The Problem
Most Gold Coast homeowners don't realise their hot water system is the single biggest electricity cost in their home.
25%
of your electricity bill goes to heating water — more than air conditioning, cooking, or lighting
$800+
per year to run a conventional electric hot water system on the Gold Coast
10 yrs
That's $8,000+ wasted on inefficient hot water over the average system lifespan
Conventional electric hot water systems use a resistance element to heat water. It's the same technology as a kettle. Cheap to buy, insanely expensive to run.
A heat pump hot water system works differently. Instead of generating heat, it moves heat from the air into water — like a reverse air conditioner. The result? It uses up to 75% less electricity for the same amount of hot water.
That means your $800/year hot water bill drops to around $200/year. You save $500+ per year, every year, for the 15+ year life of the system.

Interactive Calculator
Compare a typical Gold Coast household running an older system against a heat pump with much lower yearly power costs.
What the bars mean: the red bar shows the estimated total cost to keep your current system running for 10 years. The green bar shows the estimated total cost of switching to a heat pump over the same period, including the $3,600 install and much lower yearly running costs.
Based on a typical Gold Coast 3–4 people household and current energy-price benchmarks.
Estimated yearly bill reduction
$1,000
Estimated cost avoided (10 yrs)
$6,400
Estimated payback period
~4 years
That's roughly $1,000 back in your pocket every year compared with keeping your current electric storage tank.
Over 10 years, this example puts the heat pump at about $6,400 ahead overall.
The Smarter Choice
75%
Heat pump hot water systems extract heat from the air instead of generating it. Same hot water, fraction of the electricity.
$500+
Most Gold Coast homeowners save $300-$500 per year on electricity after switching from electric or gas hot water.
~$1,000
STC rebates reduce the upfront cost by approximately $1,000+. We apply the discount at point of sale — no paperwork for you.
15+ yrs
Premium heat pump hot water systems last 15+ years with proper maintenance. That's $7,500+ in energy savings over their lifetime.
3-5 hrs
No weeks of waiting. We remove your old system, install the new one, and have hot water running the same day.
24/7
Heat pump hot water systems work in all weather — day, night, rain, or shine. The Gold Coast climate makes them even more efficient.

The $3,600 Total Comfort Switch
For most Gold Coast homeowners, the real risk isn't the $3,600 install — it's spending another 12 months feeding an old system that costs more to run and could still fail on you.
