However, advancements in technology mean that even homes with east or west-facing roofs can benefit from a SHWS. A site assessment by a certified solar hot water plumber can determine your home’s suitability.
The size of the SHWS you need depends on your household’s hot water demand, which is typically influenced by the number of occupants and your water usage habits. In Australia, the Clean Energy Council suggests a tank size of 100-300 liters for a small (1-2 people) household and a 300-360 liters tank for a larger (3-5 people) household.
While SHWS are more effective on sunny days, they can also provide hot water during winter or overcast days. Most systems have a booster (electric or gas) to ensure a hot water supply during these periods. According to the Australian Bureau of Statistics, a well-chosen and correctly installed SHWS can meet up to 90% of your hot water needs over the year.
Like any other appliance, SHWS needs routine maintenance to ensure optimal operation and longevity. This includes regular system checks, professional servicing every 3-5 years, cleaning the solar collectors, checking the pressure relief valve, and flushing the system periodically. More details can be found in our blog post: “A Guide to Regular Maintenance of Your Solar Hot Water System“.
Yes, the Australian government offers incentives for installing renewable energy systems, including SHWS. The Small-scale Renewable Energy Scheme (SRES) offers Small-scale Technology Certificates (STCs) that can be exchanged for a cash rebate when installing an eligible SHWS.
The lifespan of a Solar Hot Water System varies based on factors such as the quality of the system, installation, usage, and maintenance. On average, you can expect a SHWS to last between 15 to 20 years, potentially longer with proper maintenance and care. Solar collectors often have a longer lifespan than storage tanks.

If you’re a homeowner in Sydney who’s invested in a Solar Hot Water System (SHWS), you’ve made a smart move towards energy efficiency and cost savings. However, like any system, a SHWS may experience issues over time. As a leading solar hot water plumber in Sydney, I’m here to help you troubleshoot common problems that you might encounter with your SHWS.
If your SHWS is not producing enough hot water, several factors could be at play:
A leak in your SHWS could be from the storage tank, the solar collectors, or the connecting pipes. Leaks should be addressed immediately to prevent further damage. An experienced plumber can pinpoint and repair the source of the leak.
If your system’s pump or pipes are making unusual noises, there could be air in the system or the pump may be failing. A professional plumber can purge the system of air or assess the pump for replacement if necessary.
On extremely sunny days, your SHWS could overheat. Modern systems have temperature and pressure relief valves to prevent this. If your system frequently overheats, it could mean these components are not functioning correctly and need to be checked.
If cold water comes out when you turn on the hot tap, it’s possible that the system’s backup heating (electric or gas booster) is not working. A qualified plumber can diagnose and fix this issue.
Solar hot water systems in colder climates may be at risk of freezing, especially if the system is a direct (open-loop) system where water circulates through the collectors. Freezing can cause significant damage, and it’s important to contact a professional plumber immediately if this occurs. To prevent freezing, consider using a system with freeze protection or an indirect (closed-loop) system that uses a heat-transfer fluid.
If your system seems to be less efficient than when it was new, it could be due to scale build-up, particularly in hard water areas. This scale can reduce the efficiency of heat transfer. A professional plumber can clean your system and may suggest a water-softening solution if hard water is an issue.
Extreme weather conditions, falling debris, or general wear and tear could cause your solar collectors to become damaged or cracked. Damaged collectors won’t efficiently absorb the sun’s heat, reducing your system’s effectiveness. Regular visual checks can help you spot any damage early. If you find any issues, call in a professional to assess the damage and carry out necessary repairs or replacements.
A malfunctioning temperature and pressure relief valve (TPR valve) could cause your system to overheat or not heat sufficiently. If you notice water leaking from the TPR valve or unusually high or low water temperatures, it’s time to call in a professional for a checkup.
Over time, your storage tank in a solar heating setup may corrode due to continual exposure to water and heat, particularly if an anode rod is not present or needs replacement.

As we grapple with the realities of climate change, the drive towards achieving net-zero emissions becomes increasingly important. Every sector, every technology, and every one of us has a role to play in this vital mission. As a solar hot water plumber in Sydney, I’ve observed first-hand how Solar Hot Water Systems (SHWS) contribute towards this goal.
