Electric Hot Water System Package Selection Guide
(Please rotate mobile device to landscape for easy viewing)
Choosing the right electric hot water system package depends on your installation needs, household size, and whether additional electrical work is required. Use this guide to compare package levels and find the best fit for your home.
Selecting the right package helps streamline installation, but we understand that needs may change, and that the purchaser isn’t a plumber. We’re flexible and can make adjustments, such as upgrading to the next package as needed.
💡 Which Package is Right for You?

✅ Base – For compliant replacements of Existing EXTERNAL installations
Ideal for direct swaps where the existing system meets compliance. No extra plumbing or electrical work included.

✅ Silver – For minor upgrades
Includes pipework alterations and a valve kit but does not include electrical modifications or system disposal. Designed for those swapping a similar system and working to a tight budget.
(EXAMPLE - Swapping a 10year old Rheem 250L with a new Rinnai 315L where the existing installation is good but requires pipework alterations to adapt the new unit and new valve set for warranty)
🏆 Gold (Best Seller) – For standard installations

(EXAMPLE - Swapping a 20year old Dux 125L with a new Vulcan 315L, Strip all down and redo the valves, pipework, drain lines, support base and dispose of the old unit)
💰 Sapphire (Best Value) – For installations requiring electrical work

(EXAMPLE - Swapping an old heat pump with a new Everhot 400L that requires a hardwired electrical connection, then strip all down and redo the valves, pipework, drain lines, support base and dispose of the old unit)
✅ Diamond – For homes needing extensive electrical work
Provides extra plumbing and electrical modifications, including a new electrical circuit, making it ideal for homes without existing wiring for an electric system.
(EXAMPLE - Swapping an old Gas System with a new Rheem 315L that needs its own dedicated electrical circuit, type then strip all down and redo the valves, pipework, drain lines, support base and dispose of the old unit)
