What is a solar hot water system, and why are they becoming one of the most popular options for water heating in Australia?

Solar hot water systems utilise the ample free energy given off from the sun to heat water for domestic and commercial purposes. Australia’s sunny weather makes it ideal for utilising solar hot water systems. Most systems involve the installation of a ground-level or rooftop water storage tank and solar collectors installed strategically on a property’s roof.

While solar collectors vary in configuration and technology, the principle behind the various systems remains the same. Cold water is allowed to flow from the tank through the solar collector using a pump or vacuum system. This allows heat to transfer to the water before returning to the tank ready for use within a property. Hot water sitting at the top of a tank, with heavier, cooler water sitting at the bottom-fed through to the solar collectors.

What Are the Benefits of Solar Hot Water Systems?

The installation of a solar hot water system offers 5 distinct benefits:

Reduced energy bills

Heating water for showers, washing and other everyday activities accounts for 15-27% of the average Australian household’s energy bill. Making use of the Sun’s radiation as a free, powerful, and renewable energy resource energy bills can be reduced significantly.

Reduced carbon footprint

Producing hot water is energy-demanding. As such it is the biggest contributor of greenhouse gases to the average Australian home, generating as much as 25% of emissions. By leveraging renewable energy, households can drastically reduce their carbon footprint and help tackle climate change.

Cost-effective

Installation of a solar hot water system is often cheaper than the price of other household power installations. With solar hot water systems recovering their own cost over time, too, they have a distinct advantage over electricity and gas exclusive systems.

Highly efficient

Solar hot water systems are extremely efficient with solar collectors capable of converting 80% of radiation into heat. This can account for as much as 100% of a household’s hot water demand, without the need for gas or electricity.

Low-maintenance

Solar water heaters are not high-maintenance investments. The issue of wear and tear is alien to them as there are no moving parts to tear and break in the first place. Also, solar water heaters typically last longer than the 20-25 years lifespan stated by manufacturers and all they demand in regards to maintenance is regular simple cleaning.

Two Types of Solar Hot Water Systems

There are two main types of solar hot water systems on the market today:

Close-coupled systems

Coupling together a solar collector with a storage tank, close-coupled systems are a single unit that sits on the roof of a property. Water is heated by passing through the solar collector, transferring heat and returning to the storage tank, forcing cooler water towards the collectors.

Using either evacuated tubes or flat plates mounted on the roof of a property, pumped systems use a ground-level tank in conjunction with a pump to force water through the solar collectors. The pump circulates water towards the solar collectors creating a heating loop. Pumped systems are ideal for larger households with roof structures unable to support a large close-coupled system.

Having a Hot Water Systems Booster Installed

Supposing you find yourself in a situation where there isn’t enough sunshine for heating water, you’d need an auxiliary heater to boost the water temperature. Here, the boosters can be either electric or gas. Hot water boosters provide additional support for solar systems during the winter months and when solar gain is diminished. These come in both electric and gas varieties.

Electric-boosted system

A booster element is installed inside the storage tank to heat water when necessary. Energy efficiency can still be maintained by heating water during off-peak tariff hours and using more hot water in the mornings to allow solar gain to be recouped.

Using either natural gas or LPG, gas-boosting units are located externally but nearby to a storage tank to heat water on demand when solar gain is incapable of meeting demand.

Comprehensive Plumbing Services You Can Rely On

Plumbing plays a vital role in the comfort, safety, and functionality of any property. From residential homes to commercial buildings and strata complexes, having a dependable plumbing system ensures water flows efficiently, waste is removed safely, and essential services operate without interruption. When plumbing issues arise, timely and professional attention is critical to prevent damage, disruption, and unnecessary expense.

Our team delivers comprehensive plumbing solutions designed to address both routine maintenance needs and unexpected emergencies. With experience across a wide range of plumbing systems and property types, we focus on delivering practical, long-term outcomes rather than temporary fixes. Every job is approached with attention to detail, clear communication, and a commitment to quality workmanship.


Residential Plumbing Solutions

Homeowners rely on their plumbing systems every day, often without giving them much thought—until something goes wrong. Leaking taps, blocked drains, faulty hot water systems, and burst pipes can quickly disrupt daily life. Professional residential plumbing services help ensure issues are resolved efficiently while protecting the integrity of the property.

