Traditional Hot Water System
The traditional type of hot water system consists of a large tank that heats and stores the water. It’s often the most affordable choice and can work ideally in houses with a large hot water usage. The tank should be cleaned yearly and with proper maintenance can last for up to 12 years. This type of hot water system is sized based on the number of people in your household.
Continuous Hot Water System
If you’re looking at an option that’s more energy efficient than a conventional model, a tankless version is a good choice. It heats water using water filled coils and can heat the water on demand so it’s always available. This option is nice for large families and for natural gas hook-ups. Electrical versions may require an upgrade with installation. This type of hot water system is sized based large households. For example a family of four will probably require a 125–160L tank however this depends on other factors too.
Heat Pump Hot Water System
This kind of hot water system uses heat from the air and the ground to heat your water. Also called a hybrid hot water system, it costs more for installation, but can save you up to 60 percent on your energy bills, making it a cost saving investment over time. This kind of hot water system doesn’t operate well in colder areas and requires several feet of clearance for installation, as it’s usually placed on top of an appliance. For example a family of four will probably require a 270-315L hot water system however this depends on other factors too.
Solar Hot Water System
A solar hot water system heats hot water by using solar panels that are usually placed on the roof of your house. The absorb heat from the sunshine and transfer it into the hot water system, where it’s turned into hot water. Solar hot water heaters are ideal for warm, sunny places, but may not work as efficiently if it’s cloudy or overcast. They are also more expensive than other types to install but could save you some money on your energy bills in the long run. This type of hot water system is sized based on the number of people in your household. For example a family of four will need about four square metres of solar collector and a 300–360L tank. This is the average but specific details will need to be considered.
