A real person answers, day or night
How much of that cupboard is really about the tank?
Ring (02) 9072 0597 and tell a plumber how many taps actually need to run hot water at once, and get an honest read on whether going tankless suits this particular household or simply sounds appealing.
Rinsing off after the beach or a round of golf
Between the surf club crowds off Collaroy Beach and golfers finishing a round at Long Reef, plenty of households here run back-to-back hot rinses at times a standard tank was never built to handle.
- Peak demand here follows the tide and the weather, not the clock A sudden run on hot water after a good surf session looks nothing like the steady, predictable pattern a tank is sized around.
- Continuous-flow simply doesn't care about timing Whether several showers happen close together or spread across the afternoon, the unit responds to whatever's actually open at that moment.
Matching the unit to the outlets it serves
Outlet count, not the tank it's replacing, is what actually decides which of these four instant configurations suits a property's hot water needs:
One Tap, One Unit
Positioned right beside the one fixture it feeds, a single-point unit skips the pipe run a full system would need, making it the practical answer for a converted garage, a distant outdoor tap or a small addition on its own.
Covering The Whole House
One larger unit positioned centrally can serve every bathroom under a single roof, its capacity worked out against genuinely simultaneous use rather than a rough estimate, so the household downstream never notices anyone else running the tap first.
Doubling Up For Big Households
Where three or more outlets regularly draw together, pairing two units spreads that load evenly, so neither pressure nor heat drops off the way a single unit pushed well past its rating eventually would.
Choosing Gas Or Electric
Multiple bathrooms drawing at once generally push the recommendation toward gas for its stronger simultaneous output, while a single standalone tap is usually better matched to electric, sparing the cost of a fresh gas line for one fixture.
New apartments are rewriting the laundry
Newer unit blocks built since the early 2000s, especially those replacing older buildings damaged by past coastal storms, are increasingly designed around compact laundries that were never meant to fit a full-size cylinder.
- A wall-hung unit solves a design problem, not just a plumbing one Developers planning these smaller floor plans now specify the space for an instant unit from the outset rather than squeezing one in afterward.
- The school run adds its own pressure point Households near Narrabeen Lakes Public School juggling several showers before the same bell benefit from a unit that keeps pace with back-to-back demand rather than making someone wait their turn.
Two sizing issues behind most calls
Struggles Once It's Cold
Winter changes the maths for any instant unit, since incoming water starts noticeably colder and the unit works harder to lift it to a comfortable temperature, with a marginal unit showing the effort first, ahead of anything correctly rated.
Two Taps, One Loser
When two taps run together and one clearly comes off worse for pressure or heat, the fitted unit almost certainly wasn't rated for that overlap, and moving up to a bigger or paired setup resolves it for good.
Why sizing matters more without a tank in reserve
Sizing matters more with an instant system than with almost any tank, because there's no reserve to paper over a mistake and any shortfall shows up the moment a second tap opens:
- Undersized isn't a one-off annoyance, it's a daily one A unit already working flat out for a single shower simply has nothing left in reserve for whatever runs after it, and that shortfall repeats every single morning rather than every so often.
- Getting the size right the first time avoids paying for the retrofit twice Fitting new pipework for an instant unit is enough work that nobody wants to redo it a year later because the first one was quietly undersized.
- Oversized draw doesn't just disappoint, it can shut things down Pushed well beyond its rated flow, a unit trips its own safety limiter rather than delivering hot water, protecting itself from a sizing decision rather than genuinely malfunctioning.
How it works
How an instant hot water job runs, step by step
- 01
Call and tell us
Ring (02) 9072 0597 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
Wall-mount and prove it
The wall position gets confirmed first, then the unit is connected to gas or power alongside the existing pipework, flow and temperature limits set correctly, and every outlet it serves opened together to prove the sizing holds.

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 Collaroy
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 Collaroy 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.
An instant unit sized properly the first time is one job this crew genuinely prefers getting right at the quote stage, since there's no tank to quietly cover for a guess.
Where we work
Areas we service
Instant fit-outs and servicing reach Narrabeen, Collaroy Plateau, Dee Why, Cromer and Wheeler Heights too, and the same outlet-count-first approach applies whether the job's a tight laundry retrofit or a full house serving several bathrooms.
Good questions, straight answers
Instant hot water questions from Collaroy, answered
Does the after-surf or after-golf rush actually strain these units?
It can with an undersized setup, since several showers landing close together tests an instant unit harder than the same household's normal spread-out routine, which is exactly the peak this crew sizes for upfront.
What moves the price on fitting an instant system?
Fuel type, the unit's rated flow and the count of outlets it must serve between them decide the figure, and a plumber only confirms it after actually walking through the property.
Could one instant unit genuinely run a whole three-bathroom house?
Rarely without strain, because a unit sized for a single bathroom is quickly overwhelmed once a second bathroom starts drawing too, so the honest fix is counting real outlets rather than assuming the old tank's coverage carries over.
Are the trades connecting gas or power to these units properly certified?
Yes, that specific fuel or power hookup needs a qualification beyond a general plumbing ticket, and everyone on this team already carries it, so nothing waits on a second tradesperson.
Does a first-time instant install carry any less protection than a callout?
No, the Lifetime Labour Warranty covers a brand-new instant fit-out to the same unconditional standard as every other job on the books, so a genuine fault in the work later costs the household nothing.
Does swapping from a tank make sense in an older Pittwater Road unit?
Often, yes, since a wall-hung unit clears almost all the floor space a cylinder would claim, which is precisely why it suits the tighter service areas common in older blocks along that strip.
