Hot water accounts for roughly 25% of energy use in the average Australian home. It’s the second biggest energy expense after heating and cooling. Choosing the right system type, keeping it well maintained, and knowing when repair makes more sense than replacement can save thousands of dollars over the life of the unit.
There are four main types of hot water system available in Sydney: electric storage (the most common, with a tank that keeps water hot around the clock), gas storage (similar tank but heated by a gas burner), gas continuous flow or instantaneous (heats water on demand as you use it, no tank), and heat pump (uses a refrigeration cycle to extract heat from the air, extremely energy-efficient). Solar systems use roof panels to heat water and typically have an electric or gas booster for cloudy days.
When deciding between repair and replacement, we consider the age of the unit (most tanks last 8 to 12 years), the cost of the repair versus the age-adjusted remaining lifespan, the energy efficiency of the current system versus a modern replacement, and any government rebates available. For example, replacing an old electric storage system with an eligible heat pump can attract rebates starting from $200 under current NSW and federal programs, sometimes significantly more depending on the model and your circumstances.
We stock parts for most major brands on our vans: Rheem, Rinnai, Dux, Bosch, AquaMax, Thermann, Vulcan, and Stiebel Eltron. For common faults like a failed thermostat, heating element, or pressure relief valve, we can often diagnose and repair on the same visit. For replacements, we carry popular tank and continuous flow models and can usually have your new system installed and hot water running the same day you call.
Every installation is done to Australian Standards, pressure and temperature tested, and fitted with a compliant tempering valve (required by law to limit hot water at bathroom taps to 50°C to prevent scalding). We issue compliance certificates where required and back all our work with a lifetime workmanship guarantee in addition to the manufacturer’s warranty on new units.

Local Plumber When You Need One
Questions We Get Asked
- Can you fix my hot water system or do I need a new one?
- We always check if repair is viable first. We consider the unit’s age (most tanks last 8 to 12 years), the cost of repair versus the remaining expected lifespan, and energy efficiency. We give you the numbers for both options so you can make an informed choice. No pressure to replace if repair makes sense.
- Which hot water brands do you work on?
- We work on all major Australian brands: Rheem, Rinnai, Dux, Bosch, AquaMax, Thermann, Vulcan, Stiebel Eltron, Chromagen, Everhot, and Apricus. If you have a less common brand, call us. We can usually still help.
- How long does a hot water system replacement take?
- Most like-for-like replacements are done in 2 to 4 hours including removal of the old unit, installation, connection, testing, and cleanup. You’ll usually have hot water back the same day you call.
- Do you install solar hot water and heat pumps?
- Yes. We install, repair, and service solar hot water systems and heat pump units. Heat pumps are an excellent option for reducing energy costs. They use roughly one-third the electricity of a traditional electric storage system.
- Are there government rebates for hot water?
- Yes. Eligible heat pump and solar hot water replacements can attract rebates under both NSW and federal programs. The amount varies by model and circumstances, typically starting from $200 and sometimes significantly more. We can advise on eligibility and help you access available rebates and Small-scale Technology Certificates (STCs).
- What warranty do you offer on hot water work?
- All our hot water work carries our lifetime workmanship guarantee. If our work fails, we fix it free. New units also come with the manufacturer’s warranty, typically 5 to 10 years on the tank and 1 to 3 years on components depending on the brand and model.
- What are signs my hot water system is failing?
- Common warning signs include: water not getting as hot as usual, running out of hot water faster than normal, rusty or discoloured hot water, rumbling or popping noises from the tank, visible leaking or pooling around the base, and the pressure relief valve dripping constantly. If your system is over 10 years old and showing any of these signs, it’s worth having it assessed.
- Electric vs gas vs heat pump. Which is best?
- It depends on your household size, gas availability, roof space, and budget. Gas continuous flow is excellent for unlimited hot water on demand with low running costs if you have natural gas. Heat pumps have the lowest running costs overall but higher upfront cost (offset by rebates). Electric storage is cheapest to buy but most expensive to run. We’ll assess your situation and recommend the best option for you, not the most expensive one.
- What is a tempering valve and do I need one?
- A tempering valve mixes hot and cold water to limit the temperature at bathroom taps to a maximum of 50°C, preventing scalding. It’s required by Australian Standards (AS/NZS 3500) on all new hot water installations and replacements. We install and test tempering valves as part of every hot water job.
- My hot water is discoloured. Is it safe?
- Rusty or brown hot water usually indicates corrosion inside the tank (the sacrificial anode may be depleted). While the water isn’t typically dangerous, it stains laundry and fixtures and indicates the tank is deteriorating. If the unit is over 8 years old, replacement is usually the better option. If it’s newer, we may be able to replace the anode rod to extend the tank’s life.
