This video will show you how to safely remove a radiator from a wall so you can paint behind.




This video shows you how to remove a radiator when you want to paint a wall and behind the radiator. It’s really easy and all you’ll need is a shallow tray, an adjustable spanner, some grips and a few towels. We show you how to shut off the radiator and make sure the valves hold, and how to drain the radiator. Finally showing you how to remove the valves and lift the radiator off it’s brackets.

We’re going to show you how to remove this radiator without having to drain the system down so you can basically take it off the wall and quickly paint behind it. So, it’s a really handy trick to know how to get these off without having to drain the whole system out. So, very simple video.

Oh, yeah, and remember one thing as well, if you don’t have enough flex on the radiator pipes going up, say they’re coming out of a concrete floor, this might not be the easiest job to do in the world. So, you know, make sure that the pipes can move a little bit, if you can, before you start.

So, first things first, what you’re going to need to do is make a note if you got a pressurized heating system. That is where you have the little dial on front of the boiler or up in your loft in your airing cupboard. Make a mental note of where that dial is pointing because once you finish this job and you put the old radiator back on the wall, you’re going to need to, probably, re-pressurize the system a little bit, just top it up a little bit and also you might need to add a small amount of inhibitor.

We’ve also done a video on how you can do that so please check our YouTube channel, type in inhibitor, and you’ll find a way that you can do that there. So, first, the tools you’re going to need for this job, we got a spanner here, a normal spanner, we got ourselves a pair of adjustable grips just in case we need to grip the radiator valve, and basically, a couple of towels, maybe a sponge if you get water everywhere. And, because you’re not going to have the specially made plumbing device for this, because we can actually have specially made plumbing trays for this sort of drain, we’re just going to use ourselves a little paint base like this today. So, you made a note if there’s a pressurized system or if you’ve got a tank in the loft, you don’t need to worry.

So, the next thing we’re going to do is shut down the lockshield into the radiator. The radiator we’ve got here today has got two lockshields on it but you might have what is called a thermostatic radiator valve, or TRV, at the other end. So, you want to shut that down to zero. So, let’s do that now. You shut this down here now. Remember, righty-tighty, OK? It’s really important to remember that. Righty- tighty. So, what that means is that you’ve turned it right to shut the valve. Let’s do this end here. Right, there we go. So, they’re both shut off now.

Now, what we need to do is get ourselves this little tool here. This is a radiator bleed key. And what we’re going to do is we’re going to pop our tray under here and a couple of our little towels to stop what we got now And we’re going to open this up and make sure that no water comes out. Sometimes, you’ll get a little bit of water come out as the pressure dissipates out the radiator but after about five minutes, it should stop. If it doesn’t stop, I’m afraid you’re not going to be able to carry on with this method of removing the radiator to paint behind the wall.

So, as you can see, we got no water coming out of here even though you might get a dribble on your radiator. All we’ve done is basically we’ve shut these two valves and now we for a fact that they’re holding. So, we know it’s safe for us to go into the next stage. All we need to do next is use our grips and adjustables to grip the valve itself and slack it off this knob on the radiator side of the valve. Choose either end, it’s up to you, but I usually use the TRV end. Because we haven’t got the TRV here today, I’m just going to use the end nearest the camera. We’re going to hold our body just like this, and then we’re going to get our nut and just loosen off this valve as so. And, you should see, pretty much straight away we get a little bit of water coming out. So, now we got a radiator draining down basically, it’s just a matter of patience.
