A heat pump hot water system works a bit like a fridge in reverse. A small compressor pulls warmth out of the outside air and moves it into the water in the tank, so it uses a fraction of the electricity a standard electric element does. Perth's mild climate suits them well, and they pair nicely with rooftop solar because you can set most units to run through the middle of the day.
This is the heat pump site of Sureflow Plumbing & Gas, a family-run team of licensed plumbers and gas fitters based in Clarkson with more than 20 years in the trade. We work right across Perth's northern suburbs from Two Rocks down to Scarborough and inland to Landsdale. We supply and install heat pumps from brands we know and trust, and we'll tell you straight if a heat pump isn't the right fit for your place.
We don't do prices over the phone. Plenty of businesses will, but that number rarely survives the real job, because nobody has looked at your power supply, the clearances, the drainage or where the old unit sits. We come out, check what's there, and give you one all-inclusive price before any work starts.

What a heat pump install involves
Swapping a hot water system isn't just unplugging one tank and plugging in the next. A proper heat pump install covers the bits you don't see as well as the bits you do:
- Safe disconnection and removal of your old unit, and we take it away with us
- Water connections done by licensed plumbers, with new tempering and relief valves fitted and set
- A level pad or base and proper drainage for the condensate the heat pump makes
- Clearances and airflow checked, because a heat pump needs room to breathe
- Licensed electricians arranged by us where your power supply needs work
- The system commissioned and tested before we leave, and the timer set to suit your household
A straight swap usually takes around three hours. A conversion from gas, a relocation or a job that needs electrical work can take up to a full day. We'll tell you which one you're looking at when we quote.
What a heat pump costs in Perth
Across Perth, a heat pump hot water system typically costs around $4,400 supplied and installed before the federal STC discount, with most jobs landing between $3,150 and $6,300. After the STC discount, typical prices drop to around $3,775. Bigger tanks, tricky access and conversions from gas cost more.
Have a look at our Perth heat pump price guide for prices by tank size, and our WA rebate guide to see how the STC discount works.
Is a heat pump right for your home?
Heat pumps suit most Perth homes, but not every one. They need a spot outside with decent airflow, they make a low hum while running, and they cost more upfront than a basic electric tank. They really earn their keep when your old electric storage unit is near the end of its life, when you've got rooftop solar, or when you want to get off gas.
If you're not sure, our heat pump vs gas guide walks through the trade-offs, and we're always happy to tell you on site if a different system makes more sense.
