Are you tired of sky-high energy bills? Worried about your home’s carbon footprint? Or perhaps your aging hot water system is finally giving up the ghost? Replacing your hot water system is a significant decision, impacting both your wallet and the environment.
Hogan Hot Water & Air Conditioning has put together this guide to compare solar and gas hot water systems, analysing their long-term costs to help you make an informed choice. We’ll examine initial investment, ongoing running expenses, maintenance needs and available government rebates in NSW to determine which system offers the best value over its lifespan.
Upfront Costs: Solar Hot Water vs Gas Hot Water System Installation
The initial investment for a new hot water system varies significantly between solar and gas options in NSW. Gas hot water systems typically have a lower upfront cost. A basic storage-type gas system might cost between $1,500 and $2,500 to install, while a continuous-flow system could range from $3,000 to $5,000, depending on size and features.
Solar hot water systems, however, demand a much larger initial investment. A standard system typically starts at $4,000 and can easily reach $8,000 or more. This cost can climb considerably based on factors such as tank size, the type of solar panels used (evacuated tube systems tend to be pricier) and the complexity of the installation. Homes requiring larger systems or those with challenging roof structures will typically face higher expenses. It’s important to note that while the upfront expense for solar is substantially greater, this is often mitigated by government rebates and incentives offered in NSW, which we’ll explore further in this blog.
Comparing Solar & Gas Hot Water Running Expenses in NSW
The ongoing energy costs for solar and gas hot water systems in NSW differ significantly, primarily influenced by gas prices and solar system efficiency. Gas hot water systems’ running costs are directly tied to natural gas prices, which fluctuate. In NSW, these fluctuations can lead to considerable variations in monthly bills. A typical NSW household using a gas system might see monthly bills ranging from $30 to $80 or more, depending on usage patterns and the prevailing gas price at the time.
Solar hot water systems in NSW, while having a higher initial cost, offer the potential for substantial long-term savings. They use a small amount of electricity to power the circulation pump, but their primary energy source – sunlight – is free. This significantly reduces reliance on the electricity grid, leading to lower bills. However, during periods of extended cloud cover or in winter months, the system will draw more power from the grid to supplement solar energy. The level of savings achieved depends largely on the system’s efficiency (determined by panel quality and installation) and the household’s hot water usage.
A highly efficient solar hot water system in NSW could dramatically decrease or even eliminate hot water-related electricity costs over the long term. A less efficient system or one in a household with high hot water demand might see less dramatic savings. It’s crucial to consider these factors when weighing the long-term energy expenses of solar versus gas hot water systems in NSW.
Hot Water System Maintenance: Long-Term Costs & Lifespan Considerations
While both solar and gas hot water systems require maintenance, their needs and associated costs differ. Gas hot water systems typically have a shorter lifespan, often lasting 10-15 years. Regular servicing, including annual inspections and cleaning, is recommended to ensure safe and efficient operation. Potential repairs might include replacing gas burners, thermostats or other components, with costs ranging from a few hundred to several thousand dollars depending on the issue. Neglecting maintenance can lead to premature failure and significantly higher repair costs.
Solar hot water systems generally boast a longer lifespan, often lasting 20 years or more with proper care. Maintenance includes periodic flushing of the tank to remove sediment build-up, which can impact efficiency and longevity. Regular inspection of panels, pumps and sensors is also essential.
Government Rebates for Hot Water Systems in NSW
The NSW Government offers incentives to help lower the cost of upgrading to energy-efficient hot water systems, aiming to reduce energy consumption and emissions. This incentive isn’t a direct rebate, but rather an upfront discount applied to the quote for installing a new, energy-efficient solar or heat pump hot water system. The discount amount varies depending on the type of replacement and the chosen installer, ranging from $190 to $670. Specifically, replacing an electric water heater with an air source heat pump system could offer a discount between $400 and $670, while replacing a gas water heater with a heat pump could yield a discount of $190 to $310.

Total Cost of Ownership: Solar vs Gas Hot Water Over 10 & 20 Years
Over 10 years, a gas hot water system might cost significantly less initially, but the cumulative energy costs could be higher than a solar system, particularly in NSW, where gas prices can fluctuate.
By year 15, and almost certainly by year 20, the lower ongoing energy costs of a solar system, combined with potential government rebates, would likely lead to a lower overall cost. This is largely due to the significantly reduced operational expenses of solar.
While solar systems might require more expensive repairs occasionally, the substantial savings on energy bills typically offset this. Therefore, the return on investment for a solar hot water system materialises over time, making it a more cost-effective option in the long run for most NSW homeowners.
