Frequently Asked Questions
What is the primary application for this water heater?
This water heater is specifically designed for heating potable water. Using it for other purposes may reduce its lifespan. For applications requiring uninterrupted hot water supply, designing redundancy into the system is recommended to ensure supply in case of unit failure.
Where should the water heater be installed?
Install the water heater in a location prioritising safety and ease of maintenance. For solar water heating systems, position the unit close to the solar storage tank. Ensure flue terminals are inaccessible to people, especially children, and that flue terminals and air inlets remain free from obstructions such as shrubs.
Can this water heater be installed outdoors?
Yes, the water heater can be installed outdoors without a secondary flue. It should not be installed indoors or in confined spaces to maintain proper ventilation and safety.
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 Multipak MPE03.
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.
How much does it cost to install a hot water system?
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.
