A second bathroom rarely comes with room for a second tank
Adding an ensuite or a downstairs powder room during a renovation usually means finding space that was never planned for hot water at all. Call (02) 9072 0511 and a licensed plumber will weigh up honestly whether an instant unit beats extending the existing system.
Weighing up a storage tank instead? Gas and electric tanks haven't gone anywhere, and the hot water overview lines every option up together for a proper look.
Two building patterns on this estate push people toward instant
- A new bathroom often sits well away from the original tank Second-storey additions along Shannon Avenue and Sligo Close have added bathrooms a good distance from wherever the household's existing hot water system sits, and running a long pipe back to a shared tank rarely performs as well as a unit fitted closer to the new fixture.
- Original service yards weren't built with spare room The single-level 1960s layout these houses started from often left a tight laundry or side path, and a compact wall-hung unit fits where a full storage tank simply can't.
Two fuels, one goal: never waiting for the tank to catch up
Running on the existing gas supply
Where a house already has gas connected, a continuous-flow unit taps straight into it, firing up only while a tap's genuinely open and delivering strong, steady recovery even when the household's asking a lot of it at once.
Running on power instead
For a spot with no gas nearby, a compact electric unit does the same job at the point of use, a sensible pick for a smaller addition or wherever trenching in a new gas line would cost more than it's worth.
Matching the unit to actual demand
Every tap, shower and appliance that could plausibly run at the same time gets counted before a model's chosen, because two people showering while the kitchen tap's running pulls considerably more litres a minute than either fixture alone.
Getting the mounting spot right
Where the unit ends up matters almost as much as which one gets chosen, since proper clearance, a clean flue path and room for a technician to service it later all shape how well it holds up over the years.
Cool nights on the plateau change what a unit needs to deliver
- Colder mains water asks more of the same rated unit A model that copes fine on a mild evening closer to the harbour can fall short here once genuinely cold plateau nights drop the starting temperature further.
- Sizing gets built around winter, not an average day A unit rated for a comfortable spring afternoon isn't automatically the right one for the coldest week of a plateau July, so winter performance gets checked, not assumed.
What actually goes wrong with an instant unit
Pressure sagging when a second fixture joins in
If the shower noticeably weakens the moment someone opens a tap elsewhere in the house, that's the unit telling you it wasn't rated for this household's real peak, and sizing it correctly solves it properly rather than papering over it.
A brief chill between two back-to-back showers
A short cold snap right as the unit re-ignites between one hot draw and the next, sometimes called a cold water sandwich, is largely a non-issue on a well-tuned modern unit set up with the right flow and temperature settings.
Comparing every fuel type side by side? The hot water hub sets gas, electric and instant out together.
What a properly matched unit gets you that a mismatched one won't
A shower that stays strong isn't luck, it's sizing
Weak pressure two fixtures into a busy morning is a rating problem, not a fault, and the fix is choosing correctly the first time rather than living with a workaround.
Nothing's ever heated and left waiting
Without a tank holding a standing reserve, there's no water kept hot overnight for a shower nobody's taking, which is the whole point of going tankless in the first place.
A freed-up cupboard earns its keep
Space that used to hold a tank turns into linen storage, a garden nook or simply a wider path through a tight side yard once the wall-hung unit's in.
How it works
Choosing and fitting an instant system, step by step
- 01

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 test under load
Once it's mounted where agreed, the fuel supply, water line and any flue get hooked up, and before anyone signs off, the busiest combination of taps in the house gets tested together to prove the flow holds up.

Good questions, straight answers
Instant hot water questions Killarney Heights locals ask
We added an ensuite upstairs years after the house was built. Would a dedicated instant unit suit it better than extending the existing tank's run?
Often, yes, water travelling the full distance back to one shared tank cools down along the way and takes noticeably longer to arrive, so a compact unit fitted near the new bathroom tends to work out better.
Does the cooler weather up here change how an instant system should be sized?
It does, incoming water starts colder on genuinely cold plateau nights, so the unit needs enough capacity to still hit temperature at a decent flow rate, not just on a mild evening.
Between gas and electric, which instant option actually suits our house better?
Gas tends to win where a connection's already run and demand overlaps heavily, while power suits a spot the gas line never reached, and the actual call gets made against your household, not a blanket rule.
Will running two showers at once cause the flow to drop?
Only if the model chosen genuinely can't cope with that load, which is exactly why every fixture likely to be drawing hot water together gets tallied up before a unit's ever recommended.
Can a compact instant unit go on an external wall near the original service yard?
Yes, and it's frequently the easiest option, because an outdoor wall typically offers the breathing room and venting a mounted unit needs far more readily than a cramped indoor cupboard does.
Is a newly installed instant system covered by warranty?
It's a two-part guarantee, the hardware itself is backed by the manufacturer, and separately, our own crew's labour carries the Lifetime Labour Warranty no matter which fuel ends up going in.
