FAQs

Frequently Asked Questions

Is the Rheem Indoor 135L Gas Water Heater an easy replacement for my current system?

Yes, this model is designed for straightforward replacement of most existing 3-star systems, enabling minimal disruption during installation.

How does the two-anode system benefit the Rheem Indoor 135L Gas Water Heater?

The two-anode system helps protect the cylinder from corrosion, thereby extending its service life and reducing maintenance needs.

Can the Rheem Indoor 135L Gas Water Heater be installed indoors?

Yes, this water heater is specifically designed for indoor installation, making it suitable for homes with limited outdoor space.

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.
