In Perwillowen QLD, more residents are weighing up heat pump vs solar hot water, or even solar hot water vs electric hot water, as they move away from gas. Federal incentives like Small‑scale Technology Certificates (STCs) apply to eligible solar hot water heating systems and many heat pump units, effectively reducing the solar hot water price / cost or heat pump hot water price / cost at the point of sale.
