A hot water heat pump uses roughly a third of the electricity of an old resistive element and replaces a gas storage unit entirely.

Excellent service! The team arrived on time and completed the installation efficiently and up to scratch. Everything was done neatly, with great attention to detail. Ryan and Jack are top blokes and easy to deal with. Highly recommended!

Absolutely fantastic service and work done! The boys were super accommodating, answered any questions I had without a problem, left everything neat and tidy and overall did an amazing job installing our battery and inverter. Cannot recommend enough.

Zak and Ryan did a amazing job. Even with the obstacles of a double story home with a internal switch board they persevered in the heat and got the job done. Thanks guys we realy appreciate your work and polite attitude.

Ryan and Jack did a great job doing the electrical work on my new 4 head split system. They got the job done in no time, and my split systems were up and running. Once connected, Ryan made sure all 4 heads were working. Thanks guys, great job!

We assess household demand, the existing service, switchboard capacity, available space, pipe runs and practical unit positions before recommending a heat pump. The quote covers the agreed electrical work, installation, commissioning and rebate paperwork. For system types, sizing, efficiency and changeover details, see the full detail on hot water heat pumps.

East of Springvale Road, Donvale's blocks run to about one acre, and the house is often a long way from the street and the switchboard. That affects hot water work. A heat pump placed near the bathrooms may need a long cable run back to the board, sized for the distance, while on the smaller western blocks the run is short and simple.

Postcode 3111, where Donvale is the only locality, had seen 400 air source heat pumps and 272 solar water heaters installed between 2001 and September 2026. With 86.8% of occupied dwellings separate houses and 43.5% owned outright at the 2021 Census, most owners have room for an outdoor unit and plan to stay long enough to recover its cost. Gas reaches streets in Donvale, and switching from gas means capping the line. The network operator is United Energy or AusNet Services depending on your street, and either one handles meter changes for timed hot water.
One visit, one plan, one crew, from first look at your switchboard to the final walkthrough.
We visit, check your switchboard and capacity, and listen to how you live.

One plan optimised for cost, comfort and what your family needs next, with every rebate you're entitled to worked out for you.
Buy in stages. Plan it as one system.
Luke's own crew installs, cleans up and walks you through every app and switch.

Federal and state rebates can cover a serious chunk of your upgrade. We work out what you're eligible for and handle the paperwork.

Everything immediately around Donvale, including Blackburn North, Doncaster East, Mitcham and Nunawading. We treat the group as one working area rather than separate bookings.
The council is Manningham and the postcode is 3111. Ordinary work here needs no council permit, only licensed work and a safety certificate.
They run at roughly the level of a fridge compressor, but the sound carries outdoors at night. Siting away from bedroom windows and neighbouring boundaries solves it, which is why we walk the site before quoting.
Tell us about your current hot water service and household demand. We’ll assess capacity, placement and connection requirements, then provide a clear heat pump quote. Book an assessment or call our Boronia crew to discuss the changeover.
