Choosing a hot water system is not just about ticking a box. It is something that affects your day-to-day comfort, your bills, and even your household routines. At Horncastle Plumbing, we have worked in homes across Adelaide for years, and one question always comes up: Should I go with gas or electric?
There is no one right answer, but we can help you think it through.
The Real Difference Starts with How You Use Hot Water
Every household runs differently. Some people have long showers. Some have dishwashers and washing machines running at the same time. If you are in a smaller home, or if you live alone or with just one other person, your needs will be different than a busy family with teenagers.
Gas systems are great if you need a lot of hot water quickly. Continuous flow models only heat water when you need it, so you are not paying to keep a tank hot all day. That can make a big difference, especially if you use hot water at different times of the day.
Electric systems often use storage tanks. Once the hot water runs out, it takes time to reheat. That might be fine if you are not using much at once. But if the shower goes cold mid-way through, you will notice.
What About the Upfront Cost?
Electric hot water systems usually cost less to buy and install. They are simple to set up and do not need a gas connection. That makes them a good option if you want to get up and running quickly or if your property does not have gas already connected.
Gas systems often cost more upfront. The units themselves can be a bit pricier, and if we need to extend or install new gas lines, that adds to the job. But once installed, gas units tend to pay off in the long term with cheaper running costs.
Day-to-Day Running Costs Matter
Electricity rates in Adelaide have gone up over the years, and that has pushed many homeowners to look for lower-cost solutions. Natural gas, while not perfect, has remained more stable in pricing.
If you are using a lot of hot water, a gas system will usually cost less to run month-to-month. It heats faster, uses less energy to get the job done, and the continuous flow models avoid waste.
But electric systems can still be efficient, especially if you are on solar. If your panels generate enough power during the day, you could be heating water with very little cost at all.
Adelaide Hot Water Repairs, Lifespan, and Maintenance
Gas systems can last a long time, particularly the continuous flow types. They are designed for regular use and stand up well over time, but they do need servicing now and then to stay safe and efficient.
Electric systems are simpler and can be easier to repair, but the tank is usually the weak point. If the cylinder starts to rust or split, it is often better to replace the unit altogether. Regular maintenance helps either way, and that is where a local plumber you trust makes all the difference.
What About the Environment?
If you care about reducing emissions, this might help you decide.
Gas produces fewer emissions during use, but is still a fossil fuel. Electric systems powered by standard grid electricity often have a higher carbon footprint, but if your power comes from solar, they can be the cleaner choice overall.
So… What’s the Verdict?
If your home already has gas, and you use a lot of hot water, a gas system and that too a continuous flow model, can save you money and work better with your daily routine.
If your home runs on electricity, or if you have solar panels installed, an electric system might make more sense, especially if your usage is lower.
