Frequently Asked Questions
What is the maximum water supply pressure for the Rheem Compact 25L?
The pressure of the system varies depending on the presence of an Expansion Control Valve (ECV). With an ECV installed, the pressure is 960 kPa, whereas without an ECV, the pressure rises to 1120 kPa.
What type of water connections does the Rheem Compact 25L use?
Standard Rp 3/4 water connections for easy compatibility with existing plumbing.
Is an Expansion Control Valve (ECV) necessary?
Recommended to limit water pressure to 960 kPa and protect the unit. The heater can operate without an ECV up to 1120 kPa.
How long does an electric hot water system last?
Electric storage hot water systems typically last around 8–10 years, and longer with regular servicing and anode replacement.
How do electric hot water systems work?
An electric hot water system heats water using an electric element inside an insulated storage tank, keeping hot water ready for use — a simple, reliable and affordable option.
Is gas or electric hot water cheaper?
Standard electric is usually the most expensive to run, and gas is often cheaper. A heat pump is the most efficient electric option, using up to 70% less power than a standard electric system.
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.

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.
