Hot Water Rebates, Tariffs & Savings
All this interest in hot water NT wide is being helped along by generous incentives. For Charles Darwin households, Australian Government Small-scale Technology Certificates (STCs) reduce the upfront solar hot water price / cost and heat pump hot water price / cost. On top of that, Territory and other state-style programs often include a solar hot water rebate, a heat pump hot water rebate or even an electric hot water system rebate when you replace an old, inefficient unit. These discounts can effectively knock a substantial percentage off the hot water system price / cost, cutting payback periods significantly. When you combine rebates with smart tariffs, timers or solar diversion, a quality Rheem solar hot water, Rinnai solar hot water, Sanden heat pump or Chromagen solar hot water system can deliver hundreds of dollars a year in savings. For many homes, that makes heat pump vs solar hot water a practical choice between two excellent, energy efficient hot water options rather than sticking with electric hot water vs gas hot water.
If your current unit is ageing, unreliable or you are facing a solar hot water tank replacement or hot water repair, it is a great time to compare solar hot water vs electric hot water and look at the best heat pump hot water system options for your home.
