Heat Pumps for Australian Homes: What to Compare

• For heating and cooling rooms, compare reverse-cycle air conditioners.
• For household hot water, compare heat pump hot-water systems.
• If you need both, assess them separately because sizing, installation and usage are different.

Floor area alone is not enough. A useful quote considers climate, insulation, draughts, glazing, orientation, room use and the temperatures you want to maintain.

Australian Government guidance says an efficient reverse-cycle system can move roughly three to six units of heat for each unit of electricity it uses. That is a useful comparison point, not a promise about your bill.

Ask for the exact indoor and outdoor model numbers, rated capacity, climate-zone performance, noise information and every electrical, drainage, mounting, ducting or zoning cost.

• Compare tank size, recovery time and the number of people using hot water.
• Check noise, airflow, drainage, frost conditions and the proposed installation location.
• If winter temperatures regularly fall below 5°C, confirm the model's minimum operating temperature and cold-weather performance.
• Confirm the backup element, timer or control settings and any tariff assumptions.
• Ask what happens if the unit fails and how warranty service is provided locally.

Running cost depends on the old system, local climate, energy prices, household use and controls. A rebate or certificate can also change the upfront price without changing whether the equipment suits the home.

Require the full price first, then show each current discount separately. Confirm eligibility with the program owner before relying on it.
