FAQs – High-Capacity Heat Pump Hot Water Systems

1. What size heat pump do I need for a large family?
We recommend 270L or larger for families of 4 or more. For heavy daily use, 300L–315L models provide more consistent performance.

2. Do bigger tanks use more energy?
Not with the right heat pump. High-capacity units with strong COP ratings actually heat water more efficiently than small systems used too frequently.

3. Can I still get rebates on large systems?
Yes β€” high-capacity systems often attract more STCs, which means greater upfront savings when installed by JR Gas & Water.

4. Are these systems solar compatible?
Absolutely. Reclaim and iStore units are solar PV compatible, letting you maximise your own solar power for even lower running costs.

5. How long does installation take?
Most installs are completed same-day. Our team handles everything β€” removal, setup, compliance, and walkthrough β€” with no mess left behind.
