Hot water systems we work on
Flow Now Plumbing works on every common type of hot water system, and all brands:
-
Gas storage:Â a tank that heats and stores water using gas.
-
Gas continuous flow (instantaneous): heats water as you use it, so it doesn't run out.
-
Electric storage: a tank heated by an electric element, often on off-peak power.
-
Heat pump:Â an electric system that draws heat from the air, using much less power than a standard electric tank.
-
Solar: roof panels heat the water, with gas or electric boosting when the sun isn't doing enough.
Flow Now Plumbing isn't a dealer or authorised agent for any brand, so you'll get straight advice on the system that suits your home.
Hot water repairs
Most hot water problems can be tracked down on the first visit. Common repairs include:
-
No hot water at all
-
Water not getting hot enough, or running out quickly
-
A leaking tank, valve or pipework
-
A pilot light that won't stay lit, or a continuous flow unit showing an error code
-
Water dripping from the relief valve
-
Banging, rumbling or other unusual noises
-
Rusty or discoloured hot water
Your plumber will explain what's wrong, what it will cost to fix, and whether it's worth repairing or time to replace.
Hot water replacement
If your tank is leaking from the body, badly rusted or simply worn out, it's usually time for a new one. Flow Now Plumbing removes the old system, fits and connects the new one, then tests it to make sure everything is working properly before leaving. You can replace like for like, or get advice on a different type if it will suit your household better.
New hot water installs
Building, renovating or adding a second system? Flow Now Plumbing installs new hot water systems of every type, including the gas and water connections. With plumbing and gas fitting covered under the one licence, there's no need to book a separate gas fitter.

Hot water FAQs
Should I repair or replace my hot water system?
It depends on the fault and the age of the system. A faulty thermostat, element or valve can usually be repaired. If the tank itself is leaking or badly rusted, it's normally time to replace it. Flow Now Plumbing will give you an honest recommendation either way.
What types of hot water systems do you work on?
All of them: gas storage, gas continuous flow, electric storage, heat pump and solar. Flow Now Plumbing repairs, replaces and installs all types, and works on all brands.
Can you convert my gas hot water to electric or a heat pump?
Yes. Flow Now Plumbing carries out gas to electric and heat pump conversions. The old gas system is removed, the gas line is made safe, and the new system is installed and commissioned.
Do you handle Solar Victoria or VEU rebates?
No. Flow Now Plumbing doesn't process Solar Victoria or VEU rebates. If you want to apply for one, check the program's requirements before you book.
