Installation of an electric hot water system compatible with rooftop solar panels
When a Parramatta homeowner’s rooftop solar hot water system started leaking, they contacted us for assistance. Once onsite at the property, our technicians could see that the leak had likely been occurring for some time but only became noticeable in the cooler months when the family began taking longer showers and, due to the leak, began running out of hot water.
Why you’re likely to run out of hot water if your water heater is leaking
A leaking hot water system can quickly lead to running out of hot water because the tank can no longer stay full, reducing the amount of water available to heat. As water escapes, the system continuously refills with cold water, preventing it from reaching the right temperature. In some cases, the water level drops below the heating element, causing it to overheat or fail. Leaks can also affect pressure and efficiency, disrupting the heating cycle. The result is inconsistent or insufficient hot water, which is often one of the first signs that the system’s internal tank may be corroding or nearing the end of its life.
Finding the best replacement option
During our assessment, the homeowner explained that both they and their neighbour (living in the adjoining duplex) were preparing to have rooftop solar panels installed. With that in mind, we explored several replacement options that would balance energy efficiency, practicality, and cost-effectiveness:
- Install a new rooftop solar hot water system, leaving space for solar panels.
- Replace the old setup with solar collectors and a ground-mounted tank.
- Switch to a modern electric hot water system that could later be powered by their rooftop PV solar panels.
After discussing the pros and cons of each option, the customer chose to install a high-efficiency electric storage system — a simpler, lower-maintenance solution that would easily integrate with their planned solar power system.
Heating hot water with rooftop solar panels
By switching from a rooftop solar system to a solar-compatible electric water heater, the homeowner now enjoys a reliable, ground-level installation that’s easy to maintain and ready to run on free solar electricity once the panels are fitted.
This type of setup offers flexibility and long-term savings. Instead of being dependent on roof-mounted tanks or collectors, the homeowner can still enjoy the benefits of solar energy — but without the extra weight, maintenance, or complexity of a rooftop system.
Another advantage is improved access. Future servicing and replacements can now be performed safely and quickly from the ground, without the need for ladders or roof work.
