The Case for a Wall-Mounted Unit
A continuous flow unit swaps a big cylinder for a compact box that heats water the moment it moves through the heat exchanger:
No recovery wait
Because nothing is stored, the last shower in a crowded household arrives just as hot as the first.
A smaller footprint
A wall unit frees the yard spot a tank once took, which matters where sheds and the old backyard stables already fill the ground.
Gas or electric
Gas models need a supply line with enough grunt to feed the burner, while electric models draw hard enough that the circuit itself is an electrician's call.
How We Put a Unit on the Wall
- 1

Size it first
We count the outlets likely to run together and choose a flow rating that covers the busiest part of the morning.
- 2

Sort the supply
A gas unit needs pipework delivering enough volume to the burner, and an electric unit's heavy load gets checked on the household wiring before booking proceeds.
- 3

Mount and connect
The bracket goes up, isolation valves go in, and every gas joint is made and checked to the standards gas fitting requires.
- 4

Commission it
Delivery temperature is set, the tempering valve holds bathroom water at 50°C or below, and we run hot water at every tap with you watching.

Pricing a Continuous Flow Install
Four things move the figure on an instant unit:
- The energy source behind it, since gas supply work and electric circuit questions are different jobs.
- The flow rating the household needs, because homes with several bathrooms step up a model size.
- The condition of the water supply pipes, where aged galvanised runs sometimes want renewing in the same visit.
- Where the unit hangs, since flue clearance and wall access change the hours on site.
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.

Instant Units on These Older Blocks
Big families run overlapping showers
Census counts put every second dwelling in the postcode at four bedrooms or more, and those family homes have long lived on one large storage cylinder. A flow-through unit sized to the morning bunch ends the wait between showers entirely.
Small households get small units
The average household here counted 2.7 people at the last census, so plenty of homes along streets like Derby Street need a modest flow rating rather than the biggest cabinet on the market. Hendra Hot Water Services sizes to the house in front of us, never to a catalogue default.
Old switchboards are the catch
Houses from the racing decades predate modern electrical loads, and instant electric wants a serious dedicated circuit, so the switchboard may need an electrician's word before a power unit makes the shortlist.
If the fault sits in the unit you already own, our hot water repairs page is the starting point, and trading a dead cylinder for a flow-through model belongs on hot water replacement. A brand-new build or renovation where no unit has sat before is covered under hot water installation.

When We're Not the Right Call
If your home needs a new dedicated circuit or an upgraded switchboard to run an electric instant unit, that wiring belongs to a licensed electrician, not to us.
Frequently Asked Questions
Call (07) 3523 1856How many outlets can run at once off a flow-through unit?
The unit's flow rating decides that rather than a tank, so during the quote we count which showers and taps in your household will overlap and size to the busiest stretch.
Will Hendra's older galvanised pipe hold back a continuous flow unit?
It can, since corroded runs behind the weatherboard walls of the racing decades throttle pressure at the taps, so we test what the household supply actually delivers before quoting.
Does Energex's off-peak tariff matter for instant hot water?
No, because a continuous flow unit heats at the moment you draw, not overnight, so the off-peak supply stays behind with storage tanks, and electric instant instead needs a dedicated circuit.
Where a street has no gas main, does instant still work in Hendra?
Yes, an LPG bottle feeds a gas unit where no main runs, or an electric model covers it, though electric instant draws hard, so the cabling work sits with a qualified sparkie.
Does a frost-free local winter change how an instant unit performs?
Not really, our winters stay mild and frost-free, and a flow-through unit heats the same on a July morning as midsummer, with the delivery temperature set during commissioning either way.
