What are the 2 valves on a towel 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.

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.

What do the two valves on a towel rail 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.

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.

Why do radiators have 2 valves?

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 Towel Rail Valve To Choose? | elegant-radiators.co.uk

How much should lockshield valve be open?

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.

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.

What side of the radiator is the lockshield valve?

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.

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.

How do you adjust the temperature on a towel radiator?

The most common method for adjusting temperature will be to adjust the knob by turning clockwise to turn off - I.e. cool or anti clockwise to open and up the heat. Turning the knob could be difficult, and so pliers might be required.

What is a lockshield valve?

As previously mentioned, a Lockshield valve is a valve on a radiator that is used to help in balancing the radiator and the central heating system as a whole. It can be opened to differing amounts to let in a certain amount of pressure - depending on where the radiator is in the house.

Should there be a thermostatic valve on every radiator?

We recommend you fit a thermostatic valve on every radiator. But there's no need to fit one in a room with a fixed room thermostat.

Do all radiators have a lockshield valve?

Lockshield Valves Explained

A lockshield valve is slightly different from manual and thermostatic valves as it controls how much water can exit a radiator. Every radiator has one, and you need them to make sure all the radiators remain balanced in your central heating system.

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.

How do you close a lockshield valve?

Close the radiator's lockshield valve by turning it fully clockwise and then re-open it anti-clockwise by a quarter of a turn. 8. As soon as the radiator has heated you should sample the temperature of the pipe which leads to one of the valves and make a note of this.

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.

Why is my towel radiator leaking?

Leaking from the body of the towel rail

Internal radiator corrosion can occur when water reacts with the metal and small shards of rust break off and settle in the bottom of radiators. This forms a sludge that, if left untreated, can eventually rust through causing small holes and leaks.

Do electric towel radiators need bleeding?

For the correct maintenance of your towel rail, you should bleed it once a year. How do you bleed a radiator? Bleeding your heated towel rail lengthens its working life and saves energy.

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.

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.
