What a Rheem Costs Installed
The unit is only part of the bill. A licensed plumber (and an electrician for some jobs) removes the old system, fits the new one and handles compliance. For a straight swap, the Yellow Pages Australia hot water cost guide (updated May 2026) puts labour at $500 - $800 (swap an electric storage unit for another) and $300 - $700 (swap a gas unit for another). Changing type costs more, because it can mean new wiring, a new circuit or moving the system.

Is a Rheem Heat Pump Worth the Extra?
A Rheem heat pump costs more to buy ($3,449 to $5,263 for the unit) but is far cheaper to run than electric or gas, at around $200 - $400 a year against $1,200 - $1,800 for electric storage. Federal certificates typically take $500 - $800 off at the point of sale, and several states add a rebate on top, which closes much of the gap.
Replacing gas in Victoria? From 1 March 2027, Victorian law requires a mains gas hot water unit that fails in an existing home to be replaced with an electric one. Limited exemptions apply, for example where there is no room for an electric unit. See what replacing gas hot water in Victoria costs.
