Heat Pump Hot Water Savings Calculator
Estimate an indicative annual saving range from replacing a gas or electric resistive hot water system with a heat pump system.
Assumptions
Indicative current annual hot water running cost scales with household size and current system type · heat pump systems typically use 55–70% less energy than resistive storage, giving proportionate bill savings. Actual savings depend on your tariff, climate and hot water usage pattern.

02Methodology
How we estimate hot water savings.
We scale an indicative current running cost by household size and system type, then apply a typical efficiency-gain range for heat pump systems relative to resistive or gas systems. VEU/incentive eligibility for the upgrade itself is assessed separately.
