Hot Water Without the Tank, Fitted Properly
A continuous flow unit heats water only as it flows, so no tank steals a cupboard and nobody loses a shower to a filled bath. It suits high-density living, and our crew sizes every unit to the household that will use it.
If you are weighing up every option, our Crows Nest home page gives the full picture across all four plumbing categories.
What Makes Instant Systems Different Around the Village
The suburb's housing stock explains why tankless units keep winning here. Units and apartments dominate the dwelling mix, and that share has only grown since the 2024 Metro station brought a wave of new towers with it.
- The laundry cupboard is prime real estate In a walk-up flat or a one-bedroom near the Willoughby Road strip, a wall-mounted continuous flow unit hands that cupboard back entirely.
- Older terraces add a supply-side wrinkle Many retain legacy gas fittings from decades past, so the supply needs checking before any instant gas unit connects, not after.
What We Handle on an Instant System Job
From first assessment to commissioned unit, our crews cover the full life of a continuous flow system, and every job starts with a $0 call out and a fixed written quote.
Continuous flow installation
New instant systems need correct sizing, compliant connections and careful commissioning, so your plumber calculates peak demand, confirms the available services, then fits and tests the unit so every outlet delivers steady hot water.
Gas instant units
Gas continuous flow units suit homes with an existing connection, and because pre-war terraces around here often carry legacy pipework, your plumber checks and upgrades fittings where needed before the new unit ever lights.
Electric instant units
All-electric apartments are the natural home for electric instant units, and your plumber confirms the power supply can carry the load before recommending a model, because an undersized supply turns a good unit into a frustrating one.
Tank to instant
Retiring a tired tank in favour of continuous flow frees floor space and ends standing losses, and your plumber manages the changeover, capping old pipework and rerouting the supply cleanly to the new position.
Fault-finding and servicing
Instant systems fail differently from tanks, usually at valves, sensors or igniters, so your plumber diagnoses the specific fault, carries common parts in the van, and restores full flow on the first visit wherever possible.
For the wider hot water picture, our hot water hub covers every system type, and if a storage setup still suits you better, hot water replacement and hot water installation handle the tank side of things.
Cold Snaps and Compact Laundries: The Local Pattern
- Winter is when tired units surrender Hot water failures peak in cold snaps across the suburb's older housing stock, and a continuous flow unit that has limped through autumn often gives up on the first genuinely wintry morning.
- Summer exposes flow limits West-facing terraces and upper-floor flats cop the afternoon heat, households run longer cooler showers in January, and an undersized unit shows its capacity fast.
- Young professionals run demand in parallel In the dense unit stock, one shower going while the dishwasher cycles is the exact scenario an undersized instant unit handles badly and a correctly sized one handles without a flicker.
Common Problems We Fix
Temperature that swings hot and cold
Fluctuating output usually traces to a faulty sensor, a struggling igniter or a flow rate below the unit's minimum, so your plumber tests each cause in turn and restores steady temperature rather than replacing parts on guesswork.
Flow that drops across the house
Weak output at several outlets points to a clogged inlet filter, scale in the heat exchanger or an undersized unit, and your plumber identifies which before quoting, because the fix differs completely in each case.
Error codes and lockouts
Modern units display fault codes that narrow the diagnosis fast, so your plumber reads the code and tests the component it names.
If the whole unit has died and everyone is shivering, that is an urgent job, and our no hot water page covers the same-night response. For units worth saving rather than swapping, hot water repair handles tank and continuous flow faults alike.
Why It Matters: Getting the Sizing Right
- Comfort depends on correct sizing An undersized unit cannot hold temperature when two outlets run together, and no amount of fixing a valve cures a capacity problem, so the assessment stage matters more with instant systems than any other type.
- The gas supply must be up to the job Legacy fittings in the older terraces can starve a new unit, and connecting without checking risks poor performance and safety issues that a proper pre-installation inspection eliminates.
- A good unit rewards you for decades Fitted and commissioned properly, a continuous flow system outlasts most storage tanks, so the extra care at installation pays back every winter for fifteen years or more.
How it works
How We Fit Your System, Step by Step
- 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 and assess the supply
Your plumber matches the continuous flow unit to your household's peak demand, checks the available services can genuinely carry it, and confirms the mounting position and pipework run suit instant heating before anything is ordered or fitted.
- 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 Crows Nest
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 Crows Nest 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 hidden leak is undermining your water pressure, leak detection traces it properly before any system gets blamed.
Where we work
Areas We Service Beyond the Village
Our crews cover St Leonards, Wollstonecraft, Cammeray, Naremburn and North Sydney with the same stocked-van, fixed-price service, and the mix of Federation terraces, mid-century walk-ups and new apartment towers across those neighbouring suburbs means instant systems are a regular fit on jobs well beyond the ridge itself.
Good questions, straight answers
Hot Water Questions the Locals Ask
How long does an instant hot water system last?
A quality continuous flow unit typically serves fifteen to twenty years with periodic servicing, which is longer than most storage tanks, so many households replace their old tank with an instant system once and never look back.
Can an instant system run two showers at once?
Yes, provided the unit is sized for the household's peak flow rate, which is exactly what your plumber calculates during the quote, matching litres per minute to the number of outlets likely to run together.
Do instant systems work in apartments?
They suit apartments particularly well because they free the laundry cupboard entirely, and before fitting a wall-mounted unit your plumber checks the gas or power supply along with any strata requirements for the building.
Is gas or electric better for an instant system?
Gas continuous flow units deliver higher flow rates where a connection already exists, while electric units suit all-electric apartments, so the right answer depends on the services already running into your building.
How much does installation cost?
Every job is priced individually with a fixed written quote before any work begins, and the call out fee is $0, so you get an exact figure for your building without paying anything to find out.
Do instant hot water systems need servicing?
A periodic service keeps valves, filters and heat exchangers in good order and protects the warranty, and because the suburb's older terraces often carry legacy gas fittings, a check-up also confirms the supply line is sound.
