Why do radiators have two pipes?
Radiators normally have a threaded hole (or ‘tapping’) at each corner. The bottom two are for the valves: a manual (or ‘control’) valve to adjust the incoming flow of water (used to turn the radiator on and off), and a lockshield valve to control the outgoing flow of water (normally left fully open).
Can I connect 2 radiators in series?
One end of each radiator will have no connections. On these ends join two bottoms together and two tops together possibly best in 15mm. Piping this way will effectively create a single radiator equal in length to the two singles but more importantly will make the heating of both more even and efficient.
What thread is on a radiator?
Radiators usually have a 1/2 inch BSP female threaded connection for the valve (see BSPT link at bottom of page for more info on plumbing thread sizes).
Can you daisy chain radiators?
Connecting your radiators using a one-pipe system Radiators connected by way of a one-pipe system operate in accordance with the principle of a daisy chain. This means the return water of one radiator serves as the supply water of the next radiator unit.
What size thread is a radiator bleed valve?
Radiator Air Vent Bleeder Brass 1/8″ BSP 8.56mm Diameter Thread.
Are all radiator valves the same size?
What Size Radiator Valve Do I require? 15mm valves are the only size you’re likely to encounter, since 15mm copper pipes are the most common. There are also other sizes, from 8mm to 28mm, and there are accompanying adapters.
Can you connect 3 radiators together?
3 trv’s yes. If the 600×1200 single heats the room currently then 3 x 600×400 singles would do the job. Or 1 600×600 double. There will be other options also.
Can one radiator feed another?
Normally, adding one or two new radiators doesn’t cause any problems, but to be on the safe side, it’s a good idea to check your boiler’s output and make sure it’s powerful enough to accommodate this. See our useful guide for more information about choosing the right boiler for your home.
What kind of thread does a radiator valve use?
The tappings in a radiator are usually a standard 1/2 inch BSP female thread (see BSPT link at bottom of page for more info on plumbing thread sizes). Some radiator valves use a large union nut and tail, and others use a 15mm compression connection to the tail.
What kind of connection does a radiator have?
Each radiator is manufactured with six ½” BSP threaded connections, as shown in the illustration above, one of which has a factory installed integral thermostatic valve/adjustable flow-setter, another, a manual air vent, two with drain plugs and a bottom supply and return connection.
Can you change the thread on a radiator?
All of these replacements go into the radiator OK, but none of them then screw on to the existing radiator valves. The thread just catches, but it does not do 1 complete turn. Even with a spanner I can only just get it to do about 1 full turn before it stops.
Can a towel rail fit a radiator valve?
Not open for further replies. I recently purchased a new towel rail but could not fit the two valves [Thermostatic and on/off] as the threads on the valve and radiator did not match up. The valves were purchased separately from the radiator but I did not see this as an issue.

What’s the standard thread size on a radiator?
Standard is 1/2 inch bsp but on older radiators it can be 3/4 in BSP.
Is the nut on my radiator big enough?
The part that actually screws into the radiator itself is fine, it’s 1/2″ thread screws into the radiator without problems. It’s the other end of this part that screws onto the existing valve that’s the problem. The valve’s thread is too small for the nut and other side of the radiator part to fit flush with the O ring.
Can a 10mm radiator be fitted with a 15mm valve?
The 10mm & 15mm issue is now clear though so thanks for that. The part that actually screws into the radiator itself is fine, it’s 1/2″ thread screws into the radiator without problems. It’s the other end of this part that screws onto the existing valve that’s the problem.
