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 0517 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
- Original cottages and older brick homes run tight A storage tank simply doesn't fit some service areas on the smaller older blocks, 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
- Long showers 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 service areas in station-precinct units suit a slim system Some of the newer, more compact builds barely give room for a tank at all, and a wall-hung system fits where a bulky storage unit 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 service area freed from a tank becomes storage, or simply room to move past comfortably again.
How it works
Choosing and fitting an instant system, step by step
- 01
Call and tell us
Ring (02) 9072 0517 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 Sutherland
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 Sutherland 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.
Good questions, straight answers
Instant hot water questions Sutherland locals ask
Is it genuinely true an instant unit can't run out of hot water?
Within its rated flow, yes, since it heats water passing through rather than drawing down a fixed store, so duration simply isn't the constraint a tank always eventually runs into.
For my particular house, is gas or electric instant the smarter pick?
Gas tends to suit an existing connection with higher simultaneous demand, electric suits a smaller addition with no gas line nearby, and we size the actual option against your actual house.
If two showers run together, will the pressure drop off?
Only if the unit's genuinely undersized for that load, which is exactly why every fixture likely to run at once gets calculated into the flow rate before we ever recommend a specific model.
People keep mentioning a 'cold water sandwich', what actually is that?
A short cold burst wedged between two hot draws taken close together, caused by the unit briefly losing and regaining ignition, and it's largely a non-issue on a modern unit set up correctly.
Can an instant unit be mounted outside on an external wall?
Yes, and it often makes more sense that way, a wall-hung unit needs proper clearance and venting that an outdoor position usually provides more easily than a tight internal cupboard ever could.
Does warranty cover on a new instant system work the same as everything else?
It's covered from two angles, manufacturer backing applies to the unit itself, and our own labour warranty runs for as long as the installation serves the house, whichever fuel ends up chosen.
