Choosing the System and the Spot
A new install gives you a free hand, which makes the decisions worth taking slowly. Three questions come first:
How much hot water does the household actually use?
A couple in a unit needs far less capacity than a family of five in a detached house, and oversizing wastes money every heating cycle.
Where can the unit physically go?
A tank on a slab next to a detached house is a simple job. Cupboards, balcony corners and plant rooms in apartment blocks need careful measuring before anything is ordered.
What does the property already have?
A gas connection points toward gas storage or continuous flow; an Energex supply suits electric storage or a heat pump; a roof with good aspect opens up solar.
Get those three answered and the right system usually picks itself. We talk through every option on site before you commit.
The Install, Step by Step
Every job follows the same sequence, whether it is a new tank beside a villa or a flow unit tucked into a renovated laundry:
- 1

Site check and quote
We measure the space, confirm the water, power or gas supply, and price the complete job before hardware is ordered.
- 2

Prep and isolation
Water off at the mains, the old supply lines capped where needed, and the mounting spot prepared.
- 3

Mount and connect
The tank or flow unit goes in, then the cold inlet, hot outlet, isolation valve and relief valve are fitted.
- 4

Fill, heat and test
We fill the system, heat the tank past 60°C, set the tempering valve so no bathroom outlet exceeds 50°C, and check every joint under pressure.
- 5

Handover
You get a walk-through of the valves, the booster or thermostat settings, and what a fault looks like if one ever appears.

What Drives the Install Figure
The figure on a new install comes down to a short list:
- The system itself, because a storage tank, a heat pump, solar collectors and a continuous flow unit carry very different hardware.
- The install location, since a tank on a concrete slab is a shorter job than one carried into a tight cupboard up a tower.
- The supply it connects to, because a gas unit brings gasfitting on the supply line while an electric swap usually reuses what is already there.
- Extras like new valves, a tempering valve or pipe rerouting for a relocation.
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 New Systems Go Around These Streets
The riverfront flats
Along the Northshore reach, the old wharf land was built up on fill over river mud, and groundwater runs close beneath it year round, so a trench for new pipework needs pumping out before a line goes in.
The hill villas
Around Annie Street and the other hill addresses, heritage houses can still carry galvanised iron runs behind the walls, and Hamilton Hot Water Services inspects those before connecting a new tank, because fresh hardware fed by tired pipe never performs as it should.
We write both realities into the quote on the day, not after it.

Where an Installation Is Not the Right Call
If your new system needs a fresh power circuit or a switchboard upgrade, that wiring is a job for a licensed electrician, and Hamilton Hot Water Services would rather say that up front than muddle the install.

Frequently Asked Questions
Call (07) 3523 1736Do renovations in Hamilton need council approval before a hot water installation?
Renovations and new builds can trigger council plumbing approvals, while a straightforward swap usually does not, and Hamilton Hot Water Services flags anything your project needs before any work begins.
Can a heat pump go on a balcony in the Northshore riverfront flats?
Sometimes, if the flat has an outdoor spot with good airflow well away from bedroom windows, though the body corporate across the Northshore redevelopment decides what may sit outside, so check with them first.
Does an Energex off-peak supply change how a new electric tank is installed?
Usually no, because a storage tank keeps the existing Energex supply as it stands, but an instant electric model draws heavily and wiring a fresh circuit for one is your electrician's job.
Do you install gas systems near Bretts Wharf?
Yes, gas systems near Bretts Wharf are covered by our gasfitting licence, so the same crew connects an electric or a gas unit from the supply through to final testing.
Does install work differ between the hill streets and the riverfront?
Yes, the hill villas often still carry galvanised pipe under their walls, while the riverside flats sit on soggy fill, so access and trenching get checked before we quote either job.
