FAQs

Frequently Asked Questions

What is the hot water delivery capacity of the Rheem 400L Electric Water Heater?

The unit provides 400 litres of hot water, suitable for large households with high daily demands.

What are the available kW ratings for this model?

Heating elements are available in 3.6 kW and 4.8 kW, allowing selection based on your household’s hot water needs.

What is the relief valve pressure for the Rheem 400L?

The relief valve is set at 1000 kPa, ensuring safe and efficient operation in accordance with Australian standards.

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.
