Professional installation is recommended to ensure safe and correct connection to your home’s gas and water supplies. Its compact, wall-mounted design is ideal for tight spaces typical of apartments and townhouses.

Regular servicing by a qualified technician is advised to maintain efficiency and longevity. Routine checks should include inspection of gas connections, cleaning components, and servicing according to manufacturer guidelines.

FAQs

Frequently Asked Questions

What are the differences between the natural gas and propane models?

Both models provide identical performance and features. Choosing the correct model for your home’s fuel supply ensures optimal efficiency and safety.

How does Flamesafe® overheat protection enhance safety?

Flamesafe® automatically shuts down the heater if excessive temperatures are detected, preventing overheating and safeguarding your household.

Can I install the Rheem 20L unit myself?

DIY installation is strongly discouraged. A qualified professional should install the water heater to ensure safety, proper performance, and compliance with warranty conditions.

Is gas hot water cheaper than electric?

Gas hot water is often cheaper to run than peak-rate electricity, particularly for larger households. Continuous-flow gas only heats water on demand, avoiding the standby heat loss of a storage tank. Actual running costs depend on your gas rates and usage.

How does gas hot water work?

A gas hot water system burns natural gas or LPG to heat your water — either instantly as it flows through a continuous-flow (tankless) unit, or stored in a heated tank ready for use.

How long do gas hot water systems last?

Gas hot water systems typically last around 10–12 years with regular servicing. Continuous-flow units often last longer than storage models.

What size gas hot water system do I need?

Continuous-flow gas systems are sized by flow rate (litres per minute) based on how many hot water outlets run at once; gas storage systems are sized by tank capacity. SunCity will match the right unit to your household's peak demand.

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.
