- Your electric or gas hot water system is near the end of its life
- You want to cut energy use and move away from gas
- You have, or are planning, rooftop solar to power it
- Your current heating costs keep climbing each winter
- You're chasing available efficiency rebates while they last
What affects your heat pump quote
No one-size-fits-all pricing. Here's what shapes an honest quote:
Indoor/outdoor placement
Heat pumps need airflow and a sensible spot for the outdoor unit.
Cold-climate performance
Units rated for low temperatures cost a little more but hold output in winter.
Electrical and plumbing changes
Swapping from gas or a different system may need circuit or pipe work.
Rebates applied
Eligible rebates can significantly reduce the net price.

More about heat pumps in Melbourne
A heat pump moves heat instead of making it from scratch, which is why it can deliver several units of heating for every unit of electricity it draws. That efficiency is the whole appeal, but only if the unit is sized for your real demand. An undersized hot water heat pump leaves you cold by the third shower; an oversized heating system wastes the money you spent. We size around how your household actually lives.
Hot water, heating, or both?
Heat-pump hot water is usually the easiest, highest-return first step, it replaces a big, constant energy load with a far more efficient one. Heat-pump (reverse-cycle) space heating is the next move, especially when you're already replacing an ageing gas heater. We'll tell you which order gives the best payback for your home rather than upselling everything at once.
What we install
Integrated and split heat-pump hot water systems, and reverse-cycle heat-pump heating and cooling. We choose units with reliable Australian support and cold-weather performance suited to Victorian winters, since some budget models lose output on frosty mornings.
Victorian seasonal note
A heat pump's efficiency dips on the coldest mornings, which is exactly when Victorian homes need the most heat and hot water. Choosing a cold-climate-rated unit and sizing with winter, not summer, in mind is what keeps the showers hot in July.
Heat Pumps FAQs
How much can a heat-pump hot water system save?
A heat-pump hot water system typically uses around two-thirds to three-quarters less energy than a conventional electric storage tank. The exact saving depends on your usage, tariffs and whether it runs on solar.
Do heat pumps work in cold Melbourne mornings?
Yes, but performance varies by model. We fit cold-climate-rated units that hold their output at low temperatures, so you're not left short on the frostiest days.
Are heat pumps noisy?
They have an outdoor fan and compressor, so there is some noise, similar to an air conditioner's outdoor unit. We position them away from bedrooms and neighbours' windows to keep it unobtrusive.
Can I run a heat pump on my solar panels?
Absolutely, it's one of the best solar pairings. Put a heat-pump hot water system on a daytime timer and it heats your water largely on free rooftop power.
Is there a rebate for switching to a heat pump?
Victorian and federal efficiency programs have supported heat-pump hot water and heating. Eligibility and amounts change, so we confirm what currently applies to your job.
