Even if you are only just starting to think about a hot water installation or hot water repair, it is worth understanding the incentives. Federal Small‑scale Technology Certificates (STCs) can lower the solar hot water price / cost and heat pump hot water price / cost at the point of sale. On top of that, state programs often provide a solar hot water rebate, heat pump hot water rebate or electric hot water system rebate for eligible households, effectively cutting the system cost by a substantial percentage. In practice, that means a quality chromagen solar hot water or Rheem solar hot water system, or a Sanden heat pump, can end up costing far less upfront, while saving hundreds of dollars per year on bills. When rebates, smart tariffs and rooftop solar are combined, payback periods can be shortened significantly, especially if you use timers or solar‑diversion to run your hot water when the sun is shining. For many homes, the real hot water system price / cost over the life of the unit is dramatically lower than sticking with old gas.
If you are in Corrimal and your current unit is getting noisy, rusty or unreliable, this is an ideal time to compare options such as the best hot water system australia for your needs, from solar hot water repair and solar hot water tank replacement through to new electric hot water installation or a full heat pump hot water installation.
