Things to consider when choosing a hot water heater.
Electric storage hot water systems – the most common type in Victoria – heat water with an element in the bottom of the unit and store it in an insulated tank, ready for use throughout the day. Electric hot water systems are the cheapest to buy but the most expensive to run.
A high efficiency gas hot water system is one of the most economical types of water heaters, when operated on natural gas. Gas and electricity prices are rising, so if you have a conventional gas or electric hot water system that needs replacing, consider a more efficient gas or solar hot water system.
A solar hot water system is more expensive to buy and install, but the running costs will be significantly lower. The cheapest and most environmentally friendly type of water heating to run is natural gas-boosted solar.
A heat-pump water heater uses heat from the surrounding air to heat water in a storage tank. A heat-pump water heater uses much less electricity than an electric storage water heater, but are generally better suited to warmer climates.

Your water heater supplier will be able to help you choose the right-sized system.
Regardless of the type of hot water system that you choose, simple installation tips will help you to save energy and money.
Choosing a hot water system can significantly impact your energy and money savings. It's important to ask your hot water retailer or plumber the right questions when you're making your decision.
