Can I remove a radiator permanently?
Also question is, can you leave a radiator off?
The answer to this is yes and no -- but it's all good news – yes you don't have to drain the whole central heating system but no you don't even have to connect the two pipes together. By closing the valves at both ends you can drain the water out of the radiator then take it away.
In this regard, do you need to turn the water off to remove a radiator?
1: Turning off the water supply Your first step is to turn off the central heating and allow the water in the system to cool. Next you sort out the valves at either end of the radiator or towel rail: At one end is the manual control valve that turns the heat on and off.
The time to replace a radiator varies from person to person and the skillset. A professional mechanic should be able to do it in 2 to 3 hours. A person doing it for the first time may have trouble in locating the bolts and other parts and could take the double amount of time or 7 to 8 hours.
