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

At roughly 188 metres on the plateau, winter nights here run noticeably cooler than the coast, which lifts heating demand and pushes marginal, ageing units over the edge right when residents want long showers most. A system specified for a beachside household can underserve one up here, so elevation goes into every capacity recommendation we make.

The housing stock writes its own rules too

Long-tenured post-war brick homes across the established streets frequently run hot water units well past their service life, while Federation weatherboard cottages often hide cramped plant spaces never designed for a modern tank.

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:

  1. 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.

  2. 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.

  3. 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.

  4. 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

Properties falling toward the gullies on the western side bring access complications most installers meet for the first time on delivery day. A narrow side path, a flight of sandstone steps or a rear yard reachable only across a sloping lawn changes the plan.

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

The growing band of high-rise apartments near the station runs a different equation: shared stacks, body corporate rules and compact laundries where a wall-hung unit beats a floor tank every time.

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

Undersized replacements happen when a swap copies the old tank's rating plate instead of the household's actual habits, so a growing family runs out by Thursday even though the new unit is brand new, which is why we size from usage.

Ignoring the access route

Tight side-access blocks and steep ridge falls complicate delivery, and a tank carried down thirty steps arrives with backs and bruises rather than a plan, which is why we inspect access before quoting rather than discovering it on install day.

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

  1. 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.

  2. 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.

  3. 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.

  4. 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.
