With around 2,413 dwellings and an average household size of 2.7 people, reliable, energy efficient hot water is a big deal for local families.

Across 3158 there are 2,374 separate houses, most with three or four bedrooms, so hot water demand is steady, especially for families with kids and older relatives living under one roof. Many locals already have rooftop solar, so options like solar hot water vs electric hot water, or heat pump vs solar hot water, are now part of normal renovation conversations. A modern system also makes it easier to move towards an all-electric home and away from gas.
Average annual bill savings for typical upgrades in Upwey can look like: • Old electric to heat pump hot water system: $450–$900 per year • Gas to heat pump hot water: $350–$750 per year • Gas to solar hot water system: $300–$700 per year • Old electric to modern electric hot water system run on solar: $250–$600 per year

Interest in efficient hot water VIC-wide is growing, and Upwey is no exception. Many households are weighing electric hot water vs gas hot water and asking whether a heat pump hot water system or solar hot water system will deliver the best mix of comfort and savings. The good news is that several Australian Government and Victorian programs can help bring the heat pump hot water price / cost or solar hot water price / cost down. Small-scale Technology Certificates (STCs) effectively act as an upfront discount on approved heat pump and solar hot water systems, while state-based schemes can offer a dedicated heat pump hot water rebate, solar hot water rebate or electric hot water system rebate for eligible homes.
For many Upwey households, these hot water rebate vic programs can reduce the installed cost of a new unit by a substantial percentage, often shaving thousands off the invoice.
