Types of Hot Water Systems We Work With
There is no single hot water system that suits every home or business. The right choice depends on the size of your property, the number of people living or working there, your energy preferences and your long term running costs. Synergy Trades works with every major hot water brand and system type, and our licensed plumbers provide clear guidance on the most reliable and energy efficient option for your needs.
We repair, replace and install the leading brands including Rheem, Rinnai, Thermann, Vulcan, Aquamax, Dux, Bosch and Solahart. Whether your system has completely failed, is showing early warning signs or simply cannot keep up with daily use, our team can diagnose the issue and help you choose the best solution.
Electric Hot Water Systems
Electric hot water systems are one of the most common choices across the Sunshine Coast because they are reliable, cost effective and suitable for most homes. Popular brands include Rheem, Aquamax, Dux and Thermann.
Common issues with electric units include thermostat faults, burnt-out elements, tripped circuits, pressure relief valve leaks, slow heat-up times and tanks that are rusting from the inside. Older systems can also struggle to maintain a consistent temperature or run out of hot water too quickly due to sediment build up inside the tank.
Synergy Trades provides fast repair services for all electric systems, and if a replacement is required, we supply modern, energy efficient models that heat faster and reduce electricity costs. We can help you choose the right size system for your household, whether it is a 125 litre unit for small homes or a 315 litre system for larger families.
Gas Hot Water Systems
Gas hot water systems are ideal for households that want instant, continuous hot water without relying on electricity prices. They come in both storage tanks and continuous flow models, with top brands including Rinnai, Bosch and Rheem.
Common gas system problems include ignition or pilot light faults, fluctuating temperatures, blocked gas burners, error codes, corroded heat exchangers and systems shutting down unexpectedly. Continuous flow models can also suffer from low water pressure issues if the system is undersized for the home.
If your gas heater is not performing the way it should, we can inspect the unit, clear blockages, replace faulty components or recommend a modern high-efficiency system that provides consistent hot water while keeping energy costs down. Our team also handles full replacements and upgrades for ageing or unsafe gas systems.
Solar Hot Water Systems
Solar hot water systems are a smart and cost saving choice for Sunshine Coast homes, especially with Queensland’s long warm seasons and high solar exposure. Leading solar brands include Solahart, Rinnai, Rheem and Chromagen.
Common solar hot water issues include failed circulation pumps, faulty sensors, cracked or leaking solar collectors, booster element problems, low pressure, airlocks in the lines and systems that struggle on cloudy days when the booster is not switching on correctly. Tanks exposed to coastal conditions may also corrode more quickly.
Synergy Trades repairs, services and replaces all types of solar systems, including roof mounted and split systems. If your solar unit is not heating properly, losing pressure or costing more to run than it should, we can identify the cause and recommend a targeted repair or a full upgrade to a more efficient model.

Fast Hot Water Repairs Sunshine Coast
Hot water problems often happen suddenly and always at the worst time. Our plumbers provide fast, reliable repairs across the Sunshine Coast and aim to restore your hot water as quickly as possible.
We diagnose issues such as leaking tanks, rusty or brown discoloured water, low pressure, temperature problems, faulty valves, failing elements and unusual noises inside the tank. Once we identify the problem, we explain the repair and provide clear pricing so there are no surprises. If a repair is not the best long term option, we offer replacement recommendations that match your home, budget and energy needs.
With our experience, most problems can be fixed on the spot.
Hot Water System Replacement and Installation
When your hot water system is beyond repair, we make the replacement process simple. We complete a full assessment, remove and dispose of your old unit, and install a new system safely and professionally. Every installation includes testing, commissioning, temperature checks and a clear explanation of how to use and maintain your new unit.
We work with all major brands including Rheem, Rinnai, Dux, Vulcan, Thermann, Bosch, Aquamax and Solahart. Whether you need electric, gas or solar, we can recommend the right size and model for your property and provide upfront pricing so you know exactly what to expect.
Preventative Maintenance and System Health Checks
Coastal homes on the Sunshine Coast often experience earlier wear and tear because salt in the air accelerates corrosion. Regular maintenance helps extend the life of your hot water system, improves energy efficiency and reduces the likelihood of unexpected breakdowns.
Warning signs your system may need attention include fluctuating temperatures, water running out too quickly, higher electricity bills, unusual smells or discolouration, and moisture around the base of the tank. A quick health check can identify these issues early and save you money in the long run.

Left unattended, water hammer can lead to an array of major plumbing problems in the future including burst pipes, loose fittings, or damage to fixtures.

- All of the internal cold water taps in the rental property (except those serving a bath) are to deliver a maximum of 9 litres of water per minute;
- All shower heads in the rental property are to have a maximum flow rate of 9 litres per minute; and
- All the toilets in the rental property are to be dual flush, with the maximum flush volume of the full flush to be 6.5 litres, and the maximum for the half flush being 3.5 litres. Additionally, they must have a maximum average flush volume of 4 litres (based on the average of 1 full flush and 4 half flushes).
