How does a storage hot water system work

Types of systems
Storage hot water systems come in two types, one being electrically heated and the other; gas heated. When deciding on which system will better suit your home you must first establish whether there is gas already present on the property. It's no big deal if there isn't, it will just have an additional cost to have the gas fed to your home.
In order to determine what size hot water system you will need please refer to the below table.

Please Note: The above table is to be used as a guide only and you should always consult with your local plumber or hot water expert before making your purchase.
How they work
Both systems work relatively the same way. The water is brought into the tank and heated by either elements located in or around the tank, or by a burner located at the bottom of the tank. The water is kept at a constant >60°C to help stop the growth of Legionella as well as being readily available when you need hot water.
