Switching to a heat pump hot water system is one of the most cost-effective energy upgrades a Victorian household can make. Unlike traditional electric or gas storage heaters that burn energy to generate heat, a heat pump extracts warmth from the surrounding air — using up to 75% less electricity to deliver the same volume of hot water.

Upgrade Energy supplies and installs heat pump hot water systems across Victoria, with access to VEU rebates that can significantly reduce your upfront cost.

How A Heat Pump Hot Water System Works

A heat pump hot water system operates on the same principle as a refrigerator — but in reverse. Rather than removing heat from a space, it absorbs heat from the ambient air outside and transfers it into your water tank via a refrigerant cycle.

A fan draws in warm outdoor air across an evaporator coil
Liquid refrigerant in the coil absorbs the heat and converts to a gas
The gas is compressed, raising its temperature significantly
Heat is transferred to the water in the storage tank
The refrigerant cools, returns to liquid form, and the cycle repeats
