In Melbourne, where energy efficiency and space-saving solutions are increasingly sought after, tankless water heaters have emerged as a popular alternative to traditional storage systems.
The benefits of tankless water heaters include lower running costs, continuous hot water on demand, and a compact design that suits modern urban living. But as with any major home upgrade, it’s important to weigh up your options.
Choosing between tankless vs storage water heaters depends on several factors, like your household size, energy use, and access to gas or electricity. Getting it right can mean greater comfort, better performance, and long-term savings. This article explores the suitability of tankless water heaters for Melbourne households, considering local conditions, regulations, and expert insights.
What Are Tankless Water Heaters?
Tankless water heaters, also known as on-demand systems, heat water directly without the use of a storage tank. When a hot water tap is turned on, cold water travels through a pipe into the unit, where it’s heated by a gas burner or electric element. This ensures a constant supply of hot water without the need for storage. One of the key tankless water heaters advantages is this ability to deliver hot water instantly and continuously, making them ideal for households looking to improve efficiency and reduce energy waste.
Types of Tankless Water Heaters
Electric Tankless Water Heaters
These are often best suited for smaller households or properties without access to mains gas. They’re typically easier and cheaper to install and can be an excellent option in apartments or compact homes in places like Glenroy or North Melbourne. They provide reliable service with fewer installation hurdles but may struggle to keep up with high-demand usage.
Gas Tankless Water Heaters
Designed to handle larger hot water loads, gas models are better suited to families or homes with multiple bathrooms. If you live in suburbs like Essendon or Ascot Vale where gas mains are readily available, this type offers excellent performance and lower running costs. These systems heat water faster and are often more energy-efficient for bigger households.
Typical Installation in Melbourne:
Tankless water heaters are a smart fit for many Melbourne homes, especially in space-conscious suburbs like Essendon and Glenroy. Their compact, wall-mounted design means they can be installed under sinks, inside cupboards, or outside on exterior walls. Ideal for older homes or tighter layouts.
In areas like Ascot Vale or North Melbourne, where heritage homes or modern renos often have limited service areas, their discreet size helps maintain usable space without compromising on hot water access. For larger households in Craigieburn or Thomastown, multiple units may be installed near key areas to ensure strong performance during peak use.
A trusted local plumber in Melbourne can recommend the best placement based on your home’s layout, utility access, and usage needs, while also ensuring it meets local plumbing codes.
Advantages of Tankless Water Heaters for Melbourne Households
Tankless water heaters have been growing in popularity across Melbourne, and for good reason. These systems offer real, practical benefits that suit the way many Melburnians live. So no matter if you’re a small household in North Melbourne looking to save space, or a busy family in Thomastown who can’t afford to run out of hot water, tankless units can offer performance and convenience that traditional systems struggle to match.
Energy Efficiency
Tankless systems can be up to 34% more energy-efficient for households using less than 41 gallons of hot water daily, reducing utility bills significantly over time. With energy prices rising in Victoria, this efficiency translates directly to savings.
Continuous Hot Water Supply
No more cold showers just because someone else got in first. Tankless systems deliver hot water on demand, making them ideal for larger families in suburbs like Tullamarine or Thomastown, where morning routines are anything but quiet.
Space-Saving Design
These units are compact and wall-mounted, freeing up valuable floor space. This is especially useful in older homes or tighter properties in North Melbourne or Ascot Vale, where every square metre counts,
Longer Lifespan
With proper maintenance, tankless water heaters can last over 20 years. That’s almost double the lifespan of many storage systems. That means fewer replacements and better long-term value for your investment.
Challenges and Considerations for Melbourne Homes
While tankless systems offer several benefits, they also come with a few important considerations, especially when it comes to Melbourne’s mix of housing styles, gas availability, and climate.
- Upfront Costs: Installation can be more expensive, especially when retrofitting from a storage system.
- Water Usage Patterns: In areas with high simultaneous hot water demand, like large households in Craigieburn, multiple units or a hybrid system might be necessary.
- Gas Availability: Some newer developments in Thomastown may lack gas connections, making electric models the only option.
- Maintenance Requirements: Regular descaling is essential, especially in areas with hard water, to maintain efficiency.

Melbourne-Specific Factors to Evaluate
