Where Continuous Flow Suits Your Home
Continuous flow suits particular homes and habits, and it is the wrong answer for others:
No tank to find room for
The unit hangs on a wall, which matters in a flat where the cylinder currently eats a laundry cupboard.
It never runs out
Water warms as it passes the heat exchanger, so the last shower of the night comes out as hot as the first.
Flow rate sets the limit
One unit can feed several outlets, but only up to its rated flow, so the unit gets matched to the bathrooms and kitchen you actually run at once.
Fuel shapes the install
Gas models want an adequate gas line and a flue route; electric models want a heavy dedicated supply from the switchboard.
How We Fit a Continuous Flow Unit
Every flow unit job follows the same sequence:
- 1

Size the demand
We count the outlets likely to run together, usually bathrooms plus kitchen, and pick a flow rating that covers them without paying for capacity you will never use.
- 2

Check the supply side
Gas models get the line diameter and flue route inspected, while electric models get the existing supply assessed before anyone promises the unit will run properly.
- 3

Mount and connect
The bracket goes on, the water and gas or power connections follow, and a tempering valve keeps the water reaching bathrooms at no more than 50°C.
- 4

Set and prove
We test every outlet, set the controls with you and leave you knowing which dial does what.

What Shapes the Price of an Instant Unit
Here is what moves the figure on a flow unit job:
- The fuel, because a gas model may need line upgrades while an electric one needs the supply checked before it is quoted.
- Where the unit hangs, since a balcony, a laundry cupboard and an external wall each bring different access work.
- Whether an old cylinder comes out with it, which is a full swap covered on our hot water replacement page.
- The valves, because a tempering valve or a new isolation valve can be part of the job.
You get a fixed quote for the whole hot water job first, and we only start once you've approved it. Flat-rate pricing means no hidden fees and no extra fee for weekend or after-hours call-outs, and you can fix now, pay later.

Where Flow Units Fit on These Streets
Built for small households
The average household here held 1.9 people at the last census, and seven dwellings in ten were flats or apartments, so a unit sized to one or two showers at a time matches how most residents actually use hot water. We size the unit to the household.
Cupboard space handed back
Riverside blocks near Bretts Wharf tuck a cylinder into a laundry or balcony cupboard, and swapping the tank for a wall-mounted unit returns that floor space to the flat.
Owners between tenancies
Rental is the norm across these streets, and Hamilton Hot Water Services quotes flow units for owners freshening a flat before new tenants arrive, because a wall unit leaves no cylinder quietly corroding in a cupboard. A brand-new install in a renovation follows our hot water installation process instead.

When We're Not the Right Call
If the electric model you want needs a new circuit to run, that wiring is a job for an electrician, not us. Hamilton Hot Water Services prices only the plumbing around the unit.
Frequently Asked Questions
Call (07) 3523 1736Can a continuous flow unit replace a cylinder in a Hamilton riverside flat?
Often yes, because a wall-mounted unit hands back the whole cupboard, though body corporate sign-off and a check of the building's shared services come first in those blocks beside the river.
Does an instant gas unit need a bigger gas line in an older Hamilton villa?
Frequently it does, because a burner firing on demand draws more gas than a storage cylinder's pilot, so we measure the pipe before promising a wall-hung model for a heritage house.
Will an instant electric model suit a pre-1940 house near Racecourse Road?
Sometimes, but those units pull a heavy load the moment a tap turns, so the switchboard and wiring get assessed first, and any fresh circuit calls for an electrician instead.
Do you install continuous flow units in the rental flats around Bretts Wharf?
We do, and with most dwellings here rented, we work through owners and agents near Bretts Wharf, shutting the riser down and following each block's rules before the old tank comes out.
Is a continuous flow unit cheaper to run than a tank?
Running cost comes down to the fuel and how many showers your household runs, so we compare gas and electric options against your actual use rather than quoting a generic saving.
