Endless hot water without a bulky tank taking up valuable floor space
Continuous flow systems heat water the moment it moves through the exchanger, so the last shower of the morning runs as hot as the first. No cupboard or balcony surrenders its floor to a storage tank, which is exactly the trade locals want to make.
That is what we deliver across St Leonards and the streets around it, day and night. Call (02) 9072 0528 and talk to a plumber who works these buildings every week.

What we do with continuous flow
From tank-to-instant conversions to descaling a temperamental exchanger, these are the jobs we carry out on continuous flow systems across the local towers and cottages, each finished with testing, temperature setting and a fixed written quote:
Instant system conversions
Converting from an old electric tank to a continuous flow unit frees up the laundry cupboard or balcony wall, and we size the flow rate to match every outlet running at once across your household on a typically busy morning.
Gas continuous flow
Gas units deliver the strongest flow for the least running cost where a gas main or bottle bank already exists, and we check your meter capacity and flue route before quoting rather than discovering a costly problem on installation day.
Electric continuous flow
Electric instant units suit apartments without gas and without external flue options, mounting compactly on a wall inside the bathroom or cupboard, though we verify your power supply and cabling can honestly and safely carry the load before recommending one.
Servicing and descaling
Continuous flow units in hard-water areas scale up their heat exchangers over the years, so a periodic flush and service keeps temperature steady and preserves the manufacturer warranty, which beats an early replacement by a wide margin every single time.
Where a unit has simply failed outright and repair is no longer sensible, our hot water repair team handles the diagnostic work that decides the question.

Common problems we fix
Temperature swings
Water lurching between hot and cold while someone runs a tap elsewhere usually means the unit is undersized for genuine simultaneous demand, and a flow-rate check against your household's real usage tells us quickly whether a bigger unit is warranted.
Fault codes and ignition failures
Modern units flash fault codes when ignition fails, the gas supply starves or a sensor drifts out of range, and we carry diagnostic gear and common parts on the van so most codes are usually resolved on the first visit.
Cold water sandwich
That burst of lukewarm water between two hot spells is a classic continuous-flow quirk as the heat exchanger pauses briefly between draws, and a small recirculation loop or tempering adjustment usually tames it entirely without replacing a healthy unit.
If the fault turns out to be the gas supply itself rather than the unit, stop and read our gas leaks guidance first, because that situation should never wait for a scheduled appointment.
Why upgrading before the old tank dies pays off
Choosing continuous flow is not only about endless showers; the decision shapes running costs, space and how the household copes when everyone wants hot water at once, and these are the outcomes worth weighing:
Nobody draws the short straw anymore
A correctly sized instant unit keeps temperature stable no matter how many outlets run at once, so the person showering second gets the same comfort as the person who got up first.
Running costs follow actual use
The system burns energy only while water flows, which suits busy households that shower at scattered times, and gas models in particular undercut old electric storage over a year.
You reclaim the space
Removing a tank from a cupboard, balcony or laundry corner returns genuinely usable floor area to a compact apartment, and wall-mounted units sit tidily where a cylinder never could.
How it works
How the installation process runs, step by step
A clear sequence, a fixed price and no surprises. That is how every job runs, from the first phone call to the final temperature test.

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.

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, fit and commission
We match the unit's litres-per-minute rating to the showers, taps and appliances your household genuinely runs together, confirm the gas and power supply behind it, then mount, connect and commission the system with output temperature set where you will actually use it.

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 St Leonards
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 St Leonards 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.
Homeowners weighing tankless against a conventional cylinder will find the full comparison on our gas hot water systems and electric hot water systems pages, and fresh installs or relocations belong with hot water installation.
Where we work
Where else we turn up
Our crews cover the whole lower North Shore patch around this site, including Crows Nest, Wollstonecraft, Naremburn, Artarmon and Greenwich, bringing stocked vans and the same fixed-price approach to every street, whether the job sits in a tower or a cottage.
Good questions, straight answers
Instant hot water questions locals ask us
How long does an instant hot water system last?
A quality continuous flow unit typically serves fifteen to twenty years with periodic servicing, and because the heat exchanger is the main wearing part, flushing it regularly extends that span considerably.
Can you install instant systems in local apartments?
Yes, compact wall-mounted units suit the local towers well, and we coordinate building-manager access, confirm riser isolation and verify power and gas capacity properly before quoting the fixed written price.
Are instant systems less expensive to run?
Gas continuous flow units usually cost less to run than electric storage because they heat only on demand, while electric instant units suit homes without gas but draw heavily while operating.
Do older gas lines cope with a continuous flow unit?
The pre-1940 cottages on the southern streets often carry original gas fittings, so we assess supply capacity and upgrade the run to current standards where needed before connecting the new unit.
What size instant system does a family need?
Sizing comes down to outlets running at once rather than household storage, so we calculate the litres per minute your showers and taps demand together, then match a unit accordingly.
Do instant units need servicing?
An annual or biennial service flushing the heat exchanger prevents scale buildup, holds output temperature where you set it and keeps the manufacturer warranty intact, costing far less than replacing the whole unit early.
