Product Information

BES will help you find the right radiator accessories for the job at hand. You might find yourself needing a key to let the air out and help balance a system.

Whatever possible radiator issue you have, BES should have the product to help. We have a wide range of radiator accessories on offer, including: In this case, the size of the radiator valve refers to the size of the valve connection and pipework instead of the design of the valve. Draining and refilling a heating system is an ideal time for air to get trapped in the heating system. So it's a good idea to bleed the radiators. Cover the floor area around the radiator under the valves you are going to replace with the towels and container to catch any excess water. Once they’re tight (but not overly done) remove the protective cap from the top of the valve body - this is usually screwed on so simply unscrew it. Now take the top of the valve and connect it to the valve body. Once it’s on you’ll want to just gently tighten up the nut a little, be careful not to over tighten it. If you're using tools to tighten up nuts then you could use a bit of cloth so that the finish of the valve isn't damaged in anyway.

Work in a clean area, having a towel or a cloth handy will enable you to keep the area and floors dry and safe for any job Since radiator valves play a significant part in how well central heating radiators operate, and as most of them are visibly on show in our homes, changing your radiator valves is a great way to improve the performance, efficiency and overall look of your heating system.Step 4: Make up the valve, ensuring the retaining nut and olive are on the pipe. Position the new valve body suitably angled/aligned for your radiator's tails and hand-tighten the connections. Tighten everything up using a suitable pair of grips or wrenches, and ensure the valve is actually closed. The standard size of copper pipework is 15mm and all of our radiator valves have a half inch (½”) thread on the bottom (the part that connects the valve to the pipe) which makes them suitable for use with 15mm piping.

Since the radiator has been drained and refilled you will need to re-pressurise the system to ensure everything is working correctly. Then take the new thermostatic valve head and screw it onto the valve. You should be able to do this by hand. We can take you through how to change radiator valves in 7 steps. But first there are a few things you'll need to hand:

As the water is flowing, keep a close eye on the pressure gauge. The needle will move up as the water levels in the system rise and you don't want the pressure to be too high. Now you need to remove any trapped air inside the radiator. This is called bleeding the radiator. There may also be air trapped in the nearest radiator, so it is best to bleed that one too. Changing a radiator valve can be a DIY job but we strongly advise getting a professional in. Will the heating system need to be drained? Fit the body of the TRV to the radiator and pipe. Use the wrench to tighten the nuts right up on each side. Now you can simply screw the head of the TRV onto the body. 6. Close the bleed valves But don’t worry if your pipes are slightly bigger or smaller than the standard 15mm. Sometimes copper pipes can be anything between 8mm – 28mm depending on where they are in your home and the age of the building.

Fit the new chrome radiator tail where the old one was removed and remember to use PTFE tape if you want to minimise risks of leaks. Slide the nut and olive onto the radiator tail. Locate your water pipe and then slide on the nut and then attach the olive. Take your new radiator valve body and connect it to the water pipe whilst lining it up and inserting it into the radiator tail. This can be a bit fiddly so please be patient.

Radiator valve sizing is the diameter of the connection and pipework. Rather than the height of the valve. Updating your radiator valves can have many benefits on your home heating and your home decor. Here’s why: Changing a radiator valve is easy when you follow these 6 simple steps. If you don’t need to remove a radiator valve and just want to fit a new valve to an existing pipe and radiator then jump to step 4.
