• Old electric to heat pump hot water installation: save roughly $400–$800 per year on bills. • Gas to heat pump vs solar hot water: often $300–$700 per year, depending on usage. • Gas to solar hot water installation: around $250–$600 per year. • Old electric to modern electric hot water installation with rooftop solar: $250–$500 per year.
These are general ranges, but they show why so many households are comparing heat pump vs solar hot water and even solar hot water vs electric hot water boosted by rooftop PV when planning a hot water upgrade.
Pental Island has already seen 35 efficient hot water systems installed, combining heat pump and solar hot water installation projects. Installations spiked around 2009, with 16 systems in that year alone, and there has been a steady trickle of jobs in other years, including new activity in 2025. That pattern reflects growing local interest in electrification, lower running costs and moving away from gas hot water where possible. As systems age, more solar hot water repair work and solar hot water tank replacement is also appearing, alongside hot water repair on older electric units.
