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

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
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
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.
- 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.
- 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.
- 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.
- 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.
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.
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.

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.
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
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
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
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
Emergency call; we triage in 60 seconds
Tank rupture, no hot water with a baby in the house, gas smell. We know what is genuinely urgent and dispatch the closest plumber with a replacement unit on board.
Urgent Call Logged
Risk details recorded
Make it safe while we’re en route
We talk you through shutting the cold inlet, isolating power or gas safely, and protecting flooring; so by the time we arrive, damage is already contained.
Immediate Safety
Next safe step explained
Same-day swap, no overnight cold showers
Common 50L to 315L electric and gas units carried on the truck. Heat-pump units typically delivered next-day for emergency replacements with a temporary unit fitted in the meantime where possible.

Work Recorded
Outcome explained
Site review and access requirements
Strata, hospitality, gym, aged-care or commercial laundry? We coordinate with building management, lift bookings, and after-hours access ahead of the install.
Access Details
Entry and parking recorded
Compliance and SWMS
Plumbing licence, gas licence, $10M public liability, SWMS and JSA documents prepared and supplied before we step on site; no chasing.
Responsibility Check
Shared services considered
Scoped quote with three options
Repair, like-for-like replacement, and an efficiency upgrade option (heat pump or solar) presented side by side with payback periods and rebates costed in.
Fault Located
Evidence guides the repair
Scheduled install around your operations
After-hours, staged, or weekend installs available. We handle disposal of the old unit and provide WHS sign-off and a compliance certificate for your records.
Next Step Agreed
Access, scope and price clear
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.
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.
Electric storage
Sized larger because off-peak elements heat overnight in one go.
Gas storage
Reheats much faster than electric, so smaller tanks cope easily.
Gas continuous
Rated by simultaneous outlets. Two showers + a tap usually wants 24 L/min.
Heat pump
Slower recovery than gas. Size up if you have back-to-back morning showers.
Solar (boosted)
Sized larger to carry through cloudy days without leaning on the booster.
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.
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
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

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.
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
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
