Our Hot Water System Services
Hot Water System Installation
Installing a new hot water system is an investment in comfort and energy efficiency. We help you choose the right system for your home size, budget, and usage patterns.
We install:
Electric Hot Water Systems — Reliable and cost-effective
Gas Hot Water Systems — Fast heating with lower running costs. Typically only installed when Natural Gas is available.
Instantaneous / Tankless Systems — Unlimited hot water on demand. Available in both electric and gas.
Solar Hot Water Systems — Eco-friendly and energy efficient.
Heat Pump Systems — High efficiency with low running costs.
Hot Water System Repairs
Hot water systems can fail due to leaks, pilot light issues, thermostat and element faults, sediment buildup, valve problems, or age-related wear. We diagnose and fix issues quickly to minimise downtime.
Common repair problems we fix:
Inconsistent or No Hot Water — The system is no longer heating effectively.
Poor and Inconsistent Water Pressures — Often caused by sediment build-up, blockages to internal valves or poor water quality.
Strange Noises — Usually knocking or banging noises suggest there are damaged parts. Hissing noises usually suggest leaks or faulty valves.
Leaks and Corrosion — Leaking valves can be repaired or replaced. Leaking cylinders requires a replacement as cylinders have rusted out.
Discoloured Water — A clear indicator of tank corrosion or bad quality water.
Hot Water System Replacement
Is your hot water system old, inefficient, or constantly failing? We’ll help you assess whether repair or replacement is the most cost-effective choice. New systems can save you money on energy bills, continuous repairs and helps reduce headaches from repeated breakdowns.
Maintenance & Servicing
Did you know regular servicing extends the life of your hot water system and keeps it running at peak performance? We recommend annual checks to remove sediment, test safety valves, inspect heating elements or burners, and optimise performance. Most storage hot water systems contain a sacrificial anode internally that when replaced regularly can prolong the life of the cylinder and sediment build up.
Hot Water System Emergencies
A hot water system emergency can strike without warning — cold showers, leaking tanks, gas smells or complete system failure can disrupt your home or business instantly. We provide emergency services to get your hot water restored as quickly and safely as possible. We offer emergency hot water system repairs, emergency hot water system replacements and temporary hot water system hire.

Frequently Asked Hot Water Questions
-
Common signs your hot water system may be failing include inconsistent water temperature, the hot water is running out quickly, it is making unusual noises (banging, rumbling or hissing), it’s leaking around the base of the unit, or producing discoloured/rusty water. Other signs you may notice is the system is tripping the power, taking longer to heat, or producing lukewarm or cold water. If you’re experiencing any of these hot water system issues, it’s best to book a licensed plumber early to prevent a complete breakdown. Good Az Plumbing provides hot water system replacements and repairs in Noosa, diagnosing problems fast and recommending the most cost-effective solution.
-
Most hot water systems last approximately around 8 to 15 years but sometimes as much as 20+ years. This timeframe usually depends on the type of system, the water quality, usage, and how well the unit is maintained. In coastal areas like Noosa and the Sunshine Coast, hot water systems can sometimes wear out sooner due to higher humidity, salt exposure, and corrosion over time.
As a general guide:
Electric storage hot water systems: 8–15 years
Gas storage systems: 8–12 years
Instantaneous (continuous flow) systems: 12–20 years
Heat pump hot water systems: 8–15 years
Solar hot water systems: 10–20 years (components may vary)
Signs your system may be nearing the end of its life include leaks, rusty/discoloured water, temperature fluctuations, unusual noises, or frequent repairs. At Good Az Plumbing, we provide professional hot water system inspections in Noosa and can advise whether a repair is worthwhile or if replacement is the better long-term option.
-
Choosing the right hot water system size for your household depends on the number of people in your home, bathroom count, and water usage patterns (especially morning/evening peak demand). As a general guide:
1–2 people: 80–160L storage / smaller instantaneous
3–4 people: 160–250L storage
5+ people: 250–400L storage or larger continuous flow/instantaneous
If your system is too small, you’ll run out of hot water quickly. If it’s too large, you may pay more in running costs than necessary. Good Az Plumbing can recommend the correct hot water system size in Noosa based on your household and budget.
-
The “best” hot water system depends on your property, budget, energy availability and long-term running costs.
Electric hot water systems are affordable and reliable, ideal for many homes and businesses.
Gas hot water systems heat quickly and can reduce running costs if natural gas is available.
Solar hot water systems are energy-efficient and great for reducing power bills long-term.
Heat pump hot water systems are highly efficient, especially in warm climates like Noosa.
Instantaneous (continuous flow) systems provide hot water on demand and save space.
At Good Az Plumbing, we install and service all major hot water types and brands and can help you choose the best hot water system for your Noosa home based on efficiency, performance and value.
-
Hot water running out quickly usually indicates an issue with system capacity, performance, or component failure. Common causes may include:
Hot water system is too small for the household or business
A faulty thermostat or heating element (electric systems)
Sediment build-up reducing heating efficiency
A failing tempering valve affecting output temperature
Increased usage (guests, longer showers, additional bathrooms being used)
A licensed plumber can test the system, confirm whether it’s repairable, and advise whether an upgrade is a better long-term option. Good Az Plumbing provides hot water diagnostics and repairs in Noosa to restore consistent hot water as quickly as possible.
-
We do both — and we’ll always recommend the most cost-effective option to suit your budget. If the system is in good condition and the fault is repairable (such as a thermostat, valve or element issue), a repair may be the best solution. However, if the unit is older, leaking from the tank body, heavily corroded, or has ongoing performance issues, replacement is often the smarter long-term choice. At Good Az Plumbing, we provide honest advice on hot water system repair vs replacement in Noosa and the Sunshine Coast, along with upfront pricing and reliable workmanship.
-

-
The cost to replace a hot water system in Noosa depends on the type of system (electric, gas, solar, heat pump or instantaneous), the size/capacity, site access, and whether any valves or pipework upgrades are required to meet current standards. After inspecting your existing unit and setup, we provide an upfront fixed-price quote before starting work. As a general guide, smaller electric replacements are usually the most affordable, while heat pump and solar systems cost considerably more due to installation and compliance requirements. At Good Az Plumbing, we supply and install hot water systems across Noosa with honest advice and professional workmanship.
