To me that is another RCBO And way used up. For what?

Looking for a smarter way to manage your heating this winter? We’ve been testing the new Aqara Radiator Thermostat W600 to see how quiet, accurate and easy it is to use around the home. Click here read our review.
Am I on ring or radial sockets (test results included)

In addition to which, you have to be more careful, of which sockets you are plugging those heaters into - not something the average user will understand.

During Covid I installed a radial via a 13 amp fuse for a printer & laptop in a temporary office to separate staff, about two days later I was called out for a power failure, four gang extension with a kettle and toaster were plugged in
Loving the cultists out there... when your heating fails out come the 4 heaters and therefore you need 32amp rings.. whilst on planet under 70 nobody has 4 heaters anymore, most people are lucky to have one. More likely these days is when my 32amp ring gets a fault my house goes off, when one of my 20amp radial fails I plug my stuff into the other one and keep going.
Argos have stocks of heaters.
Why do your 20A radials fail?
Why do your 20A radials fail?
Same reason anything fails... a fault but takes two faults to kill two independent radials but only one to kill a ring....
Doesn't that also double the chances of one failing?
Generally, friends and neighbours, even charities, will rally round and provide spare electric heaters if they are needed. So no need to go buying
Sorry harry but I cannot fathom how it doubles a chance... 1 fault is one fault, roll a dice does the chance of rolling two sixes increase or decrease if you roll a six first or is it exactly the same chance 1 in 6.
That's not necessarily true.
There could be one fault on a ring which might not be noticed but which makes it dangerous.
It would take two faults to kill part of it.
So there is a fault that has made a ring into an unkown dangerous fault, 32amps down two legs ?.... which one is the safer ? the ring that now pumps out 32amps down two now independent 2.5mm legs..... or the one where sockets / socket stop working after the fault. But there are quite a few other faults that would do the job..
Just plugged in my heater oops its faulty ring trips now house without power, but on two independent radials only one would trip...half the house has power.... its not difficult.
Rings are an abomination made of need... and we don't have that need now do we ?
I was not disagreeing with your general dislike of rings; just pointing out that a ring with one fault might make it dangerous instead of dead.
A radial circuit, with a poorly made termination, might equally prove to be dangerous, similarly.

Not really.
Not always I`m afraid - On a radial any live disconnection will stop all sockets that side of the fault stop working, yes a good thing. However the downside is a disconnection on the Earth conductor alone will still allow all of those sockets to work but without an earth and therefore unnoticeable.
Result, No protective earth available at one or more sockets any any earth fault puts a Live voltage at one or more appliances all of which remain unnoticeable until OUCH!
(Unless you have a "High Integrity Earth" on that circuit).
Not only does the faulty washing machine become live but also the dryer, dishwasher, fridge, freezer etc etc.
One reason for the statement about Ring V Radial being swings and roundabouts.
