipment and local water pressure all play a part.
Budget is, of course another aspect to consider, as well as the length of time you are intending to stay at your current property. For instance solar hot water is a great option if you have high water pressure and intend to stay at the property for a length of time. This will deliver a high return on investment.
Government Hot Water System Rebates are another factor to keep in mind when selecting your hot water system. The Queensland government offers various rebate programs for energy efficient hot water systems, such as solar or heat pump options. We can assist with either option and provide details on the eligibility requirements and application process for these rebates.
