Endless hot water, sized for the house that uses it
A continuous flow unit heats water as it flows past the heat exchanger, so nobody in the house waits for a tank to recover. For large older homes running several bathrooms, that single difference changes winter mornings entirely.

How we help with instant systems
Sizing and unit selection
Your household's genuine peak draw across simultaneous outlets is measured and compared against gas and electric models, then we recommend a continuous flow unit sized for the coldest morning of the year rather than a brochure average.
Installation and changeover
Old tanks are drained and removed, wall-mounted units go in their place, and gas and water connections are upgraded where corroded or undersized lines would throttle the new system, with every installation commissioned and tested on site.
Error codes and faults, traced properly
Ignition failures and temperature swings are traced with proper test gear rather than repeated resets, and most faults are resolved on the first visit because the van carries the common continuous flow parts.
Servicing and descaling
Annual servicing keeps heat exchangers clear of scale, inlet filters clean and combustion tuned, work that meaningfully extends a unit's working life in households running multiple bathrooms through long winters on the ridge.
The cold-morning test this suburb hands every system
- Sizing for the worst morning This ridge runs noticeably cooler than coastal Sydney, and an undersized unit shows its limits exactly then, dropping the shower to lukewarm the moment a dishwasher starts, so we size for simultaneous outlets from day one.
- Commissioning on site Temperature and flow settings are set in the house, not at the factory default, so the whole system delivers steady water at once.
- Households that peak together Older families in owner-occupied homes tend to run bathrooms at the same hour, and the unit we recommend accounts for that pattern honestly.
Common instant hot water problems
Temperature swings mid-shower
Fluctuating temperature usually traces to an undersized unit, a tired flow sensor or a restrictor issue, and because these faults compound on cold mornings when demand peaks, a proper diagnosis beats another frustrating shower every time.
Error codes and lockouts
Ignition failures, gas supply problems and control faults trigger shutdown codes that a reset only silences temporarily, so we test the supply, the ignition components and the sensors properly and fix the actual cause.
Weak hot water flow
Scale in the heat exchanger, a clogged inlet filter or throttling old supply lines restricts output, a pattern familiar in homes where galvanised pipework has never been updated to match a modern unit.
Why it matters
- Comfort that holds under load A correctly sized unit means the third shower and the dishwasher coexist, which decides whether winter mornings run smoothly in a full house.
- Running costs without standing losses Continuous flow heats only what you use, so the standing losses of an ageing tank disappear from the quarterly bill.
- Space back, quietly banked Reclaiming the cylinder's footprint and modernising the plant is an upgrade felt daily and recognised again at sale.
How it works
The process, start to finish
- 01
Call and tell us
Ring (02) 9072 0520 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
Fit and commission
We confirm gas capacity and supply condition, mount the unit, upgrade connections where they throttle performance, then set temperature and flow parameters in the house and walk you through the controls until they make sense.
- 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 Cheltenham
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 Cheltenham 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.
Continuous flow is one of three paths, not the only one. Our gas hot water systems and electric hot water systems pages compare storage options honestly, while hot water installation covers new positions and renovation rough-ins, and the hot water hub holds the full picture.
Areas we service
Beyond this enclave
Wherever the house sits
If the existing unit is worth saving, hot water repair handles valves, sensors and ignition faults, and hot water replacement covers end-of-life changeovers when the fix-it conversation has run its course. Cold taps right now are a different job entirely: our no hot water page opens with what to do first.
Good questions, straight answers
Instant hot water systems questions Cheltenham locals ask
Will an instant system run out of hot water?
No, because continuous flow units heat water as it passes through rather than storing it, so the last shower on a cold winter morning runs just as hot as the first.
Do instant systems suit older heritage homes?
Yes, though some period homes need supply upgrades first, because corroded or undersized lines and ageing gas runs can throttle a continuous flow unit, and we check all of that before quoting.
How long does an installation take?
Most changeovers are completed in a single visit, and you receive a fixed written price before any work begins, so both the timing and the cost are settled before we start.
Are instant systems gas or electric?
Most continuous flow units run on natural gas, which suits the connections around the ridge, while electric models suit homes without gas and smaller households with lighter hot water demands.
What size unit does a large house need?
Sizing comes down to simultaneous outlets rather than tank capacity, so a home with two or three bathrooms running at once needs a higher flow rate, which we calculate properly.
Is the work guaranteed?
Every installation is backed by our Lifetime Labour Warranty, so if anything in our workmanship is not right, we come back and correct it with no questions and no cost.
