Who a Flow Unit Suits
A flow unit suits plenty of homes here, but it is not the automatic answer for everyone. These points decide it:
The supply never runs out
Water heats as it passes through the heat exchanger, so the last shower comes out as hot as the first.
Size follows usage
The flow rate decides how many showers and taps run together, so we match the unit to the way your household actually uses water.
Gas or electric
A gas model needs an adequate gas supply and pipe size behind it, while an electric model needs wiring capacity well beyond an ordinary power point.
No tank to find room for
Most units hang on the wall, which matters wherever cupboard space is tight.
How We Fit a Flow Unit
Every install runs the same four steps, whether it is a straightforward swap or a first-time fit:
- 1

Check the services
We look at the gas line size or the power available, the flue path and where the unit can realistically mount.
- 2

Quote the whole job
You get one figure covering the unit, the mounting, the connections and any old tank removal, and it does not move once you approve it.
- 3

Fit and connect
The unit goes on the wall, then we run the gas, water and flue connections and pressure test every joint before covering up.
- 4

Set and hand over
We set the delivery temperature, confirm the tempering valve keeps water at the taps no hotter than 50°C, and show you how the controls work.

What Sets the Price
Four things move the figure on a flow unit install:
- The fuel source, because a gas connection and flue come together while an electric model leans on the wiring side.
- Where the unit mounts, since an outdoor wall is simpler than a tight indoor cupboard with clearance rules.
- The gas line, because some older lines need upsizing before a flow unit will run at full rate.
- Whether an old tank has to come out, as removal and disposal add time to the day.
We price your hot water job up front as one fixed figure, and you decide whether we go ahead. There are no hidden fees with our flat-rate pricing, no surcharge for nights, weekends or public holidays, and the option to fix now, pay later.

Continuous Flow Units Around Chermside
Younger households, compact homes
The census put the median age here at 35 and most residents rent, so hot water often needs to be compact, cheap to run and quick to bring back when it fails.
Indoor tanks in the older blocks
Apartment buildings from earlier decades near the shops still hold small cylinders inside, and swapping one for a wall-hung flow unit is a replacement job that takes the leak risk out of the cupboard and frees that space for storage.
No frost, but hail
Frost never settles in an average year around here, so outdoor mounting is straightforward, though the November to March storm season throws hail about, which we allow for when picking the spot.
A renovation adding a second bathroom or a build coming out of the ground is an installation conversation instead, and the same sizing logic applies.
When we're not the right call: an electric flow unit draws more current than an ordinary household circuit carries, so the dedicated feed and any switchboard work are electrical jobs, handled by an electrician before we connect anything.
Frequently Asked Questions
Call (07) 3523 7118Can a continuous flow unit fit inside a Chermside apartment?
Usually yes, because a wall-hung gas unit frees the cupboard space an indoor tank eats, though the gas line size and flue path decide what fits inside an older block.
Does an instant gas unit cope with two showers at once?
It comes down to the flow rate and the gas supply size, so we size the unit against what your showers and taps draw at the one time, not the figures printed on a brochure.
Does an instant electric unit need special wiring on an Energex supply?
It pulls a bigger current than a household circuit is built for, so a licensed electrician runs the dedicated feed and handles any switchboard change before we connect the unit.
Are flow units a good fit for Chermside's rental units?
Often, because a wall-hung unit with no tank to rust suits small households, and the last census counted the average dwelling here at fewer than two people, so capacity is rarely the issue.
Can a continuous flow unit replace a leaking indoor tank?
Yes, and swapping a tired indoor cylinder for a wall-hung unit frees the cupboard, though we check the flue path and gas line before quoting the changeover in an older block.
