Plenty of Grange houses already run one. Others make the switch when an old cylinder finally gives out. This page explains how the units work, whether one suits your place and what the fitting involves.

Where Continuous Flow Suits the House
A continuous flow heater is a wall-hung box with a heat exchanger inside. Water passes through it and warms on the way, so storage is never the question. It earns its place when:
Nobody wants to ration showers
The heater runs as long as water flows, so the fourth shower on a school morning is as hot as the first.
Floor space comes back
With no cylinder to house, a cupboard, a laundry corner or the slab beside the house frees up.
The household is small or spread out
One or two people use little, and a far bathroom still gets hot water without a second tank.
Fuel decides the model
A gas unit needs a supply line sized for its burner, while instant electric pulls heavy current and wants its own circuit, which is a job for an electrician.
Flow rate is the honest limit. The unit heats everything passing through it, but only so much at once, so the rating on the box decides how many outlets run together.
How a Continuous Flow Install Runs
- 1

Check the supply side
Gas lines get sized against the burner's demand, and an electric connection gets assessed before any hardware is ordered.
- 2

Hang the unit
We mount the bracket, set clearances from eaves and windows, and run the flue where a gas model needs one.
- 3

Connect water and fuel
Water in and out, the gas or power connection, plus new isolation and tempering valves where the old setup lacks them.
- 4

Test and set
We set the temperature, run every hot tap and confirm the tempering valve keeps bathroom outlets at 50°C.

Price Drivers for Continuous Flow
Gas or electric hardware
The two units differ in cost and in the connection work behind the wall.
The supply itself
An undersized gas line, or a switchboard that needs attention first, adds work before the heater can run.
Where it hangs
A clear outside wall is quick; a recessed spot, or a swap that also removes an old cylinder, takes longer.
Valves and fittings
A tempering valve or new isolation points are small line items we list plainly.
Every hot water job is quoted as a fixed price before any work starts, and nothing goes ahead until you say yes. We keep to flat-rate pricing with no hidden fees and no surcharge for nights, weekends or public holidays. Fix now, pay later is available as well.

Continuous Flow in These Streets
Old piping shapes the shower you get
Many pre-war homes here still carry their first galvanised supply lines, and decades of corrosion narrow them from within. A continuous flow heater only warms what actually arrives, so a strangled pipe shows up as a disappointing shower long before the unit itself is at fault. We check the delivery side before blaming the heater.
Wall-hung suits the housing stock
The interwar and pre-1940 homes near Wilston State School sit on compact lots, and a heater that hangs on a wall leaves the ground clear for gardens, bikes and the general clutter of a family house. Local Grange Hot Water fits these units right across the suburb.
Big households need the right rating
Around 47.8 per cent of homes in the area have four or more bedrooms, going by census data. When two showers and the kitchen tap run together, an undersized unit struggles, so we size the flow rating to the way your family actually uses water.
If you would rather keep a tank, hot water installation covers new systems of every type, and hot water replacement covers the swap when an existing unit is finished.
When we're not the right call. The heavy dedicated circuit an electric continuous flow unit wants is electrical work, so a licensed electrician handles that side before we hang anything.

Frequently Asked Questions
Call (07) 3523 7158Will a continuous flow unit run out during a busy family morning in Grange?
No, a continuous flow heater warms water only as it flows, so back-to-back showers in one of the big family houses around Grange keep going for as long as anyone stays in.
Can a wall-hung unit suit the older houses near Wilston State School?
Yes, a wall-hung unit takes up no floor space, which suits the compact pre-war blocks near Wilston State School, where a cylinder in the laundry can crowd a whole room.
Is Energex part of an instant electric installation in Grange?
Only if the switchboard itself needs attention; the unit's heavy current means a licensed electrician wires the dedicated circuit, and Energex comes into it when the supply side needs their sign-off.
Will a gas continuous flow heater run on bottled LPG at a Grange house?
Yes, if your Grange property has no mains gas supply, a gas continuous flow heater can operate on bottled LPG, and we configure the unit to match the fuel available at your place.
Does Council's character overlay limit where an instant unit can hang?
Usually the unit hangs on an outside wall, so the original walls of these character houses stay untouched, and we plan the spot around the overlay Council applies to many older homes here.
