When a hot water system fails in Mildura, you usually need a replacement within a day or two. That urgency can push people toward the quickest and most familiar option rather than the right one for their home. This guide gives you the information to make a good decision, even if you need to move fast.
The two main choices for most Mildura homes are natural gas storage and electric storage. Heat pump systems are a third option worth knowing about, particularly if you want lower running costs over time. Below Brad walks through each.
Natural gas hot water systems
If your home is already connected to natural gas, a gas storage system is often the most straightforward replacement. Gas heats water faster than a standard electric element, recovery time after heavy use is shorter, and gas tariffs in regional NSW and Victoria have historically been lower than electricity costs for the same energy output.
The main constraints are that you need an existing gas connection and the system must be installed by a licensed gas fitter, which in most cases is your plumber. Brad is gas licensed and installs gas hot water across Mildura and Dareton.
Best for: Homes already on natural gas, larger households with high hot water demand, and situations where installation simplicity matters because you are replacing a gas unit like for like.
Electric storage hot water systems
Standard electric storage systems are the most common type in Australian homes without gas. They are lower upfront cost to install than gas or heat pump systems, widely available from local suppliers, and simple to maintain. The trade off is higher running costs, since electrical resistance heating is not particularly efficient.
In Mildura's hard water, electric elements are particularly susceptible to scale buildup, which reduces efficiency and shortens element life. If you have an electric storage system, the sacrificial anode (a magnesium or aluminium rod inside the tank that protects it from corrosion) should be replaced every 5 years to extend tank life significantly.
Best for: Homes without gas connections, rental properties, smaller households, and situations where upfront installation cost is the primary constraint.
Heat pump hot water systems
A heat pump is an electric system that works by extracting heat from ambient air rather than generating heat directly from an element. Think of it as the reverse of an air conditioner. The result is a system that uses 60 to 75% less electricity than a standard electric storage unit while still running on your existing electrical connection, with no gas required.
The initial purchase price is higher, typically $2,000 to $3,500 installed, but government rebates (through the Small-scale Renewable Energy Scheme) can offset a significant portion of this. In Mildura's warm climate, heat pumps perform well year round since they extract heat from outside air even in mild conditions.
Best for: Homeowners without gas connections who want lower running costs over the life of the system. Particularly well suited to Mildura's climate. Worth considering if the system you are replacing was 10 or more years old.
Hard water note: Whatever system you choose, scale buildup from Mildura's hard water will affect it over time. Ask Brad about anode replacement schedules and whether a water softener or scale inhibitor at the inlet makes sense for your property.
Side by side comparison
| Factor | Natural gas | Electric storage | Heat pump |
|---|---|---|---|
| Upfront cost (installed) | $1,200 to $2,000 | $900 to $1,500 | $2,000 to $3,500 |
| Running cost (relative) | Low to medium | Higher | Lowest |
| Requires gas connection | Yes | No | No |
| Government rebates | No | No | Yes (SRES) |
| Recovery speed | Fast | Slower | Moderate |
| Typical system life | 10 to 15 years | 8 to 12 years | 10 to 15 years |
What about solar hot water?
Solar hot water systems are worth mentioning, though they are less common in regional areas than in capital cities. They use roof-mounted collectors to heat water directly from sunlight, with an electric or gas booster for overcast days. Mildura's sunshine hours make it a genuinely good location for solar hot water. That said, they require specific roof orientation and adequate roof space, and the installed cost is higher than other options. If you have the right roof and a longer time horizon, it is worth getting a quote for comparison.

📞 Call 0411 755 399Can you switch from gas to electric (or vice versa) in Mildura?
Yes, switching is possible. Moving from gas to electric requires capping the gas supply and installing the new electric unit on a suitable circuit. Moving from electric to gas requires an available gas line nearby. Either way it adds some complexity and cost to the installation compared with a like for like replacement.
If you are switching, it is worth doing the running cost maths before committing. The difference in running costs between a gas system and a heat pump system can amount to several hundred dollars per year, which compounds into a significant saving over a 10 to 12 year system life.
