Glen Waverley's climate is mild, so a quality standard unit is fine. The key here is capacity: large homes and households need a tank sized so they don't run cold, and many homes still run gas, where switching brings the biggest gains.
- Size up for a big household — a larger tank (300 L+) and an adequately-sized heat pump avoid running cold.
- Leafy streets: site the outdoor unit clear of trees, away from bedrooms.
- Older homes on gas may need a switchboard change; count the supply-charge saving.
- A 5-year warranty and accredited installer are required for the Victorian rebates and STCs.

What size heat pump do I need for a large Glen Waverley home?
Bigger than the standard family setup. Glen Waverley's large homes and households use a lot of hot water, so a 300 L+ tank with an adequately-sized heat pump avoids running cold at busy times. The mild climate means a quality standard unit is fine. The saving over an old electric tank is large — often well over $500 a year — and coming off gas drops the supply charge too. Victoria's rebate stack (Victorian Energy Upgrades + Solar Victoria hot water + federal STCs) can total around $2,600 off, far more than NSW.
How much does a heat pump hot water system cost in Australia?
Most systems cost between $2,000 and $4,500 installed before rebates. Federal STCs come off at the point of sale Australia-wide, and most states add their own rebate (for example Victorian Energy Upgrades or the NSW Energy Savings Scheme), so the price you actually pay is often well below that range.
How much can I save on running costs?
A heat pump uses roughly a third of the electricity of a conventional electric element. For a family of four that can cut hot-water running costs from around $700 a year to under $250 — and close to zero if you run it on solar during the day.
Do heat pumps work in cold Victorian winters?
Yes, but quality matters. Cheaper units can fall back on their electric element on frosty mornings, which reduces savings. In colder areas choose a unit rated for low ambient temperatures, such as a CO2 split system.
