Frequently Asked Questions
What is the relief valve pressure for the Vulcan 125L electric water heater?
The relief valve is set at 1000 kPa to ensure safety by preventing excessive pressure build-up within the system.
What are the heating element power ratings available?
This water heater offers two heating element options: 1.8 kW and 3.6 kW, allowing selection based on your household's hot water demand.
What water connections are required for installation?
The unit requires Rp3/4" water connections, a standard size for typical residential setups.
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.
