Endless Hot Water, Sized Properly the First Time
A tank heats, stores and eventually runs out. An instant system heats only what flows through it, when it flows, so the shower never cools because someone ran the dishwasher. Speak to the team on (02) 9072 0504 and we will tell you honestly whether continuous flow suits your house, your fuel and your family's morning habits.
Why This Ridge Changes the Specification
At roughly 171 metres above sea level, this elevated pocket of Ku-ring-gai runs noticeably cooler through winter than coastal Sydney. Cold inlet water is the single biggest factor in how a continuous flow unit performs, and a model that feels generous in September can fall short on a July morning.
Sized for the coldest day, not the average one
Honest sizing beats a fast sale
How We Install and Look After Continuous Flow
- Right-sized flow for the house We start with the household itself, counting bathrooms, laundries and kitchens that could run together, then specify a unit whose litre-per-minute rating matches real demand exactly, so nobody endures a cold finish when two showers run at once.
- Gas conversions handled end to end Switching from an old electric tank to gas instant means gas run sizing, flue placement and an upgrade of the meter, and we manage the whole changeover, leaving you with endless hot water and lower running costs.
- Fits where tanks cannot Compact wall-hung units free up the laundry or external wall space a bulky cylinder consumes, a real advantage on the generous lots around here where garages and storerooms earn their keep, and we mount and flue every installation to standard.
- Temperature stability, proven on site Modulating controls hold delivery temperature steady even when winter inlet water drops sharply, and we commission every unit properly, so the shower on a frosty ridge-top morning feels identical to one in a coastal bungalow.

Big Houses, Busy Mornings, Simultaneous Demand
The housing here skews large: detached double-brick and brick-veneer family homes on generous lots, many with three or four bedrooms and more than one bathroom. That is exactly the usage pattern continuous flow either handles brilliantly or badly, depending entirely on the sizing.
Where the demand stacks up
The commuter window
When an Instant System Misbehaves
Two showers, temperature swings
Two showers running usually see the further outlet swing hot and cold because an undersized unit cannot modulate fast enough across simultaneous household demand, and replacing it with correctly rated capacity restores calm, consistent water to every tap in the home.
Ignition lockouts and error codes
A unit that shuts down with a fault code usually has a blocked burner, a tired ignition assembly or an interrupted gas supply, and working through those in sequence on site restores hot water without guesswork or unnecessary parts.
Lukewarm water at distant outlets
Water arriving only faintly warm at a far bathroom usually reflects a long pipe run losing heat on the way, and a tempering valve set correctly, insulation added or a unit re-sited fixes it properly rather than temporarily.
Where the fault points to the unit itself rather than the format, our hot water repair team diagnoses before recommending anything, and a sudden total failure with no warning is covered on our no hot water emergency page.
Why Acting Early Pays Off
- Comfort you stop noticing A correctly specified system disappears into daily life, while an undersized one turns every school morning into a negotiation over shower order.
- Running costs that head down Instantaneous units heat only what you use, so households replacing a tired electric tank typically see energy waste fall from the first quarter.
- No repeat failures Units pushed past service life fail suddenly, and an assessment while the old system still works lets you plan the changeover on your terms, not the tank's.
How it works
Our Installation Process, Step by Step
- 01
Call and tell us
Ring (02) 9072 0504 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, commission and prove
On continuous flow jobs this is the commissioning stage: your plumber mounts and flues the unit, checks gas and water sizing, purges the lines, sets the delivery temperature and then tests every outlet so the whole system is proven working.
- 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 St Ives
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 Ives 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 your existing tank is simply at the end of its life, our hot water replacement page covers the changeover decision in detail.

Where Else We Work Around the North Shore
This page sits within a service area stretching across Ku-ring-gai's leafy ridgeline, taking in Pymble, Gordon, St Ives Chase, Turramurra and Belrose. The same licensed team, the same fixed written pricing and the same lifetime workmanship guarantee apply across that patch.
Good questions, straight answers
Hot Water Questions St Ives Households Ask
How long does an instant hot water system last?
Most quality continuous flow units serve fifteen years or more with periodic servicing, and because established family homes here often run hot water gear past its service life, an early check prevents a cold-shower surprise.
Can one unit supply two showers at once?
It depends on the litre-per-minute rating and your winter inlet temperature, which is why we calculate simultaneous demand across bathrooms and laundries first, then specify a model that holds temperature even when the household peaks.
Is converting from an electric tank to gas worth it?
For homes with gas available it often is, because instantaneous units avoid standby losses and warm only the water passing through, and we assess your meter, run and usage pattern honestly before recommending the switch.
Do continuous flow systems cope with cold winter mornings?
Yes. We size units against winter inlet temperatures, and because this elevated ridge runs cooler than coastal Sydney, the specification accounts for the coldest morning of the year rather than a mild annual average.
What does a new instant system cost?
Every job is priced as a fixed written quote after the site inspection, covering the unit, install and commissioning, with a $0 call out fee, so the number you approve is the number you pay.
Are your installers licensed?
Every plumber holds full licensing and insurance, each job is backed by our Lifetime Labour Warranty, and compliance paperwork arrives with the invoice, so the installation protects both your household and your property records.
