Homeowners are weighing up solar hot water price and heat pump hot water price against long‑term savings and reliability. The good news is that several Australian Government incentives help bring the hot water system price down. Small‑scale Technology Certificates (STCs) effectively act as an upfront discount on eligible solar hot water systems and heat pump hot water systems, while state‑based programmes can provide a heat pump hot water rebate or solar hot water rebate for qualifying households. There are also schemes that may support an electric hot water system rebate when you replace old, inefficient models.
For Tunnel households on modest incomes and mortgages around $1,300 a month, these discounts can cut the effective solar hot water price / cost or heat pump hot water price / cost by a substantial percentage, shortening the payback period to just a few years. Combine that with solar power and smart timers or solar‑diversion controls, and you can push hot water running costs right down. Many locals are also looking at electric hot water vs gas hot water from an emissions point of view, preferring an all‑electric home that can run largely on rooftop solar.
