• Traditional warm water cylinders that get their water from a cistern that is generally located in the attic of the home. These systems generally provide their owners with a greater head of water. They generally provide a better rate of flow at the faucets. These systems require a large amount of space and therefore are not generally suitable for apartments or flats that are small, and have no attic.
• There are hot water cylinders that circulate the warm water that comes out of the boiler directly through the cylinder in place. These water cylinders are frequently chosen by landlords because they are very low maintenance ways to provide rental properties with a hot water supply that will not need frequent draining.
• There are self priming hot water cylinders that have no need for the system to have a feed system that is separate from the expansion system of the unit.
• In the indirect hot water cylinders the water will be passed through a heat exchanger that is located inside the tank. This prevents the mixing of the boiling water and the water that is in the storage vessel.

When you are choosing your hot water cylinders you have to consider exactly how much of this substance you will need on a daily basis. In most of the modern homes the normal amount used is between thirty five liters, and forty five liters, each day per person living in the dwelling. This means you will need a tank that is large enough to hold an adequate amount of water for the number of household occupants, and the number of devices that require heated water to run.

Washing machines, dishwashers, showers, and sinks, all use this substance. A home that does not have an electric dishwasher may not need as great an amount of heated water as a home that does have one.
