Building Services Engineering Systems Quiz

What is the purpose of a magnetic system filter?

• To regulate the flow of water in the heating system

• To maintain a pre-set temperature in the underfloor heating manifold

• To combat the damaging effects of system debris and pollutants

• To control the flow of water from the boiler to the hot water storage cylinder

What is the advantage of a combi boiler system?

• It can provide hot water and central heating at the same time

• It does not require a separate cylinder for hot water

• It has a high flow rate to meet a high demand for water

• It can be finely controlled by a cordless programmable thermostat unit

What is the disadvantage of a combi boiler system?

• It has a separate boiler for hot water

• It does not require a cordless programmable thermostat unit

• It has a low flow rate to meet a high demand for water

• It cannot provide hot water and central heating at the same time

What is the function of a fully pumped system's circulator pump?

• To combat the damaging effects of system debris and pollutants

• To divert central heating water to heat up fresh water from the mains water feed

• To control the flow of water from the boiler to the hot water storage cylinder

• To maintain positive pressure throughout the system

What is the purpose of a two-port motorised valve in a fully pumped heating system?

• To control the flow of cold water from the boiler to the hot water storage cylinder

• To regulate the flow of water in the heating system

• To close off the flow of water to a heating zone when its heat requirement is satisfied

• To divert central heating water to heat up fresh water from the mains water feed

What is the main disadvantage of underfloor heating?

• The heat is concentrated at floor level

• The floor becomes the heat emitter when it is heated up by pipework

• It takes time for heat to generate or dissipate when the system is turned on or off

• It provides a lower, more even temperature

What is the advantage of underfloor heating?

• It takes time for heat to generate or dissipate when the system is turned on or off

• It provides a lower, more even temperature

• The heat is concentrated at floor level

• The floor becomes the heat emitter when it is heated up by pipework

What is the purpose of a kitchen plinth fan convector heater?

• To divert central heating water to heat up fresh water from the mains water feed

• To fit into the plinth below a kitchen unit and free up wall space

• To provide a lower, more even temperature

• To maintain a pre-set temperature in the underfloor heating manifold

What is the function of a radiator control valve?

• To control the flow of water from the boiler to the hot water storage cylinder

• To regulate the flow of water in the heating system

• To open and close depending on the room's air temperature

• To divert central heating water to heat up fresh water from the mains water feed

What is the purpose of a three-port motorised valve in a fully pumped heating system?

• To close down the boiler and pump until there is a demand for heat for a heating zone

• To control the flow of water from the boiler to the hot water storage cylinder

• To regulate the flow of water in the heating system

• To divert central heating water to heat up fresh water from the mains water feed
