They seem to have made a lot of addvancment with wall mounted electric radiators but, if you had one in every room like gas heating and (all) switched on at the same time, would it  not be dangerous pulling that amount of current through your sockets in one go. Plus, anyone using these. Thanks

I don't think it would be dangerous. Maybe there should be a dedicated circuit with an appropriate fuse or trip at the main 'fuse board'. Builder can probably post a more educated reply.

Thanks, could well be, but a lot of them appear to be just plug in and go. Some appear to be hard wired. The hard wired may well be the dedicated circuit.

If the radiators are of a plug-in type, they can't be pulling more than 13 amps each. 

A small house might have just one 32 amp ring circuit for the ground floor and one for the upper floor but that still allows for two such radiators per floor (plus other devices plugged into the circuits as well). 

In practice the thermostats on the heaters would be switching them on and off frequently, so it's highly unlikely that they'd all be drawing current together.  (If they were constantly drawing maximum power together then, at £2.70 per hour, the householder is going to have some massive bills!).

Larger houses tend to have several 32 amp ring circuits on each floor.  So there shouldn't be any problems with having several radiators plugged in simultaneously.

Thanks Buen. Looking at some of the sales patter and cost claims, I get the feeling they are not being totally honest :0). They maybe ideal for a small space room, where you have no radiator and just need heat now and again.

Nothing to worry about concerning safety Nicey. All circuits should incorporate an 'overcurrent' device. Either an MCB (miniature circuit breaker) or a fuse. This applies to 'ring' circuits and dedicated radial circuits.

Most panel heaters draw less current than your kettle. If you do have too many running at one time, they'll run for a while and then the MCB will disconnect.
