Hot Water System Quiz

What is required for a standard, gravity-fed hot water system to function effectively?

• High head height between the cold water storage cistern and the hot water cylinder

• Low head height between the cold water storage cistern and the hot water cylinder

• High water temperature

• Low water temperature

What happens when the head height in a gravity-fed hot water system is increased?

• The pressure decreases

• The pressure increases

• The flow rate decreases

• The flow rate increases

How does increasing the pipe diameter affect the flow rate in a hot water system?

• The flow rate decreases

• The flow rate remains the same

• The flow rate increases

• The pressure decreases