Residential plumbing services typically include general repairs, preventative maintenance, installations, and system upgrades. By identifying potential issues early, homeowners can reduce the risk of major failures and extend the lifespan of their plumbing infrastructure. Clear explanations and transparent pricing allow homeowners to make informed decisions about the best solutions for their needs.


Commercial and Strata Plumbing Expertise

Commercial and strata properties require a higher level of planning, coordination, and compliance. Plumbing systems in these environments are often more complex, servicing multiple tenants, units, or facilities simultaneously. Reliable plumbing support is essential to maintain safety standards, minimise downtime, and meet regulatory requirements.

Planned maintenance programs are particularly valuable for commercial and strata clients. Regular inspections, servicing, and reporting help identify issues before they escalate, ensuring systems remain compliant and functional. Clear documentation and communication with property managers and stakeholders are key components of effective commercial plumbing services.


Emergency Plumbing Response

Plumbing emergencies can occur without warning and often require immediate attention. Burst pipes, severe leaks, sewer backups, and loss of essential services can cause significant damage if not addressed quickly. A responsive emergency plumbing service provides peace of mind, knowing help is available when it’s needed most.

Emergency plumbing focuses on rapid assessment, containment, and repair. The priority is to make the situation safe, minimise damage, and restore functionality as efficiently as possible. Once the immediate issue is resolved, further recommendations can be made to prevent recurrence and improve system reliability.


Drainage and Blocked Drain Solutions

Effective drainage is essential for maintaining hygiene and preventing water damage. Blocked or damaged drains can lead to slow water flow, unpleasant odours, and, in severe cases, flooding or structural issues. Professional drainage services use modern equipment and proven techniques to diagnose and resolve these problems accurately.

Drainage solutions may include high-pressure water jetting, camera inspections, repairs, or system upgrades. By identifying the underlying cause of blockages—such as tree roots, debris buildup, or pipe damage—plumbers can implement targeted solutions that restore proper flow and reduce the likelihood of future issues.


Leak Detection and Water Efficiency

Undetected leaks can waste significant amounts of water and cause hidden damage over time. Advanced leak detection methods allow plumbers to locate leaks accurately without unnecessary disruption to walls, floors, or landscaping. Early detection helps protect properties, reduce water bills, and prevent long-term structural problems.

In addition to leak detection, water efficiency improvements can play an important role in reducing consumption and operating costs. Upgrading fixtures, improving system design, and addressing inefficiencies contribute to more sustainable plumbing systems and better overall performance.


Hot Water System Services

A reliable hot water system is essential for comfort and daily routines. Whether a system requires repair, maintenance, or replacement, professional servicing ensures it operates safely and efficiently. Issues such as inconsistent temperatures, unusual noises, or leaks should be addressed promptly to avoid complete system failure.

Hot water services may include repairs, routine servicing, system upgrades, and new installations. Understanding usage requirements and system options allows plumbers to recommend solutions that balance performance, efficiency, and long-term value.


Gas Plumbing and Safety

Gas plumbing requires specialised knowledge and strict adherence to safety standards. Proper installation, maintenance, and testing are essential to ensure systems operate safely and efficiently. Gas-related issues should always be handled by qualified professionals to reduce risk and ensure compliance.

Gas services may include appliance installations, system upgrades, leak detection, and repairs. Regular inspections and maintenance help ensure continued safe operation and provide peace of mind for property owners and occupants.


Commitment to Quality and Professionalism

High-quality plumbing services are built on experience, training, and a commitment to doing the job properly. Clear communication, punctual service, and respect for the property are fundamental aspects of professional plumbing work. By focusing on long-term solutions rather than quick fixes, reliable plumbers help clients avoid recurring issues and unnecessary costs.

Every project, regardless of size, benefits from careful planning and attention to detail. From initial assessment to completion, maintaining high standards ensures consistent results and lasting performance.


A Practical Approach to Plumbing Solutions

Plumbing systems are essential to modern living, and maintaining them requires expertise and proactive care. Whether addressing an urgent issue or planning preventative maintenance, professional plumbing services provide the knowledge and support needed to keep systems running smoothly.

By combining technical skill with clear communication and dependable service, plumbing professionals play a vital role in protecting properties, improving efficiency, and supporting everyday comfort. With the right approach, plumbing challenges can be resolved effectively, allowing clients to focus on what matters most.


