Operating a Radiator’s Controls. Turn the radiator dial counterclockwise to turn it on. The control valve is located near the bottom of most radiators. On a steam radiator, it is the valve on top of the pipe leading into the radiator.
Which way do you turn to open a radiator valve?
Step 3 – Open All Your Radiator Valves Open up the valves on every radiator in the house by turning them anti-clockwise. Thermostatic valves or older wheel-head valves can be turned quite easily by hand but the lockshield valve will need a plastic adjuster or a spanner to open it.
Which way is on and off on a radiator?
Turn valves clockwise to turn your radiator off and anticlockwise to turn it back on. Turning your radiators off is easy.
How do I turn my radiator on?
Turn on a water-circulating radiator by rotating the control valve counterclockwise to open it. This valve must be open all the way for the radiator to reach its maximum temperature. Look for a bleed valve if the radiator doesn’t get hot.
Which way turns a radiator down?
How to turn off a radiator with non-thermostatic radiator valves Locate the valve: A non-thermostatic radiator valve can be located on either the left or the right of the radiator. Turn the radiator off: To turn your radiator off, turn the valve clockwise as far as it will go.
Does it matter which side of radiator flow and return?
Most modern thermostatic radiator valves are bi-directional – so can be fitted on either the flow or return pipe of your radiator. However, it’s always best practice to fit the TRV on the flow pipe that enters your radiator.
Which side of radiator is flow?
The flow of a radiator is typically on the left as you look at it stood up or attached to the wall.
Should radiator valves be open or closed?
How to Tell if the Radiator Valve Is Open or Closed? This is a common question, but the answer is dead simple. Turn it all the way to the left, and if it won’t go anymore, it’s closed. Otherwise, it’s some degree of open.
What are the two valves on a radiator for?
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.
What are the 2 knobs on a radiator?
Each radiator in your home needs a pair of radiator valves. 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.
Do radiators have a flow direction?
The new radiator is marked for the direction of flow; through the valve and in at the top of the radiator.
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 radiator hot when turned off?
The diverter goes into a ‘mid position’, which allows the hot water to flow to both the water tank and the radiators. When a diverter fails or gets blocked with debris, hot water intended for the hot water circuit can get into the radiator circuit. Then the radiators will be hot even though the heat is turned off.
Does it matter which way round a radiator goes?
A normal radiator or towel it doesn’t matter. If the radiator is not fitted, then the tails will not heat up. Fit the radiator, if it’s the wrong way round, all you have to do is swap the rad valves round – I think the instructions will just be referring to the TRV’s, nothing to do with the radiator itself.
How do you tell which is flow and which is return?
Hi, turn the heating on and the pipe that gets hot first is the flow. Switch on your heating from cold. The pipes on the heating circuit that heats up first will the flow pipe, the other wil be the return. The Flow pipe gets warm before the return pipe.
What happens if you get flow and return the wrong way round?
If the pipes are reversed, the sensor will record the lower temperature and could compensate to make up the difference. This can result in unwanted noise, or overheating and inefficiency.
Should both sides of a radiator 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.
Which side 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.
Does one radiator always have to be on?
Yes, turn another one on, be aware of the risk that unless you lock another one open then someone else might turn it off and then you could cause an issue.
