What is this component and what is its purpose
A Thermostatic radiator valve controls the water temperature of a radiator
A Thermostatic radiator valve controls the air temperature of the area around the radiator
A Thermostatic radiator valve controls the water temperature of the boiler
A Lock shield radiator valve controls the water temperature of a radiator
Name this component
Lockshield valve
Wheel head valve
Thermostatic valve
Blending valve
What is the correct name for this radiator valve
Lockshield valve
Filing valve
Thermostatic valve with built in drain off valve
Lockshield valve with a built-in drain off valve
What is the purpose of a lock shield valve
To balance each radiator so the system gets equal heat flow to each radiator
To turn the radiator off when the room get warm enough
To allow the radiator to be turned of for removal
To balance the temperature of the radiator
What is this tool used for
Draining down the heating system
Fitting tap washer in taps
Fitting radiator valve stems to the radiator
Fitting radiator brackets
Why are there numbers in the thermostatic radiator valve head
These determine the air temperature which the valve will close
These determine the temperature which the valve will turn off the boiler
These determine the temperature which the water will be in the radiator
These determine the pressure of the water
What is the component called and what does it do
Central heating circulation pump it circulates water to the radiators
Central heating circulation pump it circulates warm air to the radiators
Central heating booster pump it circulates water to the radiators
Central heating circulation pump it circulates water to the hot taps
What is this component use for
Removing water from the radiator
Removing air from the radiator
Removing sludge from the radiator
Removing air from the boiler
What is this component and where does it go
Drain plug , goes at the bottom of a radiator
Air vent plug goes at the top of the radiator
Air vent plug goes at the bottom of the radiator
Blanking plug goes at the top of the radiator
What are these
Inhibitors added to a central heating system to protect components form corrosion
Inhibitors added to a central heating system to protect components form leaking
Inhibitors added to a central heating system to make the water get hotter
Inhibitors added to a central heating system to prevent the water getting too hot
Radiators are normally positioned 150mm off the floor- what is the reason for this
So a vacuum cleaner can fit underneath for cleaning purposes
For air flow so cold air can be drawn up through the radiator for convectional currents to circulate
So the pipes can fit snuggly underneath
Its easier to install it than putting it lower
When filling up a radiator what needs to be done before turning on the pump and boiler
Removing the air from the top of the radiator
Turning both valves off
Make sure the room thermostat is set to a high temperature
Adding an inhibitor to the system
What is applied to the threads of the radiator valve stems before screwing them into the radiators
Boss white
PTFE tape
Hemp
String
What is this component and what is its purpose
A hot water thermostat and governs the temperature of the hot water and turns off the boiler
A room thermostat it governs the ambient air temperature and turns off the central heating when it senses the pre-set temperature
A room thermostat it governs the water temperature and turns off the central heating when it senses the pre-set temperature
A room thermostat it governs the temperature of the radiators and turns off the central heating when it senses the pre-set temperature
