Efficient hot water is a hot topic in Combo NSW, especially as older gas storage units and basic electric systems reach the end of their life. Homeowners are weighing up heat pump vs solar hot water and even solar hot water vs electric hot water backed by rooftop PV. The Australian Government’s Small‑scale Technology Certificates (STCs) apply to eligible solar hot water systems and heat pump units, effectively acting as an upfront solar hot water rebate or heat pump hot water rebate that can trim the solar hot water price / cost or heat pump hot water price / cost by thousands in some cases.
