Sydney hot water specialists

The team behind 1,500+ hot water jobs across Sydney

We are not a generalist plumber who happens to do hot water on the side. Roughly four in every ten jobs we attend involve a hot water system; so the diagnosis is faster, the parts are already on the truck, and the install is tidier.

From a 7am tank rupture in Bondi to a planned heat-pump upgrade in Mosman, our licensed Sydney crew has fitted, repaired and rebated the lot. Every job is run by a fully ticketed plumber and gas fitter, every install ends with a Certificate of Compliance, and every quote shows the rebate value on day one; not as a promise to claim later.

  • NSW licensed plumbing & gas
  • WaterMark & WELS registered
  • Rheem, Rinnai & Dux accredited

Before vs After

What changes when a licensed hot water plumber takes the job?

Hot water work is one of the easiest jobs to do badly; and the most expensive when it goes wrong. Here is exactly what shifts when a licensed Sydney plumber handles it instead of a handyman or DIY.

Before

Handyman, DIY or unlicensed install

  • The visible symptom has no confirmed source
  • A repair is chosen before the cause is checked
  • Access or price changes are left unexplained
  • The same symptom returns without further testing
  • There is no clear handover record
Licensed Fixed Today plumber giving a thumbs up

After

Licensed Fixed Today install

  • The fault is checked with a suitable diagnostic method
  • The likely cause and repair options are explained
  • The scope and price are approved before paid work
  • The result is tested before handover
  • Relevant invoice, warranty and compliance records are supplied
What you’ll actually get

The exact thread you’ll see on hot water booking day

No marketing fluff. Every hot water customer gets a thread like this on the day; booked, plumber assigned, ETA, vehicle ID, knock at the door. You always know what’s next.

  1. Booked

    A real plumber assigned, in writing.

    Your 2-hour window, plumber name, vehicle and exact unit being installed; confirmed by SMS within minutes. Not a queue, not a callback.

  2. Routed

    Live ETA, refreshed as they drive.

    Once your plumber leaves the depot the ETA SMS auto-refreshes. No need to call and ask whether they’re still coming.

  3. Warned

    5-minute heads-up at the door.

    We text when the plumber is 5 minutes away, including vehicle and plate so you know who’s knocking before you open the door.

  4. Honoured

    Late-fee waiver, automatic.

    Miss the window without warning and the call-out portion of your invoice is automatically waived. No claim form, no negotiation.

On-Time, Live

We turn up when we say we will; here is the proof

Every hot water job we attended today, with the booked window, the actual arrival time, and whether we hit it. We publish the misses too; and waive the call-out fee when we cause one.

The honest comparison

What other hot water installers won’t tell you.

Side-by-side with what most homeowners actually receive when they pay $3,000 to $5,000 for a hot water replacement; no spin, no fine print. Just what we include as standard, and what tends to quietly get left off elsewhere.

How It Works

What happens when you call us about hot water in Sydney?

Same upfront pricing whether it is a 7am emergency, a planned heat-pump upgrade, or a strata replacement. Here is exactly what to expect from the first call to the warranty card.

Step 01
Step 01

Tell us your unit and what it’s doing

Brand, age, size, and what is happening (no hot water, leaking, lukewarm, error code). We use this to load the right parts; or the right replacement unit; onto the truck before we leave.

Booking Recorded

Visit details confirmed

Contact method Confirmed
Address checked
Access notes Added
Step 02
Step 02

Licensed plumber arrives, diagnoses on-site

A qualified hot water plumber inspects the unit, tests the element or burner, anode rod and pressure relief, and explains exactly what is wrong in plain English; with the unit in front of you.

On-site Assessment

Fault checked in context

Symptoms checked
Likely cause explained
Options As needed
Step 03
Step 03

Repair vs replace, in writing

You get itemised pricing for both options, expected lifespan, and any rebates pre-calculated. You decide. No upsell, no pressure, no “just the cheapest” without context.

Scope and Price

Confirmed before repair

Repair scope Written
Fixed price Confirmed
Approval Required
Step 04
Step 04

Fix or swap, then warranty paperwork

Most repairs are completed on the first visit. Replacements typically take 2 to 3 hours including draining and removing the old unit. Compliance certificate and warranty card emailed before we leave.

Completion Check

Result and records reviewed

Our Guarantee

Two warranties; both in writing, both honoured

Every hot water job is covered by our lifetime workmanship warranty on the install and the full manufacturer warranty on the unit and parts. Both are explained in plain English on your invoice. No fine print, no exclusions you have to dig out of a PDF.

