Why a Heat Pump?

Heat pumps cost more upfront, but the running cost gap pays it back fast. For most households the maths is in your favour after three to five years.

Less electricity

Uses about a third the power of a standard electric storage system for the same hot water output.

$700+

Saved per year

Typical 4-person household, comparing heat pump to standard-rate electric storage. Saving is smaller if you're already on Ergon Tariff 33.

$6.7k+

Saved over 10 years

Lifetime saving versus standard electric — even before you factor in the STC rebate at install time.

Running cost figures compare a heat pump against standard-rate electric storage for a typical Capricorn Coast household. If you’re already on Ergon Tariff 33, the gap is smaller — typically $150–$500 per year (~$1,500–$5,000 over 10 years). Your actual saving depends on hot water habits, tank size, and tariff. We’ll walk you through the numbers on the quote.

The STC rebate

You don’t do the paperwork

The federal government issues Small-scale Technology Certificates (STCs) for eligible heat pump installs. Each certificate has a market value — currently around $450 for the systems we install.

We handle the rebate paperwork through our Green Bank partnership and net the value off the price you see. No forms, no waiting, no chasing a refund.

STC value moves with market price — figure quoted reflects April 2026 spot price. If the value shifts before your install, we’ll let you know.

Tight upfront budget?

Standard electric storage is still a fair choice

If you can’t spend the heat pump premium upfront, a quality electric storage system is honest value. From $1,950 installed, same-day service available.
