When your old hot water system finally gives up, you’re faced with one big decision — gas or electric? Each option has its advantages, but the best choice depends on your household size, budget, and access to natural gas.
In suburbs like Brighton, Sandringham, and Beaumaris, both systems are popular — yet many homeowners stick with the wrong one simply because that’s what was already installed.
Let’s break down the differences that actually matter.
1. Upfront Cost vs Long-Term Savings
Electric storage systems are generally cheaper to buy and install. But they use more energy to maintain heat, especially during Bayside’s cooler months.
Gas systems cost more upfront but often recover heat faster and have lower running costs, particularly if you’re on natural gas mains rather than bottled LPG.
| Feature | Gas Hot Water | Electric Hot Water |
|---|---|---|
| Upfront Cost | Medium–High | Low |
| Running Cost | Low (mains gas) | Medium–High |
| Recovery Speed | Fast | Moderate |
| Efficiency | High (continuous flow) | Moderate |
| Ideal For | Large households | Smaller homes / units |
2. Performance and Reliability
Gas systems heat water on demand, so you’ll never “run out.” They’re perfect for families with back-to-back showers.
Electric systems rely on stored hot water — once the tank’s empty, you’ll wait for it to reheat.
However, electric units are simpler, with fewer moving parts, meaning they can be slightly easier and cheaper to service.
3. Environmental Impact
Gas is cleaner than coal-powered electricity but still fossil-based. If your home uses renewable electricity (like solar panels), a high-efficiency electric or heat pump system can actually be the greener choice.

4. Space and Installation
Gas systems need outdoor ventilation and safe flue placement. Electric units, on the other hand, can be installed indoors or outdoors, offering more flexibility — especially in Hampton and Caulfield homes with limited yard space.
Your property layout and access to gas lines will often decide which option makes sense.
5. Common Maintenance and Lifespan
Gas systems:
- Require regular burner and flue checks
- Usually last 10–15 years
- More prone to pilot light or ignition faults
Electric systems:
- Need periodic anode replacement to prevent rust
- Lifespan 8–12 years
- Easier to relocate or upsize
For both, annual servicing is critical to avoid corrosion or heat loss.
6. The Best Choice for Bayside Homes
If you have natural gas access, gas instantaneous systems are typically the most economical and reliable option.
If you don’t, consider electric storage or heat pump units paired with off-peak tariffs or solar — they’ll save energy without sacrificing comfort.
