A New System Starts With the Right Choice, Not the Catalogue
Picking a unit before understanding how your household actually uses hot water is how undersized tanks and wasted money happen. We assess first, quote second, and only then lift a spanner. Call (02) 9072 0520 to talk it through with a licensed plumber.
Installing on the Plateau Changes the Specification
Elevation rewrites the sizing maths
The housing stock writes its own rules too
The install plan has to fit the house it lands on, not the other way around.
How it works
Installation Work We Cover, Start to Finish
Every install below is quoted as one fixed written price before work begins, completed by licensed plumbers, and commissioned with temperatures, pressures and safety valves tested in front of you:
- 01
Gas Continuous Flow
Gas continuous flow units heat water only as it is used, so a compact wall-mounted unit on a weatherboard laundry wall frees the floor an old tank hogged and endless hot water suits busy families running back-to-back evening showers comfortably. More on gas hot water systems.
- 02
Electric Storage
Electric storage tanks remain the practical choice where gas is not connected, sized honestly to the household, fitted with a tempering valve, and positioned so clearances and supply requirements are met without compromise on blocks of every shape and size. See electric hot water systems.
- 03
Sizing and Upgrades
System sizing comes from actual usage rather than guesswork, so we count bathrooms, tally occupants and check simultaneous demand, then recommend a tank size or flow rate that handles the weekday school-morning peak without the final shower ever turning cold.
- 04
Relocations and Rough-Ins
Relocations and renovation rough-ins get planned around the finished layout, with pipework rerouted, valves repositioned and the new unit mounted clear of the eaves, so the laundry wall reads tidy again and services every fixture efficiently right throughout the year.
How the Local Streets and Units Install Differently
Access on the steep blocks
We walk the access route before quoting, so the price already includes getting the unit where it needs to go. Instant hot water systems sometimes solve the space problem entirely.
Units along the corridor
Installing into a unit means coordinating with building management and confirming the strata's requirements before the truck arrives, which we handle as part of the job.
Problems That Ruin New Installs Before Their Time
Copying the old unit's label
Ignoring the access route
If your current system has simply failed and you need hot water today rather than a planned install, that is a different job with different urgency, and our emergency team handles it around the clock.
Why Getting the Install Right the First Time Matters
Efficiency compounds over a decade
A correctly sized, properly commissioned system costs less to run every single year it operates, while a badly matched one quietly overworks from day one and dies young, taking your investment with it.
Compliance protects the paperwork and the people
Tempering valves, gas commissioning and correct clearances are not box-ticking; they are the difference between an install that is safe and insurable and one that is a liability waiting for an inspector or an incident.
Relocation decisions deserve a second opinion
An end-of-life unit often tempts a simple like-for-like swap, yet a relocation or source change made at install time can serve the household far better, which is where our hot water replacement and hot water repair pages help you weigh the options.
How it works
How a New Hot Water Install Works
- 01
Call and tell us
Ring (02) 9072 0520 and describe what's happening, and a licensed plumber, not an answering machine, will tell you what it likely means, what to stop using, and when we can realistically be there.
- 02
Quote before work
Your plumber inspects the job properly, runs whatever diagnosis it genuinely needs, and hands you a single fixed written price covering the complete fix, with a $0 call out fee and nothing added afterwards.
- 03
Install and commission
We mount the unit, connect and pressure-test the gas or power supply, set the tempering valve to safe limits, then run every fixture hot and record temperatures and pressures so you see the system proven working before the invoice is raised.
- 04
Backed for life
Everything we complete is covered by our Lifetime Labour Warranty, the promise that outlasts the job itself: if it's not right, we come back. No questions. No cost.
Why Choose Your Plumber Hornsby
Fixed prices, kept
Every job is priced upfront in plain writing before any work starts, the invoice always matches that number, and weekend or late-evening timing changes nothing, because overtime rates simply don't exist here.
Licensed and insured
Your Plumber Hornsby works under licence #275278C with full insurance behind every job, and the compliance certificates that protect your home's paperwork trail arrive with the invoice, without you ever needing to ask for them.
Lifetime Labour Warranty
Workmanship here is guaranteed for life under our Lifetime Labour Warranty rather than for a warranty card's fine-print window, which says more about how the work is done in the first place than any advertisement could.
Genuinely local response
We work these streets constantly rather than commuting in from across Sydney, so the van reaching you has usually just left a job nearby, stocked for the faults the local houses actually develop.
Where we work
Areas We Service
Installation work runs wherever the vans travel: Waitara, Asquith, Mount Colah, Normanhurst and Hornsby Heights all sit inside the regular rounds, so a household one suburb over receives the same fixed pricing, licensed installers and lifetime backing. See the services hub.
Good questions, straight answers
Hot Water Questions Hornsby Locals Ask
How long does a hot water installation take?
Most straightforward swaps are finished within a single day, while relocations, source changes or renovation rough-ins can stretch to two days once pipework, valves and compliance testing are all properly completed.
Should I choose gas or electric for a new system?
Gas continuous flow suits households with a connected supply and high simultaneous demand, electric storage remains practical where gas is absent, and we match the source to your block and usage honestly.
Do I need council or Sydney Water approval for an install?
Like-for-like replacements generally need no approval, but relocations, source changes or work affecting drainage can trigger requirements, and we confirm the compliance path with Sydney Water before any work begins.
Can a new system be installed where the old one stands?
Usually yes, provided clearances, access and current standards are met, and where the old position no longer complies we present relocation options in the fixed quote before anything is ordered.
What warranty comes with a new hot water system?
Manufacturer warranties cover the tank and components while our Lifetime Labour Warranty covers the workmanship, so if anything we installed is not right, we return and make it right at no cost.
How often should a hot water system be serviced?
A check every two years keeps tempering and pressure valves healthy and catches corrosion early, and our maintenance plumbing team can fold that inspection into a broader annual household service visit.
