Instant Hot Water Systems Brisbane — Endless Hot Water on Demand

Running out of hot water halfway through a shower isn’t just frustrating — it’s avoidable.
At CK Plumbing, we specialise in the installation and maintenance of instant (continuous-flow) hot water systems that deliver endless hot water while saving energy.
With more than 15 years serving Holland Park, Mount Gravatt, Coorparoo, Carina, and Brisbane’s Southside, we help homeowners upgrade to efficient, space-saving systems built for Australian conditions.

What Is an Instant Hot Water System?

An instant or continuous-flow system heats water only when you turn on the tap — no storage tank, no wasted power reheating water you’re not using.
When the tap opens, sensors ignite a gas burner or activate an electric element that warms the water as it passes through the unit.

Key advantages:

  • Endless hot water — ideal for families.
  • Compact design fits outdoors or in tight spaces.
  • Lower running costs compared to large storage tanks.
  • Minimal heat loss, improving energy efficiency.
  • Suitable for both gas and electric connections.

Signs It’s Time to Upgrade

If your old storage tank is showing its age, an instant system can save both money and space.
You may benefit from an upgrade if you notice:

  • Limited or inconsistent hot water supply.
  • Rust, leaks, or corrosion around your current tank.
  • Rising energy bills.
  • Lack of space for a full-size cylinder.

Our team can inspect your current setup and advise whether an instant gas or instant electric system suits your home best.

Our Installation Process

Step 1
Site Assessment

We check gas or electrical capacity, water flow rate, and venting to ensure safe installation

Step 2
System Selection

Together we choose the best model for your household — from compact Rinnai Infinity and Rheem Continuous Flow units to robust Bosch Condensing systems.

Step 3
Professional Installation

Our licensed plumbers and gas fitters connect all lines to Australian Standards AS/NZS 3500 and AS/NZS 5601, test for leaks, and commission the unit.

Step 4
Clean-Up & Demonstration

We remove the old unit, tidy the area, and show you how to operate and maintain your new system for peak efficiency.

Gas vs Electric Instant Hot Water

  • Gas Instant Systems:
    Efficient and reliable, ideal for larger households. Operate independently of electricity during blackouts.

  • Electric Instant Systems:
    Compact and simple for smaller homes or apartments with limited gas access.
    → See Electric Hot Water Systems.


We’ll help you compare running costs, flow rates, and warranty options before making a final decision.
