The system that heats water the moment a tap opens, and never stops
Continuous flow heating means no tank, no recovery wait and no cold surprise, and it suits the family homes here that run showers, dishes and laundry through the same busy hour. Call (02) 9072 0504 to talk it through.
Why continuous flow suits these older streets
- Tanks past their design life Many interwar and 1950s homes between renovations still run storage units long past their design life, often failing in cramped side passages where removal access is genuinely awkward.
- Walls built for wall mounting Brick, double-brick and brick-veneer construction gives a continuous flow unit sound mounting on almost any wall, with short flue runs and no tank footprint to find.
- School-run demand, met Busy family households get endless delivery through the morning peak, so the last shower runs at temperature even after the dishwasher and the laundry have both had their turn.
What we install and service
Every continuous flow job starts with honest sizing and a fixed written price, and the work below covers the full range, from the first assessment through to the final commissioning test on the day.
Sizing and selection
Every continuous flow unit is sized honestly against the winter-morning peak, counting the bathrooms, judging how many showers genuinely overlap when a busy family household runs late, and matching a flow rate that holds steady at every tap, every time.
Electric without gas
Homes without a gas connection can still go continuous, because modern high capacity electric continuous flow models hang on the same wall brackets and run hard, though supply capacity is checked and quoted honestly before any promise gets made here.
Gas lines and flues
A property with gas already connected needs a correctly sized line, a compliant flue run and a tempering valve at the outlets, and our quote covers all three rather than discovering them as extras on the installation day itself.
Cylinder to wall
Swapping a tired storage cylinder for a wall mounted unit frees the ground space it occupied, ends the pilot light burning all day, and suits single bathroom family homes where nobody wants to wait between a shower and the dishes.
Servicing existing units
Existing continuous systems get a full descale, inlet filter clean and temperature stability test, because scale build up and ignored error codes shorten the life of a unit that should otherwise deliver hot water reliably for well over a decade.
What this climate does for a wall mounted unit
- A sheltered river setting Low salt exposure and mild winters compared with open harbour districts mean outdoor mounted units, the standard choice here for access and flue reasons, avoid the corrosion that punishes them elsewhere.
- Sized to the household, not the weather Mild winters shift the sizing question toward the genuine morning peak of a family home rather than worst case cold snaps these leafy streets rarely see.
- Renovation timing Steady rebuilding across the postwar stock means many installs land alongside bathroom or kitchen projects, which is the easiest moment to relocate a unit or run a new gas line properly.
Common problems with continuous flow systems
Most faults announce themselves early, and the same handful of causes covers nearly every call, so a proper diagnosis usually finds the answer on the first visit.
Temperature fluctuates mid-shower
A shower swinging hot and cold usually traces back to an undersized unit fighting simultaneous demand, an inlet filter clogged with scale, or a tired sensor, and a proper diagnosis identifies which before any parts get replaced unnecessarily.
Error codes and lockouts
Continuous units protect themselves by shutting down on ignition failure, flame loss or overheating, and while a reset sometimes restores service, repeated lockouts point to an internal fault that deserves a licensed diagnosis rather than another hopeful button press.
Weak flow, lukewarm taps
When flow drops to a trickle the flow sensor, the inlet filter or a partly closed isolation valve is usually responsible, and because these systems need minimum flow to fire at all, weak pressure quickly becomes no hot water.
When the fault sits in the unit rather than the supply, our hot water repair service handles the diagnosis and the fix.
Why the right system matters
Choosing and fitting a continuous flow unit properly pays off for decades, while doing it carelessly costs money every single day the system runs:
- Comfort that holds A correctly sized unit keeps every shower at temperature even when the household overlaps, instead of the mid-shower swings that come from guessing at flow rates.
- Running costs that drop No tank sheds standby warmth around the clock, so the energy bill reflects the hot water actually used rather than heat lost through the laundry wall.
- Space and safety recovered The rusty cylinder leaves the property, its footprint returns to the laundry, and the new unit's safety systems are commissioned and proven on the day.
Where a cylinder has reached the end of its life instead, hot water replacement covers the full swap.
How it works
Our process, step by step
- 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
Match the unit to the house
The continuous flow model is chosen against your household's genuine peak, the gas line, flue run and supply are checked against it, and the fixed price covers everything from removing the old system to commissioning the new one.
- 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 Riverview
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 Riverview 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
Suburbs we also cover
Continuous flow installations and repairs run across the suburb and into the neighbouring streets of Lane Cove, Longueville, Linley Point, Hunters Hill and Lane Cove West, with the same sizing discipline applied whether the house is a Federation original or a recent rebuild.
Good questions, straight answers
Questions Riverview households ask about instant hot water
Do instant hot water systems ever run out of hot water?
No, a correctly sized unit heats water the instant a tap turns on, so a long run of evening showers keeps going, though an undersized model can struggle to hold temperature under heavy demand.
Are continuous flow systems less expensive to run than a cylinder?
Generally yes, because nothing heats until a tap turns and no tank loses warmth all day, so energy use tends to fall compared with an old storage cylinder running standby losses around the clock.
Can an instant unit be fitted in a tight side passage?
Yes, most units hang on a narrow wall bracket and need far less room than a cylinder, which suits the tight side passages of the older brick homes around here.
Do continuous flow systems suit older brick houses?
They do, because a unit mounts on any sound brick wall, the flue run is short, and the old cylinder's footprint disappears, freeing space in a cramped interwar laundry or passage.
How long does a continuous flow installation take?
A straightforward like for like swap usually finishes within a day, while a change from cylinder to wall unit or from electric to gas takes longer because new pipe, flue or supply work is involved.
Are instant hot water systems gas or electric?
Both exist, gas models dominate where a line already runs, and high capacity electric units suit homes without gas, provided the household supply is checked and confirmed before the unit is promised.
