What’s the difference between a plumber and a hot water specialist? 

When it comes to maintaining your home’s plumbing, it’s important to know the distinction between a regular plumber and a specialist hot water plumber.

While a regular plumber is trained to handle a variety of tasks such as fixing leaks, installing fixtures, and managing general plumbing systems, a hot water specialist focuses specifically on hot water systems. These specialists have advanced knowledge in the installation, repair, and maintenance of water heaters, ensuring optimal performance and energy efficiency. Understanding the difference can help you choose the right professional for your plumbing needs.

Hot water system FAQs.

How long will my hot water system last?

The longevity of your hot water system depends on the type and how well it’s maintained. Conventional storage units generally have a lifespan of 8 to 12 years, while tankless (instant) systems can often exceed 20 years if properly cared for.

What size hot water system do I need?

The right capacity depends on the number of occupants and how much hot water you typically use. Here’s a rough guide:

  • 1–2 people: 50L–100L
  • 3–4 people: 125L–250L
  • 5 or more people: 250L–400L+

For continuous flow systems, it’s important to consider the required flow rate (litres per minute) based on simultaneous water usage.

How do hot water systems work?

Hot water systems use either electricity or gas to heat water. In storage systems, hot water is kept in an insulated tank, ready for use. In tankless (or instantaneous) systems, water is heated on demand as it flows through the unit.

Gas vs electric hot water systems – what’s the difference?

Gas HWS tend to heat water more quickly and can operate during power outages, often providing lower ongoing costs with access to natural gas.

Electric HWS are generally easier and cheaper to install but may cost more to run, depending on electricity tariffs.

Which hot water brands are the most reliable?

Well-regarded brands in Australia include Rheem, Rinnai, Bosch, Stiebel Eltron, Dux, and Thermann. The best brand and model for your home depends on your household size, budget, and energy preferences.

Water heater troubleshooting tips.

Why isn’t my hot water system working?

Several factors could be at play – from power or gas supply issues to a malfunctioning thermostat, heating element failure, or sediment build-up inside the tank.

For advice and assistance, contact our friendly team. We’re here to help.

No hot water at all?

Start by checking your power or gas supply. For electric systems, ensure the circuit breaker hasn’t tripped.

For gas systems, the pilot light may need to be relit. If everything seems in order and there’s still no hot water, it’s best to call in a professional (like our team) to assess the issue. Contact us for help.

There are unusual noises coming from my water heater

Popping, banging or hissing noises often suggest sediment build-up inside the tank. This can cause overheating and the formation of steam bubbles. Flushing the tank can sometimes resolve the issue — or we can do it for you quickly and safely.

Help, my water heater is leaking. 

Leaks are usually caused by corrosion, loose pipe fittings, or a faulty pressure relief valve. If the tank itself is leaking, it’s likely time for a replacement unit. Get in touch for advice.

Why is my hot water not getting hot enough? 

If your water is only lukewarm, the thermostat may need adjustment, or there could be sediment affecting the heating element’s performance. Contact us to book a service call. Once onsite, we can pinpoint the cause and restore proper function fast.

Do you need to reset your hot water unit?

Most systems have a reset button located on the thermostat or control panel. Pressing it may temporarily restore operation — but if the problem persists, book a professional service to avoid further issues.

Why does my hot water smell bad?

A sulphur or “rotten egg” smell is usually due to bacteria reacting with the anode rod inside your tank. Swapping it out for an aluminium-zinc rod can solve the problem. We carry replacements and spare parts in our service vehicles.  Contact us for assistance.

My water heater keeps switching off

If your hot water unit keeps cutting out, you may be dealing with overheating, a gas supply issue, or a thermostat fault. Our licensed technicians can diagnose and repair it efficiently.

Why am I experiencing low hot water pressure?

This could be caused by sediment clogging your pipes, a partially closed valve, or issues with your pressure regulator. We can help you identify and fix the problem quickly.

Water heater installation and service.

What’s the cost to install a new hot water system?

The price to install a hot water heater in Australia typically ranges from $500 to $2,500, depending on factors such as the system type (electric, gas, solar or heat pump), its size, and the complexity of the installation. Additional costs may apply for relocating the unit, upgrading pipework, or installing tempering valves.

How do I flush my hot water system?

To flush your hot water heater, turn off the power (or gas), attach a garden hose to the drain valve, open the valve and allow water to flow out until it runs clear. This helps remove sediment that can reduce heating efficiency. It’s a straightforward process, but if you’re unsure, we’re happy to assist or walk you through it. Book a service or call for advice.

How often should I drain the tank?

It’s recommended to flush and drain your hot water system at least once a year to prevent sediment build-up, extend the lifespan of the unit, and keep it operating efficiently. During a scheduled maintenance visit, we can also check other components such as the anode rod, valves, and thermostat to ensure everything’s running smoothly.

Should I repair or replace my hot water heater?

If your system is more than 10 years old, leaking, or requiring frequent repairs, it might be more economical to replace it. Repairs can add up over time, and newer models are more energy-efficient. If your system is still under warranty, we can help you determine what’s covered and whether it makes sense to repair or replace.

Can I install a hot water heater myself?

In most cases, no. Australian regulations require a licensed plumber or electrician to carry out hot water system installations. DIY installation can void your warranty, compromise your home insurance, and pose safety risks. Our qualified team ensures your system is installed safely, legally, and up to code — so you can enjoy reliable hot water without worry.
