Daikin EKHHP315 price (2026)
Modelled estimate, checked 23 September 2026: built from published before-rebate installed prices for this model, not Daikin's list price and not a quote. The STC discount is 16 certificates for a 2026 install in zone 3, which covers Sydney, Brisbane, Adelaide and Perth; Melbourne, Canberra and Hobart earn more, at the $40 clearing house cap. From 1 January 2027 the same system earns about one fifth fewer certificates, so the discount falls again.
