If you’re in the market for a gas instantaneous hot water system in Perth or just weighing up whether gas is the right fit for your home, this guide walks through the main points to consider. Ahead, we’ll cover how the technology works, its best benefits, what makes Perth a prime location for gas units specifically, and what to keep an eye out for when choosing the right model for your home.
Your Guide to Gas Instantaneous Hot Water Systems in Perth
Gas instantaneous hot water systems have reshaped the way many households manage their daily hot water use. And a big part of their appeal comes from the simplicity of the design. Water heats the moment you need it, so the system avoids the constant energy use that storage tanks rely on. Homes get steady temperature control, dependable pressure, and a setup that does not run out halfway through a shower. Plus, as energy costs rise and space becomes limited in newer builds across the city, these systems are quickly becoming a very practical upgrade that offers real day-to-day value.
How Gas Instantaneous Hot Water Systems Work
Unlike traditional storage units, gas instantaneous systems have no tank. That said, when a hot water tap is turned on, cold water flows through a heat exchanger. Then, a gas burner ignites beneath that exchanger and rapidly heats the water as it passes through. And within seconds, hot water is delivered straight to your tap.
The heating process is fast and quite efficient for homes using natural gas or LPG, and there’s no energy or space wasted keeping a large tank of water hot. Plus, no risk of running out mid-shower because the kids used it all before you!
Why Gas Hot Water Systems Work Well in Perth
Energy Efficient
Gas burners heat water very quickly and without relying on constant electrical input. This reduces running costs, specifically in homes with frequent hot water use.
Small Size
For many Perth homes, especially newer builds and townhouses, space is valuable. These tankless units mount neatly on an external wall.
Unlimited Hot Water
The flow-based heating design means you aren’t waiting for a tank to replenish. Hot water continues as long as you need it, as long as the system is sized correctly.
Fast Recovery
Even during colder winter mornings, a gas system will maintain consistent temperature and pressure.
There are two brands known to dominate the market for gas continuous flow systems in Australia, and they are Rheem and Rinnai. Both offer strong reliability and long warranties, but each has particular strengths worth noting when making a decision for your home.

Rinnai is famous for high-efficiency burners and precise temperature controllers, which allow you to set your water temperature digitally. This is especially useful for families with young children or households wanting tighter control or restrictions over energy use.

What to Consider Before Choosing a New Hot Water System in Perth
1. Size and Flow Rate
2. Gas Type
3. Installation Location
4. Temperature Controllers
5. Maintenance
Instantaneous systems are sized by flow rate (litres per minute). A small unit won’t keep up with two showers running at once. A larger home often requires a 20-26 L/min system.
Homes connected to natural gas can install most standard systems, but LPG users need models compatible with bottled gas. This will be noted on product specifications.
Units must be installed externally in most cases to meet ventilation and safety standards. Wall space near plumbing lines is essential.
Some models allow bathroom or kitchen-mounted controllers for precise adjustments, which can greatly help prevent scalding and improve efficiency.
Even with long lifespans, gas systems benefit from periodic servicing to check burners, filters, and general operation.
Selecting the Right System for Your Home
With rising electricity prices and the hefty cost of heating tanks around the clock, many households are feeling encouraged to move to gas. And while the upfront cost of a gas instantaneous unit may be higher, the lifetime savings typically outweigh the initial spend, especially for families with higher daily hot water usage.
