Warranty
iStore’s December 2025 owner’s manual gives 5 years parts and labour on the glass-lined tank, refrigeration system and electrical parts, for units made and installed from 1 October 2022. It also requires a 500 kPa pressure reduction valve; installing without one voids the warranty.
Support in Australia
Warranty registration is on iStore’s heat pump website.

Our take
A straightforward plug-in heat pump with one warranty term covering the tank, refrigeration and electrics. Ask for the current data sheet, since iStore’s documents don’t all agree.
Before you buy
- Check the exact model is on the Clean Energy Regulator’s register, which sets its STCs, and, in Victoria, eligible for the Solar Victoria rebate if you want it.
- Plan where it goes. A heat pump needs airflow and makes some noise, so keep it away from bedroom windows and your neighbours’ fence.
- Ask about your water. Warranties can exclude very hard or salty water, and unfiltered bore or rain water, so check yours is covered.
- Compare quotes from hot water retailers near you, and read heat pump vs solar hot water.
