Endless hot water without the tank
An instant system heats water the moment a tap opens, so the shower queue never outruns the supply. This page explains how tankless units work, whether one suits your household, and how we install them properly.
Shaded blocks and cold mornings set the bar for tankless
The heavy tree canopy that defines this garden suburb keeps many properties shaded and cool right through winter, when long hot showers become a daily habit in period homes. A continuous flow unit copes with that pattern well, because it never depletes the way a storage tank can.
The honest trade-off is sizing.
A unit chosen too small for a double-brick house with two bathrooms will sag lukewarm on the coldest days, when inlet water arrives at its lowest temperature, so we calculate demand before recommending anything.
How we install instant systems
From assessment to commissioning, here is what a continuous flow installation involves:
Sizing and selection
We calculate your true peak demand, counting showers, taps and appliances that could run together, then recommend a gas or electric continuous flow model with the flow rate and temperature rise to match, so winter mornings stay comfortable throughout the house.
Gas supply upgrades
Continuous flow gas units need adequate gas capacity, and many pre-war and inter-war homes retain dated reticulated fittings exposed during renovation, so we upgrade regulators, meter capacity and supply lines to modern standards before hanging the new unit.
Clean changeover
The old tank is drained, disconnected and removed, the instant unit is mounted with new valves, flues and tempering where required, and the water and gas connections are pressure tested before the system is commissioned properly.
Settings and handover
We set the delivery temperature to a safe level, walk you through the controllers, explain the error codes worth watching for, and leave you with compliance certificates plus the reassurance of our Lifetime Labour Warranty on the workmanship.
Where new units meet old housing stock
Apartment blocks rising near the railway and the Pacific Highway increasingly specify wall-mounted continuous flow units, while the Federation and Californian Bungalow homes on the suburb's garden allotments are converting from tired storage tanks, well past their service life, to tankless systems that reclaim laundry and verandah space.
- Heritage constraints Conservation areas limit where flues and external units can sit, so placement is planned before quoting, not improvised on install day.
- Solid walls Double-brick construction needs the right fixings and penetration points, which we confirm against the building rather than assuming.
- Established gardens Gas runs are routed carefully around mature root systems and protected front gardens rather than trenched on instinct.
We plan each install around those constraints first, so the fixed price covers the whole job, including anything the walls or pipework reveal once work starts.
Problems we fix on instant systems
Continuous flow units fail in recognisable ways, and most respond well to early attention:
Lukewarm or fluctuating temperatures
Scale building on the heat exchanger or a failing flow sensor causes temperatures to swing or sag, especially in winter, and a descale or sensor replacement usually restores full performance without any need to replace the unit itself.
Error codes and lockouts
Modern units display fault codes when ignition, gas supply or venting misbehaves, and because some causes trace back to gas capacity or dated fittings rather than the appliance, we diagnose the whole installation before condemning any component.
Undersized units running flat out
A unit stretched beyond its flow rate delivers that familiar disappointing trickle of warm water when several outlets run together, which we resolve either by recalculating and upsizing the unit or by managing outlet demand honestly.
Why it matters to get it right
- Comfort that survives winter A properly sized and commissioned unit holds steady temperature through the cold months, when shaded period homes demand the most from their hot water.
- Space and efficiency gained Removing a tired storage tank frees floor area and stops the constant reheating losses, and pairing the changeover with a hot water repair assessment of other components avoids repeat call outs.
- Compliance and safety Gas changeovers in older housing stock touch regulators, flues and fittings that must meet current standards, and our licensed work keeps every certificate and warranty condition intact.
How it works
How the job runs, 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
Install and commission the unit
We size the continuous flow system against your household's real peak demand, upgrade the gas supply where the installation requires it, mount and connect the unit, then test temperatures, flows and safety devices before demonstrating the controls to you.

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 Killara
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 Killara 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 a tankless unit turns out to be the wrong call for your household, our gas hot water systems and electric hot water systems pages cover the storage paths, and the hot water hub ties the whole range together.
Where we work
Areas we service
We cover the whole surrounding district, from Gordon and Pymble down the line to Lindfield and Roseville, east into East Killara's larger blocks, bringing the same stocked vans, fixed written pricing and lifetime-backed workmanship to every job regardless of which side of the highway we're working.
Good questions, straight answers
Instant hot water systems: questions from the locals
How does an instant hot water system work?
Cold water passes through a heat exchanger inside a wall-mounted unit, where a gas burner or electric element heats it only as you draw it, so the supply never runs out and no storage tank sits losing heat overnight.
Can an instant system keep up with several showers at once?
It can, provided the unit is sized correctly for your peak demand, so we calculate flow rates across bathrooms and appliances before recommending a model rather than guessing and leaving you with lukewarm mornings.
Do instant systems cost less to run than a storage tank?
Usually, because there is no tank reheating water you are not using, though the real saving depends on fuel type, household size and tariffs, which is why we walk through running costs honestly before you commit.
Will an instant unit suit an older Federation home?
Very well. Wall-mounted continuous flow units free up floor space in laundries and verandahs, and upgrading dated gas fittings during the changeover is straightforward for a licensed plumber working on period housing.
What maintenance does an instant hot water system need?
A service every year or two covers descaling the heat exchanger, checking filters, valves and flues, and confirming temperature settings, which keeps warranty conditions intact and catches small faults before they leave you cold.
Do instant systems fail suddenly or give warning first?
Most give warning: fluctuating temperatures, error codes, slower delivery or lukewarm water point to scale build-up or a failing sensor, and an early repair visit usually costs far less than an emergency replacement call.
