What does each valve on a radiator do?
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.
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 some radiators have two valves?
The reason you need two valves generally on all rads is because the system dictates a flow and return. The flow pipework carries the newly heated water from the boiler. The return taking it back at a lower temperature to be reheated by the boiler.
What are the different valves on a radiator?
The different types of radiator valve are:Thermostatic Radiator Valve.Manual Radiator Valve.Dual-Fuel Radiator Valve.Traditional Radiator Valve.Modern Radiator Valve.Straight Radiator Valve.Angled Radiator Valve.Corner Radiator Valve.
Should 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 happens if 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.
What does lockshield valve 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.
Which way do you turn a lockshield valve?
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.
Do all radiators have 2 valves?
Every radiator in your home has a pair of radiator valves to control the heat output. Even if you have a thermostat to control the central heating, the valves control each radiator.
Which side of a radiator turns it off?
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.
Do all radiators have a lockshield valve?
Unless your radiators have TRVs fitted, they will usually have a wheelhead and a lockshield valve, one on each end.
