🔥 Instant Gas Hot Water System Package Selection Guide
(Please rotate your mobile device for easier viewing)
Choosing the right instant gas hot water system package depends on your current setup, whether plumbing or gas upgrades are needed, and if any relocation or compliance work is required. Use this guide to compare package levels and find the best match for your home.
We know things don’t always go to plan — and most customers aren’t plumbers — so we’re flexible and happy to adjust your installation package if needed.
💡 Which Package Is Right for You?
IMPORTANT: All online packages are for EXTERNAL installations only. For internal installations, please request a quote.
✅ Base – For compliant replacements of existing EXTERNAL instant systems
Best for like-for-like swaps where the existing system is fully compliant. No gas line changes, electrical work, or extra plumbing.
🧰 Example: Replacing a Rinnai B26 with a Rinnai B26 on the same wall with compliant gas supply.
✅ Silver – For minor upgrades
Includes small plumbing adjustments and a new valve kit. No gas line modifications or system disposal. Designed for customers on a budget upgrading to a slightly different model.
🧰 Example: Replacing a Rheem 26 with a Rinnai B26 where the gas line is compliant but pipework needs modifying to suit and valves need replacing for warranty.
🏆 Gold – Best Seller – For standard installations
Covers everything needed for a standard upgrade: removal of old unit, plumbing changes, valves, and a tempering valve.
🧰 Example: Upgrading from an old Bosch 16P Instant to a new Bosch 16H that requires a tempering valve, with full plumbing refresh and removal of old unit.
💰 Sapphire – Best Value – For installations requiring gas upgrades
Everything in the Gold package plus gas line upgrades or a new gas main from meter to unit to ensure safe and compliant installation.
🧰 Example: Switching from a smaller capacity like a 13L to a larger 26L instant system that needs a larger gas main and full plumbing setup.
✅ Diamond – For major gas plumbing overhauls
Adds extended gas runs, upgraded regulators or meter connections and a new power point. Ideal for homes switching to gas or where old systems were severely non-compliant.
🧰 Example: Changing from electric to gas in a home with no current gas line in the right location, requiring a full line upgrade.
✅ Platinum – The ultimate package
Includes everything: relocation, extensive plumbing, and full gas installation or rerouting. Ideal for complex installs or new system placements.
🧰 Example: Moving the hot water system to the opposite side of the home and running a new gas line with full setup and all compliance.
