A real person answers, day or night
Endless hot showers without the tank
Instant systems heat water the moment you turn the tap, so the supply never runs cold halfway through a Sunday morning wash. Households across Greenwich call (02) 9072 0504 and we will size one for your home honestly.
Why continuous flow suits the peninsula
The local housing stock gives these units a natural advantage over bulky tanks, and the reasons sit in the buildings themselves.
- Tight spaces, big gain The interwar homes across the point tuck their plumbing into narrow side passages and under-stair cavities where a storage cylinder simply does not fit, so a wall-mounted unit the size of a small suitcase frees that space entirely.
- No idle tank cycling Because a continuous flow unit heats only what you draw, nothing sits in a cupboard cycling away overnight, which suits compact strata bathrooms and laundries near the Pacific Highway edge just as well.
- Shelter from the salt Harbourside air shortens the life of exposed tank jackets near the water, so a unit sited under an eave starts to look like the sensible choice.
What we install and service
This work covers more than bolting a unit to a wall, and these are the jobs we handle most weeks around the suburb.
Sizing and selection
We calculate your household's simultaneous demand, from morning showers to the dishwasher, then match a unit whose flow rate genuinely covers it, because an undersized system disappoints at exactly the worst moment each day.
Gas continuous flow
Where a gas line already serves the house, a gas instant unit delivers strong recovery at low running cost, and we handle the flue path, regulator checks and compliance tagging under our gas licence as part of the one fixed quote.
Electric continuous flow
Homes without gas get a properly rated electric unit, and because household supply capacity varies street to street, we confirm what your wiring can carry before recommending a model rather than after the safety cutouts start tripping.
Swapping a tired tank
Trading a failed storage cylinder for continuous flow frees the side passage or laundry cupboard it occupied, and we upgrade the pipework, valves and connections so the new unit performs as its manufacturer intended from day one.
Servicing and faults
Scale build-up, ignition faults and flow sensors all fail eventually, and most fixes are straightforward, so if your existing unit is sulking, see our hot water repair page before assuming it needs replacing.
The apartment and strata angle
Apartment dwellers form a real share of the suburb, and instant systems suit strata life in ways a tank cannot.
- One household's fault, one household's problem A unit on a balcony or in a laundry cupboard means no cylinder rupturing above a neighbour's ceiling, a risk we see regularly in older blocks toward St Leonards, where shared plant rooms still serve multiple units from ageing storage.
- Committee-friendly upgrades Owners corporations increasingly favour individual continuous flow units during upgrades precisely because a failure then affects one home rather than half a floor.
- Coordination included Working that swap through your strata committee, from connection upgrades to flue clearances, is routine for us, and it arrives on the same fixed written quote as any house job.
Common problems we fix
Continuous flow systems have their own habits, and these are the complaints that bring peninsula households to call us.
Temperature fluctuating mid-shower
An undersized unit, a clogged inlet filter or a failing flow sensor causes the hot water to surge hot and cold, and we trace which culprit applies, then correct it, usually without replacing the system at all.
Unit cutting out under load
When a second tap shuts the first one down, the flow rate no longer matches the household's demand, so we measure real usage and either retune the unit or recommend an honest upgrade to the right capacity.
Error codes and no ignition
Modern units display fault codes that point to ignition, gas supply or sensor faults, and because many of these are fixable, check our hot water hub before you order a replacement nobody needs yet.
Why acting early matters
Continuous flow faults rarely fix themselves, and the consequences of waiting are the same story every time: households paying for avoidable damage and discomfort.
- A small fault becomes a big one A sticking sensor or a choked filter runs the unit harder, and the strain eventually takes out components that a timely service would have protected for years.
- An undersized system costs you daily Living with showers that swing cold teaches your family to race the taps, and fixing the sizing once restores calm mornings permanently.
- Gas faults deserve respect Any unit showing ignition trouble alongside a gas smell needs prompt professional attention, and if that ever describes yours, treat it as urgent rather than inconvenient.
How it works
How the work 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
Fit and commission your unit
We remove any old tank, mount the new unit where it gets shelter from the salt air, upgrade pipework, valves and connections to spec, then test flow, temperature stability and safety devices before walking you through the controls.

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 Greenwich
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 Greenwich 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
We fit instant hot water systems across the peninsula and the surrounding Lane Cove area, reaching Northwood, Wollstonecraft, St Leonards, Longueville and Waverton daily, with the same fixed pricing and the same local crew no matter which side of the ridge you live on.
Good questions, straight answers
What locals ask about instant hot water
How does an instant hot water system work?
A continuous flow system warms water the instant it passes through its heat exchanger, so the hot supply never gives out and no tank sits losing warmth overnight.
Will an instant system cope with two showers running at once?
Yes, provided the unit is correctly sized for your household, so we calculate simultaneous demand before recommending any particular flow rate or model.
Are instant systems suitable for the older homes around here?
Very much so, because a compact wall-mounted unit suits the tight side passages and cramped laundries common in the peninsula's interwar double-brick housing stock.
Does an instant system need its own connection to work?
Every continuous flow unit draws on the household supply for its controls and fan, whether it heats with gas or electricity, so we confirm what your home can carry during the quote.
How long does an instant hot water system last?
With proper servicing, a quality continuous flow unit commonly serves fifteen years or more, comfortably outlasting many storage tanks of equivalent purchase quality.
Can you replace my old tank with an instant system?
Absolutely, we remove the old unit, upgrade the pipework and connections as needed, and leave you with a fixed written price before any work begins.
