Hot Water Rebates, Tariffs & Savings
Homeowners in Nomans Lake are increasingly keen to replace old gas or resistive electric units with efficient options like a heat pump hot water system, a modern electric hot water system or a solar hot water system. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible systems, effectively acting as an upfront discount that lowers the solar hot water price / cost or heat pump hot water price / cost you pay. On top of that, WA hot water rebate schemes and electric hot water system rebate offers may be available from time to time, particularly for replacing inefficient units. These hot water rebate WA programmes can cut the system cost by a substantial percentage and shorten payback to just a few years, especially if you already have solar and can use timers or solar‑diversion to run your hot water when the sun is shining.
Whether you are weighing up solar hot water vs electric hot water, or comparing electric hot water vs gas hot water, it pays to look at lifetime running costs, not just the upfront hot water system price / cost. A well‑sized rheem solar hot water setup, a quality sanden heat pump or another best heat pump hot water system option can deliver hundreds of dollars a year in savings while slashing emissions. If you already have rooftop solar, using an energy efficient hot water system as a daytime load is one of the smartest ways to maximise your solar investment.
If your existing unit is rusty, unreliable or you are facing a solar hot water tank replacement or hot water repair, it is a good time to explore a full upgrade rather than just patching an old system. Experienced local installers can guide you through hot water repair vs replacement, explain solar hot water price / cost compared with heat pump hot water price / cost, and help you choose between rheem solar hot water, rinnai solar hot water, chromagen solar hot water or a premium sanden heat pump for your property.
