A real person answers, day or night
Thinking about an instant hot water system? Here is when it shines
Because a continuous-flow unit fixes to the wall and stores nothing, it suits small homes that value every spare corner and households that hate running out mid-shower. Call (02) 9072 0502.
Where continuous flow suits the newer blocks
Compact living near the station
Small courtyards, endless showers
What choosing instant involves
Every continuous-flow recommendation turns on the flow you need, the fuel available and the winter temperature rise, so the unit you choose keeps up on the coldest, busiest morning of the year:
Matching the flow
Because a tankless unit is capped by its flow rate not a stored volume, we tally the showers and taps that may open at once and choose a unit that holds heat across the lot without thinning to a dribble.
Gas or electric
Continuous-flow units are sold in gas and electric versions, so on a home with gas we lean that way for stronger winter flow, while an all-electric model can serve a compact flat, and we weigh the two against your supply.
Winter temperature rise
A continuous-flow unit has to lift cold winter mains water to shower heat in one pass, so we size for the coldest months rather than a mild day, so winter flow you rely on holds firm rather than collapsing mid-shower.
Wall-hung placement
Because the unit sits on a wall bracket and vents outward, we plan the mounting and clearances early, so on a tight terrace or a strata cupboard the new heater lands cleanly without stealing the room a tank once claimed.
Continuous flow is not for every home
Heavy simultaneous demand tests it
Older supply and gas need checking
What to weigh before you commit
Not enough flow
When a single continuous-flow unit is asked to feed more outlets than its litres-per-minute rating allows, the water thins and cools, so we size the unit to your true peak demand rather than the household you had a decade ago.
Cold-water sandwich
Some units send a brief slug of cooled water between draws as the burner cycles, a quirk called the cold-water sandwich, which the right model and a small buffer largely tame, and we flag it honestly before you buy.
Retrofit surprises
Dropping a continuous-flow unit into a home built around a storage tank can expose an undersized gas line or a tight vent path, so we survey the site first, sparing you a half-finished job stalled at the wall.
Why choosing instant carefully matters
A continuous-flow system chosen to match your home is a quiet pleasure, while one picked on the brochure alone disappoints on the very morning you need it:
Hot water with no end
Floor space handed back
A unit that copes in winter
How it works
How an instant changeover runs, step by step
- 01
Call and tell us
Ring (02) 9072 0502 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.

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
On the wall, commissioned
We fix the unit to the wall, run the water and fuel connections plus any flue it needs, pressure-test the joints, then dial in the temperature and check the flow holds steady across the outlets you use most together.

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 Arncliffe
For a continuous-flow choice, this is what stands behind the plan.
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 Arncliffe 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
Areas we service
Further afield, we plan and fit continuous-flow systems for Wolli Creek, Banksia, Rockdale, Turrella and Kogarah, sizing each unit to the home's peak flow so the endless supply holds up in the tightest flat and the busiest house alike.
Good questions, straight answers
Instant hot water questions Arncliffe locals ask
Does instant hot water ever run out?
A rightly sized continuous-flow unit heats while the tap stays open, so it will not empty like a tank does, though every model carries a flow limit worth matching to your use.
Does a continuous-flow unit really save space?
Yes, it fixes to a wall and holds no water, so it clears the cupboard or nook a storage tank would otherwise fill, which matters most in a small flat.
Is instant better in gas or electric?
Where a gas main is present, gas continuous-flow usually gives stronger winter flow, while a small all-electric unit fits a compact flat, so we weigh both against your supply.
Will an instant system keep up in winter?
It will when it is matched to the coldest winter mains, which is why we size for July not a mild spring day, so the flow stays hot when the inflow is icy.
Can a continuous-flow unit feed a big household?
A large home with several outlets open at once might step up to a bigger unit, or add a second heater, so we match the flow rating to your genuine peak before recommending anything.
How is an instant installation signed off?
The finished unit is tested under pressure, commissioned and lodged under licence #275278C, and the compliance certificate reaches you with the invoice once the work wraps up.
