Which of the following describes a low-pressure hot water system?
Supplied directly from the mains
Supplied from a combination boiler
Supplied from a cistern in the loft
Supplied through a heat exchanger
In a gravity-fed hot water system, what role does the hot water cylinder play?
Heats water on demand
Stores and heats water
Supplies water directly from the mains
Acts as a pressure regulator
Which of the following is a characteristic of an indirect hot water system?
Heats water directly in the cylinder
Uses a coil or immersion heater to heat water
No stored water in the loft
Supplied under mains pressure
What is an advantage of an indirect gravity hot water system?
Higher water pressure
Consistent pressure regardless of mains supply
Requires less space
Lower risk of contamination
Which system is most likely to experience a drop in pressure if the cistern is not positioned correctly?
Direct hot water system
Indirect hot water system
Gravity-fed hot water system
Combination boiler system
What is a significant disadvantage of gravity-fed hot water systems?
A) High installation costs
B) Variable pressure
C) Requires a lot of space for storage cisterns
D) Low installation costs
In a direct hot water system, how is the water typically heated?
A) Using a coil inside the cylinder
B) Using an immersion heater in the cylinder
C) Through a combination boiler
D) By solar panels
Which of the following statements is true about a direct gravity hot water system?
A) It provides potable water at every outlet
B) It heats water on demand
C) It relies on gravity to push hot water to the outlets
D) It uses a heat exchanger to heat water
What is a common advantage of both direct and indirect gravity hot water systems?
A) Higher water pressure
B) Stored supply of hot water if mains are turned off
C) Lower installation costs
In an indirect gravity hot water system, what happens when a hot water outlet is opened?
The water is heated on demand by the combination boiler
The hot water leaves the cylinder under gravity and flows to the outlet
The mains pressure pushes the hot water to the outlet
The water is reheated before reaching the outlet