Sizing calculator

What size hot water system does your household need?

Pick your household size; we will show the recommended capacity for every system type, based on Sydney averages and manufacturer sizing tables. The wrong size is the most common reason replacements fail early.

How many people in the home?

Pick "6+" for large families.

Daily need ~200 L/day

Electric storage

250 to 315 L

Sized larger because off-peak elements heat overnight in one go.

Gas storage

135 to 170 L

Reheats much faster than electric, so smaller tanks cope easily.

Gas continuous

24 L/min

Rated by simultaneous outlets. Two showers + a tap usually wants 24 L/min.

Heat pump

250 to 280 L

Slower recovery than gas. Size up if you have back-to-back morning showers.

Solar (boosted)

300 to 340 L

Sized larger to carry through cloudy days without leaning on the booster.

Why licensing matters

Licensed plumber vs. unlicensed worker

Plumbing work in NSW must be carried out by a licensed plumber. It is not just a formality, licensing protects your home, your insurance, and your right to recourse if something goes wrong.

Licensed plumber

What you get

  • Work is insured and meets the National Plumbing Code
  • Compliance Certificate issued for every job
  • Home insurance and warranty stay valid
  • Statutory warranty backed by NSW Fair Trading
  • Clear path to dispute resolution if needed
Unlicensed worker

What you risk

  • Work may breach the NSW Plumbing and Drainage Act
  • No Compliance Certificate: issues at resale
  • Home insurance claims commonly denied
  • No statutory warranty on the work performed
  • Limited recourse: Fair Trading cannot assist
Our NSW Plumbing Licence 236784C Fixed Today Plumbing Pty Ltd

Most home insurance policies will not pay out for damage caused by unlicensed plumbing work. A burst hot water unit from a non-compliant install can void cover on the entire claim, often tens of thousands of dollars.

Angela Kowalski Trustpilot

Fixed Today replaced our old gas hot water system with a new continuous flow unit. The technician explained all the options, helped us choose the right size for our household, and completed the install in half a day. Clean, professional, and the pricing matched the quote exactly.

Hot Water Castle Hill

★★★★★

Our hot water system died on a Friday night. Fixed Today came out Saturday morning, diagnosed the issue, and gave us clear options with pricing before starting any work. New system installed same day. Professional, punctual, and genuinely helpful.

Hot Water Bondi
Michelle Torres Facebook
★★★★★

Had a gas fitting job that two other plumbers quoted differently on. Fixed Today explained exactly what was needed, showed me the compliance requirements, and completed the work with full documentation. Very impressed with the professionalism.

Gas Fitting Chatswood
Samantha Wright Facebook
★★★★★

Needed a gas cooktop installed during our kitchen reno. Fixed Today handled all the gas compliance paperwork, coordinated with our builder, and installed everything to code. The follow-up safety check was a nice touch. Really thorough service.

Gas Fitting Rhodes
Ryan Patel Trustpilot
★★★★★

Called about a running toilet that was wasting water. They sent someone the same afternoon and it was sorted within an hour. Flat rate pricing, no call-out fee, and the plumber was friendly and knowledgeable. Exactly the kind of service you want.

Used Fixed Today for a stormwater drainage issue at our property. They did a camera inspection, showed me the footage, and explained the options clearly. The repair work was completed on schedule and they followed up a week later to check everything was flowing properly.

Homeowner’s Handbook

How to choose a hot water system you won’t regret

A short editorial guide written by our senior hot water plumbers. No fluff, no brand bias; just the checks an experienced homeowner makes before signing off on a $4,000 install.

Homeowner checks

The six checks that matter most

  • Size before brand; always
  • Get the running cost, not just the install price
  • Confirm the rebate is locked in, not hoped for
  • Demand a Certificate of Compliance, not a receipt
  • Check the tempering valve is in the quote
  • Insist on itemised, not lump-sum
  • Set up the new system so it actually saves you money
Quote checklist

Walk-away signs on a hot water quote

  • No model number on the quoted unit
  • Rebate “applied later” with no figure on the quote
  • No mention of a tempering valve on a replacement
  • Compliance certificate as an optional extra
  • Pressure to decide on the day to lock in a discount
  • Old unit “removed” with a kerbside disposal photo
Trust check

Verify a hot water plumber’s licence yourself. Service NSW lets anyone verify a plumber’s contractor licence in under a minute; and a hot water install legally requires one. Bookmark the link: it is the single most useful tool a homeowner has.
