Hot Water Rebates, Tariffs & Savings
With electricity tariffs in NSW and a strong local solar resource, more Tumbi Umbi households are weighing up solar hot water vs electric hot water and shifting away from gas. Federal incentives like Small-scale Technology Certificates (STCs) can reduce the effective solar hot water price / cost or heat pump hot water price / cost at the time of purchase.
