Endless hot water from a box the size of a suitcase
A tank holds a fixed volume; a continuous flow unit heats water the moment it moves through the heat exchanger, so the supply lasts as long as the tap stays open.
That single difference changes how a household lives, and it is why these units have become the conversion of choice in the suburb's smaller dwellings.
- Compact by design A wall-mounted unit frees the cupboard a tank would swallow, a genuine gain in flats built to 1930s floorplates.
- Heated only when used No standing losses, no running dry mid-shower because someone filled the bath first.
- Compliance sorted Our licence (#275278C) covers the certificates your landlord or strata manager will ask for.
Instant hot water services we cover
Every job below starts with a proper assessment of the building, the existing services and your household's usage, because a continuous flow unit only performs well when it is sized, mounted and commissioned correctly. For the wider picture on tanks, repairs and system choice, the hot water hub pulls the whole silo together.
New continuous flow installations
We mount and commission instant systems sized to your household's simultaneous outlets, checking gas capacity, flue paths and water pressure first, so the unit you get delivers the temperature and flow the bathroom and kitchen actually demand together.
Converting from a storage tank
Swapping a tank for an instant system changes the pipework, the power or gas supply and often the location, and we manage that whole conversion, capping the old connections and leaving the freed-up cupboard ready to use again. If the existing unit is worth saving rather than replacing, hot water repair covers the fix-first path.
Fault finding and servicing
Ignition failures, error codes, scale in the heat exchanger and flow sensors that drift all respond to proper diagnosis, and we service quality continuous flow units wherever the parts remain available rather than defaulting to replacement.
Units matched to the building
Not every instant system suits every wall, and units near the harbour face salt-laden wind that corrodes external hardware years early, so we specify models and mounting positions built to survive the exposure your particular address copes with.
Renting, strata and the harbour edge
Most households here rent, which shapes the job as much as the plumbing does. Tenants need the fault documented and quoted for the landlord's approval, and agents need invoices that make sense without a follow-up call.

Position on the peninsula
Common problems with instant systems here
Lukewarm water when two outlets run
A unit undersized for the household's simultaneous demand cannot hold temperature when a shower and a dishwasher run together, a pattern common in converted flats, and correct sizing against real usage fixes it permanently.
Error codes after years of salt exposure
Continuous flow units mounted on external walls near the water breathe salt-laden air, which corrodes connectors and sensors well ahead of inland expectations, and we replace affected parts with hardware suited to coastal installation.
Old gas connections struggling to cope
Pre-1940 terraces and early walk-up blocks often retain dated gas pipework, and a new continuous flow unit's higher draw can expose undersized runs, so we inspect and upgrade the supply before the appliance goes on the wall. Suspected gas faults are urgent, and gas leaks sets out what to do immediately.
Why choosing the right system matters
Getting this decision right pays back every single day you live in the home, and getting it wrong means paying twice.
- Endless supply, no rationing A household that has lived under a tank's limits stops planning showers around each other, and guests stop getting the cold tail-end of a depleted cylinder.
- Lower running costs over time Continuous flow units heat only what you use, so the standing losses of a constantly reheated tank disappear from the bill, which adds up across a year of warm Sydney summers and mild winters.
- Space returned to the household Removing a tank from a cupboard or laundry alcove returns genuinely useful storage to an apartment that has never had any to spare, room for linen, luggage or a vacuum in homes where every square metre counts.
How it works
How a new instant system gets installed
- 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
Size, mount and commission the unit
We assess your household's true simultaneous demand against the available gas or power capacity, inspect the wall, flue path and access, then hang and connect the unit with compliant valves and commission it to hold temperature at every tap before we hand it over.
- 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 Kirribilli
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 Kirribilli 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.
Straight after a job near the ferry wharves or a quiet residential conversion, the standards are identical, and our residential plumbing page explains how the broader work fits together.
Where we work
Areas we service
Instant hot water work reaches across the harbour peninsula into Milsons Point, Lavender Bay, Kurraba Point, McMahons Point and Cremorne Point, with the same fixed pricing and continuous flow expertise carried to every address, whether the building is a Federation terrace or a 1960s walk-up.
Good questions, straight answers
Instant hot water questions Kirribilli locals ask
Can an instant system be fitted inside a local apartment?
Yes, provided gas and fluing or suitable power capacity exist, and we assess the cupboard, ventilation and access first before quoting a fixed price for the complete installation.
How long do continuous flow units last in salt air?
Quality units typically serve fifteen to twenty years, though harbourside exposure shortens that for externally mounted hardware, so we specify corrosion-resistant models and mounting positions.
Do instant systems really never run out of hot water?
Correct, they heat water as it flows rather than storing it, so supply continues as long as the unit's flow rate matches how many outlets you run at once.
Is a fixed temperature setting safe for children?
Yes, continuous flow units hold a precise set temperature, which removes the scald risk stored tanks carry, though tempering valves are still fitted where regulations require them.
Do you service continuous flow units too?
We do, covering failed sensors, ignition faults, scale build-up and flow errors, and we will tell you honestly when fixing beats replacing on an ageing unit.
Will a new instant system need council or Sydney Water approval?
Most like-for-like swaps do not, but switches involving new gas runs, fluing or meter upgrades are handled and certified by us as part of the quoted job. --- Related reading: how instant compares on gas hot water systems, what electric hot water systems offer where gas is not connected, and when hot water replacement is the better end-of-life call.
