Endless hot water without the tank, for busy households on the ridge
Storage cylinders run out. Continuous flow systems do not, because they heat water the moment a tap opens and keep heating it for as long as the tap stays open. For families running back-to-back morning showers, that changes the household rhythm entirely, and the unit itself takes up a fraction of the wall.
Why instant systems suit the local housing stock
- Mid-century homes are short on laundry space The brick-veneer houses built out through the 1960s and 1970s often carry a storage cylinder squeezed into a tight external wall or a cupboard that was never designed for it. A compact continuous flow unit frees that space and mounts neatly on a single bracket.
- Newer townhouses near the railway station have different loads Those developments usually run smaller, multi-level floor plans where a wall-mounted instant unit, vented directly outside, suits the layout far better than a floor-standing tank.
- Long-held family homes favour simple, durable kit Owner-occupied households that stay for decades tend to value equipment that needs little attention, and a quality continuous flow unit with an annual check fits that expectation well.
What we install and service
Replacing a tired cylinder, building new or chasing a fault all sit under this work, each job quoted upfront and completed to code. If you are weighing instant against the alternatives, our pages on gas hot water systems and electric hot water systems lay out the honest trade-offs.
Continuous flow gas units
Continuous flow gas units heat water only when a tap actually calls for it, which suits busy family households on the leafy ridge streets wanting endless showers without a bulky storage tank taking up outdoor laundry or garage wall space.
Electric point-of-use heaters
Compact electric point-of-use heaters mount under a sink or beside a shower where a storage cylinder never fit, an answer for townhouse layouts and older cottages needing hot water in a far corner without long pipe runs.
Storage-to-instant conversions
Replacing an ageing storage cylinder with continuous flow frees the external wall, ends running-out showers and suits the crisp ridge winters, though the home's gas supply sizing and correct fluing must first be checked before any unit is specified.
Whole-home or point-of-use
Choosing between a single whole-of-home unit and several point-of-use units depends on bathroom and kitchen positions, household size and existing pipework, and we map usage patterns before honestly recommending either path for your household's daily routine, not a catalogue default.
The ridge changes the maths on instant systems
- Colder incoming water in winter At roughly 183 metres above sea level, nights here run noticeably cooler than the coastal plain, and winter inlet water arrives colder as a result, so the unit must lift the temperature further than brochures assume.
- Flow rate sizing matters more here Because that colder inlet forces the heater to work harder, an undersized unit drops its delivery rate exactly when everyone wants a long shower, which is why we measure real household demand before specifying anything.
- Old decisions hide behind new units Plenty of long-held family homes still run plumbing choices made decades ago, so when we size a replacement we measure the actual load of the house rather than copying whatever tank hung on the wall before.
Faults we get called to on instant systems
Most instant system complaints turn out to be serviceable faults rather than dead units, and diagnosing them properly with instruments saves owners from replacing hardware that still has years in it. Where a unit genuinely has reached the end, we will say so plainly and talk through a hot water replacement instead.
Temperature swings mid-shower
Temperature spikes when another tap opens are the classic instant system complaint in these units, usually a serviceable flow sensor or minimum-flow setting issue rather than a faulty heater, and most are resolved in a single visit.
Fires, then nothing
A unit that fires then shuts down, or delivers only cold water, often points to ignition, gas supply or scale restrictions on older installations, faults we diagnose with proper instruments on site before any part is replaced.
Undersized for winter
Undersized units struggle on cold ridge mornings because incoming water arrives several degrees lower, so the flow rate drops as the heater works harder, a sizing problem we can measure and correct with the right unit for the household.
Why acting early matters
- Small faults stay small while they are affordable A flow sensor or ignition component replaced promptly is a modest job; left alone, the same fault can stress other components and turn a repair into a replacement decision made under pressure.
- A failed unit never fails at a convenient hour Sudden loss of hot water in a house full of school morning routines becomes an urgent call, and if that happens to you, our no hot water page explains what to do first while we get a plumber to you.
- Correct sizing pays you back every winter A unit matched to your household's real peak demand delivers steady temperature on the coldest mornings and avoids the running-cost penalty of an oversized heater cycling away unused.

Good questions, straight answers
Questions about instant hot water from local homeowners
Are continuous flow systems more economical to run than storage tanks?
Continuous flow units heat water only while a tap is open, avoiding the standby losses of a storage tank, which many households see reflected in lower energy bills across a year.
Can you convert an electric storage system to gas continuous flow?
Yes, and it is a common upgrade here, but we first confirm the gas meter and supply lines can carry the new load, then run correct fluing and a compliant connection before commissioning the unit.
Do instant systems cope with cold ridge-top winters?
They do when correctly sized, because incoming water on the ridge arrives colder in winter and the unit must raise its temperature further, so we match the flow rate to your household rather than guessing.
How long does an instant hot water installation take?
A straightforward swap usually finishes within a day, while conversions from storage tanks that need gas line upgrades or new fluing can run longer, and we tell you the honest timeframe before starting.
Is the installation work licensed?
Every job is completed by a licensed plumber under licence #275278C, with gas connections handled by licensed gas fitters and all compliance certificates supplied with your invoice without you needing to ask.
What warranty covers a new instant system?
Our Lifetime Labour Warranty covers the workmanship whenever a fault appears, while the manufacturer's parts warranty runs alongside it, and we register everything properly so the paperwork protects you.
