A real person answers, day or night
Endless hot water, without a tank taking over the side of the house
Longueville homeowners are discovering what a compact wall-mounted unit does for a house built a century ago, and we can talk you through the options on (02) 9072 0504 before any van rolls.

What we do with instant hot water
Every continuous flow job a peninsula home actually needs, handled under one fixed written quote: sizing, supply, mounting, gas or electric connection, and the servicing that keeps a unit honest for its full life.
Sizing and selection
Choosing the right continuous flow unit starts with the household, because a busy peninsula home running three bathrooms at once needs a different flow rate to a two-person cottage, and we calculate peak winter demand before recommending any new model.
Electric continuous flow
Where gas was never run to a house, modern electric continuous flow units deliver tankless hot water from a standard supply, although some older homes still need wiring upgrades before one connects, which we confirm before quoting rather than after the work starts.
Gas flow upgrades
Homes with an existing gas connection convert to continuous flow cleanly, and our licensed fitters handle the gas sizing, the flue run and the commissioning, matching the unit to burner capacity so showers stay hot even when the laundry competes.
Descaling and servicing
River-side air leaves its mark on outdoor units, so an annual service flushes heat exchanger scale, checks gas pressures and clears strainers, keeping temperature steady and protecting a manufacturer warranty that depends on documented servicing staying current year after year.
If the unit you have is simply at the end of the road, the choice between a repair and a fresh hot water installation is exactly the conversation to have first, and we will give it to you straight.

What goes wrong with continuous flow units
Continuous flow systems fail in predictable ways, and most faults trace back to sizing, supply or servicing rather than anything mysterious inside the box.
Lukewarm winter showers
Groundwater arriving cold through winter forces every unit to work harder, and a model sized for summer demand will struggle, which is why we always size against the coldest inlet temperature rather than the mild months.
Fluctuating temperatures
Temperature swings between the shower and the kitchen tap usually trace to a flow rate dropping below the unit's activation threshold, a fixable sizing or positioning issue rather than a reason to write the system off.
Error codes and lockouts
Gas units lock out for reasons a fitter can read in minutes. A blocked flue, a spent ignition pack or a restricted supply sits behind most codes, and a licensed fitter reads the fault, fixes the cause and restores hot water on the spot.
When the fault is the unit dying rather than misbehaving, a diagnosis through hot water repair tells you honestly whether a component fix will hold or whether replacement is the smarter spend, and a sudden total failure belongs with our no hot water crew instead.
Why acting early matters
- Cold mornings compound An undersized or scaled-up unit degrades exactly when demand peaks, turning the household's worst hour into a daily negotiation over who showers first, and early correction costs a fraction of a rushed emergency swap.
- Renovated finishes pay twice A failed tank wedged beside double-brick walls leaks onto joinery, corridors and storage that a wall-mounted unit would never threaten, so the mounting decision protects far more than the price of the system itself.
- Warranties follow servicing Manufacturers decline heat exchanger claims where the service record has lapsed, and a documented annual flush is the most affordable insurance a continuous flow owner can hold.
How it works
The 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, connect and commission
Your plumber removes the old unit, mounts the continuous flow system in the position you have agreed, connects gas or power supply, fits the tempering arrangement, then runs hot taps throughout the house to confirm stable temperature at every outlet before leaving.

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 Longueville
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 Longueville 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.
That same stocked van covers the whole household, not just the hot water, so a leaking tap, a slow drain or a tempering valve fault gets found while we are already on site.
Where we work
Areas we service
Work reaches daily into Northwood and Riverview, across Lane Cove, and over the river to Woolwich and Greenwich, with every job quoted the same fixed way whether the street is waterfront or ridge top along the peninsula.
Good questions, straight answers
Instant hot water questions Longueville households ask
Will an instant system fit the tight side passage at my house?
Yes, wall-mounted continuous flow units hang on an outer wall and free the floor entirely, which is exactly why they suit the cramped side passages that older peninsula homes keep between their double-brick walls.
Do instant systems really deliver endless hot water?
Within the flow rate the unit is sized for, yes, water heats as it passes through, so back-to-back showers run hot indefinitely, provided the model matches your household's peak winter demand.
Is a gas or electric instant system better for a Federation home?
Gas continuous flow generally suits homes with an existing connection, while electric units work where no gas line was ever laid, and we size both against your inlet temperatures and household demand before recommending either.
How long does a continuous flow unit typically last?
Most quality units serve twelve to fifteen years with proper servicing, and heat exchanger life stretches further where annual flushes keep scale and river-air corrosion from working on the components.
Can an old storage tank be swapped for an instant system in one visit?
Usually yes, because the old tank comes out, the new unit mounts compactly, and supply connections are made the same day, though power or gas line upgrades occasionally add a return visit.
Does an instant hot water system need yearly servicing?
An annual service is recommended, flushing the heat exchanger, checking gas pressures and clearing strainers, and keeping that documented record current protects the manufacturer warranty if a component ever fails.
