Research has shown that water heating is the second largest contributor to the average Australian energy bill. Depending on your location, this can range anywhere from 15% to 27%. With this in mind, it’s no wonder that many locals are looking for more active ways to reduce these costs and make their homes more sustainable.
Fortunately, installing a solar water heater system isn’t as complex as you may think. An expert plumber Melbourne residents use for all their plumbing needs will have your system installed in no time. If you’re toying with the idea of switching your traditional water heater system with its modern solar counterpart, then this post is a must-read.
How do Solar Hot Water Systems Work?
Essentially, solar hot water systems work by using efficient roof-mounted collectors that absorb energy from the sun’s UV rays. This energy is then transferred to the water tank which can be stored on the roof or the ground.
It’s not uncommon for people to wonder if solar systems can provide heat at night when the sun’s down. The good news is that you will always have hot water with a properly installed system. During the day the solar panels heat the water that’s stored in an insulated tank, which keeps the water warm.
You can also request your plumber to add an electric or gas booster to provide additional hot water if it’s required. Some models that have the booster feature also have a manual override switch to switch this off if it’s not needed.
Many Positives to Keep in Mind
Installing a solar water heater has many advantages. Our plumbing team has compiled a list of the top reasons that every Australian household should make the switch from regular water heating systems to the more renewable solar option.
1. Drastic Reduction in Your Energy Bill
Current surveys are showing that a household that uses a solar water heater in Australia can save between 60% and 75% on energy costs. This varies depending on the amount of sun in your area as well as your average household usage.
No matter where in Australia you’re living, investing in a water solar heating system will allow you to save a considerable amount of money. Solar panels typically convert up to 80% of radiation to heat energy without the need for any external fuels.
2. Require Less Space
Traditional water heaters can be bulky and often require significant space somewhere in or outside your home or roof. Solar water heaters, on the other hand, take up less space. This is because the tanks can be placed on the roof or the ground, making these units ideal for smaller homes. Your plumber will decide between PV and thermal panels to accommodate the space you have available.

3. Low Maintenance
Another huge plus point is that solar water heaters require very little maintenance. This is because this system doesn’t have any moving parts so there are no loose components that need to be maintained or replaced.
Your system may require simple cleaning which involves checking the panels for debris such as dust and pollen. Quality solar hot water systems only need professional servicing every five years and usually have a lifespan of about 20 years. The plumber installing the unit will advise you on the best ways to do this, depending on the type of system you have.
4. Reduce Your Carbon Footprint
If you’re already using solar panels as part of your home’s individual renewable energy goal, then it makes sense that converting your water system is the next logical step to follow.
Solar energy reduces the need for harmful chemicals and electricity which instantly reduces your home’s carbon footprint. This eco-friendly solution also reduces your need for electricity from the main grid.
On average, greenhouse gas emissions stemming from electric hot water systems can equate to about 28-30 Tco2e over 10 years. Switching to a solar water heater will eliminate this from your household.
5. Potential Government Rebates
Depending on where you live, you may be eligible for a rebate from the Australian government for installing a solar water heater. It’s essential to check with the plumber doing the initial installation whether or not your area and household will qualify for this. Any rebates will help to reduce the costs of the initial installation costs, making it easier for many households to make the switch.

6. Sizes Vary
As with gas and electric water heaters, the solar option can be purchased in a size that suits your home’s needs. Giving your installer an accurate outline of the home’s water requirements will make it easy to choose the right tank capacity and type of water collector.
Final Thoughts
While it’s true that your solar water heater may require an initial investment, you’ll easily be able to offset this against the savings you’ll be seeing on your energy bill. Not only is this system low maintenance, but it will also provide you with hot water when you need it without adding to the strain on the environment!
