Frequently Asked Questions
How does the continuous flow feature benefit commercial applications?
Continuous flow technology ensures hot water is available instantly, even during peak usage. This is particularly valuable for commercial settings such as hotels, restaurants, health facilities, and multi-residential developments.
What should I do if the digital display is not functioning correctly?
If the digital temperature display is not operating as expected, contact a qualified hot water technician. They can diagnose and resolve any issues quickly to restore proper system performance.
How energy-efficient is the Rheem Tankpak External TPE01 compared to traditional systems?
The Tankpak External TPE01 is more energy-efficient than many traditional commercial hot water systems. Its combination of storage and continuous flow technology helps reduce energy loss, lower running costs, and minimise environmental impact.
How much does a new hot water system cost?
The cost of a new hot water system depends on the type and size. Electric storage systems are the most affordable upfront, while heat pump and solar systems cost more but save on running costs and may qualify for rebates. Call SunCity Hot Water on 1300 728 122 for an all-inclusive supplied-and-installed quote on the Rheem Tankpak External TPE01.
How long does a hot water system last?
Most hot water systems last 8–12 years. Electric storage systems typically last 8–10 years, while heat pump and solar systems can last 15 years or more with regular servicing.
What size hot water system do I need?
As a guide, 1–2 people suit 125–160L, 3–4 people (a family of four) suit 250–315L, and larger households suit 400L. Continuous-flow gas units are sized by hot water flow rate instead. SunCity will help size the right system for your household.

SunCity Hot Water quotes all-inclusive pricing — supply, installation by licensed plumbers and electricians, tempering and pressure-relief valves, removal of the old unit, QBCC fees and GST — with no hidden extras. Call 1300 728 122 for a fast quote.
