Over the life of a system, the annual hot water energy savings can easily reach hundreds of dollars, especially when paired with rooftop solar.
In 4818, most homes are separate houses with three or four bedrooms, so hot water demand is steady – showers, laundry and dishes all add up. Hot water can account for 20–30% of a typical home’s energy use, which is why more locals are asking about the most efficient hot water system for their situation and comparing heat pump vs solar hot water, or solar hot water vs electric hot water. Brands like Rheem heat pump hot water, Sanden heat pump units, Rinnai solar hot water and Chromagen solar hot water are all popular choices for an energy efficient hot water system in QLD.

Hot Water Rebates, Tariffs & Savings
Cosgrove homeowners are increasingly replacing old gas or resistive electric units with efficient options such as a heat pump hot water system, a new solar hot water system or a well‑sized electric hot water system backed by solar. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible systems across QLD and effectively act as an upfront discount off the hot water system price or solar hot water price / cost. On top of that, state programmes can offer a heat pump hot water rebate, solar hot water rebate or electric hot water system rebate, all of which help bring the overall heat pump hot water price / cost down. For many Cosgrove households, these hot water rebate QLD schemes can shave a substantial percentage off the installed hot water system cost and cut payback periods to just a few years. Combine that with timers, smart tariffs or solar diversion, and a modern electric hot water vs gas hot water setup can deliver very low running costs.
