The vast majority of new TRV’s are bidirectional and can be fitted to either the flow or return, but it is always good practice to fit them to the flow side. If a non bidirectional TRV is fitted on the return side it will create a vibrating sound as the water tries to flow though it.
Can you put radiator valves on the wrong way?
Some valves are bi-directional (meaning that water can flow through them in both directions) and others aren’t. If a non bi directional valve is fitted the wrong way round you will get a hammering noise from the valve when it is opening and closing. While this doesn’t cause any damage to the system it is very annoying.
Which way do radiator valves go?
Turn valves clockwise to turn your radiator off and anticlockwise to turn it back on. Turning your radiators off is easy.
Which side of radiator is flow?
left
The flow of a radiator is typically on the left as you look at it stood up or attached to the wall.
How do you know which side of the radiator is Inlet?
Radiator Valve Inlet Positions
Finding out where the valve inlets are located on your radiator is fairly straight forward and is defined by the type of radiator you have. For example, you tend to find the valve inlet on a towel rail radiator located underneath the bottom of the radiator.
Does it matter which side of radiator flow and return?
The vast majority of new TRV’s are bidirectional and can be fitted to either the flow or return, but it is always good practice to fit them to the flow side. If a non bidirectional TRV is fitted on the return side it will create a vibrating sound as the water tries to flow though it.
What side of the radiator is the lockshield valve?
The lockshield valve, on the side of the radiator opposite the on/off valve, may be adjusted to balance the output of your heating system. The lockshield itself is the plastic cap that covers the valve to ensure that you don’t accidentally change the setting once you’ve adjusted it.
Which valve is which on a radiator?
One valve accounts for the amount of hot water that enters the radiator. The other valve, referred to as the lockshield valve, balances the system by regulating how much heat the radiator gives off.
Should radiator valves be open or closed?
When you take the temperature of your radiator and valves you’ll be making tiny adjustments.You close the first radiator’s valve and then open it gradually until you have reached the desired temperature. If your radiators are not balanced, it will be harder to achieve the desired temperature if they are already on.
Do you bleed a radiator when it is on or off?
Turn off your heating. You can’t bleed a radiator when the heating is on, as it may be too hot to touch. You could also get hot water spraying out of the radiator. Use your radiator key to turn the valve at the top of the radiator.
Why is one side of my radiator cold?
One cold radiator usually indicates that either there is air in the system or there is a stuck valve within that radiator.This is particularly the case in an old radiator. To check if the valve is stuck, you can remove the rotatable head on the TRV to reveal a raised pin beneath it.
Which end of a radiator is the feed?
Feed and return pipes.
The heated water from the boiler is fed to one side of every radiator (the feed pipe) while the other end of each radiator is connected to a separate common return pipe.
Should lockshield valve be fully open?
Most lockshield valves have a plastic or metal cover. You should remove these and open all of the lockshield valves completely. This requires that you turn them anticlockwise. You should also fully open the TRVs (thermostatic radiator valves).
Is radiator valve same as lockshield?
The Lockshield valve restricts hot water flow to radiators to help balance the entire system as a whole. Other radiator valves can be used to help adjust the temperature of a radiator to help heat or cool a room.In doing so, you will be able to pick the radiator and radiator valve that is most suitable for your needs.
Can a radiator have two lockshield valves?
As long as there is other radiators on the system and they aren’t all closed down you shouldn’t have a problem.
Are all radiator valves the same size?
What Size Radiator Valve Do I require?15mm valves are the only size you‘re likely to encounter, since 15mm copper pipes are the most common. There are also other sizes, from 8mm to 28mm, and there are accompanying adapters.
What is the difference between straight and angled radiator valves?
Radiator Valve Shapes
The name just describes the shape of the valve and how it connects the radiator to the pipework. For example, angled radiator valves connect the pipework to the radiator at a 90-degree angle. Straight valves have no bends or curves and connect the pipework either horizontally or vertically.
Are radiator valves universal?
The connection between your valve and the radiator is standard across all moderns radiators and valves. The size differences listed above refers to the width of your pipes that the valves will slot onto.
Do both valves need to be open on a radiator?
Radiators typically have two valves located on the pipes that allow hot water to enter them.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.
Should I open my radiator all the way?
“It’s not designed to be a control valve,” he says. Typically you turn the knob clockwise to turn the heat off, counter-clockwise all the way to turn the heat on. If the radiator is off, it shouldn’t make any banging sounds. “When you have it opened halfway, that can lead to banging problems,” Varsalona says.
Which way does a radiator lockshield valve open?
Turn the lockshield valve clockwise until it is closed and then open it by a quarter of a turn. Once the radiator has warmed up, take a temperature reading at the pipework leading to one of the valves (7).
