HW - sys components A

Which of the following best describes the layout and operational requirements of hot water system components?

• The layout includes a boiler, pipes, and radiators, and requires regular maintenance.

• The layout includes solar panels and requires no maintenance.

• The layout includes a furnace and requires annual inspections.

• The layout includes a heat pump and requires monthly filter changes.

Which of the following statements best explains the location and safety features for unvented/vented hot water systems with consideration of standard components?

• Unvented systems should be located in a well-ventilated area with safety valves.

• Vented systems do not require any safety features.

• Both systems should be installed without any consideration for location.

• Unvented systems can be installed anywhere without safety concerns.

What is the purpose of the vent pipe in an open-vented system?

• To heat the water

• To enable the expansion of hot water and act as a safety discharge point

• To cool the water

• To increase water pressure

Which component in the unvented hot water system is responsible for cutting off energy when the temperature is too high?

• Thermostat

• Pressure relief valve

• Expansion vessel

• Temperature sensor

What is the function of the Pressure relief valve in a modern UVHWSS?

• To increase water pressure

• To relieve excess pressure

• To filter impurities

• To heat the water

What is the third tier of safety in the event of cylinder thermostat and energy cut-off failure?

• Pressure relief valve

• Temperature sensor

• Manual reset

• Automatic shutdown

What is the function of a line strainer in plumbing?

• To filter out debris and protect plumbing components

• To increase water pressure

• To heat the water

• To reduce water flow

What components make up a composite valve?

• Line strainer, pressure reducing valve, expansion relief valve, non-return/check valve, isolation valve
