pp5 Heating System Components Quiz

What are low loss headers used for?

• To allow multiple circuits and multiple boilers without affecting each other

• To control hot water temperature

• To prevent freezing of vulnerable parts

• To govern the temperature of the primary water

What is the purpose of a cylinder thermostat?

• To control the flow of water to both the heating and hot water circuits

• To govern the temperature of the hot water

• To upgrade a non-compliant system to give control over primary flow temperature

• To prevent vulnerable parts of the system freezing

What is the purpose of a boiler thermostat?

• To control the flow of water to both the heating and hot water circuits

• To govern the temperature of the primary water from the boiler

• To prevent freezing of vulnerable parts

• To allow independent timed control of both the hot water and the central heating

Where should a room thermostat be situated?

• On an outside wall

• 1.5m up a wall and approximately 3m away from a heat source

• Near the boiler

• In the kitchen or airing cupboard

What is a two-port motorised valve commonly known as?

• Zone valve

• Diverting valve

• Mid-position valve

What is the function of a diverter valve in a boiler?

• To control the flow of water to both the heating and hot water circuits

• To divert the flow of water between the heating and hot water circuits

• To prevent freezing of vulnerable parts

• To govern the temperature of the primary water

What is the purpose of a zone valve in a heating system?

• To control the flow of water to specific zones in the heating system

• To govern the temperature of the hot water

• To prevent vulnerable parts of the system freezing

• To upgrade a non-compliant system to give control over primary flow temperature

What is the role of a mid-position valve in a heating system?

• To control the flow of water to the pump

• To allow independent timed control of both the hot water and the central heating

• To govern the temperature of the primary water

• To prevent freezing of vulnerable parts

What is the function of a pressure relief valve in a boiler?

• To control the flow of water to both the heating and hot water circuits

• To release excess pressure from the system

• To prevent freezing of vulnerable parts

• To govern the temperature of the primary water

What is the purpose of a thermostatic radiator valve?

• To control the flow of water when temperature is reached

• To govern the temperature of the hot water

• To prevent vulnerable parts of the system freezing

• To upgrade a non-compliant system to give control over primary flow temperature
