What type of system is this?

• direct hot water fed via cold water storage cistern (CWSC).

• indirect hot water fed via cold water tank

• direct hot water fed via cold water cistern

• indirect hot water fed via cold water storage (CWSC) cistern

What is the primary function of a cold water storage cistern (CWSC)?

• To directly heat water for household use.

• To store water and distribute it indirectly to heating systems ie taps, hot water cylinder.

• To filter and purify water before it is used.

• To provide direct drinking water to taps.

How does an indirect hot water system differ from a direct hot water system?

• Indirect systems use a separate heat source i.e. a boiler, while direct systems use emersion heaters in the cylinder.

• Direct systems are more energy-efficient than indirect systems.

• Indirect systems can only be used in commercial settings.

• Direct systems require a cold water storage cistern.

Which component is essential for the operation of an indirect hot water system?

• A direct connection to the main water line.

• An external boiler or heat exchanger.

• A built-in water purification system.

• None of the above.

which of the following uses gravity to increase or decrease water pressures?

• combination boiler

• hot water from a copper cylinder fed via a CWSC

• unvented hot water cylinder fed via a cold water cistern

• hot water through a water heater
