Across postcode 2097, efficient hot water is steadily taking off. Average households of nearly three people typically run showers, laundry and dishwashers daily, so hot water energy use can easily account for a quarter of total electricity use in a typical home. Locally, we see strong interest in heat pump vs solar hot water, especially from families looking to electrify and make the most of rooftop solar. Brands like Rheem heat pump hot water, Sanden heat pump and Rinnai solar hot water are popular choices, along with Chromagen solar hot water for both houses and larger apartment blocks.
When it comes to savings, a well‑designed system can make a real difference:
• Old electric to heat pump hot water installation: save roughly $400–$800 per year on bills. • Gas to heat pump hot water system: save around $300–$700 per year, especially in all‑electric homes. • Gas to solar hot water installation: often $300–$600 per year off energy costs. • Old electric to modern electric hot water installation with rooftop solar: typically $250–$500 per year in savings.
In Collaroy, Rheem solar hot water and Rinnai solar hot water are common on established homes, while premium options like a Sanden heat pump are popular with sustainability‑focused renovators chasing the most efficient hot water system and very low running costs.

Hot Water Rebates, Tariffs & Savings
For Collaroy households, the numbers stack up even better once rebates are factored in. Australian Government Small‑scale Technology Certificates (STCs) can reduce the upfront solar hot water price / cost or heat pump hot water price / cost, and NSW hot water rebate programs often support efficient upgrades too. Depending on the system, a solar hot water rebate, heat pump hot water rebate or electric hot water system rebate can slice a substantial percentage off the installed hot water system price, bringing quality brands like Rheem solar hot water, Chromagen solar hot water or a premium Sanden heat pump within reach. For many homes, that means hundreds of dollars a year off bills, with payback periods shrinking further when you pair an energy efficient hot water system with rooftop solar and smart timers or solar‑diversion controls.
Whether you need hot water installation for a new build, hot water repair on an older unit, solar hot water repair, or a full solar hot water tank replacement, it pays to compare heat pump vs solar hot water carefully. The right choice for your place will depend on roof space, existing wiring, tariffs and whether you want an all‑electric home.
