Heating System Components part 2

What is the purpose of a circulator in a heating system?

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

• To collect corroded iron particles

• To ensure positive pressure in the system

• To govern the temperature of the primary water

What is the function of a two port motorised valve in a heating system?

• To govern the temperature of the primary water

• To ensure positive pressure in the system

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

• To collect corroded iron particles

Where is the cylinder thermostat situated in a hot water cylinder?

• Halfway up the cylinder

• One-third of the way up the cylinder

• At the bottom of the cylinder

• At the top of the cylinder

What is the purpose of a room thermostat in a heating system?

• To override the programmer and other thermostats

• To sense the temperature in a room and control the heating system

• To govern the temperature of the primary water

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

Where is the boiler thermostat located?

• On the boiler

• On the circulator

• On the radiator

• On the hot water cylinder

What is the purpose of a programmer in a heating system?

• To govern the temperature of the primary water

• To ensure positive pressure in the system

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

• To collect corroded iron particles

What is the function of a frost thermostat in a heating system?

• To sense the temperature in a room and control the heating system

What is the function of an inhibitor in a central heating system?

• To ensure positive pressure in the system

• To protect against scale and corrosion within the system

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

• To sense the temperature in a room and control the heating system

What is the purpose of a lock shield valve in a heating system?

• To alter the flow of water into the radiator to suit the customer's needs

• To protect against scale and corrosion within the system

• To ensure positive pressure in the system

• To collect corroded iron particles