Net-zero emissions, also known as carbon neutrality, is achieved when the amount of greenhouse gases produced equals the amount removed from the atmosphere. This balance is crucial in limiting global warming and reducing the impacts of climate change.
Traditional hot water systems powered by gas or electricity contribute significantly to household emissions. In Australia, water heating accounts for around 25% of household energy use, and a substantial part of this comes from non-renewable sources.
SHWS, on the other hand, harnesses the sun’s energy – a renewable, abundant, and free resource. They reduce our reliance on fossil fuels, thereby lowering greenhouse gas emissions.
A 2018 report by the Clean Energy Council stated that replacing an electric hot water system with a solar system can reduce a household’s energy consumption, costs, and greenhouse gas emissions by over 75%.
Let’s consider an average Sydney home with a conventional electric hot water system. According to the Australian Government’s Energy Rating Calculator, this system can produce around 3 tonnes of CO2 per year. By switching to a SHWS with the guidance of a Solar Water Heater Contractor Sydney, this figure could be slashed by more than 75%, saving over 2 tonnes of CO2 emissions annually from one household alone. Now multiply that by thousands of homes across Sydney, and the emissions savings are truly significant.
Apart from the emissions reduction, SHWS also offer energy security and resilience. With the energy being sourced from the sun, households are less vulnerable to energy price fluctuations. The systems also promote local job creation, contributing to a green economy.
Moreover, solar hot water is not just a residential solution. It’s also ideal for commercial applications such as hotels, laundries, and any business that requires significant hot water, further amplifying the potential emissions reduction.
Achieving net-zero emissions is a collective effort, and the transition to renewable energy sources like solar hot water systems is a crucial part of the puzzle. As a solar hot water plumber, I’ve seen the benefits of these systems, not just for individual households, but for our environment and our future.
While the journey to net zero is complex and requires systemic change across all sectors, every switch to a cleaner, renewable technology is a step in the right direction. And in this mission, Solar Hot Water Systems certainly shine bright.
As a solar hot water plumber servicing the Sydney area, I frequently encounter questions from homeowners about how Solar Hot Water Systems (SHWS) actually work. If you’re considering making the switch to a SHWS or if you’re just curious about this technology, this simple explanation is for you.
The fundamental concept behind SHWS is quite straightforward – the sun’s energy is harnessed to heat water. This process is not only eco-friendly but also incredibly efficient and can result in significant energy savings for homeowners. Now, let’s dig into the more specific components and how they operate.
A critical component of any SHWS is the solar collector. These collectors absorb the sun’s heat and transfer it to the water. There are two primary types of solar collectors used in SHWS: flat plate collectors and evacuated tube collectors.
Flat plate collectors, as the name suggests, are flat, darkened panels that absorb the sun’s heat. Evacuated tube collectors are a series of parallel tubes, each containing a heat-absorbent plate. They are generally more efficient, particularly in colder climates, but also tend to be more expensive.
Once the solar collector has absorbed the sun’s heat, this energy needs to be transferred to the water. This process depends on whether you have a direct (or open-loop) system or an indirect (or closed-loop) system.
In a direct system, the water circulates through the solar collectors, gets heated, and then moves into the storage tank.
In an indirect system, a heat transfer fluid (which resists freezing) circulates through the collectors. As this fluid gets heated, it moves through a heat exchanger, which transfers the heat to the water in the storage tank.
The storage tank stores the heated water until it’s needed. Most tanks have an additional heating element (electric or gas-powered), which acts as a backup for times when the solar energy isn’t sufficient to meet the hot water demand.
Controllers and pumps are the ‘intelligent’ components of a SHWS. The controller detects temperature differences between the water in the solar collector and the storage tank. When the collector’s temperature is higher, the controller activates a pump to circulate water or heat-transfer fluid, depending on your system type.
The efficiency of a SHWS depends on several factors including the system type, the quality of the solar collectors, and even the orientation and tilt of the collectors. It’s crucial to work with an experienced solar hot water plumber to design and install a system that maximises efficiency for your specific home.
Understanding how Solar Hot Water Systems work is the first step towards appreciating the sophistication and benefits of this Green Plumbing Technology. By harnessing the abundant energy of the sun, SHWS offers homeowners a reliable, eco-friendly, and cost-effective solution for their hot water needs.
