How do straight radiator valves work?
These valves are more sophisticated radiator valves and the way that these work is that they are set to a certain level, and once that level is reached, the valves automatically stops the flow of water into the radiator, helping to maintain the overall temperature desired.
Which way do you turn a manual radiator valve?
Step 1: Also known as a manual valve, find the non-thermostatic valve on the left or right side at the bottom of your radiator. The other valve on the radiator will be fixed or will be capped. Step 2: To turn your radiator off, turn the valve clockwise as far as it will go.
What is the manual valve on a radiator?
Manual radiator valves are angled taps on your radiator which are there merely to turn the radiator on and off. In a manual radiator valve system, the radiator control is down to the thermostat, located elsewhere and off the radiator body.
How do you use traditional radiator valves?
Manual Radiator Valves Explained One of the easiest to use valve available, you just need to twist the top with your hand and it alters the flow of heat into your radiator - simple, just like turning a tap. They will tend to be simpler, and usually far smaller than thermostatic valves.
Do both valves on a radiator need to be open?
You should open both of the valves on all of your system's radiator when you are starting the radiator balancing process. You will most likely need to use pliers to open the lockshield valve.

What is the difference between thermostatic and manual radiator valves?
A thermostatic valve or TRV as it is often called will shut off the radiator if the temperature has been reached for the room, whereas a manual valve will only close if you physically go and turn it off. Basically a manual valve is either on or off and there is no much in-between.
Why are there 2 valves on a radiator?
Each radiator will have two valves. One will control the amount of hot water that enters the radiator and the other will balance the system by controlling how much heat comes out of your radiator.
Which side of a radiator turns it off?
To turn a radiator off, locate the thermostatic valve on the left side and turn the valve clockwise until the dial reads 0. Next, find the second valve on the right side of the radiator and twist it clockwise until it won't turn anymore. Once both valves are closed, the radiator will be completely turned off.
How do you control the heat on an old radiator?
You can adjust the heat by turning the thermostatic valve. Look for it on the side of the radiator. The thermostatic valve usually has a taller cap with numbers ranging from 0 to 5 on it. Adjust the dial counterclockwise to increase the heat and clockwise to reduce it.
How do traditional thermostatic valves work?
The thermostatic valve head goes on top of the valve body. And as the room temperature changes, the valve head expands, adjusting a pin in the valve body so that it opens or closes. Expansion as the room heats blocks the valve body to receive less hot water into the radiator.
What position should radiator valves be in?
Many modern homes will have TRVs – Thermostatic Radiator Valves – attached to most of the radiators on the opposite side from the lockshield valves. A TRV should always be fitted to the inlet on the radiator and the LSV to the outlet.
What does a radiator valve do?
Each radiator in your home needs a pair of radiator valves which act like taps, enabling you to control how much heat they give out. One of the valves controls the amount of hot water entering the radiator and the other (known as the lockshield valve) balances the system by controlling how much heat the radiator emits.
What is the purpose of turning a radiator valve?
Turning the valve adjusts the amount of hot water flowing through the radiator and therefore how much heat is emitted. Manual valves are the simplest to operate and tend to be smaller than thermostatic valves.
What is the difference between straight and angle radiators?
Straight Radiator Valves have no bends meaning your water will flow straight either along a wall or up from the floor. Angled Radiator Valves have a 90° bend which means it can connect the pipework with the radiator at an angle.
What does it mean when a radiator has a middle valve?
More modern radiators may have middle connection valves (in the centre, at the bottom). This means you don't have valves and pipework sticking out at the side so can be a great space saver.
How to ensure TRVs are working?
To ensure TRVs have the best chance to do their job and keep your heating system working effectively you should check that your heating system is balanced. This means ensuring the flow of hot water is evenly distributed around your home so radiators heat up at the same rate.
What temperature should a radiator valve be?
Generally speaking, turning the valve to number 3 should result in a room temperature of around 20°C with each number above / below representing a degree.
What does a TRV valve do?
The TRV includes some wax or liquid which can 'sense' the temperature in the room; when your desired temperature has been reached the TRV will shut off the flow of hot water and stop the radiator getting any hotter.
What is a thermostatic radiator valve?
Thermostatic radiator valves (TRVs) give you much more control over the temperature in your home because they have more advanced features. Like a manual valve, you can set the valve to what temperature you’d like a room to be.
What is the most common radiator valve?
The most common type of radiator valve is a manual radiator valve. The clue to how manual valves work is in the name - you have to turn them to control the temperature.
What is the pipe system?
The pipe system is the way your pipes run throughout your home. They could be buried within the wall, under the floorboards, or they could be fully external, running along the walls of your home and in plain view.
Types of radiator valves
Functionally, there are three main types of radiator valves in terms of how they work: Smart, Thermostatic and Manual. But don’t let the names fool you, they all have a significant and defined purpose in your home, and you need to know about all three.
How your radiator valves function
So you may have been told that installing thermostatic radiator valves in your rooms is the best way to go because you can save on heating bills. While this is true, there is always at least one room that needs a manual valve in your home, so let’s start with how your radiator valves function before we go onto shape and pipe connections.
The shape of your radiator valves matter
Now you know how each of our radiator valves can function, it’s time to connect our radiator to our pipes. To do this, we need the right valve shape, so let’s look at the best uses for different radiator valve shapes.
One last thing to consider
Our radiator valves will fit all rads and towel rails in the UK, so the only other thing to consider is your pipe size. Our valves come in pipe connection sizes of 8mm, 10mm and 15mm which you will need to match with your pipes.
