Homeowners renovating older homes are increasingly choosing to go fully electric - replacing gas heating, hot water, and cooktop with efficient electric alternatives. This requires larger battery systems to support higher electrical loads.
A typical all-electric conversion replaces gas hot water with a heat pump, gas heating with split system AC, and gas cooktop with induction. This increases electricity usage but can eliminate $1,500-2,000/year in gas bills.
Going all-electric means no gas backup during power outages. Homeowners often want whole-home backup capability, plus the ability to run the home almost entirely off solar and battery to maximise energy independence.
Larger systems (15-20 kWh) are typically needed for all-electric homes. High usage (30-45 kWh/day) requires larger capacity to cover evening peaks when heat pumps and induction cooktops run simultaneously.
Work with installers experienced in all-electric conversions who can properly size systems for heat pump and induction loads. They should also handle Western Power's backup system approval process.
