A real person answers, day or night
A system sized to your household beats a bigger one
Choosing well matters more than choosing big, because an oversized tank quietly burns money for years. Our hot water hub explains each system type, and Thornleigh homeowners can call any day for an honest assessment.
Plateau winters put real demand on your cylinder
Cold nights, long hot showers
Sizing for the season, not the average
Installation work, from sizing to commissioning
Every install we quote covers the complete job: honest sizing, old unit removal, pipework and valve connections, compliance paperwork and full commissioning. Here is the installation work local households and businesses ask for most often:
Gas hot water systems
Gas storage and continuous flow units suit larger family households, and we size the system to your real morning demand, run the gas line and fluing correctly, and commission the tempering valve so showers never swing wildly hot and cold. Our gas hot water systems guide compares the models.
Electric hot water systems
Electric storage tanks remain the straightforward choice where gas is not connected, and we match tank capacity to household size, coordinate any wiring work the connection needs, and set the thermostat for safe, efficient hot water delivery all year round. See electric hot water systems for the detail.
Instant hot water systems
Continuous flow systems heat water only as you use it, which frees up the laundry cupboard or garage wall, never runs out mid-shower, and suits the compact internal layouts found in the older smaller unit developments near the railway station. The instant hot water systems page covers sizing.
Relocations and rough-ins
Extensions, renovated bathrooms and moved laundries often need the system relocated, so we plan the pipework runs, valve positions and drainage for the relief valve before the walls close up, saving you expensive rework once the tiling and painting finish.
What the housing stock means for a new install
Two very different housing vintages
Owner-occupied and long-held
Common problems after a hot water installation
Rusty water from the new tank
Brown or rusty water arriving with a new system usually traces to corroding galvanised supply pipes upstream rather than the unit itself, which is why we test the lines first and quote pipe renewal alongside the installation when needed.
Pressure drops after the swap
Weak flow at the shower following a new installation often points to throttling galvanised pipework or a partially closed valve left from the old setup, so we check the whole delivery path before blaming the brand new cylinder.
Why it matters: the case for doing it properly
A hot water system is a fifteen-year decision with daily consequences: choose badly and you pay for it every morning, choose well and the unit disappears into the background of the household:
- Running costs compound for years An oversized tank heats water nobody uses, an undersized one runs out halfway through the morning queue, and the wrong choice keeps costing you every single day until it is replaced again.
- A failing unit never fails politely Deferred replacements tend to let go at the worst possible moment, flooding a laundry or garage, and a planned install on your schedule always beats an after-hours scramble. Sudden cold water right now is a job for hot water repair or our emergency team.
- The supply side matters as much as the tank A brand new system feeding through corroded pipework delivers disappointing pressure and discoloured water, so testing the lines before the install protects the money you are about to spend.
How it works
How we install your new system, step by step
- 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, commission and prove
We fit the new unit on a compliant base or wall bracket, connect supply, gas and relief pipework to standard, fill and pressure test the tank, then commission the thermostat and the tempering valve and walk you through the controls.

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 Thornleigh
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 Thornleigh 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.
Those four promises are why the phone keeps ringing here, and why most new work arrives as a recommendation from one neighbour to the next.
Where we work
Areas we service along the Northern line
Our crews work Normanhurst, Pennant Hills, Westleigh, Hornsby and Wahroonga every week, alongside the rest of the Hornsby Shire, so the van reaching your street already knows the housing stock, the terrain and the back routes that beat the traffic.
Good questions, straight answers
What locals ask before booking an install
How long does a hot water installation take?
Most standard swaps finish within a single visit once you approve the written price, while relocations or switchovers between gas and electric can stretch to a second visit for wiring or gas line work.
Should I choose gas, electric or instant hot water?
The right choice depends on household size, existing connections and your actual morning usage, so we measure demand honestly on site and recommend the system type that will cost you least to run long term.
Do you take away the old hot water system?
Yes, every installation includes removing and responsibly disposing of the old unit, and we leave the new system commissioned, tested and walked through before we consider the job genuinely finished.
Will old pipes affect my new hot water system?
They can, because corroding galvanised steel pipes restrict flow and discolour water, so we test the pipework first and quote any needed renewals alongside the installation rather than leaving surprises.
Are you licensed to install gas hot water systems?
Yes, our plumbers hold the licences required to disconnect old units, run new gas lines and commission gas systems safely, and compliance certificates arrive with the invoice without you chasing them.
What warranty covers a new hot water installation?
Workmanship is covered by our Lifetime Labour Warranty and the manufacturer warrants the tank and parts on top of that, and we register both warranties for you as part of the job.
