You turn on the shower, wait for the water to warm up and suddenly realise something isn’t quite right. Maybe the hot water runs out too quickly, your energy bills have increased, or your old system is simply reaching the end of its life.
If you’re replacing a hot water system, one of the first decisions you’ll face is whether to choose gas or electric. Both can work well, but the better option depends on your home, energy setup, hot water needs and budget.
How Does an Electric Hot Water System Work?
An Electric hot water system uses electricity to heat water stored in a tank or, in some configurations, heat water as it is needed.
Electric systems are widely used because they can suit homes without a gas connection. They can also be paired with solar electricity, which may help reduce reliance on grid electricity depending on your setup.
The main consideration is running cost. Electricity prices, household usage and the system’s efficiency can all affect how much it costs to heat your water.
When Does Gas Hot Water Make Sense?
Gas systems use natural gas or LPG to heat water. They can be a suitable option for homes that already have a gas connection and prefer gas-powered appliances.
A gas system can provide strong heating performance, but installation requirements are different from electric systems. Ventilation, gas connections and applicable safety requirements all need to be considered.
If you’re switching from electric to gas, professional Gas hot water installation is important because gas appliances need to be installed safely and in accordance with relevant requirements.
Which System Is More Affordable to Run?
There isn’t one answer for every household.
Running costs depend on factors such as energy prices, household size, water usage and the efficiency of the system. A system that looks cheaper to operate in one home may not provide the same savings in another.
It’s worth comparing both the purchase price and ongoing energy costs rather than focusing only on the initial installation.
What Should You Consider Before Choosing?
Start with your household’s actual hot water needs.
A couple living in a small home may have very different requirements from a family with several bathrooms. Consider how many people use hot water, when they typically use it and whether your current system struggles to keep up.
Your available energy connections matter too. If your property doesn’t have gas connected, installing a gas system may involve additional work and costs.
Does Installation Quality Matter?
Absolutely. Even a high-quality system won’t perform as expected if it’s incorrectly installed.
Professional Hot water system installation ensures the system is properly connected, configured and tested. It can also help identify whether your chosen system is appropriate for your property’s existing plumbing and energy setup.
Before installation, ask about system sizing, warranty requirements, ongoing maintenance and what is included in the quoted price.
When Should You Replace Your Hot Water System?
Frequent breakdowns, inconsistent water temperature, unusual noises, leaks, or an ageing system can all be signs that it’s time to investigate replacement options.
You don’t necessarily need to wait for a complete failure. Planning gives you more time to compare systems and choose an option that suits your household.

So, Which Hot Water System Should You Choose?
Gas and electric systems both have advantages. The right choice comes down to your home’s energy connections, hot water demand, installation requirements and long-term costs.
Rather than choosing based solely on what worked in your previous home, consider how your household actually uses hot water today.
