Hot water systems are built to last however when the time comes to replace or repair your system, The Clean Plumber team are on hand ready to undertake all your electric or gas hot water needs.
If you’re lucky enough to be able to have your system repaired instead of having to install a complete new one, we have all the tools and equipment available in our service trucks so you can be assured that you’re not waiting around for us to get parts and spend unnecessary time on the job.
If you require a new hot water system, our trained technicians can guide you through the process of which system would be best for your home and provide recommendations on the benefits of different brands at different price points. We don’t work exclusively with one brand of hot water systems so you can be assured that we will tailor our advice to your needs.
Solar Hot Water System Installation
With The Clean Plumber, switching to solar hot water from an existing electric or gas system is simple. Our team will evaluate your household’s hot water needs and recommend a system that ensures immediate reliability and long-term efficiency.
Solar hot water systems offer significant environmental and cost-saving benefits. By harnessing the sun’s energy, you’ll reduce your reliance on traditional power sources, reducing your electricity or gas bills while lowering your carbon footprint. On overcast days, when sunlight is limited, solar water heaters include electric or gas boosters to ensure a consistent hot water supply.
Switching to solar hot water is an investment in your home and the environment. Let The Clean Plumber guide you through the process and help you choose the best system for your household’s needs.

I had a fantastic experience with Clean Plumbing in Kellyville. Thanks Kevin, from the first call to the completed job, their service was professional, prompt, and stress-free. The plumber arrived on time, clearly explained the issue, and fixed it efficiently with no mess left behind. Pricing was fair and transparent, which I really appreciated. It’s refreshing to deal with a local business that genuinely cares about quality and customer satisfaction. Highly recommend Clean Plumbing to anyone in Kellyville looking for reliable, honest plumbing services!
Job was done efficiently and quickly and Isaac showed me on the camera that the sewer line was now clear of any obstructions. Polite and efficient will definitely use again.

FAQs
Most hot water systems last 8 to 12 years. Regular maintenance services such as anode checks and thermostat testing can extend the lifespan. Units that are serviced properly tend to run more efficiently and last longer.
Costs vary by size and type. Small electric hot water systems can start from around $900 fully installed, while larger gas hot water systems or instantaneous water heaters may range from $1,600 to $2,500. We always provide upfront pricing with no hidden extras.
Yes. You can switch from an electric hot water system to a gas hot water heater or move to an instantaneous system if you want energy efficiency and endless hot water. Our licensed hot water plumbers can handle the full installation process safely.
Yes. All hot water system installations in Sydney must be done by licensed plumbers. Professional fitting keeps your water heater safe, compliant, and covered under warranty. DIY installs can create risks and void manufacturer guarantees.
Most hot water system installs take 2 to 4 hours. Same-day service is available if your system has failed and you need hot water quickly. Larger hot water tanks or switching from one system to the other may take longer, but we’ll confirm timing upfront.
Storage systems need servicing every 3 to 5 years to check anodes, flush sediment, and test thermostats. Gas and electric hot water systems both benefit from regular checks, while instantaneous water heaters should be inspected to maintain efficiency.
Sediment buildup inside the hot water tank is usually the reason behind the noise. Flushing and maintenance prevent this issue. If the sound persists, our team can inspect and repair the system to stop further damage.
Low pressure may be caused by a valve issue, sediment in the tank, or if your hot water system is not aligned with your household needs. Our plumbers can test your supply, identify the cause, and restore proper flow.
