A real person answers, day or night
No Tank, No Waiting, No Cold Surprise
A continuous flow unit suits apartment living beautifully: no cylinder eating a cupboard, no last-of-the-tank sprints, just hot water for as long as the tap runs. Call (02) 9072 0528 and we'll talk you through the options honestly.
Compact Units, Dense Streets and Older Gas Lines
This suburb's housing makes the case for continuous flow better than almost anywhere. Census figures put flats and apartments at over 80% of dwellings here, a mix of interwar walk-ups, 1960s-1980s red-brick units and newer infill towers, and few of those floor plans were ever designed around a bulky storage cylinder.
- Existing gas helps Pre-1940 Federation and Arts and Crafts houses on the harbour-facing ridges often carry established gas connections, which makes a gas continuous flow unit a natural fit during the renovations these homes regularly undergo.
- The Junction lifestyle suits it Around Neutral Bay Junction and the Big Bear precinct, cafe-dense streets and young-professional households use hot water in short sharp bursts rather than long hauls, which is precisely what on-demand heating is built for.
- Space is the real currency A unit mounted on the wall frees the laundry or cupboard a tank consumes, and in walk-up blocks where every square metre counts, that reclaimed space is worth as much as the endless hot water.
What We Fit and Service
We cover the full instant hot water scope: sizing the unit to your household's real peak demand, removing the old tank, commissioning the new system under load and leaving the compliance paperwork where you can find it.
Sizing and selection
We calculate the peak simultaneous demand your household actually places on hot water, check gas supply capacity or existing circuits honestly, and recommend a unit whose flow rate genuinely covers two showers and a kitchen running together rather than whatever happens to be on special.
Gas continuous flow
Gas instant systems suit the established gas connections common around the older blocks here, delivering endless hot water on demand. We upgrade undersized supply lines, set correct flue clearances, commission the burners properly and leave the unit tuned for lasting efficiency rather than a first-week honeymoon.
Electric instant units
Where gas isn't connected, electric point-of-use and whole-home instant units fill the gap neatly, with off-peak wiring and supply arrangements handled as part of the install. Small households get hot water on demand without ever paying to keep water warm overnight.
Tank-to-instant swaps
Swapping a dying storage cylinder for a compact continuous flow unit reclaims the space the old tank ate and ends end-of-life failures outright. We cap redundant pipework, mount the new unit neatly, and the old tank leaves with us.
How These Buildings Actually Fail
- Winter is the crunch With thousands of ageing systems across the interwar and mid-century stock, the oldest unit on the line gives out on the coldest morning, and in shared buildings one dead plant room can cold-shower an entire block at once.
- Continuous flow changes that picture No tank to corrode through, no stored volume to run out of, and a wall-mounted unit a plumber can service without emptying a shared laundry.
- The least dramatic option wins For households up the steep lanes and down toward the harbour, on-demand heating simply removes the failure modes everyone dreads, which is exactly why we like fitting them.
Instant System Faults We See Here
Temperature swings between outlets
A shower running hot then cold usually traces to an undersized unit, a clogged inlet filter or a gas supply starving the burners under load, and all three are straightforward diagnoses for a plumber who knows these systems inside out and tests rather than guesses.
Flow drops to a trickle
Instant units restrict flow to heat water properly, so a scaled heat exchanger, a partly closed isolation valve or a strangled supply line shows up first as a weak shower, and we fix the underlying cause instead of selling you a bigger unit on the spot.
Ageing units past their best
Older continuous flow systems develop failed solenoids, corroded heat exchangers and erratic control boards, and where repairs stop making economic sense we quote honestly on replacement with a modern, warranty-backed unit, often fitted the same visit rather than strung across a week.
Why Fitting It Right Matters
- A failing unit picks its moment Instant systems rarely die quietly; they fade through lukewarm mornings and pressure dips before giving out completely, usually on the coldest day of the year when every other job in the street is urgent too.
- Sizing errors cost you twice An undersized unit disappoints every single day, while an oversized gas model burns more than it should; getting the calculation right once protects both your comfort and your running costs for the unit's working life.
- Small faults become big bills A slow leak from an inlet fitting on a wall-mounted unit drips onto whatever sits beneath it, and in a stacked apartment building that damage rarely stays confined to your own ceiling or your own insurance claim.
How it works
How the Job Works
- 01
Call and tell us
Ring (02) 9072 0528 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
Fit, commission and verify
The old tank is isolated, drained and removed, the instant unit is mounted, connected to gas or supply and set to a safe delivery temperature, then every outlet is run under load and the compliance paperwork is left with the invoice.
- 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 Neutral Bay
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 Neutral Bay 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.
Common valves, fittings and flue components ride on the van, so most instant system installs finish in one visit. If the morning has already beaten you to it, our no hot water page covers the urgent path, and hot water repair covers fixing what's still worth saving.
Where we work
Areas We Service
We fit and service instant hot water systems across the local patch and beyond, covering Cremorne, Kirribilli, North Sydney, Cammeray and Kurraba Point, bringing the same compact-apartment expertise whether your building faces the water, sits along the commercial spine or climbs one of the steep ridges.
Good questions, straight answers
Instant System Questions Neutral Bay Locals Ask
How long does an instant hot water system last?
A quality continuous flow unit typically serves a household for fifteen to twenty years with basic servicing, comfortably outlasting most storage tanks before corrosion or wear forces a decision.
Can one instant system run two showers at once?
A correctly sized unit can, so we calculate your peak simultaneous demand before recommending a flow rate, which is exactly how an undersized disappointment gets avoided in the first place.
Do instant systems cost more to run than storage tanks?
They skip the standby losses of a tank reheating water nobody is using around the clock, which often leaves running costs lower despite the higher upfront price of the unit.
Do you install both gas and electric instant systems?
Yes, we fit gas continuous flow units and electric instant models, upgrade supply lines or circuits where the original setup falls short, and leave every job with full compliance paperwork.
Can an instant system be fitted inside an apartment?
Usually yes, because a wall-mounted unit occupies a fraction of the space a storage cylinder demands, though gas models need a compliant flue path that we always assess on site first.
Will my existing pipes cope with a new instant system?
In older buildings we test supply lines and pressure before fitting the unit, then upgrade anything undersized so the new system performs properly from its very first shower onward.
