Hot Water Plumbing FAQ's
Why is my Hot Water not working?
Hot water issues can arise from various sources, such as a faulty fuse, heating element or thermostat. While replacing a fuse might be a simple DIY task, other problems require the expertise of a licensed plumber.
Contact us today on 02 8859 0801 and we’ll ensure your hot water is restored promptly.
How much does it cost to install a hot water system?
Replacing a hot water system in the same spot costs $220 to $660, but may rise with additional plumbing or electrical upgrades. Moving the system to a new location can add $1000 to $2000, while switching energy types, like from electric to gas, could cost an extra $1500 to $3000. Upgrading the system’s size may also require more work.

What size water heater should I buy?
The right size hot water system depends on your household size and usage. For electric systems, a 250-litre tank suits 3 people, while 400 litres is better for 5-8. Gas systems need 200 litres for up to 6 people, and 90 litres for 3 or fewer. For solar systems, 180 litres works for 1-2 people, and 400 litres is ideal for 5-6.
Consult a plumber to determine the best system for your needs.
What types of hot water systems are there?
In Australia, water heaters come in four main types: electric (storage or instantaneous), gas (natural or LPG, including storage, instantaneous, and continuous), solar (electric or gas-boosted), and heat pumps.
Which hot water system is most cost-effective?
The best hot water system for your home depends on your household size. Solar systems are generally the most cost-effective, while continuous flow systems are ideal for smaller homes. For medium-sized households, heat pumps or continuous flow systems work well. Larger households may benefit from a gas storage unit or a large heat pump.

Why can’t my leaking hot water heater be repaired?
Once a water heater starts leaking on the outside, it’s usually beyond repair. Leaks typically begin inside the unit, and by the time they become visible, the internal components are often severely rusted. Attempting to fix one leak could cause others to develop. In most cases, replacing the entire unit is a more reliable solution.
If you’re unsure about the source of the leak, our leak detection services can help identify the issue before further damage occurs. If you’re dealing with a gas water heater, it’s best to seek help from professional plumbers to ensure the job is done safely and effectively.
What is the average lifespan of a hot water system?
On average, a hot water system lasts between 8 and 20 years. However, the exact lifespan depends on the type of system and how well it’s maintained. Regular servicing by a plumber every few years can help extend the life of your system and prevent major issues. Proper maintenance is key to ensuring your system lasts as long as possible, so it’s a good idea to schedule regular check-ups with our professional plumbers.
How can I adjust the temperature of my hot water system?
If you’re adjusting your hot water system, proceed carefully. Some systems have an accessible thermostat, usually found behind the access panel, which can be adjusted by turning the temperature dial. After setting, test the water temperature. If the job requires tools or seems complex, it’s best to call a TMV specialist to handle the adjustment safely.
How can I tell if my hot water system is due for an inspection?
Signs that your hot water system may need an inspection include inconsistent water temperature, unusual noises, reduced water pressure, or rusty, discoloured water. Regular inspections every 1-2 years are recommended to catch problems early. If you’re noticing any of these signs, it’s time to have your system checked.

What is the best way to maintain a hot water system?
The best way to maintain your hot water system is by flushing it to remove sediment and ensuring all components, like the pressure relief valve, are in good working order. A well-maintained system will run efficiently and last longer, helping you avoid unexpected breakdowns.
Will a solar hot water system work on cloudy days?
Yes, solar hot water systems come with an electric or gas booster to ensure you always have hot water, even on overcast days.
How long does a solar hot water system last?
With proper maintenance, a solar hot water system can last 15-20 years, making it a durable and cost-effective investment.
Can I switch to solar hot water if I currently have an electric or gas system?
Yes, our team can assess your current system and recommend the best solar hot water option for your household.
