Continuous Flow Gas Hot Water – Supply, Installation, Repairs & Servicing
A continuous flow hot water system (also called “on-demand” or “tankless”) delivers hot water instantly — and only when you need it. Unlike traditional storage tanks, there’s no waiting for water to heat up, no running out in the middle of a shower, and less energy wasted keeping water hot 24/7. That means endless hot water, lower running costs, and a more efficient system that’s perfect for busy households or commercial properties.
At Tomlinson Plumbing, we supply, install, repair and service continuous flow hot water systems from all major brands — matching the right size and features to your home or business needs. So whether your existing unit has failed, you’re upgrading from a storage tank, or you’re building or renovating, we’ll help you choose the right system and make sure it’s installed safely, efficiently and to Australian Standards.

Is a Continuous Flow Hot Water System Right for You?
Continuous flow hot water systems are a great option for many households, but they’re not one-size-fits-all. They’re ideal if you:
-
Want endless hot water without running out
-
Have a growing household with multiple bathrooms
-
Are sick of waiting for a storage tank to reheat
-
Want a more energy-efficient hot water system
-
Are short on space and want a compact, wall-mounted unit
We’ll assess your current setup, water usage and gas supply to make sure a continuous flow system is the right fit for your home before recommending an upgrade.
Benefits of Continuous Flow Gas Hot Water Systems
Switching to a continuous flow system offers some big advantages over traditional storage tanks:
-
Unlimited hot water – no more cold showers when the tank runs out
-
Energy efficient – heats water only when you need it
-
Lower running costs compared to older storage systems
-
Compact design – frees up space around your home
-
Longer lifespan than many traditional hot water tanks
-
Ideal for busy households with multiple bathrooms
If you’re unsure whether continuous flow or storage hot water is better for your situation, we’re happy to walk you through the pros and cons.
Continuous Flow Hot Water Installation & Upgrades
If you’re replacing an old storage hot water unit or installing continuous flow hot water for the first time, we handle the whole process:
-
Removal and safe disposal of your old unit
-
Correct sizing of the new continuous flow system
-
Gas and water pipework upgrades if required
-
Compliance with Australian Standards and Regulations
-
Testing and commissioning of the new unit
-
Clear advice on operation and ongoing maintenance
We’ll always recommend the right size system — undersized units are one of the most common causes of poor performance and customer frustration.
