A real person answers, day or night
Never run out, never heat a tank
A tank keeps forty or fifty litres hot around the clock whether you need it or not.
A continuous flow unit does nothing until a tap turns, then heats exactly what passes through it, so the shower at the end of a full house never runs cold. If your existing system is repairable rather than finished, our hot water repair team will tell you honestly before anyone talks replacement.
What makes instant systems different around here
- Units and walk-ups dominate The suburb mixes interwar houses with a large apartment stock, and the first block of flats arrived in 1962, so many homes simply never had the cupboard space or balcony area a storage tank demands.
- Gas infrastructure has history Homes plumbed for gas decades ago help continuous flow installation, but the ageing fittings and risers behind those walls need checking before a new unit hangs on them.
- Winter failures cluster The seasonal pattern here runs to hot water breakdowns in the colder months, and a unit with no tank to corrode removes one of the most common failure points outright.
Our instant hot water services
Every job starts with what the household actually does: how many showers run at once, how far the unit sits from the tapware, what the existing supply can genuinely feed. From there the work is straightforward, certified and priced in writing before a tool comes off the van.
Sizing and selection
We calculate flow rate from the fixtures you actually run simultaneously and the incoming water temperature in winter, then match a unit whose capacity covers the real demand, because an undersized continuous flow unit delivers a lukewarm trickle at exactly the worst moment.
Installation and commissioning
The new unit is mounted, connected to gas or power, fitted with the correct pressure and tempering arrangements, then tested end to end, and compliance certificates are lodged so the paperwork trail protecting your home arrives finished, not pending.
Supply line assessment
Older connections in the interwar and post-war homes common through the village are inspected for capacity and condition before any unit is fitted, because a continuous flow system draws harder than the storage unit it replaces and the supply must genuinely keep up.
Fault finding and servicing
Ignition lockouts, error codes, flow sensors and scaled heat exchangers are the usual faults on continuous flow units, and we diagnose the actual component rather than swapping parts hopefully, then service the unit so it stays reliable.
Replacements and changeovers
Swapping an old tank for a continuous flow unit involves capping the old footprint, resizing connections and updating the compliance trail, work we coordinate with owners corporations where the unit sits on common property in a block of flats.
Where the housing stock shapes the job
The falls from the ridgeline down toward Tambourine Bay and the river mean services run long distances through wall cavities and under floors on many blocks.
- Position matters A continuous flow unit placed badly adds metres of dead-leg piping that wastes both water and patience at the tap, so we site units where the pipework already lives.
- Double-brick slows everything Running new lines through brick and render is slower and messier than timber framing allows, which is why the mounting point gets chosen before the quote, not after.
Ferry access on the river and the absence of a railway station have kept this a compact, self-contained village, and the housing reflects it: homes renovated in place, over decades, layer by layer, each with its own plumbing history to respect.
Common problems with instant systems
Lukewarm flow in winter
Incoming water temperatures drop sharply through the depths of a Sydney winter, and a unit sized generously for summer can fall short on a July morning, so we recalibrate the temperature setting or resize the unit to match the genuine year-round demand of the household.
Error codes and lockouts
Modern units self-diagnose and shut down on ignition faults, flame failure or flow sensor errors, and because the codes point to specific components, we test the named part properly rather than resetting the unit and hoping the fault has moods.
Fluctuating temperatures
Temperature swings between showers usually trace to a flow sensor drifting, a scale build-up on the heat exchanger or a tempering valve failing, and in the older double-brick homes where pipes run through warm wall cavities, the diagnosis starts there.
Why it matters
- An undersized unit fails at the worst moment Winter mornings here already cluster into hot water failures across the older homes and flats, and an instant system chosen without proper sizing joins them, so the calculation done before installation is the whole job.
- Old gas lines hide the real cost A continuous flow unit connected to ageing fittings or an undersized riser works badly or works dangerously, which is why the supply assessment comes first and the honest answer sometimes includes a line upgrade.
- Compliance protects the property Gas work carries certification requirements, and in apartment blocks the owners corporation needs the paperwork clean, so a properly lodged installation protects both the household and the building's records.
How it works
How the work runs
- 01
Call and tell us
Ring (02) 9072 0504 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
Size, supply and install
We measure the household's genuine simultaneous demand, check the gas or power supply against it, then mount and connect the selected unit with the pressure, tempering and flue arrangements the manufacturer specifies, testing temperatures and flows at every fixture before we sign the job off.
- 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 Lane Cove
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 Lane Cove 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.
If a storage system suits your household better, our guides to gas hot water systems and electric hot water systems compare the alternatives honestly, and hot water replacement covers the end-of-life path.
Where we work
Areas we service
Alongside the village itself, our continuous flow installations and servicing reach Lane Cove North, Lane Cove West, Greenwich, Longueville and Riverview, with the same fixed written pricing whether the job sits on a ridgeline block or down the long fall toward the water.
Good questions, straight answers
Instant system questions locals ask
Are instant hot water systems more efficient to run than tanks?
A continuous flow unit avoids the standby losses of a stored tank, so for households with modest simultaneous demand the running costs are usually lower, which we confirm against your usage before quoting.
Can a continuous flow unit be installed in an apartment?
Yes, provided the owners corporation approves the work and the existing gas or power supply supports it, and we handle the compliance paperwork and coordinate riser isolation for common installation points.
How long does an instant system last?
Quality continuous flow units commonly serve fifteen to twenty years with periodic servicing, and because they hold no stored water, they avoid the tank corrosion that ends storage systems early.
Do instant systems work with older gas lines?
They do, but older lines sometimes need sizing checks or upgrades to supply the unit properly, which is why we inspect the existing pipework before recommending a model rather than after.
What size instant system does my home need?
Sizing depends on how many fixtures you realistically run at once and the temperature of incoming water in winter, and we calculate it from your fixtures rather than guessing from floor area.
Is there a warranty on the installation?
Every installation carries our Lifetime Labour Warranty alongside the manufacturer's parts warranty, so if anything in our workmanship falls short, we return and make it right at no cost to you.
