Hot Water Rebates, Tariffs & Savings
Right now, there is strong interest in Tiwi in replacing old gas or electric hot water with efficient options – from solar hot water vs electric hot water comparisons, to electric hot water vs gas hot water for all‑electric homes. Federal incentives such as Small‑scale Technology Certificates (STCs) apply to eligible heat pump and solar hot water systems, effectively acting as a solar hot water rebate or heat pump hot water rebate that is usually taken off the upfront hot water system price / cost. On top of that, NT homeowners can often access state‑based hot water rebate NT style discounts for approved systems, including an electric hot water system rebate in some programs.
These incentives can trim the heat pump hot water price / cost or solar hot water price / cost by a substantial percentage, cutting payback periods down to just a few years, especially if you already have rooftop solar. Add in simple tricks like timers or solar‑diversion controllers and your solar hot water vs electric hot water decision can lean even more in favour of an efficient, low‑running‑cost setup.
If your current unit is rusty, running out of hot water or due for a solar hot water tank replacement or hot water repair, it is a good time to look at hot water NT options. Whether you need hot water installation on a new build, electric hot water installation in a unit, solar hot water repair on an older chromagen solar hot water or rheem solar hot water system, or a full upgrade to an energy efficient hot water system, working with experienced local installers matters.
Tiwi’s strong sun and growing focus on sustainability mean efficient hot water systems are a simple way to reduce bills, cut emissions and future‑proof your home.
