Strengths
- Rated to -10 °C without an element
- Four sizes, from 150 to 340 L
Watch for
- 2 years on electrical and refrigeration parts, shorter than most brands here
- Quantum doesn’t say where the units are made
Our take
Good cold-weather ratings for an R290 unit and a size for most homes, but the short warranty on the parts most likely to fail holds it back.
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.
