What are the two valves on a towel radiator for?

The valves in a towel radiator control the flow of water through the pipes. This ensures your radiator heats up effectively and efficiently. They keep your towel radiator functioning and ensure that your bathroom is heated up when needed, and your towels are dry and ready to use.

What are the two valves on a heated towel rail?

Your towel radiator has two valves to enable it to control the flow of hot water and the amount of heat it emits. One valve regulates the amount of hot water entering the towel radiator while the other controls the rate at which the hot water exits the radiator.

Should both valves be open on a radiator?

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 is the lockshield valve on a towel radiator?

A lockshield valve is the valve on a radiator that has a plastic cap covering but not connected to the adjusting spindle. If you turn the cap it doesn't adjust the valve. To adjust the valve you have to remove the cap and turn the spindle with pliers.

Do you open both valves on a towel rail?

Open both fully anticlockwise. Should heat up then ,providing central heating is on.

How to fit towel radiator valve. Towel radiator valve plumbing.

Should all lockshield valves 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).

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 are the valves on both sides of 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. For a more detailed insight, take a look at our Radiator Valve Guide.

Are both radiator valves the same?

Generally, there are two different style radiator valves (that are adjustable by the user) available. These are manual valves and Thermostatic Radiator Valves (also known as TRVs). Manual valves are quite simple devices that you can think of like a tap in your home.

What do valves on bottom of towel rail do?

What do towel radiator valves do? The valves in a towel radiator control the flow of water through the pipes. This ensures your radiator heats up effectively and efficiently. They keep your towel radiator functioning and ensure that your bathroom is heated up when needed, and your towels are dry and ready to use.

Where is the bleed valve on my towel radiator?

Find the towel radiator bleed valve. It tends to be at the top of the towel rail but is sometimes at the back. The screws are generally hexagonal or square. Also, many of them have a slot across the front so you can use a slotted screwdriver if a radiator key isn't available.

Should radiator valves be open or closed?

A Lockshield valve is used to adjust how quickly a radiator takes before warming up – opening means more hot water flows through quicker whereas closing slows down the heating process, so things do not get too hot too fast.

Do heated towel rails stay on all the time?

Heated towel rails can be left on continuously, like standard radiators but if you have an electrically heated towel rail it is better and safer to limit usage and turn them on only when needed, rather than leaving it on all the time.

How far open should radiator valve be?

You should open the Lockshield valve on the first radiator by one-quarter of a turn. Now open the Lockshield valve on the last radiator on your list. Each radiator in between should have its Lockshield valve opened slightly more than the previous radiator.

Do I need lockshield valve?

A lockshield valve helps to balance out that radiator and ensure the whole system is in sync, with all radiators heating at the same rate. It is therefore every bit as important a valve as without the system being balanced, there is often little point adjusting an individual temperature valve.

What does the lockshield valve on a radiator do?

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.

How do I adjust the heat on my 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 you open the lockshield valve on a radiator?

Once the system has cooled down, you will have to open the lockshield valve. To do this, simply turn in an anti-clockwise direction (to the left). You can do so by hand; but if your valves are a bit stiff, use your lockshield valve key, a spanner, or the wheelhead valve cap instead.

Is it safe to close radiator valve?

Radiator valves, even though they have a handle, are not meant to be closed or half-open. Closing or opening the valve partially, will not control the heat coming from your radiator. Steam radiator valves must remain fully open at all times.

What happens if a lockshield valve is closed?

On most radiators, this is the valve you can't turn by hand. By closing a fully-open lockshield valve by a few turns (with a pair of grips or screwdriver), you can slow down the rate at which water enters the radiator and reduce the speed with which it gets hot.

Which side should lockshield valve be?

Systems are normally balanced by adjusting the lockshield valves usually fitted on the return side of each radiator. This ensures that each radiator circuit in the system has an equal pressure drop and receives the correct flow of hot water to heat the space in which it is fitted.
