The Problem

Your Old Hot Water System Is Bleeding Money

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

Here's what most people don't know:

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.

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.

The $3,600 Total Comfort Switch

Everything Included. One Fixed Price. No Surprises.

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.

What Our Customers Say

★★★★★

We were paying a fortune to run our old electric tank. Modern Hot Water Co. changed it over in one day, handled the rebate paperwork, and our next bill was noticeably lower.

S.M., Southport

Lower bill on next cycle

★★★★★

The fixed price was the big thing for us. No mucking around, no weird add-ons on the day, just a straight $3,600 install and hot water back that afternoon.

D.K., Robina

$3,600 install, no surprises

★★★★★

Our old unit died on a Saturday morning. They diagnosed it fast, gave us a clear replacement option, and had a new system in before the kids' bath that night.

L.T., Burleigh Heads

Emergency Saturday replacement

★★★★★

We kept putting it off. In hindsight that was dumb. The new system is quieter, cleaner, and our power bill dropped straight away.

J.R., Helensvale

Immediate bill drop

★★★★★

The rebate part was what scared me. They handled all of it. One call, one install, done properly.

A.P., Palm Beach

Rebate paperwork handled

★★★★★

We wanted the cheap option at first. Glad we didn't. The heat pump made way more sense once they showed us the running costs.

M.C., Nerang

Chose lower total ownership cost

Still On The Fence?

Let's Address That.

I'll just wait until my current system dies
By then you'll face an emergency bill of $2,000-$4,000+, plus days without hot water while you scramble. Installing now means you choose when, on your terms, at a fixed price.
$3,600 is a lot of money
Your old system is costing you $700-$900/year to run. A heat pump costs roughly $150-$250/year. The $500+ savings means the system pays for itself in 6-7 years — then it's pure profit for years after that.
Can't I just get a cheap electric replacement?
A cheap electric tank is cheaper to buy but much more expensive to own. Over 10 years, the running-cost difference alone can wipe out the upfront saving and leave you thousands behind.
How do I know it'll actually save me money?
Heat pumps use the same technology as your air conditioner in reverse. They move heat instead of generating it. It's physics, not a sales pitch — and 500+ Gold Coast installs back it up.
What if it doesn't suit my property?
That's exactly what the eligibility check is for. We assess whether your job looks standard before committing. If it isn't, we tell you upfront — no surprises.
I don't trust tradies with rebate paperwork
We process heat pump rebate paperwork all the time. The rebate is applied upfront — you don't fill out forms, chase approvals, or wait for money back.

Still Scrolling?

Here's What Waiting Is Actually Costing You

Every month you keep your old system: +$65-$75 in unnecessary electricity costs
Every year you delay: around $100 less in government rebates
Every day you wait: one day closer to an emergency breakdown and a $2,000+ scramble
Installing now means you choose the timing, not your failing system
