Hot Water Rebates, Tariffs & Savings
There is growing interest in Hidden Valley in replacing old gas or electric hot water with efficient options such as heat pump hot water, modern electric hot water systems and solar hot water systems. Homeowners can often tap into a mix of Australian Government and NT hot water rebate programs. Federal incentives like Small‑scale Technology Certificates (STCs) effectively lower the solar hot water price / cost and heat pump hot water price / cost at the point of sale.

For many Hidden Valley homes, these hot water rebate NT incentives mean payback periods can drop to just a few years, especially when a heat pump vs solar hot water comparison is done alongside existing or planned rooftop solar. Typical savings from an efficient hot water upgrade can easily reach hundreds of dollars per year. Using timers or solar‑diversion controls to run a solar hot water vs electric hot water system during the middle of the day can further boost savings and make your hot water NT setup an energy efficient hot water system that works with, not against, your solar.
If you are weighing up electric hot water vs gas hot water, or deciding between heat pump vs solar hot water, now is a smart time to look at your options.
