Boiler parts quiz

What is this?

• A radiator

• A boiler

• A standard indirect cylinder

• A thermostatic radiator valve

What is this?

• A diverter valve

• A thermostatic radiator valve

• A gas valve

• A pressure release valve

What is the purpose of a filling loop/valve?

• To increase the pressure within the boiler

• To allow gas into the boiler

• To let the water in the system to go around in a circle

• To allow de-icer to flow into the system to prevent frozen pipes

What is this and what does it do?

• A GV - allows gas to flow back and forth into the radiators

• A TRV - controls the temperature within the boiler

• A PRY - allows water to flow through the main inlet pipe and through the colander

• A DV - to divert heated water between two main demands

What is the main function of a boiler in a central heating system?

• To store hot water for later use

• To heat water and supply it to radiators and taps

• To control the pressure in the system

• To divert water between different circuits

Which device is used to release excess pressure from a heating system to prevent damage?

• Thermostatic radiator valve

• Pressure release valve

• Diverter valve

• Indirect cylinder

What is a HEX and it's purpose?

• The Heat Exchanger - a component that will allow the transfer of heat from ignited gases to cooler water

• The High Extender - a plastic connection between the PCB and thermostat

• The Huge Expansion Vessel - a particularly large expansion vessel connected to the boiler to allow for steam to condense

• The Hex - a terrible curse that will cause a boiler to fall off the wall

What is this and what does it do?

• A gas valve - allows gas to flow back and forth into the radiators

• The flue - pushes exhaust gases into the home

• The boiler pump - circulates hot water around the heating system

• An expansion vessel - pushes steam into the central heating system

Which component in a central heating system is responsible for sensing and regulating room temperature?

• Filling loop

• Expansion vessel

• Boiler pump

• Thermostat

Which part of the heating system is designed to store hot water for later use?

• Heat exchanger

• Thermostatic radiator valve

• Indirect cylinder

• Boiler pump
