Hot Water Installation Sydney
A new hot water system supplied and installed by one licensed team — gas, electric, solar or heat pump. This page helps you choose the right type, see what's included, and understand what shapes the cost before you commit.
Hot water system installation in Sydney, done properly
Hot water installation in Sydney is rarely just hanging a new box on the wall. The right hot water system installation depends on your home's fuel, your household size, and where the unit sits — which is why we quote on the actual job rather than a brochure price. Whether it's a straight changeover or a first-time hot water installation in Sydney, one licensed team supplies the system, fits it, certifies it and takes the old one away.
We install across all four system types — gas storage and continuous flow, electric storage, heat pump and solar — from the six major Australian brands. If you're not sure which suits your home, that's the first thing we help you work out, because the system you choose sets both the upfront price and what it costs to run for the next decade.
Every install is carried out by licensed plumbers and gasfitters, with a compliance certificate where the work requires one and the old unit removed and disposed of. You deal with one team from the first quote to the final test.
Which hot water system suits your home?
The system type is the biggest decision — it sets both the upfront and the running cost. Here's when each one makes sense.
Gas continuous flow
Endless hot water with no tank, if you have gas. Great for most homes and easy to size up.
Browse gas systems →Electric storage
Lowest upfront cost and simplest install — a tank that suits most homes, with off-peak options.
Browse electric →Heat pump
The efficient electric choice — low running costs and often rebate-eligible. Needs some outdoor space.
Check rebates →Solar
Lowest running cost on a good north-facing roof, with a gas or electric booster for cloudy days.

One licensed team — supply, install, compliance certificate and old-unit removal, start to finish.
What every installation covers
We quote on the actual job, but a standard supply-and-install always includes these essentials.
- Supply of the new system from a major brand
- Licensed removal and disposal of the old unit
- Installation by licensed plumbers and gasfitters
- Compliance certificate where the work requires one
- Tempering valve and fittings to current standards
- Testing, commissioning and a tidy handover
What actually drives your hot water installation cost
The most-searched question is how much a hot water system costs to install — and the honest answer is that two installs of the same unit can differ. This is what shapes your hot water installation cost, and why we quote on your actual site.

From quote to hot water — and how long it takes
No surprises. A straight changeover is often done in a few hours; fuel conversions or relocations take longer, and we tell you which on the quote.
A licensed team — not a DIY job
Why hot water installation is a licensed job, and what that protects.
Hot water installation isn't a DIY job in Australia: gas and electrical connections must be made by a licensed gasfitter or plumber, and a compliance certificate is required for much of the work. Installing a system yourself can void the manufacturer's warranty and your home insurance, and it's genuinely dangerous with gas.
That's who we are — licensed plumbers and gasfitters who install hot water every day across Sydney. You get the job done once, done to standard, certified, and backed by warranty, rather than a weekend project that fails an inspection.
