What are the 2 valves on 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.
Do you use less gas if you turn radiators off?
Your boiler uses up the same amount of energy however many radiators it has to heat, but by turning some of them off, your boiler will work more efficiently, meaning the rest of the house will warm up sooner so the boiler switches off sooner, and you’ll save money because you’re using less gas.

What is a bypass radiator?
Bypass valves are valves fitted to heating systems between the boiler and the radiators. They are connected between the flow and return pipes to maintain a constant minimum flow rate through the heat exchanger and to provide heat dissipation on pump overrun.
How do you turn off an old fashioned radiator?
Grip the top of the metal valve with a sturdy pair of pliers and turn it clockwise. Keep turning the valve until it doesn’t go any further. When it’s all the way to the right, the radiator is off. The metal valve may be hot so do not touch it with your bare hands.
