This is a question our experts keep getting from time to time. Now, we have got the complete detailed explanation and answer for everyone, who is interested!
The vast majority of contemporary thermostatic radiator valves are bi-directional, meaning that they can be installed on either the flow pipe or the return pipe of a radiator. Yet, the TRV should ideally be installed on the flow pipe that leads into your radiator. This is the recommended method.
Which direction does the lockshield valve face: the flow or the return?
Adjusting the lockshield valves that are typically installed on the return side of each radiator is the standard method for achieving system balance. This guarantees that each radiator circuit in the system has an equal pressure drop and receives the appropriate flow of hot water to heat the space in which it is placed. Also, this ensures that the space can be heated effectively.
Where should the TRV be located, the inlet or the outlet?
Although the vast majority of modern TRVs are bidirectional and can be installed on either the flow or the return side of the system, installing them on the flow side is the recommended best practice. If a TRV that is not bidirectional is installed on the return side of the system, the water will cause it to vibrate and make a noise as it attempts to flow through it.
How do I know which direction to spin a TRV?
Step 1: The valve on a TRV radiator is typically located on the left-hand side of the radiator. The valve that you are looking for will have a numbered dial on it, and it will typically be located on the bottom of the radiator. This dial will allow you to alter the amount of heat that the radiator emits. Step 2: To shut off the valve, rotate the dial counterclockwise until it reads 0 on the face of the dial.
On which side of a radiator is the thermostatic valve supposed to be placed?
The thermostatic valve head is attached to the valve body at its uppermost position. In addition, if you change the temperature of the room, the valve head will expand, which will cause a pin to move within the valve body, causing the valve to either open or close. As the temperature rises in the room, the expansion that occurs blocks the valve body, causing the radiator to receive less hot water.
How do I know which radiator valve to turn, in what direction, and which one controls the flow?

Does the fluid in the radiator move in a particular direction?
When viewed either standing up or affixed to the wall, the flow of a radiator is normally on the left side of the appliance.
Why does a radiator have two valves of its own?
The amount of hot water that is allowed to enter the radiator is controlled by a single valve… The other valve, which is known as the lockshield valve, is responsible for maintaining the system’s equilibrium by controlling the amount of heat that the radiator emits.
Is it appropriate to turn off the radiators in rooms that are not being used?
Also, because doing so can result in condensation and mold growth, turning off a radiator in a room that is not being used should be avoided. Instead, turn them down to a low setting and close the doors.
Should the valves on the radiator be open or closed?
If you open the valve, more hot water will be able to run through the radiator, which will cause it to warm up more quickly. When the valve is closed, the flow of hot water is restricted, which results in the radiator not warming up quite as quickly.
What causes thermostatic radiator valves to become defective?
If you can’t believe it, the most common reason a thermostatic radiator valve isn’t functioning properly is because it’s been set to the incorrect number or turned off totally…. If you feel that the temperature in the room is too high at this point, adjust the TRV so that it is one mark lower, and then check the temperature again the next day.
Are universal TRV heads available?
Your T.R.V. heads are not universal in any way; i carry three different varieties, and there are many more available.
The arrows on the TRV… what do they mean?
They were designed with a simple arrow that pointed in one direction to indicate the flow of water. It was necessary to configure them in such a way that the flow of water through them would correspond to the pointing arrow. This meant that they were typically attached to the flow pipe in some manner… Up until the year 1995, virtually all TRVs were installed directly onto the flow pipe.
What what is a two-way TRV?
The series of thermostatic radiator valves offered by Myson, specifically the TRV 2-way, is the most comprehensive option currently on the market for modern central heating systems. The MYSON TRV 2-way, which incorporates our one-of-a-kind “2-way” engineering and our exclusive, patent-protected “bonded” method, streamlines the installation process and eliminates the possibility of expensive callbacks.
What happens if the TRV is installed on the incorrect side of the radiator?
If the TRV is located on the flow side of the radiator (like the rest of your house), then when it closes, it prevents water from entering the radiator. If the TRV is located on the return side of the radiator, then when it closes, it prevents water from leaving the radiator. If water is unable to leave the radiator, then it will not be possible for water to enter the radiator. In this case, the system will function correctly regardless of which side it is located on.
How much should I turn a lockshield valve clockwise to open it?
It is recommended that you turn the Lockshield valve on the first radiator a quarter of a turn clockwise to open it. Next, turn the Lockshield valve on the radiator that was at the end of your list. The Lockshield valve on each successive radiator should have a slightly greater amount of its opening exposed than the one before it.
In the context of central heating, what exactly are flow and return?
What Flow and Return Pipes on a Boiler Are and Do This newly heated water is pumped out of the flow pipe and distributed throughout the rest of your central heating system. The boiler is responsible for the initial heating of the water. After that, the water circulates throughout your heating system until it reaches the return pipe, at which point it goes back to the boiler.
What causes certain radiators to have a higher temperature than others?
On occasion, certain radiators will reach significantly higher temperatures than others. When anything like this occurs, it almost always indicates that your home’s central heating system is off-kilter… With an unbalanced heating system, the radiators that are located closest to the boiler or other source of heat may get a significantly higher temperature than the radiators that are located further away.
Why is there just room for one radiator that does not have a thermostat?
The thermostat is responsible for controlling the boiler and turning it off when the air temperature reaches the preset level. The boiler is not under the control of the radiator valves, and there ought to be at least one radiator that is on at all times.
Should radiators be made larger than necessary?
Rule-of-thumb procedures typically result in the radiator being outrageously enormous in order to ensure that there are no complaints regarding the space remaining cold. But, what no one ever tells you is that a radiator that is grossly excessive might result in other issues within the system.
Does it cost more to turn the heat on and off repeatedly?
ANSWER: It is not cost effective to turn your heat on and off frequently since your system will have to work much harder and for a longer period of time in order to bring the temperature back up.
Is it possible to turn off the water while maintaining the temperature of the central heating?
But, if you are going to be away from the house for more than a few days, you should probably turn off the water but leave the heating on. This is the case even if you plan on leaving the heating on. It’s a good idea to keep the thermostat on your central heating system set to a somewhat low temperature while you’re away from the house.
Is it more cost effective to have the radiators on the lowest setting?
The concept that it is more cost effective to have the thermostat set at a low setting all day is a fallacy, say the professionals at the Energy Saving Trust…. According to the Energy Saving Trust, if you keep the heater on throughout the day, you are wasting energy throughout the day. Because of this, it is recommended that you only heat your home when it is necessary to do so.
What’s the difference between a radiator valve and a lockshield?
It is possible to fine-tune the output of your heating system by adjusting the lockshield valve, which is located on the side of the radiator that is opposite the on/off valve. After the setting has been modified, the lockshield itself is the plastic cap that covers the valve. This cap ensures that the setting will not be altered by accident in the future.
Does turning off some radiators result in a cost savings?
A. If you turn off the radiators in the areas of your home that are not being used, you will almost surely be able to save money on your heating bill…. Moreover, make sure that any unheated rooms have their doors shut in order to prevent the warm air from the heated rooms or spaces from leaking into the unheated areas.
Without a thermometer, what steps should I take to balance my radiator?
Remove the cap from the end of each radiator that is opposite the on/off knob, and then open the valve all the way by turning it counterclockwise, as if you were turning a tap. To remove certain caps, you will need a Phillips screwdriver, while others can be removed by just pulling them off. Wait for around five minutes to give the radiators time to warm up.