Preventative Maintenance and Long-Term System Care

One of the most effective ways to avoid unexpected plumbing issues is through preventative maintenance. Regular inspections and servicing allow potential problems to be identified early, often before any visible signs appear. This proactive approach helps reduce the likelihood of emergency repairs, extend the lifespan of plumbing systems, and provide greater certainty around ongoing maintenance costs.

Preventative plumbing maintenance can include checking pipe condition, inspecting joints and fittings, testing water pressure, assessing drainage performance, and reviewing hot water and gas systems. For commercial and strata properties, scheduled maintenance is particularly important to ensure compliance, minimise disruption to occupants, and maintain consistent system performance across multiple units or facilities.


Clear Communication and Informed Decision-Making

Effective plumbing services are not only about technical expertise but also about clear communication. Understanding the cause of an issue, the available options, and the expected outcomes allows property owners and managers to make informed decisions. Clear explanations and transparent recommendations help build trust and ensure solutions align with both immediate needs and long-term goals.

Providing realistic timeframes, outlining potential risks, and explaining preventative measures are all part of a professional service approach. This level of communication is especially valuable when dealing with complex systems or large properties where multiple stakeholders may be involved.


Compliance, Safety, and Industry Standards

Plumbing work must comply with relevant standards and regulations to ensure safety, performance, and legal compliance. Adhering to industry requirements helps protect occupants, prevent hazards, and ensure systems operate as intended. This is particularly critical for gas systems, backflow prevention, and commercial plumbing installations.

Staying informed about current standards and best practices allows plumbing professionals to deliver compliant solutions that stand the test of time. Proper documentation, testing, and certification provide added reassurance and accountability for property owners and managers.


Supporting Property Value and Asset Longevity

Well-maintained plumbing systems contribute directly to the overall value and functionality of a property. Ongoing care and timely repairs help prevent deterioration, reduce the risk of water damage, and support the longevity of building infrastructure. For investment properties, this proactive approach can lead to fewer disruptions, lower long-term costs, and improved tenant satisfaction.

By addressing plumbing concerns promptly and maintaining systems consistently, property owners can protect their assets and avoid the compounding effects of neglected maintenance.


A Reliable Partner for Ongoing Plumbing Needs

Choosing a plumbing provider is about more than resolving individual issues—it’s about establishing a reliable partnership. A consistent service provider who understands the property, its systems, and its history can deliver more effective solutions over time. Familiarity with existing infrastructure allows for quicker diagnosis, more accurate recommendations, and smoother project delivery.

Whether managing a single residence or a large portfolio of properties, having access to dependable plumbing support provides confidence and continuity. With the right expertise and approach, plumbing systems can be maintained efficiently, safely, and with minimal disruption.

Had an ongoing issue with severe water hammer. Three other companies came and looked at it. The first never got under the house and I never heard from them again. The second didn’t like our (overly friendly) dog. The third quoted a ridiculous amount. Lachy from MPJ came out, on time and diagnosed and fixed on the day in a couple of hours. Very professional and friendly. Explained the cause and the solution. Pleasure to deal with him. He also got on great with the dog.

Frequently Asked Questions

MPJ Plumbing provides a conversion service that allows existing electric hot water systems to switch to renewable, solar energy. This process involves the retrofitting and replacement of certain components within your existing configuration and requires an onsite inspection from one of our experts.

We also provide the conversion of gas-powered hot water systems to solar. Our team can both completely replace a gas system or augment it with renewable solar energy. While over-the-phone advice can be given, a visit from an MPJ team member will allow us to best assess the possibilities for your property.

While solar gain will be diminished during the winter months, the solar collectors used in our systems can still provide heated water all year round. During an Australian summer, you can expect solar hot water systems to be capable of meeting as much as 100% of your property’s hot water demand, with a minimum of 25% met during colder, less sunny periods of the year.

Installation costs range between $4000-$8000 and can vary depending on a property’s existing setup and household demand. Larger households will need a bigger storage tank, for example, with potentially more solar collectors whereas smaller properties with fewer occupants will be able to make use of smaller, less costly systems. In either case, solar hot water systems tend to recoup their own cost over the course of 6-10 years in terms of energy bill savings. With an expected lifespan of at least 20-25 years, this translates into potentially 15 years or more of free energy.
