Our story
Built because hot water quoting was a dog's breakfast
Same unit, same suburb, three quotes hundreds of dollars apart — and not one of them explaining which rebate was doing what. We figured households deserved better than that.
The problem
Hot water eats a quarter of the power bill
For most Victorian households, hot water is the second-biggest energy cost after heating. Old electric storage tanks and ageing gas units quietly burn money every single day — and nobody thinks about it until the thing fails on a Sunday night.
Where we came from
Born out of Sunline Energy, established 2015
Sunline Energy has been in the renewables game across Melbourne since 2015 — rooftop solar, battery storage, EV charging and electrical work for homes and businesses. Sunline Heat Pumps is the dedicated heat pump hot water division of that business, so you get a decade of energy-industry experience behind a specialist team.
Why we started
The quoting process was a mess
Three quotes, three different 'rebate included' numbers, and nobody willing to explain which certificates were actually being claimed. We built Sunline Heat Pumps to price hot water the way it should be priced: RRP, each rebate line itemised, final installed number.
How we work now
Specialists, not a general trades outfit
We only do heat pump hot water. That focus means our team knows the quirks of every model we sell — which units struggle on a frosty Melbourne morning, which need extra clearance, which controllers actually let you run on cheap daytime solar.
Where we're headed
Getting Melbourne off gas hot water
Every gas storage unit we replace cuts roughly a tonne of CO₂ a year. The goal is simple: make switching so easy and so obviously worth it that there's no reason to replace like-for-like.
What we stand for
Four rules we don't bend
Brand-agnostic, always
We stock a spread of brands because no single unit suits every home. If the cheaper model is the right one for your place, that's the one we'll quote.
Rebates off the invoice, not 'later'
Solar Victoria, STCs and VEECs come off before you pay. No fronting the money, no waiting on a cheque, no 'up to' pricing that moves at the door.
Do it properly or don't do it
Licensed plumbers and sparkies, compliance certificates issued, old unit decommissioned and recycled. Every job, every time.
No-nonsense advice
If a heat pump isn't right for your home, we'll tell you. We'd rather lose the sale than land you with a system that doesn't suit.
How it goes
Quote to hot water, start to finish
Have a yarn
Tell us what you've got now, how many people are in the house, and where the unit sits. Five minutes on the phone or through the quote form.
Eligibility check
We confirm which of the three rebates you qualify for before we quote a price — so the number you see is the number you pay.
Fixed quote, rebates itemised
One page. RRP, Solar Victoria, STCs, VEECs, install inclusions, final price. No fine print surprises.
Install day
Usually half a day for a straight swap. Old unit removed, new system commissioned, compliance paperwork issued on the spot.
Aftercare
Warranty registered for you, claims lodged, and a real person on the phone if something plays up down the track.
Accreditation & compliance
The paperwork that actually matters
Rebates only get paid when the retailer, the product and the installer are all approved. Here's what sits behind every Sunline job.
NETCC Approved Seller
New Energy Tech Consumer Code — the national benchmark for fair sales and clear contracts.
Solar Victoria authorised retailer
Required to lodge the $1,000 standard state hot water rebate (or $1,400 for approved locally-made models) on your behalf.
Accredited VEU provider network
So your VEEC discount is applied properly at the point of sale.
Licensed plumbers & electricians
Every install signed off with a compliance certificate under Australian Standards.
Team of accredited experts
Heat pump specialists only — not a general trades outfit doing hot water on the side.
Responsible decommissioning
Old tanks removed, refrigerant handled correctly, steel recycled.

Why it's worth doing
A heat pump uses roughly a quarter of the energy of an electric resistance tank and cuts about a tonne of CO₂ a year against gas. Do it once, and it keeps paying you back for fifteen-odd years.
