A real person answers, day or night
Never run out again, no matter how long everyone's shower actually runs
An instant system heats water only as it's drawn, so there's no tank to empty and no cold surprise halfway through. Call (02) 9072 0520 and we'll size the right unit to your household.
Prefer a tank instead? Gas and electric storage both remain solid choices, and the full hot water range compares every option in one place.
Space, not fuel type, is often the real reason instant wins
- Weatherboard and older cottages run tight A storage tank simply doesn't fit some service yards on the smaller blocks near the village, while a wall-hung instant unit needs only a fraction of the footprint.
- Renovations reclaim the old tank's spot Bathroom and laundry upgrades often want that cupboard space back for storage, and swapping to instant during the renovation frees it up for good.
Instant hot water, done properly
Instant hot water isn't one product but a choice between fuel, flow rate and position, and getting all three right is what separates a great system from a disappointing one:
Gas continuous-flow units
Gas continuous-flow units heat water on demand with genuinely strong recovery, suited to a household that wants endless hot water without the added running cost of keeping a full tank hot around the clock for no real reason at all.
Electric instant units
Electric instant units skip gas altogether entirely, heating water right at the exact point of use, a genuinely tidy option for a small bathroom addition or a spot where running a gas line simply isn't worth the trouble at all.
Sizing for flow rate
Sizing an instant system properly means honestly matching flow rate to every fixture running together at once, because two full showers and a kitchen tap running simultaneously always demand more litres per minute than one shower alone will ever need.
Wall-hung positioning
Wall-hung positioning and proper venting decide how well an instant unit ultimately performs day to day, with clearances, flue runs and clear access for servicing all worked out properly before the unit goes anywhere near the actual finished wall itself.
Two more local patterns shape who benefits from going instant
- Teenagers make duration the enemy, not volume A household running back-to-back long showers before school never empties an instant system the way it drains a tank dry, because there's simply nothing left to run out.
- Tight side passages near the station suit a slim unit Some of the older interwar blocks barely give a metre of clearance, and a wall-hung system fits where a bulky tank never realistically could.
Common instant hot water problems, explained
Flow rate dropping mid-use
Flow rate dropping suddenly when a second tap opens elsewhere usually means the unit is undersized for the household rather than genuinely faulty, and the honest fix is a properly rated system, not an awkward workaround.
The cold water sandwich
A cold burst between hot and hot, the so-called cold water sandwich, happens when a unit briefly loses ignition between two uses close together, and a modern unit with the right settings largely eliminates it entirely.
Why the right instant choice matters from day one
Choosing the right instant system properly, sized to the fixtures it actually needs to serve, avoids the two complaints that send people back to a plumber within the first year:
- An undersized unit gets blamed for a sizing mistake A weak shower isn't a fault to fix repeatedly, it's a flow-rate problem, and the honest solution is the right-sized system from the start.
- No tank means no standing loss, ever An instant system heats nothing until a tap opens, so there's no overnight energy wasted holding water hot for nobody to use.
- Space saved is space you can actually use A cupboard or side passage freed from a tank becomes storage, a garden bed or simply room to walk past comfortably again.
How it works
Choosing and fitting an instant system, step by step
- 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
Mount and connect
We mount the unit properly in the agreed position, connect gas or power, water and the flue where one's genuinely needed, then run every tap and shower together to prove the flow rate holds under real demand while we're still on site.

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 Oatley
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 Oatley 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
Instant systems, gas or electric, get mounted across Oatley plus neighbouring Mortdale, Hurstville Grove, Connells Point, Peakhurst Heights and Penshurst, sized to the household and positioned properly, tight spaces included.
Good questions, straight answers
Instant hot water questions Oatley locals ask
Can an instant system really never run out of hot water?
For its rated flow, yes, because it heats water as it passes through rather than storing a finite amount, so duration stops being the limit that a tank always eventually hits.
Is gas or electric instant better for my house?
Gas suits an existing connection and higher simultaneous demand, while electric suits a small addition with no gas line nearby, and we size the real option to your actual house.
Will two showers running together lose pressure?
Only if the model itself is genuinely too small for that demand, which is exactly why we calculate flow rate for every fixture that might realistically run at once before recommending one.
What is the cold water sandwich everyone mentions?
A brief cold burst between two hot draws close together, caused by the unit briefly re-igniting, and it's largely solved on modern units with the right flow and temperature settings.
Can an instant unit go on an external wall?
Yes, and it often should, since a wall-hung unit needs proper clearance and venting that an external position usually provides far more easily than a cramped internal cupboard space allows.
Is a new instant system covered by warranty?
It's covered twice over. Manufacturer backing applies to the unit, and our own labour is promised for as long as the installation serves the house, whichever fuel you settled on in the end.
