Turn valves clockwise to turn your radiator off and anticlockwise to turn it back on. Turning your radiators off is easy.
Is it clockwise to turn a radiator off?
Turn the radiator off: To turn your radiator off, turn the valve clockwise as far as it will go.
Which side of the radiator is the inlet?
Discovering where the valve inlets on your radiator are is fairly straight-forward and is defined primarily by the kind of radiator or heated towel rail that you have. With a heated towel rail, for example, you will normally find that the inlet position is located underneath at the bottom.
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.
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.
How do you turn off a central heating radiator?
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 find the flow side of a radiator?
Turn off the heating until it is cool. Turn it on and aim the laser alternatively at the two tails. The one that heats fastest/first is the flow.
Which way turn radiator off UK?
Turn valves clockwise to turn your radiator off and anticlockwise to turn it back on. Turning your radiators off is easy.
Which direction does water flow through a radiator?
Top to bottom. Hot water enters at the top of the radiator, and then the cool water exits at the bottom (where it’s fed back into the engine). Top to bottom is more efficient, since you’re not working against natural convection. Remember, a hot fluid rises, while a cold fluid sinks.
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.
Why can’t I turn my radiator off?
If you do not have a TRV attached to your system, there may be other reasons why your radiator will not turn off including: The valve could be stuck open due to wear and tear, a lack of maintenance, or the system may not have had any sort of thermostat installed at all.
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. For a more detailed insight, take a look at our Radiator Valve Guide.
Can a radiator be fitted wrong way round?
If you fit the radiator in the wrong orientation it can result in a reduction of output, noise from the heating system, or even in extreme cases you can end up with a radiator that doesn’t do anything other than take up wall space. This also goes for the valves.
Does it matter which way round you plumb a radiator?
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.
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.
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. Once this is done your radiator system should be fully balanced and your radiators should heat up evenly and efficiently.
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.
How do I turn my radiator on?
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.
